Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License. diff --git a/COPYING.GPLv3 b/COPYING.GPLv3 new file mode 100644 index 0000000..94a9ed0 --- /dev/null +++ b/COPYING.GPLv3 @@ -0,0 +1,674 @@ + GNU GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The GNU General Public License is a free, copyleft license for +software and other kinds of works. + + The licenses for most software and other practical works are designed +to take away your freedom to share and change the works. By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License. But first, please read +. diff --git a/COPYING.LGPLv2.1 b/COPYING.LGPLv2.1 new file mode 100644 index 0000000..58af0d3 --- /dev/null +++ b/COPYING.LGPLv2.1 @@ -0,0 +1,502 @@ + GNU LESSER GENERAL PUBLIC LICENSE + Version 2.1, February 1999 + + Copyright (C) 1991, 1999 Free Software Foundation, Inc. + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + +[This is the first released version of the Lesser GPL. It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The changes are: + * The options placement is now strictly enforced! While in theory the + options for ffmpeg should be given in [input options] -i INPUT [output + options] OUTPUT order, in practice it was possible to give output options + before the -i and it mostly worked. Except when it didn't - the behavior was + a bit inconsistent. In avconv, it is not possible to mix input and output + options. All non-global options are reset after an input or output filename. + * All per-file options are now truly per-file - they apply only to the next + input or output file and specifying different values for different files + will now work properly (notably -ss and -t options). + * All per-stream options are now truly per-stream - it is possible to + specify which stream(s) should a given option apply to. See the Stream + specifiers section in the avconv manual for details. + * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the + sense that they're specified after the output filename instead of before, + like all other options. In avconv this irregularity is removed, all options + apply to the next input or output file. + * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they + irregular and highly confusing, they were also redundant. In avconv the -map + option will create new streams in the output file and map input streams to + them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for + each stream in the first input file. + * The -map option now has slightly different and more powerful syntax: + + Colons (':') are used to separate file index/stream type/stream index + instead of dots. Comma (',') is used to separate the sync stream instead + of colon.. This is done for consistency with other options. + + It's possible to specify stream type. E.g. -map 0:a:2 creates an + output stream from the third input audio stream. + + Omitting the stream index now maps all the streams of the given type, + not just the first. E.g. -map 0:s creates output streams for all the + subtitle streams in the first input file. + + Since -map can now match multiple streams, negative mappings were + introduced. Negative mappings disable some streams from an already + defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for + all the stream in the first input file, except for the second audio + stream'. + * There is a new option -c (or -codec) for choosing the decoder/encoder to + use, which allows to precisely specify target stream(s) consistently with + other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0 + libvorbis sets the codec for the first audio stream and -c copy copies all + the streams without reencoding. Old -vcodec/-acodec/-scodec options are now + aliases to -c:v/a/s + * It is now possible to precisely specify which stream should an AVOption + apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while + -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k + syntax is deprecated and will stop working soon. + * -map_chapters now takes only an input file index and applies to the next + output file. This is consistent with how all the other options work. + * -map_metadata now takes only an input metadata specifier and applies to + the next output file. Output metadata specifier is now part of the option + name, similarly to the AVOptions/map/codec feature above. + * -metadata can now be used to set metadata on streams and chapters, e.g. + -metadata:s:1 language=eng sets the language of the first stream to 'eng'. + This made -vlang/-alang/-slang options redundant, so they were removed. + * -qscale option now uses stream specifiers and applies to all streams, not + just video. I.e. plain -qscale number would now apply to all streams. To get + the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale + and -aq is now an alias for -q:a. + * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which + uses stream specifiers. Use -bsf:v/a/s instead of the old options. + * -itsscale option now uses stream specifiers, so its argument is only the + scale parameter. + * -intra option was removed, use -g 0 for the same effect. + * -psnr option was removed, use -flags +psnr for the same effect. + * -vf option is now an alias to the new -filter option, which uses stream specifiers. + * -vframes/-aframes/-dframes options are now aliases to the new -frames option. + * -vtag/-atag/-stag options are now aliases to the new -tag option. +- XMV demuxer +- Windows Media Image decoder +- LATM muxer/demuxer +- showinfo filter +- split filter +- libcdio-paranoia input device for audio CD grabbing +- select filter +- Apple ProRes decoder +- CELT in Ogg demuxing +- VC-1 interlaced decoding +- lut, lutrgb, and lutyuv filters +- boxblur filter +- Ut Video decoder +- Speex encoding via libspeex +- 4:2:2 H.264 decoding support +- 4:2:2 and 4:4:4 H.264 encoding with libx264 +- Pulseaudio input device +- replacement Indeo 3 decoder +- TLS/SSL and HTTPS protocol support +- AVOptions API rewritten and documented +- most of CODEC_FLAG2_*, some CODEC_FLAG_* and many codec-specific fields in + AVCodecContext deprecated.

From now on we will aim for approximately two major +releases per year. + +Libav 11 is API-, but not ABI-compatible with the previous major release. This +means that the code using our libraries needs to be rebuilt, but no source +changes should be required. Note however, that a number of old APIs remain +deprecated and will be dropped in the near future. All users are strongly +encouraged to update their code as soon as possible. The doc/APIchanges file in +the Libav source tree and the migration guide on the wiki should help with +migration to the new APIs. If those are not sufficient, do not hesitate to +contact us on IRC or through the user mailing list. + +One specific API issue in libavformat deserves mentioning here. When using +libavcodec for decoding or encoding and libavformat for demuxing or muxing, +the standard practice was to use the stream codec context (AVStream.codec) for +actual decoding or encoding. There are multiple problems with this pattern +(the main one is that the decoder/demuxer or encoder/muxer are not necessarily +synchronized and may overwrite each other's state), so it is now strongly +discouraged and will likely be deprecated in the future. Users should instead +allocate a separate decoding or encoding context and populate it from the +demuxing codec context (or the reverse for encoding) with the +avcodec_copy_context() function. + +The main highlights of this release include native Opus, VP7, OpenEXR, and On2 +AVC decoders, HEVC encoding through libx265, new APIs for exporting ReplayGain +and display transformation metadata and countless bug fixes. A large effort was +also expended on internal cleanups which are not very visible to our users, +but should make the codebase cleaner, safer and easier to maintain and extend. +One point worth mentioning is refactoring the large monolithic framework for +architecture-specific codec optimizations into small blocks, which reduces the +size of configurations that selectively enable or disable certain codecs. + +The avserver streaming tool, which has not been maintained for many years and +was mostly broken, was removed from the tree. It was decided that it is a +significant maintenance burden and that we do our users no service by pretending +to support it, while we in fact do not. + +See the Changelog file for a more extensive list of significant changes. + +API changes +----------- + +A number of additional APIs have been introduced and some existing functions +have been deprecated and are scheduled for removal in the next release. +Significant API changes include: + +[libavcodec] ++ Added the avcodec_copy_context() function that must from now on be used for + freeing codec contexts. ++- Added a new VDA hardware acceleration API, since the old one was broken and + not fixable in a compatible way. Deprecated the old VDA API. + +[libavformat] ++ Added support for exporting stream-global (as opposed to per-packet) side + data. This feature is now used by some demuxers to export ReplayGain or + display transformation matrix (aka rotation) or stereoscopic 3D mode. ++ Added an API for live metadata updates through event flags. ++- Changed the way to provide a hint about the desired timebase to muxers. + Previously it was done by setting AVStream.codec.time_base. Now callers + should set AVStream.time_base. + +[libavresample] ++ Added an API for working with AVFrames. + +Please see the file doc/APIchanges for details along with similar +programmer-centric information. diff --git a/doc/avconv.texi b/doc/avconv.texi new file mode 100644 index 0000000..37733bc --- /dev/null +++ b/doc/avconv.texi @@ -0,0 +1,1181 @@ +\input texinfo @c -*- texinfo -*- + +@settitle avconv Documentation +@titlepage +@center @titlefont{avconv Documentation} +@end titlepage + +@top + +@contents + +@chapter Synopsis + +The generic syntax is: + +@example +@c man begin SYNOPSIS +avconv [global options] [[infile options][@option{-i} @var{infile}]]... @{[outfile options] @var{outfile}@}... +@c man end +@end example + +@chapter Description +@c man begin DESCRIPTION + +avconv is a very fast video and audio converter that can also grab from +a live audio/video source. It can also convert between arbitrary sample +rates and resize video on the fly with a high quality polyphase filter. + +avconv reads from an arbitrary number of input "files" (which can be regular +files, pipes, network streams, grabbing devices, etc.), specified by the +@code{-i} option, and writes to an arbitrary number of output "files", which are +specified by a plain output filename. Anything found on the command line which +cannot be interpreted as an option is considered to be an output filename. + +Each input or output file can in principle contain any number of streams of +different types (video/audio/subtitle/attachment/data). Allowed number and/or +types of streams can be limited by the container format. Selecting, which +streams from which inputs go into output, is done either automatically or with +the @code{-map} option (see the Stream selection chapter). + +To refer to input files in options, you must use their indices (0-based). E.g. +the first input file is @code{0}, the second is @code{1} etc. Similarly, streams +within a file are referred to by their indices. E.g. @code{2:3} refers to the +fourth stream in the third input file. See also the Stream specifiers chapter. + +As a general rule, options are applied to the next specified +file. Therefore, order is important, and you can have the same +option on the command line multiple times. Each occurrence is +then applied to the next input or output file. +Exceptions from this rule are the global options (e.g. verbosity level), +which should be specified first. + +Do not mix input and output files -- first specify all input files, then all +output files. Also do not mix options which belong to different files. All +options apply ONLY to the next input or output file and are reset between files. + +@itemize +@item +To set the video bitrate of the output file to 64kbit/s: +@example +avconv -i input.avi -b 64k output.avi +@end example + +@item +To force the frame rate of the output file to 24 fps: +@example +avconv -i input.avi -r 24 output.avi +@end example + +@item +To force the frame rate of the input file (valid for raw formats only) +to 1 fps and the frame rate of the output file to 24 fps: +@example +avconv -r 1 -i input.m2v -r 24 output.avi +@end example +@end itemize + +The format option may be needed for raw input files. + +@c man end DESCRIPTION + +@chapter Detailed description +@c man begin DETAILED DESCRIPTION + +The transcoding process in @command{avconv} for each output can be described by +the following diagram: + +@example + _______ ______________ +| | | | +| input | demuxer | encoded data | decoder +| file | ---------> | packets | -----+ +|_______| |______________| | + v + _________ + | | + | decoded | + | frames | + |_________| + ________ ______________ | +| | | | | +| output | <-------- | encoded data | <----+ +| file | muxer | packets | encoder +|________| |______________| + + +@end example + +@command{avconv} calls the libavformat library (containing demuxers) to read +input files and get packets containing encoded data from them. When there are +multiple input files, @command{avconv} tries to keep them synchronized by +tracking lowest timestamp on any active input stream. + +Encoded packets are then passed to the decoder (unless streamcopy is selected +for the stream, see further for a description). The decoder produces +uncompressed frames (raw video/PCM audio/...) which can be processed further by +filtering (see next section). After filtering the frames are passed to the +encoder, which encodes them and outputs encoded packets again. Finally those are +passed to the muxer, which writes the encoded packets to the output file. + +@section Filtering +Before encoding, @command{avconv} can process raw audio and video frames using +filters from the libavfilter library. Several chained filters form a filter +graph. @command{avconv} distinguishes between two types of filtergraphs - +simple and complex. + +@subsection Simple filtergraphs +Simple filtergraphs are those that have exactly one input and output, both of +the same type. In the above diagram they can be represented by simply inserting +an additional step between decoding and encoding: + +@example + _________ ______________ +| | | | +| decoded | | encoded data | +| frames |\ /| packets | +|_________| \ / |______________| + \ __________ / + simple \ | | / encoder + filtergraph \| filtered |/ + | frames | + |__________| + +@end example + +Simple filtergraphs are configured with the per-stream @option{-filter} option +(with @option{-vf} and @option{-af} aliases for video and audio respectively). +A simple filtergraph for video can look for example like this: + +@example + _______ _____________ _______ ________ +| | | | | | | | +| input | ---> | deinterlace | ---> | scale | ---> | output | +|_______| |_____________| |_______| |________| + +@end example + +Note that some filters change frame properties but not frame contents. E.g. the +@code{fps} filter in the example above changes number of frames, but does not +touch the frame contents. Another example is the @code{setpts} filter, which +only sets timestamps and otherwise passes the frames unchanged. + +@subsection Complex filtergraphs +Complex filtergraphs are those which cannot be described as simply a linear +processing chain applied to one stream. This is the case e.g. when the graph has +more than one input and/or output, or when output stream type is different from +input. They can be represented with the following diagram: + +@example + _________ +| | +| input 0 |\ __________ +|_________| \ | | + \ _________ /| output 0 | + \ | | / |__________| + _________ \| complex | / +| | | |/ +| input 1 |---->| filter |\ +|_________| | | \ __________ + /| graph | \ | | + / | | \| output 1 | + _________ / |_________| |__________| +| | / +| input 2 |/ +|_________| + +@end example + +Complex filtergraphs are configured with the @option{-filter_complex} option. +Note that this option is global, since a complex filtergraph by its nature +cannot be unambiguously associated with a single stream or file. + +A trivial example of a complex filtergraph is the @code{overlay} filter, which +has two video inputs and one video output, containing one video overlaid on top +of the other. Its audio counterpart is the @code{amix} filter. + +@section Stream copy +Stream copy is a mode selected by supplying the @code{copy} parameter to the +@option{-codec} option. It makes @command{avconv} omit the decoding and encoding +step for the specified stream, so it does only demuxing and muxing. It is useful +for changing the container format or modifying container-level metadata. The +diagram above will in this case simplify to this: + +@example + _______ ______________ ________ +| | | | | | +| input | demuxer | encoded data | muxer | output | +| file | ---------> | packets | -------> | file | +|_______| |______________| |________| + +@end example + +Since there is no decoding or encoding, it is very fast and there is no quality +loss. However it might not work in some cases because of many factors. Applying +filters is obviously also impossible, since filters work on uncompressed data. + +@c man end DETAILED DESCRIPTION + +@chapter Stream selection +@c man begin STREAM SELECTION + +By default avconv tries to pick the "best" stream of each type present in input +files and add them to each output file. For video, this means the highest +resolution, for audio the highest channel count. For subtitle it's simply the +first subtitle stream. + +You can disable some of those defaults by using @code{-vn/-an/-sn} options. For +full manual control, use the @code{-map} option, which disables the defaults just +described. + +@c man end STREAM SELECTION + +@chapter Options +@c man begin OPTIONS + +@include avtools-common-opts.texi + +@section Main options + +@table @option + +@item -f @var{fmt} (@emph{input/output}) +Force input or output file format.

They are +raw files, without header. They can be generated by all decent video +decoders. You must specify the size of the image with the @option{-s} option +if avconv cannot guess it. + +@item +You can input from a raw YUV420P file: + +@example +avconv -i /tmp/test.yuv /tmp/out.avi +@end example + +test.yuv is a file containing raw YUV planar data.

'-map +file:index' specifies which input stream is used for each output +stream, in the order of the definition of output streams. + +@item +You can transcode decrypted VOBs: + +@example +avconv -i snatch_1.vob -f avi -c:v mpeg4 -b:v 800k -g 300 -bf 2 -c:a libmp3lame -b:a 128k snatch.avi +@end example + +This is a typical DVD ripping example; the input is a VOB file, the +output an AVI file with MPEG-4 video and MP3 audio. Note that in this +command we use B-frames so the MPEG-4 stream is DivX5 compatible, and +GOP size is 300 which means one intra frame every 10 seconds for 29.97fps +input video. Furthermore, the audio stream is MP3-encoded so you need +to enable LAME support by passing @code{--enable-libmp3lame} to configure. +The mapping is particularly useful for DVD transcoding +to get the desired audio language. + +NOTE: To see the supported input formats, use @code{avconv -formats}. + +@item +You can extract images from a video, or create a video from many images: + +For extracting images from a video: +@example +avconv -i foo.avi -r 1 -s WxH -f image2 foo-%03d.jpeg +@end example + +This will extract one video frame per second from the video and will +output them in files named @file{foo-001.jpeg}, @file{foo-002.jpeg}, +etc. Images will be rescaled to fit the new WxH values. + +If you want to extract just a limited number of frames, you can use the +above command in combination with the -vframes or -t option, or in +combination with -ss to start extracting from a certain point in time. + +For creating a video from many images: +@example +avconv -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi +@end example + +The syntax @code{foo-%03d.jpeg} specifies to use a decimal number +composed of three digits padded with zeroes to express the sequence +number. It is the same syntax supported by the C printf function, but +only formats accepting a normal integer are suitable. + +@item +You can put many streams of the same type in the output: + +@example +avconv -i test1.avi -i test2.avi -map 1:1 -map 1:0 -map 0:1 -map 0:0 -c copy -y test12.nut +@end example + +The resulting output file @file{test12.nut} will contain the first four streams +from the input files in reverse order. + +@item +To force CBR video output: +@example +avconv -i myfile.avi -b 4000k -minrate 4000k -maxrate 4000k -bufsize 1835k out.m2v +@end example + +@item +The four options lmin, lmax, mblmin and mblmax use 'lambda' units, +but you may use the QP2LAMBDA constant to easily convert from 'q' units: +@example +avconv -i src.ext -lmax 21*QP2LAMBDA dst.ext +@end example + +@end itemize +@c man end EXAMPLES + +@include eval.texi +@include decoders.texi +@include encoders.texi +@include demuxers.texi +@include muxers.texi +@include indevs.texi +@include outdevs.texi +@include protocols.texi +@include bitstream_filters.texi +@include filters.texi +@include metadata.texi + +@ignore + +@setfilename avconv +@settitle avconv video converter + +@c man begin SEEALSO +avplay(1), avprobe(1) and the Libav HTML documentation +@c man end + +@c man begin AUTHORS +The Libav developers +@c man end + +@end ignore + +@bye diff --git a/doc/avplay.texi b/doc/avplay.texi new file mode 100644 index 0000000..71981f6 --- /dev/null +++ b/doc/avplay.texi @@ -0,0 +1,184 @@ +\input texinfo @c -*- texinfo -*- + +@settitle avplay Documentation +@titlepage +@center @titlefont{avplay Documentation} +@end titlepage + +@top + +@contents + +@chapter Synopsis + +@example +@c man begin SYNOPSIS +avplay [options] @file{input_file} +@c man end +@end example + +@chapter Description +@c man begin DESCRIPTION + +AVplay is a very simple and portable media player using the Libav +libraries and the SDL library.

Especially watch out for: + +@itemize @bullet +@item +mixing statements and declarations; + +@item +@samp{long long} (use @samp{int64_t} instead); + +@item +@samp{__attribute__} not protected by @samp{#ifdef __GNUC__} or similar; + +@item +GCC statement expressions (@samp{(x = (@{ int y = 4; y; @})}). +@end itemize + +@subsection Naming conventions +All names should be composed with underscores (_), not CamelCase. For example, +@samp{avfilter_get_video_buffer} is an acceptable function name and +@samp{AVFilterGetVideo} is not. The only exception are structure +names; they should always be CamelCase. + +There are the following conventions for naming variables and functions: + +@itemize @bullet +@item +For local variables no prefix is required. + +@item +For file-scope variables and functions declared as @code{static}, no prefix +is required. + +@item +For variables and functions visible outside of file scope, but only used +internally by a library, an @code{ff_} prefix should be used, +e.g. @samp{ff_w64_demuxer}. + +@item +For variables and functions visible outside of file scope, used internally +across multiple libraries, use @code{avpriv_} as prefix, for example, +@samp{avpriv_aac_parse_header}. + +@item +For externally visible symbols, each library has its own prefix. Check +the existing code and choose names accordingly. +@end itemize + +Furthermore, name space reserved for the system should not be invaded. +Identifiers ending in @code{_t} are reserved by +@url{http://pubs.opengroup.org/onlinepubs/007904975/functions/xsh_chap02_02.html#tag_02_02_02, POSIX}. +Also avoid names starting with @code{__} or @code{_} followed by an uppercase +letter as they are reserved by the C standard. Names starting with @code{_} +are reserved at the file level and may not be used for externally visible +symbols. If in doubt, just avoid names starting with @code{_} altogether. + +@subsection Miscellaneous conventions + +@itemize @bullet +@item +fprintf and printf are forbidden in libavformat and libavcodec, +please use av_log() instead. + +@item +Casts should be used only when necessary. Unneeded parentheses +should also be avoided if they don't make the code easier to understand. +@end itemize + +@subsection Editor configuration +In order to configure Vim to follow Libav formatting conventions, paste +the following snippet into your @file{.vimrc}: +@example +" Indentation rules for Libav: 4 spaces, no tabs. +set expandtab +set shiftwidth=4 +set softtabstop=4 +set cindent +set cinoptions=(0 +" Allow tabs in Makefiles. +autocmd FileType make,automake set noexpandtab shiftwidth=8 softtabstop=8 +" Trailing whitespace and tabs are forbidden, so highlight them. +highlight ForbiddenWhitespace ctermbg=red guibg=red +match ForbiddenWhitespace /\s\+$\|\t/ +" Do not highlight spaces at the end of line while typing on that line. +autocmd InsertEnter * match ForbiddenWhitespace /\t\|\s\+\%#\@@100k to mails but rather provide a +URL, you can upload to ftp://upload.libav.org + +@item +Did you provide a verbose summary about what the patch does change? + +@item +Did you provide a verbose explanation why it changes things like it does? + +@item +Did you provide a verbose summary of the user visible advantages and +disadvantages if the patch is applied? + +@item +Did you provide an example so we can verify the new feature added by the +patch easily? + +@item +If you added a new file, did you insert a license header?

Especially memory allocation functions like @code{malloc()} +are notoriously left unchecked, which is a serious problem. +@end enumerate + +@section Patch review process + +All patches posted to the +@uref{https://lists.libav.org/mailman/listinfo/libav-devel, libav-devel} +mailing list will be reviewed, unless they contain a +clear note that the patch is not for the git master branch. +Reviews and comments will be posted as replies to the patch on the +mailing list. The patch submitter then has to take care of every comment, +that can be by resubmitting a changed patch or by discussion. Resubmitted +patches will themselves be reviewed like any other patch. If at some point +a patch passes review with no comments then it is approved, that can for +simple and small patches happen immediately while large patches will generally +have to be changed and reviewed many times before they are approved. +After a patch is approved it will be committed to the repository. + +We will review all submitted patches, but sometimes we are quite busy so +especially for large patches this can take several weeks. + +When resubmitting patches, if their size grew or during the review different +issues arisen please split the patch so each issue has a specific patch. + +@anchor{Regression Tests} +@section Regression Tests + +Before submitting a patch (or committing to the repository), you should at +least make sure that it does not break anything. + +If the code changed has already a test present in FATE you should run it, +otherwise it is advised to add it. + +Improvements to codec or demuxer might change the FATE results. Make sure +to commit the update reference with the change and to explain in the comment +why the expected result changed. + +Please refer to @url{fate.html}. + +@subsection Visualizing Test Coverage + +The Libav build system allows visualizing the test coverage in an easy +manner with the coverage tools @code{gcov}/@code{lcov}. This involves +the following steps: + +@enumerate +@item + Configure to compile with instrumentation enabled: + @code{configure --toolchain=gcov}. + +@item + Run your test case, either manually or via FATE. This can be either + the full FATE regression suite, or any arbitrary invocation of any + front-end tool provided by Libav, in any combination. + +@item + Run @code{make lcov} to generate coverage data in HTML format. + +@item + View @code{lcov/index.html} in your preferred HTML viewer. +@end enumerate + +You can use the command @code{make lcov-reset} to reset the coverage +measurements. You will need to rerun @code{make lcov} after running a +new test. + +@subsection Using Valgrind + +The configure script provides a shortcut for using valgrind to spot bugs +related to memory handling. Just add the option +@code{--toolchain=valgrind-memcheck} or @code{--toolchain=valgrind-massif} +to your configure line, and reasonable defaults will be set for running +FATE under the supervision of either the @strong{memcheck} or the +@strong{massif} tool of the valgrind suite. + +In case you need finer control over how valgrind is invoked, use the +@code{--target-exec='valgrind } option in +your configure line instead. + +@anchor{Release process} +@section Release process + +Libav maintains a set of @strong{release branches}, which are the +recommended deliverable for system integrators and distributors (such as +Linux distributions, etc.). At irregular times, a @strong{release +manager} prepares, tests and publishes tarballs on the +@url{http://libav.org} website. + +There are two kinds of releases: + +@enumerate +@item +@strong{Major releases} always include the latest and greatest +features and functionality. + +@item +@strong{Point releases} are cut from @strong{release} branches, +which are named @code{release/X}, with @code{X} being the release +version number. +@end enumerate + +Note that we promise to our users that shared libraries from any Libav +release never break programs that have been @strong{compiled} against +previous versions of @strong{the same release series} in any case! + +However, from time to time, we do make API changes that require adaptations +in applications. Such changes are only allowed in (new) major releases and +require further steps such as bumping library version numbers and/or +adjustments to the symbol versioning file. Please discuss such changes +on the @strong{libav-devel} mailing list in time to allow forward planning. + +@anchor{Criteria for Point Releases} +@subsection Criteria for Point Releases + +Changes that match the following criteria are valid candidates for +inclusion into a point release: + +@enumerate +@item +Fixes a security issue, preferably identified by a @strong{CVE +number} issued by @url{http://cve.mitre.org/}. + +@item +Fixes a documented bug in @url{http://bugzilla.libav.org}. + +@item +Improves the included documentation. + +@item +Retains both source code and binary compatibility with previous +point releases of the same release branch. +@end enumerate + +The order for checking the rules is (1 OR 2 OR 3) AND 4. + +All Libav developers are welcome to nominate commits that they push to +@code{master} by mailing the @strong{libav-stable} mailing list. The +easiest way to do so is to include @code{CC: libav-stable@@libav.org} in +the commit message. + + +@subsection Release Checklist + +The release process involves the following steps: + +@enumerate +@item +Ensure that the @file{RELEASE} file contains the version number for +the upcoming release. + +@item +File a release tracking bug in @url{http://bugzilla.libav.org}. Make +sure that the bug has an alias named @code{ReleaseX.Y} for the +@code{X.Y} release. + +@item +Announce the intent to do a release to the mailing list. + +@item +Reassign unresolved blocking bugs from previous release +tracking bugs to the new bug. + +@item +Review patch nominations that reach the @strong{libav-stable} +mailing list, and push patches that fulfill the stable release +criteria to the release branch. + +@item +Ensure that the FATE regression suite still passes in the release +branch on at least @strong{i386} and @strong{amd64} +(cf. @ref{Regression Tests}). + +@item +Prepare the release tarballs in @code{xz} and @code{gz} formats, and +supplementing files that contain @code{md5} and @code{sha1} +checksums. + +@item +Publish the tarballs at @url{http://libav.org/releases}. Create and +push an annotated tag in the form @code{vX}, with @code{X} +containing the version number. + +@item +Build the tarballs with the Windows binaries, and publish them at +@url{http://win32.libav.org/releases}. + +@item +Propose and send a patch to the @strong{libav-devel} mailing list +with a news entry for the website. + +@item +Publish the news entry. + +@item +Send announcement to the mailing list. +@end enumerate + +@bye diff --git a/doc/doxy-wrapper.sh b/doc/doxy-wrapper.sh new file mode 100755 index 0000000..d38dd0b --- /dev/null +++ b/doc/doxy-wrapper.sh @@ -0,0 +1,15 @@ +#!/bin/sh + +SRC_PATH="${1}" +DOXYFILE="${2}" + +shift 2 + +doxygen - < li > a { + display: block;

Libav development is +driven by the tasks that are important to the individual developers. +If there is a feature that is important to you, the best way to get +it implemented is to undertake the task yourself or sponsor a developer. + +@section Libav does not support codec XXX. Can you include a Windows DLL loader to support it? + +No. Windows DLLs are not portable, bloated and often slow. +Moreover Libav strives to support all codecs natively. +A DLL loader is not conducive to that goal. + +@section I cannot read this file although this format seems to be supported by avconv. + +Even if avconv can read the container format, it may not support all its +codecs. Please consult the supported codec list in the avconv +documentation. + +@section Which codecs are supported by Windows? + +Windows does not support standard formats like MPEG very well, unless you +install some additional codecs. + +The following list of video codecs should work on most Windows systems: +@table @option +@item msmpeg4v2 +.avi/.asf +@item msmpeg4 +.asf only +@item wmv1 +.asf only +@item wmv2 +.asf only +@item mpeg4 +Only if you have some MPEG-4 codec like ffdshow or Xvid installed. +@item mpeg1video +.mpg only +@end table +Note, ASF files often have .wmv or .wma extensions in Windows.

The command, using the bourne +shell syntax, symbolically links all files in the current directory +that match @code{*jpg} to the @file{/tmp} directory in the sequence of +@file{img001.jpg}, @file{img002.jpg} and so on. + +@example + x=1; for i in *jpg; do counter=$(printf %03d $x); ln -s "$i" /tmp/img"$counter".jpg; x=$(($x+1)); done +@end example + +If you want to sequence them by oldest modified first, substitute +@code{$(ls -r -t *jpg)} in place of @code{*jpg}. + +Then run: + +@example + avconv -f image2 -i /tmp/img%03d.jpg /tmp/a.mpg +@end example + +The same logic is used for any image format that avconv reads. + +@section How do I encode movie to single pictures? + +Use: + +@example + avconv -i movie.mpg movie%d.jpg +@end example + +The @file{movie.mpg} used as input will be converted to +@file{movie1.jpg}, @file{movie2.jpg}, etc... + +Instead of relying on file format self-recognition, you may also use +@table @option +@item -c:v ppm +@item -c:v png +@item -c:v mjpeg +@end table +to force the encoding. + +Applying that to the previous example: +@example + avconv -i movie.mpg -f image2 -c:v mjpeg menu%d.jpg +@end example + +Beware that there is no "jpeg" codec. Use "mjpeg" instead. + +@section Why do I see a slight quality degradation with multithreaded MPEG* encoding? + +For multithreaded MPEG* encoding, the encoded slices must be independent, +otherwise thread n would practically have to wait for n-1 to finish, so it's +quite logical that there is a small reduction of quality. This is not a bug. + +@section How can I read from the standard input or write to the standard output? + +Use @file{-} as file name. + +@section -f jpeg doesn't work. + +Try '-f image2 test%d.jpg'. + +@section Why can I not change the framerate? + +Some codecs, like MPEG-1/2, only allow a small number of fixed framerates. +Choose a different codec with the -c:v command line option. + +@section How do I encode Xvid or DivX video with avconv? + +Both Xvid and DivX (version 4+) are implementations of the ISO MPEG-4 +standard (note that there are many other coding formats that use this +same standard). Thus, use '-c:v mpeg4' to encode in these formats. The +default fourcc stored in an MPEG-4-coded file will be 'FMP4'. If you want +a different fourcc, use the '-vtag' option. E.g., '-vtag xvid' will +force the fourcc 'xvid' to be stored as the video fourcc rather than the +default. + +@section Which are good parameters for encoding high quality MPEG-4? + +'-mbd rd -flags +mv4+aic -trellis 2 -cmp 2 -subcmp 2 -g 300 -pass 1/2', +things to try: '-bf 2', '-flags qprd', '-flags mv0', '-flags skiprd'. + +@section Which are good parameters for encoding high quality MPEG-1/MPEG-2? + +'-mbd rd -trellis 2 -cmp 2 -subcmp 2 -g 100 -pass 1/2' +but beware the '-g 100' might cause problems with some decoders. +Things to try: '-bf 2', '-flags qprd', '-flags mv0', '-flags skiprd. + +@section Interlaced video looks very bad when encoded with avconv, what is wrong? + +You should use '-flags +ilme+ildct' and maybe '-flags +alt' for interlaced +material, and try '-top 0/1' if the result looks really messed-up. + +@section How can I read DirectShow files? + +If you have built Libav with @code{./configure --enable-avisynth} +(only possible on MinGW/Cygwin platforms), +then you may use any file that DirectShow can read as input. + +Just create an "input.avs" text file with this single line ... +@example + DirectShowSource("C:\path to your file\yourfile.asf") +@end example +... and then feed that text file to avconv: +@example + avconv -i input.avs +@end example + +For ANY other help on AviSynth, please visit the +@uref{http://www.avisynth.org/, AviSynth homepage}. + +@section How can I join video files? + +A few multimedia containers (MPEG-1, MPEG-2 PS, DV) allow to join video files by +merely concatenating them. + +Hence you may concatenate your multimedia files by first transcoding them to +these privileged formats, then using the humble @code{cat} command (or the +equally humble @code{copy} under Windows), and finally transcoding back to your +format of choice. + +@example +avconv -i input1.avi intermediate1.mpg +avconv -i input2.avi intermediate2.mpg +cat intermediate1.mpg intermediate2.mpg > intermediate_all.mpg +avconv -i intermediate_all.mpg output.avi +@end example + +Notice that you should set a reasonably high bitrate for your intermediate and +output files, if you want to preserve video quality. + +Also notice that you may avoid the huge intermediate files by taking advantage +of named pipes, should your platform support it: + +@example +mkfifo intermediate1.mpg +mkfifo intermediate2.mpg +avconv -i input1.avi -y intermediate1.mpg < /dev/null & +avconv -i input2.avi -y intermediate2.mpg < /dev/null & +cat intermediate1.mpg intermediate2.mpg |\ +avconv -f mpeg -i - -c:v mpeg4 -acodec libmp3lame output.avi +@end example + +Similarly, the yuv4mpegpipe format, and the raw video, raw audio codecs also +allow concatenation, and the transcoding step is almost lossless. +When using multiple yuv4mpegpipe(s), the first line needs to be discarded +from all but the first stream. This can be accomplished by piping through +@code{tail} as seen below. Note that when piping through @code{tail} you +must use command grouping, @code{@{ ;@}}, to background properly. + +For example, let's say we want to join two FLV files into an output.flv file: + +@example +mkfifo temp1.a +mkfifo temp1.v +mkfifo temp2.a +mkfifo temp2.v +mkfifo all.a +mkfifo all.v +avconv -i input1.flv -vn -f u16le -acodec pcm_s16le -ac 2 -ar 44100 - > temp1.a < /dev/null & +avconv -i input2.flv -vn -f u16le -acodec pcm_s16le -ac 2 -ar 44100 - > temp2.a < /dev/null & +avconv -i input1.flv -an -f yuv4mpegpipe - > temp1.v < /dev/null & +@{ avconv -i input2.flv -an -f yuv4mpegpipe - < /dev/null | tail -n +2 > temp2.v ; @} & +cat temp1.a temp2.a > all.a & +cat temp1.v temp2.v > all.v & +avconv -f u16le -acodec pcm_s16le -ac 2 -ar 44100 -i all.a \ + -f yuv4mpegpipe -i all.v \ + -y output.flv +rm temp[12].[av] all.[av] +@end example + +@section -profile option fails when encoding H.264 video with AAC audio + +@command{avconv} prints an error like + +@example +Undefined constant or missing '(' in 'baseline' +Unable to parse option value "baseline" +Error setting option profile to value baseline. +@end example + +Short answer: write @option{-profile:v} instead of @option{-profile}. + +Long answer: this happens because the @option{-profile} option can apply to both +video and audio. Specifically the AAC encoder also defines some profiles, none +of which are named @var{baseline}. + +The solution is to apply the @option{-profile} option to the video stream only +by using @url{http://libav.org/avconv.html#Stream-specifiers-1, Stream specifiers}. +Appending @code{:v} to it will do exactly that. + +@chapter Development + +@section Are there examples illustrating how to use the Libav libraries, particularly libavcodec and libavformat? + +Yes. Read the Developers Guide of the Libav documentation. Alternatively, +examine the source code for one of the many open source projects that +already incorporate Libav at (@url{projects.html}). + +@section Can you support my C compiler XXX? + +It depends. If your compiler is C99-compliant, then patches to support +it are likely to be welcome if they do not pollute the source code +with @code{#ifdef}s related to the compiler. + +@section Is Microsoft Visual C++ supported? + +Yes. Please see the @uref{platform.html, Microsoft Visual C++} +section in the Libav documentation. + +@section Can you add automake, libtool or autoconf support? + +No. These tools are too bloated and they complicate the build. + +@section Why not rewrite Libav in object-oriented C++? + +Libav is already organized in a highly modular manner and does not need to +be rewritten in a formal object language. Further, many of the developers +favor straight C; it works for them. For more arguments on this matter, +read @uref{http://www.tux.org/lkml/#s15, "Programming Religion"}. + +@section I do not like the LGPL, can I contribute code under the GPL instead? + +Yes, as long as the code is optional and can easily and cleanly be placed +under #if CONFIG_GPL without breaking anything. So for example a new codec +or filter would be OK under GPL while a bug fix to LGPL code would not. + +@section I'm using Libav from within my C++ application but the linker complains about missing symbols which seem to be available. + +Libav is a pure C project, so to use the libraries within your C++ application +you need to explicitly state that you are using a C library.

It can contain +cycles, and there can be multiple links between a pair of +filters. Each link has one input pad on one side connecting it to one +filter from which it takes its input, and one output pad on the other +side connecting it to one filter accepting its output. + +Each filter in a filtergraph is an instance of a filter class +registered in the application, which defines the features and the +number of input and output pads of the filter. + +A filter with no input pads is called a "source", and a filter with no +output pads is called a "sink". + +@anchor{Filtergraph syntax} +@section Filtergraph syntax + +A filtergraph has a textual representation, which is +recognized by the @option{-filter}/@option{-vf} and @option{-filter_complex} +options in @command{avconv} and @option{-vf} in @command{avplay}, and by the +@code{avfilter_graph_parse()}/@code{avfilter_graph_parse2()} functions defined in +@file{libavfilter/avfilter.h}. + +A filterchain consists of a sequence of connected filters, each one +connected to the previous one in the sequence. A filterchain is +represented by a list of ","-separated filter descriptions. + +A filtergraph consists of a sequence of filterchains. A sequence of +filterchains is represented by a list of ";"-separated filterchain +descriptions. + +A filter is represented by a string of the form: +[@var{in_link_1}]...[@var{in_link_N}]@var{filter_name}=@var{arguments}[@var{out_link_1}]...[@var{out_link_M}] + +@var{filter_name} is the name of the filter class of which the +described filter is an instance of, and has to be the name of one of +the filter classes registered in the program. +The name of the filter class is optionally followed by a string +"=@var{arguments}". + +@var{arguments} is a string which contains the parameters used to +initialize the filter instance. It may have one of two forms: +@itemize + +@item +A ':'-separated list of @var{key=value} pairs. + +@item +A ':'-separated list of @var{value}. In this case, the keys are assumed to be +the option names in the order they are declared. E.g. the @code{fade} filter +declares three options in this order -- @option{type}, @option{start_frame} and +@option{nb_frames}. Then the parameter list @var{in:0:30} means that the value +@var{in} is assigned to the option @option{type}, @var{0} to +@option{start_frame} and @var{30} to @option{nb_frames}. + +@end itemize + +If the option value itself is a list of items (e.g. the @code{format} filter +takes a list of pixel formats), the items in the list are usually separated by +'|'. + +The list of arguments can be quoted using the character "'" as initial +and ending mark, and the character '\' for escaping the characters +within the quoted text; otherwise the argument string is considered +terminated when the next special character (belonging to the set +"[]=;,") is encountered. + +The name and arguments of the filter are optionally preceded and +followed by a list of link labels. +A link label allows to name a link and associate it to a filter output +or input pad. The preceding labels @var{in_link_1} +... @var{in_link_N}, are associated to the filter input pads, +the following labels @var{out_link_1} ... @var{out_link_M}, are +associated to the output pads. + +When two link labels with the same name are found in the +filtergraph, a link between the corresponding input and output pad is +created. + +If an output pad is not labelled, it is linked by default to the first +unlabelled input pad of the next filter in the filterchain. +For example in the filterchain +@example +nullsrc, split[L1], [L2]overlay, nullsink +@end example +the split filter instance has two output pads, and the overlay filter +instance two input pads. The first output pad of split is labelled +"L1", the first input pad of overlay is labelled "L2", and the second +output pad of split is linked to the second input pad of overlay, +which are both unlabelled. + +In a complete filterchain all the unlabelled filter input and output +pads must be connected. A filtergraph is considered valid if all the +filter input and output pads of all the filterchains are connected. + +Libavfilter will automatically insert @ref{scale} filters where format +conversion is required. It is possible to specify swscale flags +for those automatically inserted scalers by prepending +@code{sws_flags=@var{flags};} +to the filtergraph description. + +Here is a BNF description of the filtergraph syntax: +@example +@var{NAME} ::= sequence of alphanumeric characters and '_' +@var{LINKLABEL} ::= "[" @var{NAME} "]" +@var{LINKLABELS} ::= @var{LINKLABEL} [@var{LINKLABELS}] +@var{FILTER_ARGUMENTS} ::= sequence of chars (possibly quoted) +@var{FILTER} ::= [@var{LINKLABELS}] @var{NAME} ["=" @var{FILTER_ARGUMENTS}] [@var{LINKLABELS}] +@var{FILTERCHAIN} ::= @var{FILTER} [,@var{FILTERCHAIN}] +@var{FILTERGRAPH} ::= [sws_flags=@var{flags};] @var{FILTERCHAIN} [;@var{FILTERGRAPH}] +@end example + +@c man end FILTERGRAPH DESCRIPTION + +@chapter Audio Filters +@c man begin AUDIO FILTERS + +When you configure your Libav build, you can disable any of the +existing filters using --disable-filters. +The configure output will show the audio filters included in your +build. + +Below is a description of the currently available audio filters. + +@section aformat + +Convert the input audio to one of the specified formats.

Disabled +by default. When disabled, time gaps are covered with silence. + +@item min_delta +The minimum difference between timestamps and audio data (in seconds) to trigger +adding/dropping samples. The default value is 0.1. If you get an imperfect +sync with this filter, try setting this parameter to 0. + +@item max_comp +The maximum compensation in samples per second. Only relevant with compensate=1. +The default value is 500. + +@item first_pts +Assume that the first PTS should be this value. The time base is 1 / sample +rate. This allows for padding/trimming at the start of the stream. By default, +no assumption is made about the first frame's expected PTS, so no padding or +trimming is done. For example, this could be set to 0 to pad the beginning with +silence if an audio stream starts after the video stream or to trim any samples +with a negative PTS due to encoder delay. + +@end table + +@section atrim +Trim the input so that the output contains one continuous subpart of the input. + +It accepts the following parameters: +@table @option +@item start +Timestamp (in seconds) of the start of the section to keep.

So start/end_pts and start/end_sample will +give different results when the timestamps are wrong, inexact or do not start at +zero. Also note that this filter does not modify the timestamps. If you wish +to have the output timestamps start at zero, insert the asetpts filter after the +atrim filter. + +If multiple start or end options are set, this filter tries to be greedy and +keep all samples that match at least one of the specified constraints. To keep +only the part that matches all the constraints at once, chain multiple atrim +filters. + +The defaults are such that all the input is kept.

references on a set of useful git +commands. You should always use the extensive and detailed documentation +provided directly by git: + +@example +git --help +man git +@end example + +shows you the available subcommands, + +@example +git --help +man git- +@end example + +shows information about the subcommand . + +Additional information could be found on the +@url{http://gitref.org, Git Reference} website + +For more information about the Git project, visit the + +@url{http://git-scm.com/, Git website} + +Consult these resources whenever you have problems, they are quite exhaustive. + +What follows now is a basic introduction to Git and some Libav-specific +guidelines to ease the contribution to the project + +@chapter Basics Usage + +@section Get GIT + +You can get git from @url{http://git-scm.com/} +Most distribution and operating system provide a package for it. + + +@section Cloning the source tree + +@example +git clone git://git.libav.org/libav.git +@end example + +This will put the Libav sources into the directory @var{}. + +@example +git clone git@@git.libav.org:libav.git +@end example + +This will put the Libav sources into the directory @var{} and let +you push back your changes to the remote repository. + +Make sure that you do not have Windows line endings in your checkouts, +otherwise you may experience spurious compilation failures. One way to +achieve this is to run + +@example +git config --global core.autocrlf false +@end example + + +@section Updating the source tree to the latest revision + +@example +git pull (--rebase) +@end example + +pulls in the latest changes from the tracked branch. The tracked branch +can be remote. By default the master branch tracks the branch master in +the remote origin. + +@float IMPORTANT +Since merge commits are forbidden @command{--rebase} (see below) is recommended. +@end float + +@section Rebasing your local branches + +@example +git pull --rebase +@end example + +fetches the changes from the main repository and replays your local commits +over it.

This list tries to be exhaustive. In case you are just +pushing a typo in a comment, some of the steps may be unnecessary. +Apply your common sense, but if in doubt, err on the side of caution. + +First make sure your Git repository is on a branch that is a direct +descendant of the Libav master branch, which is the only one from which +pushing to Libav is possible. Then run the following command: + +@itemize +@item @command{git log --patch --stat origin/master..} + +to make sure that only the commits you want to push are pending, that +the log messages of the commits are correct and descriptive and contain +no cruft from @command{git am} and to doublecheck that the commits you +want to push really only contain the changes they are supposed to contain. + +@item @command{git status} + +to ensure no local changes still need to be committed and that no local +changes may have thrown off the results of your testing. +@end itemize + +Next let the code pass through a full run of our testsuite. Before you do, +the command @command{make fate-rsync} will update the test samples. Changes +to the samples set are not very common and commits depending on samples +changes are delayed for at least 24 hours to allow the new samples to +propagate, so updating it once per day is sufficient. Now execute + +@itemize +@item @command{make distclean} +@item @command{/path/to/libav/configure} +@item @command{make check} +@end itemize + +While the test suite covers a wide range of possible problems, it is not +a panacea. Do not hesitate to perform any other tests necessary to convince +yourself that the changes you are about to push actually work as expected. + +Also note that every single commit should pass the test suite, not just +the result of a series of patches. So if you have a series of commits +to push, run the test suite on every single commit. + +Give other developers a reasonable amount of time to look at and review +patches before you push them. Not everybody is online 24/7, but may wish +to look at and comment on a patch nonetheless. The time you leave depends +on the urgency and complexity of the patch. Use your common sense to pick +a timeframe that allows everybody that you think may wish to comment +and/or should comment on the change an opportunity to see it. + +Finally, after pushing, mark all patches as committed on +@url{http://patches.libav.org/,patchwork}. +Sometimes this is not automatically done when a patch has been +slightly modified from the version on the mailing list. +Also update previous incarnations of the patches you push so that +patchwork is not cluttered with cruft. + + +@chapter Server Issues + +Contact the project admins @email{git@@libav.org} if you have technical +problems with the GIT server. diff --git a/doc/git-howto.txt b/doc/git-howto.txt new file mode 100644 index 0000000..036b567 --- /dev/null +++ b/doc/git-howto.txt @@ -0,0 +1,272 @@ + +About Git write access: +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Before everything else, you should know how to use GIT properly. +Luckily Git comes with excellent documentation. + + git --help + man git + +shows you the available subcommands, + + git --help + man git- + +shows information about the subcommand . + +The most comprehensive manual is the website Git Reference + +http://gitref.org/ + +For more information about the Git project, visit + +http://git-scm.com/ + +Consult these resources whenever you have problems, they are quite exhaustive. + +You do not need a special username or password. +All you need is to provide a ssh public key to the Git server admin. + +What follows now is a basic introduction to Git and some Libav-specific +guidelines.

If the available space does not suffice, muxing will fail.

Normally, a MOV/MP4 +file has all the metadata about all packets stored in one location +(written at the end of the file, it can be moved to the start for +better playback using the @command{qt-faststart} tool). A fragmented +file consists of a number of fragments, where packets and metadata +about these packets are stored together. Writing a fragmented +file has the advantage that the file is decodable even if the +writing is interrupted (while a normal MOV/MP4 is undecodable if +it is not properly finished), and it requires less memory when writing +very long files (since writing normal MOV/MP4 files stores info about +every single packet in memory until the file is closed). The downside +is that it is less compatible with other applications. + +Fragmentation is enabled by setting one of the AVOptions that define +how to cut the file into fragments: + +@table @option +@item -movflags frag_keyframe +Start a new fragment at each video keyframe. +@item -frag_duration @var{duration} +Create fragments that are @var{duration} microseconds long. +@item -frag_size @var{size} +Create fragments that contain up to @var{size} bytes of payload data. +@item -movflags frag_custom +Allow the caller to manually choose when to cut fragments, by +calling @code{av_write_frame(ctx, NULL)} to write a fragment with +the packets written so far. (This is only useful with other +applications integrating libavformat, not from @command{avconv}.) +@item -min_frag_duration @var{duration} +Don't create fragments that are shorter than @var{duration} microseconds long. +@end table + +If more than one condition is specified, fragments are cut when +one of the specified conditions is fulfilled. The exception to this is +@code{-min_frag_duration}, which has to be fulfilled for any of the other +conditions to apply. + +Additionally, the way the output file is written can be adjusted +through a few other options: + +@table @option +@item -movflags empty_moov +Write an initial moov atom directly at the start of the file, without +describing any samples in it. Generally, an mdat/moov pair is written +at the start of the file, as a normal MOV/MP4 file, containing only +a short portion of the file. With this option set, there is no initial +mdat atom, and the moov atom only describes the tracks but has +a zero duration. + +Files written with this option set do not work in QuickTime. +This option is implicitly set when writing ismv (Smooth Streaming) files. +@item -movflags separate_moof +Write a separate moof (movie fragment) atom for each track. Normally, +packets for all tracks are written in a moof atom (which is slightly +more efficient), but with this option set, the muxer writes one moof/mdat +pair for each track, making it easier to separate tracks. + +This option is implicitly set when writing ismv (Smooth Streaming) files. +@item -movflags faststart +Run a second pass moving the index (moov atom) to the beginning of the file. +This operation can take a while, and will not work in various situations such +as fragmented output, thus it is not enabled by default. +@item -movflags disable_chpl +Disable Nero chapter markers (chpl atom). Normally, both Nero chapters +and a QuickTime chapter track are written to the file. With this option +set, only the QuickTime chapter track will be written. Nero chapters can +cause failures when the file is reprocessed with certain tagging programs. +@end table + +Smooth Streaming content can be pushed in real time to a publishing +point on IIS with this muxer. Example: +@example +avconv -re @var{} -movflags isml+frag_keyframe -f ismv http://server/publishingpoint.isml/Streams(Encoder1) +@end example + +@section mp3 + +The MP3 muxer writes a raw MP3 stream with an ID3v2 header at the beginning and +optionally an ID3v1 tag at the end. ID3v2.3 and ID3v2.4 are supported, the +@code{id3v2_version} option controls which one is used. Setting +@code{id3v2_version} to 0 will disable the ID3v2 header completely. The legacy +ID3v1 tag is not written by default, but may be enabled with the +@code{write_id3v1} option. + +The muxer may also write a Xing frame at the beginning, which contains the +number of frames in the file. It is useful for computing duration of VBR files. +The Xing frame is written if the output stream is seekable and if the +@code{write_xing} option is set to 1 (the default). + +The muxer supports writing ID3v2 attached pictures (APIC frames). The pictures +are supplied to the muxer in form of a video stream with a single packet. There +can be any number of those streams, each will correspond to a single APIC frame. +The stream metadata tags @var{title} and @var{comment} map to APIC +@var{description} and @var{picture type} respectively. See +@url{http://id3.org/id3v2.4.0-frames} for allowed picture types. + +Note that the APIC frames must be written at the beginning, so the muxer will +buffer the audio frames until it gets all the pictures.

It is recommended to look at older +revisions of the interesting files (web frontends for the various Libav +branches are listed at http://libav.org/download.html). +Alternatively, look into the other architecture-specific versions in +the x86/, ppc/, alpha/ subdirectories. Even if you don't exactly +comprehend the instructions, it could help understanding the functions +and how they can be optimized. + +NOTE: If you still don't understand some function, ask at our mailing list!!! +(https://lists.libav.org/mailman/listinfo/libav-devel) + + +When is an optimization justified? +---------------------------------- +Normally, clean and simple optimizations for widely used codecs are +justified even if they only achieve an overall speedup of 0.1%. These +speedups accumulate and can make a big difference after awhile. Also, if +none of the following factors get worse due to an optimization -- speed, +binary code size, source size, source readability -- and at least one +factor improves, then an optimization is always a good idea even if the +overall gain is less than 0.1%.

This means both +general x86 registers (e.g. eax) as well as XMM registers. This last one is +particularly important on Win64, where xmm6-15 are callee-save, and not +restoring their contents leads to undefined results. In external asm (e.g. +yasm), you do this by using: +cglobal functon_name, num_args, num_regs, num_xmm_regs +In inline asm, you specify clobbered registers at the end of your asm: +__asm__(".." ::: "%eax"). +If gcc is not set to support sse (-msse) it will not accept xmm registers +in the clobber list. For that we use two macros to declare the clobbers. +XMM_CLOBBERS should be used when there are other clobbers, for example: +__asm__(".." ::: XMM_CLOBBERS("xmm0",) "eax"); +and XMM_CLOBBERS_ONLY should be used when the only clobbers are xmm registers: +__asm__(".." :: XMM_CLOBBERS_ONLY("xmm0")); + +Do not expect a compiler to maintain values in your registers between separate +(inline) asm code blocks. It is not required to. For example, this is bad: +__asm__("movdqa %0, %%xmm7" : src); +/* do something */ +__asm__("movdqa %%xmm7, %1" : dst); +- first of all, you're assuming that the compiler will not use xmm7 in + between the two asm blocks. It probably won't when you test it, but it's + a poor assumption that will break at some point for some --cpu compiler flag +- secondly, you didn't mark xmm7 as clobbered. If you did, the compiler would + have restored the original value of xmm7 after the first asm block, thus + rendering the combination of the two blocks of code invalid +Code that depends on data in registries being untouched, should be written as +a single __asm__() statement. Ideally, a single function contains only one +__asm__() block. + +Use external asm (nasm/yasm) or inline asm (__asm__()), do not use intrinsics. +The latter requires a good optimizing compiler which gcc is not. + +Inline asm vs. external asm +--------------------------- +Both inline asm (__asm__("..") in a .c file, handled by a compiler such as gcc) +and external asm (.s or .asm files, handled by an assembler such as yasm/nasm) +are accepted in Libav. Which one to use differs per specific case. + +- if your code is intended to be inlined in a C function, inline asm is always + better, because external asm cannot be inlined +- if your code calls external functions, yasm is always better +- if your code takes huge and complex structs as function arguments (e.g. + MpegEncContext; note that this is not ideal and is discouraged if there + are alternatives), then inline asm is always better, because predicting + member offsets in complex structs is almost impossible. It's safest to let + the compiler take care of that +- in many cases, both can be used and it just depends on the preference of the + person writing the asm. For new asm, the choice is up to you. For existing + asm, you'll likely want to maintain whatever form it is currently in unless + there is a good reason to change it. +- if, for some reason, you believe that a particular chunk of existing external + asm could be improved upon further if written in inline asm (or the other + way around), then please make the move from external asm <-> inline asm a + separate patch before your patches that actually improve the asm. + + +Links: +====== +http://www.aggregate.org/MAGIC/ + +x86-specific: +------------- +http://developer.intel.com/design/pentium4/manuals/248966.htm + +The IA-32 Intel Architecture Software Developer's Manual, Volume 2: +Instruction Set Reference +http://developer.intel.com/design/pentium4/manuals/245471.htm + +http://www.agner.org/assem/ + +AMD Athlon Processor x86 Code Optimization Guide: +http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/22007.pdf + + +ARM-specific: +------------- +ARM Architecture Reference Manual (up to ARMv5TE): +http://www.arm.com/community/university/eulaarmarm.html + +Procedure Call Standard for the ARM Architecture: +http://www.arm.com/pdfs/aapcs.pdf + +Optimization guide for ARM9E (used in Nokia 770 Internet Tablet): +http://infocenter.arm.com/help/topic/com.arm.doc.ddi0240b/DDI0240A.pdf +Optimization guide for ARM11 (used in Nokia N800 Internet Tablet): +http://infocenter.arm.com/help/topic/com.arm.doc.ddi0211j/DDI0211J_arm1136_r1p5_trm.pdf +Optimization guide for Intel XScale (used in Sharp Zaurus PDA): +http://download.intel.com/design/intelxscale/27347302.pdf +Intel Wireless MMX 2 Coprocessor: Programmers Reference Manual +http://download.intel.com/design/intelxscale/31451001.pdf + +PowerPC-specific: +----------------- +PowerPC32/AltiVec PIM: +www.freescale.com/files/32bit/doc/ref_manual/ALTIVECPEM.pdf + +PowerPC32/AltiVec PEM: +www.freescale.com/files/32bit/doc/ref_manual/ALTIVECPIM.pdf + +CELL/SPU: +http://www-01.ibm.com/chips/techlib/techlib.nsf/techdocs/30B3520C93F437AB87257060006FFE5E/$file/Language_Extensions_for_CBEA_2.4.pdf +http://www-01.ibm.com/chips/techlib/techlib.nsf/techdocs/9F820A5FFA3ECE8C8725716A0062585F/$file/CBE_Handbook_v1.1_24APR2007_pub.pdf + +GCC asm links: +-------------- +official doc but quite ugly +http://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html + +a bit old (note "+" is valid for input-output, even though the next disagrees) +http://www.cs.virginia.edu/~clc5q/gcc-inline-asm.pdf diff --git a/doc/outdevs.texi b/doc/outdevs.texi new file mode 100644 index 0000000..dd7bd64 --- /dev/null +++ b/doc/outdevs.texi @@ -0,0 +1,33 @@ +@chapter Output Devices +@c man begin OUTPUT DEVICES + +Output devices are configured elements in Libav which allow to write +multimedia data to an output device attached to your system. + +When you configure your Libav build, all the supported output devices +are enabled by default.

Generation of Lt Rt + +In the case when the playback system has analog or digital surround multi-channel capability, a down matrix from 5, 4, or 3 channel to Lt Rt may be desirable. In the case when the number of decoded audio channels exceeds 5, 4 or 3 respectively a first stage down mix to 5, 4 or 3 chs should be used as described above. + +The down matrixing equations for 5-channel source audio to a two-channel Lt Rt playback system are given by: + +Left left+0.7*center-0.7*(lt surround+rt surround) + +Right=right+0.7*center+0.7*(lt surround+rt surround) + +Embedded mixing to 2-channel + +One concern arising from the proliferation of multi-channel audio systems is that most home systems presently have only two channel playback capability. To accommodate this a fixed 2-channel down matrix processes is commonly used following the multi-channel decoding stage. However, for music only applications the image quality etc. of the down matrixed signal may not match that of an equivalent stereo recording found on CD. + +The concept of embedded mixing is to allow the producer to dynamically specify the matrixing coefficients within the audio frame itself. In this way the stereo down mix at the decoder may be better matched to a 2-channel playback environment. + +CHS*2, 7-bit down mix indexes (MCOEFFS) are transmitted along with the multi-channel audio once in every frame.

Although the logic + * is cumbersome, it's straightforward and the resulting code is much + * faster. + * + * A better way to do this would be to pass in the DCT block as a sparse + * matrix, perhaps with the difference cases encoded. + */ + +/** + * @file + * Independent JPEG Group's LLM idct. + */ + +#include "libavutil/common.h" +#include "dct.h" + +#define EIGHT_BIT_SAMPLES + +#define DCTSIZE 8 +#define DCTSIZE2 64 + +#define GLOBAL + +#define RIGHT_SHIFT(x, n) ((x) >> (n)) + +typedef int16_t DCTBLOCK[DCTSIZE2]; + +#define CONST_BITS 13 + +/* + * This routine is specialized to the case DCTSIZE = 8. + */ + +#if DCTSIZE != 8 + Sorry, this code only copes with 8x8 DCTs. /* deliberate syntax err */ +#endif + + +/* + * A 2-D IDCT can be done by 1-D IDCT on each row followed by 1-D IDCT + * on each column. Direct algorithms are also available, but they are + * much more complex and seem not to be any faster when reduced to code. + * + * The poop on this scaling stuff is as follows: + * + * Each 1-D IDCT step produces outputs which are a factor of sqrt(N) + * larger than the true IDCT outputs. The final outputs are therefore + * a factor of N larger than desired; since N=8 this can be cured by + * a simple right shift at the end of the algorithm. The advantage of + * this arrangement is that we save two multiplications per 1-D IDCT, + * because the y0 and y4 inputs need not be divided by sqrt(N). + * + * We have to do addition and subtraction of the integer inputs, which + * is no problem, and multiplication by fractional constants, which is + * a problem to do in integer arithmetic. We multiply all the constants + * by CONST_SCALE and convert them to integer constants (thus retaining + * CONST_BITS bits of precision in the constants). After doing a + * multiplication we have to divide the product by CONST_SCALE, with proper + * rounding, to produce the correct output. This division can be done + * cheaply as a right shift of CONST_BITS bits. We postpone shifting + * as long as possible so that partial sums can be added together with + * full fractional precision. + * + * The outputs of the first pass are scaled up by PASS1_BITS bits so that + * they are represented to better-than-integral precision.

This will be + * used to set the encoding mode. + * + * Rate Control + * VBR mode is turned on by setting CODEC_FLAG_QSCALE in avctx->flags. + * avctx->global_quality is used to set the encoding quality. + * For CBR mode, avctx->bit_rate can be used to set the constant bitrate. + * Alternatively, the 'cbr_quality' option can be set from 0 to 10 to set + * a constant bitrate based on quality. + * For ABR mode, set avctx->bit_rate and set the 'abr' option to 1. + * Approx.

In this case, Speex detects non-speech periods and + * encodes them with just enough bits to reproduce the background noise. + * + * Discontinuous Transmission (DTX) + * DTX is an addition to VAD/VBR operation, that allows to stop transmitting + * completely when the background noise is stationary. + * In file-based operation only 5 bits are used for such frames. + */ + +#include +#include +#include + +#include "libavutil/channel_layout.h" +#include "libavutil/common.h" +#include "libavutil/opt.h" +#include "avcodec.h" +#include "internal.h" +#include "audio_frame_queue.h" + +typedef struct { + AVClass *class; ///< AVClass for private options + SpeexBits bits; ///< libspeex bitwriter context + SpeexHeader header; ///< libspeex header struct + void *enc_state; ///< libspeex encoder state + int frames_per_packet; ///< number of frames to encode in each packet + float vbr_quality; ///< VBR quality 0.0 to 10.0 + int cbr_quality; ///< CBR quality 0 to 10 + int abr; ///< flag to enable ABR + int vad; ///< flag to enable VAD + int dtx; ///< flag to enable DTX + int pkt_frame_count; ///< frame count for the current packet + AudioFrameQueue afq; ///< frame queue +} LibSpeexEncContext; + +static av_cold void print_enc_params(AVCodecContext *avctx, + LibSpeexEncContext *s) +{ + const char *mode_str = "unknown"; + + av_log(avctx, AV_LOG_DEBUG, "channels: %d\n", avctx->channels); + switch (s->header.mode) { + case SPEEX_MODEID_NB: mode_str = "narrowband"; break; + case SPEEX_MODEID_WB: mode_str = "wideband"; break; + case SPEEX_MODEID_UWB: mode_str = "ultra-wideband"; break; + } + av_log(avctx, AV_LOG_DEBUG, "mode: %s\n", mode_str); + if (s->header.vbr) { + av_log(avctx, AV_LOG_DEBUG, "rate control: VBR\n"); + av_log(avctx, AV_LOG_DEBUG, " quality: %f\n", s->vbr_quality); + } else if (s->abr) { + av_log(avctx, AV_LOG_DEBUG, "rate control: ABR\n"); + av_log(avctx, AV_LOG_DEBUG, " bitrate: %d bps\n", avctx->bit_rate); + } else { + av_log(avctx, AV_LOG_DEBUG, "rate control: CBR\n"); + av_log(avctx, AV_LOG_DEBUG, " bitrate: %d bps\n", avctx->bit_rate); + } + av_log(avctx, AV_LOG_DEBUG, "complexity: %d\n", + avctx->compression_level); + av_log(avctx, AV_LOG_DEBUG, "frame size: %d samples\n", + avctx->frame_size); + av_log(avctx, AV_LOG_DEBUG, "frames per packet: %d\n", + s->frames_per_packet); + av_log(avctx, AV_LOG_DEBUG, "packet size: %d\n", + avctx->frame_size * s->frames_per_packet); + av_log(avctx, AV_LOG_DEBUG, "voice activity detection: %d\n", s->vad); + av_log(avctx, AV_LOG_DEBUG, "discontinuous transmission: %d\n", s->dtx); +} + +static av_cold int encode_init(AVCodecContext *avctx) +{ + LibSpeexEncContext *s = avctx->priv_data; + const SpeexMode *mode; + uint8_t *header_data; + int header_size; + int32_t complexity; + + /* channels */ + if (avctx->channels < 1 || avctx->channels > 2) { + av_log(avctx, AV_LOG_ERROR, "Invalid channels (%d).

The VQHD header + * is laid out as: + * + * bytes 0-3 chunk fourcc: 'VQHD' + * bytes 4-7 chunk size in big-endian format, should be 0x0000002A + * bytes 8-49 VQHD chunk data + * + * Bytes 8-49 are what this decoder expects to see. + * + * Briefly, VQA is a vector quantized animation format that operates in a + * VGA palettized colorspace. It operates on pixel vectors (blocks) + * of either 4x2 or 4x4 in size. Compressed VQA chunks can contain vector + * codebooks, palette information, and code maps for rendering vectors onto + * frames. Any of these components can also be compressed with a run-length + * encoding (RLE) algorithm commonly referred to as "format80". + * + * VQA takes a novel approach to rate control. Each group of n frames + * (usually, n = 8) relies on a different vector codebook. Rather than + * transporting an entire codebook every 8th frame, the new codebook is + * broken up into 8 pieces and sent along with the compressed video chunks + * for each of the 8 frames preceding the 8 frames which require the + * codebook. A full codebook is also sent on the very first frame of a + * file. This is an interesting technique, although it makes random file + * seeking difficult despite the fact that the frames are all intracoded. + * + * V1,2 VQA uses 12-bit codebook indexes. If the 12-bit indexes were + * packed into bytes and then RLE compressed, bytewise, the results would + * be poor. That is why the coding method divides each index into 2 parts, + * the top 4 bits and the bottom 8 bits, then RL encodes the 4-bit pieces + * together and the 8-bit pieces together. If most of the vectors are + * clustered into one group of 256 vectors, most of the 4-bit index pieces + * should be the same. + */ + +#include +#include +#include + +#include "libavutil/intreadwrite.h" +#include "libavutil/imgutils.h" +#include "avcodec.h" +#include "bytestream.h" +#include "internal.h" + +#define PALETTE_COUNT 256 +#define VQA_HEADER_SIZE 0x2A + +/* allocate the maximum vector space, regardless of the file version: + * (0xFF00 codebook vectors + 0x100 solid pixel vectors) * (4x4 pixels/block) */ +#define MAX_CODEBOOK_VECTORS 0xFF00 +#define SOLID_PIXEL_VECTORS 0x100 +#define MAX_VECTORS (MAX_CODEBOOK_VECTORS + SOLID_PIXEL_VECTORS) +#define MAX_CODEBOOK_SIZE (MAX_VECTORS * 4 * 4) + +#define CBF0_TAG MKBETAG('C', 'B', 'F', '0') +#define CBFZ_TAG MKBETAG('C', 'B', 'F', 'Z') +#define CBP0_TAG MKBETAG('C', 'B', 'P', '0') +#define CBPZ_TAG MKBETAG('C', 'B', 'P', 'Z') +#define CPL0_TAG MKBETAG('C', 'P', 'L', '0') +#define CPLZ_TAG MKBETAG('C', 'P', 'L', 'Z') +#define VPTZ_TAG MKBETAG('V', 'P', 'T', 'Z') + +typedef struct VqaContext { + + AVCodecContext *avctx;

Every subframe contains the data for 2^N time domain samples + * where N varies between 7 and 12. + * + * Example wmapro bitstream (in samples): + * + * || packet 0 || packet 1 || packet 2 packets + * --------------------------------------------------- + * || frame 0 || frame 1 || frame 2 || frames + * --------------------------------------------------- + * || | | || | | | || || subframes of channel 0 + * --------------------------------------------------- + * || | | || | | | || || subframes of channel 1 + * --------------------------------------------------- + * + * The frame layouts for the individual channels of a wma frame does not need + * to be the same. + * + * However, if the offsets and lengths of several subframes of a frame are the + * same, the subframes of the channels can be grouped. + * Every group may then use special coding techniques like M/S stereo coding + * to improve the compression ratio. These channel transformations do not + * need to be applied to a whole subframe. Instead, they can also work on + * individual scale factor bands (see below). + * The coefficients that carry the audio signal in the frequency domain + * are transmitted as huffman-coded vectors with 4, 2 and 1 elements. + * In addition to that, the encoder can switch to a runlevel coding scheme + * by transmitting subframe_length / 128 zero coefficients. + * + * Before the audio signal can be converted to the time domain, the + * coefficients have to be rescaled and inverse quantized. + * A subframe is therefore split into several scale factor bands that get + * scaled individually. + * Scale factors are submitted for every frame but they might be shared + * between the subframes of a channel. Scale factors are initially DPCM-coded. + * Once scale factors are shared, the differences are transmitted as runlevel + * codes. + * Every subframe length and offset combination in the frame layout shares a + * common quantization factor that can be adjusted for every channel by a + * modifier. + * After the inverse quantization, the coefficients get processed by an IMDCT. + * The resulting values are then windowed with a sine window and the first half + * of the values are added to the second half of the output from the previous + * subframe in order to reconstruct the output samples. + */ + +#include + +#include "libavutil/float_dsp.h" +#include "libavutil/intfloat.h" +#include "libavutil/intreadwrite.h" +#include "avcodec.h" +#include "internal.h" +#include "get_bits.h" +#include "put_bits.h" +#include "wmaprodata.h" +#include "sinewin.h" +#include "wma.h" +#include "wma_common.h" + +/** current decoder limitations */ +#define WMAPRO_MAX_CHANNELS 8 ///< max number of handled channels +#define MAX_SUBFRAMES 32 ///< max number of subframes per channel +#define MAX_BANDS 29 ///< max number of scale factor bands +#define MAX_FRAMESIZE 32768 ///< maximum compressed frame size + +#define WMAPRO_BLOCK_MIN_BITS 6 ///< log2 of min block size +#define WMAPRO_BLOCK_MAX_BITS 13 ///< log2 of max block size +#define WMAPRO_BLOCK_MIN_SIZE (1 << WMAPRO_BLOCK_MIN_BITS) ///< minimum block size +#define WMAPRO_BLOCK_MAX_SIZE (1 << WMAPRO_BLOCK_MAX_BITS) ///< maximum block size +#define WMAPRO_BLOCK_SIZES (WMAPRO_BLOCK_MAX_BITS - WMAPRO_BLOCK_MIN_BITS + 1) ///< possible block sizes + + +#define VLCBITS 9 +#define SCALEVLCBITS 8 +#define VEC4MAXDEPTH ((HUFF_VEC4_MAXBITS+VLCBITS-1)/VLCBITS) +#define VEC2MAXDEPTH ((HUFF_VEC2_MAXBITS+VLCBITS-1)/VLCBITS) +#define VEC1MAXDEPTH ((HUFF_VEC1_MAXBITS+VLCBITS-1)/VLCBITS) +#define SCALEMAXDEPTH ((HUFF_SCALE_MAXBITS+SCALEVLCBITS-1)/SCALEVLCBITS) +#define SCALERLMAXDEPTH ((HUFF_SCALE_RL_MAXBITS+VLCBITS-1)/VLCBITS) + +static VLC sf_vlc;

The FD may be set for non-blocking I/O, + in which case you can use select() or poll() to wait for output + buffer space. + + To set the DV output parameters (e.g. whether you want NTSC or PAL + video), use the DV1394_INIT ioctl, passing in the parameters you + want in a struct dv1394_init. + + Example 1: + To play a raw .DV file: cat foo.DV > /dev/dv1394 + (cat will use write() internally) + + Example 2: + static struct dv1394_init init = { + 0x63, (broadcast channel) + 4, (four-frame ringbuffer) + DV1394_NTSC, (send NTSC video) + 0, 0 (default empty packet rate) + } + + ioctl(fd, DV1394_INIT, &init); + + while(1) { + read( , buf, DV1394_NTSC_FRAME_SIZE ); + write( , buf, DV1394_NTSC_FRAME_SIZE ); + } + + 2) + + For more control over buffering, and to avoid unnecessary copies + of the DV data, you can use the more sophisticated the mmap() interface. + First, call the DV1394_INIT ioctl to specify your parameters, + including the number of frames in the ringbuffer. Then, calling mmap() + on the dv1394 device will give you direct access to the ringbuffer + from which the DV card reads your frame data. + + The ringbuffer is simply one large, contiguous region of memory + containing two or more frames of packed DV data. Each frame of DV data + is 120000 bytes (NTSC) or 144000 bytes (PAL). + + Fill one or more frames in the ringbuffer, then use the DV1394_SUBMIT_FRAMES + ioctl to begin I/O. You can use either the DV1394_WAIT_FRAMES ioctl + or select()/poll() to wait until the frames are transmitted. Next, you'll + need to call the DV1394_GET_STATUS ioctl to determine which ringbuffer + frames are clear (ready to be filled with new DV data). Finally, use + DV1394_SUBMIT_FRAMES again to send the new data to the DV output. + + + Example: here is what a four-frame ringbuffer might look like + during DV transmission: + + + frame 0 frame 1 frame 2 frame 3 + + *--------------------------------------* + | CLEAR | DV data | DV data | CLEAR | + *--------------------------------------* + + + transmission goes in this direction --->>> + + + The DV hardware is currently transmitting the data in frame 1. + Once frame 1 is finished, it will automatically transmit frame 2. + (if frame 2 finishes before frame 3 is submitted, the device + will continue to transmit frame 2, and will increase the dropped_frames + counter each time it repeats the transmission). + + + If you called DV1394_GET_STATUS at this instant, you would + receive the following values: + + n_frames = 4 + active_frame = 1 + first_clear_frame = 3 + n_clear_frames = 2 + + At this point, you should write new DV data into frame 3 and optionally + frame 0. Then call DV1394_SUBMIT_FRAMES to inform the device that + it may transmit the new frames. + + ERROR HANDLING + + An error (buffer underflow/overflow or a break in the DV stream due + to a 1394 bus reset) can be detected by checking the dropped_frames + field of struct dv1394_status (obtained through the + DV1394_GET_STATUS ioctl). + + The best way to recover from such an error is to re-initialize + dv1394, either by using the DV1394_INIT ioctl call, or closing the + file descriptor and opening it again. (note that you must unmap all + ringbuffer mappings when closing the file descriptor, or else + dv1394 will still be considered 'in use'). + + MAIN LOOP + + For maximum efficiency and robustness against bus errors, you are + advised to model the main loop of your application after the + following pseudo-code example: + + (checks of system call return values omitted for brevity; always + check return values in your code!) + + while( frames left ) { + + struct pollfd *pfd = ...; + + pfd->fd = dv1394_fd; + pfd->revents = 0; + pfd->events = POLLOUT | POLLIN; (OUT for transmit, IN for receive) + + (add other sources of I/O here) + + poll(pfd, 1, -1); (or select(); add a timeout if you want) + + if(pfd->revents) { + struct dv1394_status status; + + ioctl(dv1394_fd, DV1394_GET_STATUS, &status); + + if(status.dropped_frames > 0) { + reset_dv1394(); + } else { + int i; + for (i = 0; i < status.n_clear_frames; i++) { + copy_DV_frame(); + } + } + } + } + + where copy_DV_frame() reads or writes on the dv1394 file descriptor + (read/write mode) or copies data to/from the mmap ringbuffer and + then calls ioctl(DV1394_SUBMIT_FRAMES) to notify dv1394 that new + frames are available (mmap mode). + + reset_dv1394() is called in the event of a buffer + underflow/overflow or a halt in the DV stream (e.g. due to a 1394 + bus reset).

However, + we have exposed the empty packet rate as a parameter to support devices that + do not work with the default rate. + + The decision to insert an empty packet is made with a numerator/denominator + algorithm.

Its main two purposes are demuxing - i.e. splitting a media file + * into component streams, and the reverse process of muxing - writing supplied + * data in a specified container format. It also has an @ref lavf_io + * "I/O module" which supports a number of protocols for accessing the data (e.g. + * file, tcp, http and others). Before using lavf, you need to call + * av_register_all() to register all compiled muxers, demuxers and protocols. + * Unless you are absolutely sure you won't use libavformat's network + * capabilities, you should also call avformat_network_init(). + * + * A supported input format is described by an AVInputFormat struct, conversely + * an output format is described by AVOutputFormat. You can iterate over all + * registered input/output formats using the av_iformat_next() / + * av_oformat_next() functions. The protocols layer is not part of the public + * API, so you can only get the names of supported protocols with the + * avio_enum_protocols() function. + * + * Main lavf structure used for both muxing and demuxing is AVFormatContext, + * which exports all information about the file being read or written. As with + * most Libav structures, its size is not part of public ABI, so it cannot be + * allocated on stack or directly with av_malloc(). To create an + * AVFormatContext, use avformat_alloc_context() (some functions, like + * avformat_open_input() might do that for you). + * + * Most importantly an AVFormatContext contains: + * @li the @ref AVFormatContext.iformat "input" or @ref AVFormatContext.oformat + * "output" format. It is either autodetected or set by user for input; + * always set by user for output. + * @li an @ref AVFormatContext.streams "array" of AVStreams, which describe all + * elementary streams stored in the file. AVStreams are typically referred to + * using their index in this array. + * @li an @ref AVFormatContext.pb "I/O context". It is either opened by lavf or + * set by user for input, always set by user for output (unless you are dealing + * with an AVFMT_NOFILE format). + * + * @section lavf_options Passing options to (de)muxers + * Lavf allows to configure muxers and demuxers using the @ref avoptions + * mechanism. Generic (format-independent) libavformat options are provided by + * AVFormatContext, they can be examined from a user program by calling + * av_opt_next() / av_opt_find() on an allocated AVFormatContext (or its AVClass + * from avformat_get_class()). Private (format-specific) options are provided by + * AVFormatContext.priv_data if and only if AVInputFormat.priv_class / + * AVOutputFormat.priv_class of the corresponding format struct is non-NULL. + * Further options may be provided by the @ref AVFormatContext.pb "I/O context", + * if its AVClass is non-NULL, and the protocols layer. See the discussion on + * nesting in @ref avoptions documentation to learn how to access those. + * + * @defgroup lavf_decoding Demuxing + * @{ + * Demuxers read a media file and split it into chunks of data (@em packets). A + * @ref AVPacket "packet" contains one or more encoded frames which belongs to a + * single elementary stream. In the lavf API this process is represented by the + * avformat_open_input() function for opening a file, av_read_frame() for + * reading a single packet and finally avformat_close_input(), which does the + * cleanup. + * + * @section lavf_decoding_open Opening a media file + * The minimum information required to open a file is its URL or filename, which + * is passed to avformat_open_input(), as in the following code: + * @code + * const char *url = "in.mp3"; + * AVFormatContext *s = NULL; + * int ret = avformat_open_input(&s, url, NULL, NULL); + * if (ret < 0) + * abort(); + * @endcode + * The above code attempts to allocate an AVFormatContext, open the + * specified file (autodetecting the format) and read the header, exporting the + * information stored there into s. Some formats do not have a header or do not + * store enough information there, so it is recommended that you call the + * avformat_find_stream_info() function which tries to read and decode a few + * frames to find missing information. + * + * In some cases you might want to preallocate an AVFormatContext yourself with + * avformat_alloc_context() and do some tweaking on it before passing it to + * avformat_open_input(). One such case is when you want to use custom functions + * for reading input data instead of lavf internal I/O layer. + * To do that, create your own AVIOContext with avio_alloc_context(), passing + * your reading callbacks to it. Then set the @em pb field of your + * AVFormatContext to newly created AVIOContext. + * + * Since the format of the opened file is in general not known until after + * avformat_open_input() has returned, it is not possible to set demuxer private + * options on a preallocated context. Instead, the options should be passed to + * avformat_open_input() wrapped in an AVDictionary: + * @code + * AVDictionary *options = NULL; + * av_dict_set(&options, "video_size", "640x480", 0); + * av_dict_set(&options, "pixel_format", "rgb24", 0); + * + * if (avformat_open_input(&s, url, NULL, &options) < 0) + * abort(); + * av_dict_free(&options); + * @endcode + * This code passes the private options 'video_size' and 'pixel_format' to the + * demuxer. They would be necessary for e.g. the rawvideo demuxer, since it + * cannot know how to interpret raw video data otherwise. If the format turns + * out to be something different than raw video, those options will not be + * recognized by the demuxer and therefore will not be applied. Such unrecognized + * options are then returned in the options dictionary (recognized options are + * consumed). The calling program can handle such unrecognized options as it + * wishes, e.g. + * @code + * AVDictionaryEntry *e; + * if (e = av_dict_get(options, "", NULL, AV_DICT_IGNORE_SUFFIX)) { + * fprintf(stderr, "Option %s not recognized by the demuxer.\n", e->key); + * abort(); + * } + * @endcode + * + * After you have finished reading the file, you must close it with + * avformat_close_input(). It will free everything associated with the file. + * + * @section lavf_decoding_read Reading from an opened file + * Reading data from an opened AVFormatContext is done by repeatedly calling + * av_read_frame() on it. Each call, if successful, will return an AVPacket + * containing encoded data for one AVStream, identified by + * AVPacket.stream_index. This packet may be passed straight into the libavcodec + * decoding functions avcodec_decode_video2(), avcodec_decode_audio4() or + * avcodec_decode_subtitle2() if the caller wishes to decode the data. + * + * AVPacket.pts, AVPacket.dts and AVPacket.duration timing information will be + * set if known. They may also be unset (i.e. AV_NOPTS_VALUE for + * pts/dts, 0 for duration) if the stream does not provide them. The timing + * information will be in AVStream.time_base units, i.e. it has to be + * multiplied by the timebase to convert them to seconds. + * + * If AVPacket.buf is set on the returned packet, then the packet is + * allocated dynamically and the user may keep it indefinitely. + * Otherwise, if AVPacket.buf is NULL, the packet data is backed by a + * static storage somewhere inside the demuxer and the packet is only valid + * until the next av_read_frame() call or closing the file. If the caller + * requires a longer lifetime, av_dup_packet() will make an av_malloc()ed copy + * of it. + * In both cases, the packet must be freed with av_free_packet() when it is no + * longer needed. + * + * @section lavf_decoding_seek Seeking + * @} + * + * @defgroup lavf_encoding Muxing + * @{ + * Muxers take encoded data in the form of @ref AVPacket "AVPackets" and write + * it into files or other output bytestreams in the specified container format. + * + * The main API functions for muxing are avformat_write_header() for writing the + * file header, av_write_frame() / av_interleaved_write_frame() for writing the + * packets and av_write_trailer() for finalizing the file. + * + * At the beginning of the muxing process, the caller must first call + * avformat_alloc_context() to create a muxing context. The caller then sets up + * the muxer by filling the various fields in this context: + * + * - The @ref AVFormatContext.oformat "oformat" field must be set to select the + * muxer that will be used. + * - Unless the format is of the AVFMT_NOFILE type, the @ref AVFormatContext.pb + * "pb" field must be set to an opened IO context, either returned from + * avio_open2() or a custom one. + * - Unless the format is of the AVFMT_NOSTREAMS type, at least one stream must + * be created with the avformat_new_stream() function. The caller should fill + * the @ref AVStream.codec "stream codec context" information, such as the + * codec @ref AVCodecContext.codec_type "type", @ref AVCodecContext.codec_id + * "id" and other parameters (e.g. width / height, the pixel or sample format, + * etc.) as known. The @ref AVStream.time_base "stream timebase" should + * be set to the timebase that the caller desires to use for this stream (note + * that the timebase actually used by the muxer can be different, as will be + * described later). + * - The caller may fill in additional information, such as @ref + * AVFormatContext.metadata "global" or @ref AVStream.metadata "per-stream" + * metadata, @ref AVFormatContext.chapters "chapters", @ref + * AVFormatContext.programs "programs", etc. as described in the + * AVFormatContext documentation. Whether such information will actually be + * stored in the output depends on what the container format and the muxer + * support. + * + * When the muxing context is fully set up, the caller must call + * avformat_write_header() to initialize the muxer internals and write the file + * header. Whether anything actually is written to the IO context at this step + * depends on the muxer, but this function must always be called. Any muxer + * private options must be passed in the options parameter to this function. + * + * The data is then sent to the muxer by repeatedly calling av_write_frame() or + * av_interleaved_write_frame() (consult those functions' documentation for + * discussion on the difference between them; only one of them may be used with + * a single muxing context, they should not be mixed). Do note that the timing + * information on the packets sent to the muxer must be in the corresponding + * AVStream's timebase. That timebase is set by the muxer (in the + * avformat_write_header() step) and may be different from the timebase + * requested by the caller. + * + * Once all the data has been written, the caller must call av_write_trailer() + * to flush any buffered packets and finalize the output file, then close the IO + * context (if any) and finally free the muxing context with + * avformat_free_context(). + * @} + * + * @defgroup lavf_io I/O Read/Write + * @{ + * @} + * + * @defgroup lavf_codec Demuxers + * @{ + * @defgroup lavf_codec_native Native Demuxers + * @{ + * @} + * @defgroup lavf_codec_wrappers External library wrappers + * @{ + * @} + * @} + * @defgroup lavf_protos I/O Protocols + * @{ + * @} + * @defgroup lavf_internal Internal + * @{ + * @} + * @} + * + */ + +#include +#include /* FILE */ +#include "libavcodec/avcodec.h" +#include "libavutil/dict.h" +#include "libavutil/log.h" + +#include "avio.h" +#include "libavformat/version.h" + +struct AVFormatContext; + + +/** + * @defgroup metadata_api Public Metadata API + * @{ + * @ingroup libavf + * The metadata API allows libavformat to export metadata tags to a client + * application when demuxing.

In this example, all authors must be + * placed in the same tag. + * - Metadata is flat, not hierarchical; there are no subtags. If you + * want to store, e.g., the email address of the child of producer Alice + * and actor Bob, that could have key=alice_and_bobs_childs_email_address. + * - Several modifiers can be applied to the tag name. This is done by + * appending a dash character ('-') and the modifier name in the order + * they appear in the list below -- e.g. foo-eng-sort, not foo-sort-eng. + * - language -- a tag whose value is localized for a particular language + * is appended with the ISO 639-2/B 3-letter language code. + * For example: Author-ger=Michael, Author-eng=Mike + * The original/default language is in the unqualified "Author" tag. + * A demuxer should set a default if it sets any translated tag. + * - sorting -- a modified version of a tag that should be used for + * sorting will have '-sort' appended. E.g. artist="The Beatles", + * artist-sort="Beatles, The". + * - Some protocols and demuxers support metadata updates. After a successful + * call to av_read_packet(), AVFormatContext.event_flags or AVStream.event_flags + * will be updated to indicate if metadata changed. In order to detect metadata + * changes on a stream, you need to loop through all streams in the AVFormatContext + * and check their individual event_flags. + * + * - Demuxers attempt to export metadata in a generic format, however tags + * with no generic equivalents are left as they are stored in the container. + * Follows a list of generic tag names: + * + @verbatim + album -- name of the set this work belongs to + album_artist -- main creator of the set/album, if different from artist. + e.g. "Various Artists" for compilation albums. + artist -- main creator of the work + comment -- any additional description of the file. + composer -- who composed the work, if different from artist. + copyright -- name of copyright holder. + creation_time-- date when the file was created, preferably in ISO 8601. + date -- date when the work was created, preferably in ISO 8601. + disc -- number of a subset, e.g. disc in a multi-disc collection. + encoder -- name/settings of the software/hardware that produced the file. + encoded_by -- person/group who created the file. + filename -- original name of the file. + genre -- . + language -- main language in which the work is performed, preferably + in ISO 639-2 format. Multiple languages can be specified by + separating them with commas. + performer -- artist who performed the work, if different from artist. + E.g for "Also sprach Zarathustra", artist would be "Richard + Strauss" and performer "London Philharmonic Orchestra". + publisher -- name of the label/publisher. + service_name -- name of the service in broadcasting (channel name). + service_provider -- name of the service provider in broadcasting. + title -- name of the work. + track -- number of this work in the set, can be in form current/total. + variant_bitrate -- the total bitrate of the bitrate variant that the current stream is part of + @endverbatim + * + * Look in the examples section for an application example how to use the Metadata API. + * + * @} + */ + +/* packet functions */ + + +/** + * Allocate and read the payload of a packet and initialize its + * fields with default values. + * + * @param s associated IO context + * @param pkt packet + * @param size desired payload size + * @return >0 (read size) if OK, AVERROR_xxx otherwise + */ +int av_get_packet(AVIOContext *s, AVPacket *pkt, int size); + + +/** + * Read data and append it to the current content of the AVPacket. + * If pkt->size is 0 this is identical to av_get_packet. + * Note that this uses av_grow_packet and thus involves a realloc + * which is inefficient.

Here are some notes + * for anyone trying to understand the technical details of this format: + * + * The format has no definite file signature. This is problematic for a + * general-purpose media player that wants to automatically detect file + * types. However, a CIN file does start with 5 32-bit numbers that + * specify audio and video parameters. This demuxer gets around the lack + * of file signature by performing sanity checks on those parameters. + * Probabalistically, this is a reasonable solution since the number of + * valid combinations of the 5 parameters is a very small subset of the + * total 160-bit number space. + * + * Refer to the function idcin_probe() for the precise A/V parameters + * that this demuxer allows. + * + * Next, each audio and video frame has a duration of 1/14 sec. If the + * audio sample rate is a multiple of the common frequency 22050 Hz it will + * divide evenly by 14. However, if the sample rate is 11025 Hz: + * 11025 (samples/sec) / 14 (frames/sec) = 787.5 (samples/frame) + * The way the CIN stores audio in this case is by storing 787 sample + * frames in the first audio frame and 788 sample frames in the second + * audio frame. Therefore, the total number of bytes in an audio frame + * is given as: + * audio frame #0: 787 * (bytes/sample) * (# channels) bytes in frame + * audio frame #1: 788 * (bytes/sample) * (# channels) bytes in frame + * audio frame #2: 787 * (bytes/sample) * (# channels) bytes in frame + * audio frame #3: 788 * (bytes/sample) * (# channels) bytes in frame + * + * Finally, not all id CIN creation tools agree on the resolution of the + * color palette, apparently. Some creation tools specify red, green, and + * blue palette components in terms of 6-bit VGA color DAC values which + * range from 0..63. Other tools specify the RGB components as full 8-bit + * values that range from 0..255.

It is opaque, so all parameters + * must be set with the @ref avoptions API. + * + * For example the following code will setup conversion from planar float sample + * format to interleaved signed 16-bit integer, downsampling from 48kHz to + * 44.1kHz and downmixing from 5.1 channels to stereo (using the default mixing + * matrix): + * @code + * AVAudioResampleContext *avr = avresample_alloc_context(); + * av_opt_set_int(avr, "in_channel_layout", AV_CH_LAYOUT_5POINT1, 0); + * av_opt_set_int(avr, "out_channel_layout", AV_CH_LAYOUT_STEREO, 0); + * av_opt_set_int(avr, "in_sample_rate", 48000, 0); + * av_opt_set_int(avr, "out_sample_rate", 44100, 0); + * av_opt_set_int(avr, "in_sample_fmt", AV_SAMPLE_FMT_FLTP, 0); + * av_opt_set_int(avr, "out_sample_fmt", AV_SAMPLE_FMT_S16, 0); + * @endcode + * + * Once the context is initialized, it must be opened with avresample_open(). If + * you need to change the conversion parameters, you must close the context with + * avresample_close(), change the parameters as described above, then reopen it + * again. + * + * The conversion itself is done by repeatedly calling avresample_convert(). + * Note that the samples may get buffered in two places in lavr. The first one + * is the output FIFO, where the samples end up if the output buffer is not + * large enough. The data stored in there may be retrieved at any time with + * avresample_read(). The second place is the resampling delay buffer, + * applicable only when resampling is done. The samples in it require more input + * before they can be processed.

Each AVOption must have a non-empty name, a type, a default + * value and for number-type AVOptions also a range of allowed values. It must + * also declare an offset in bytes from the start of the struct, where the field + * associated with this AVOption is located. Other fields in the AVOption struct + * should also be set when applicable, but are not required. + * + * The following example illustrates an AVOptions-enabled struct: + * @code + * typedef struct test_struct { + * AVClass *class; + * int int_opt; + * char *str_opt; + * uint8_t *bin_opt; + * int bin_len; + * } test_struct; + * + * static const AVOption test_options[] = { + * { "test_int", "This is a test option of int type.", offsetof(test_struct, int_opt), + * AV_OPT_TYPE_INT, { .i64 = -1 }, INT_MIN, INT_MAX }, + * { "test_str", "This is a test option of string type.", offsetof(test_struct, str_opt), + * AV_OPT_TYPE_STRING }, + * { "test_bin", "This is a test option of binary type.", offsetof(test_struct, bin_opt), + * AV_OPT_TYPE_BINARY }, + * { NULL }, + * }; + * + * static const AVClass test_class = { + * .class_name = "test class", + * .item_name = av_default_item_name, + * .option = test_options, + * .version = LIBAVUTIL_VERSION_INT, + * }; + * @endcode + * + * Next, when allocating your struct, you must ensure that the AVClass pointer + * is set to the correct value. Then, av_opt_set_defaults() must be called to + * initialize defaults. After that the struct is ready to be used with the + * AVOptions API. + * + * When cleaning up, you may use the av_opt_free() function to automatically + * free all the allocated string and binary options. + * + * Continuing with the above example: + * + * @code + * test_struct *alloc_test_struct(void) + * { + * test_struct *ret = av_malloc(sizeof(*ret)); + * ret->class = &test_class; + * av_opt_set_defaults(ret); + * return ret; + * } + * void free_test_struct(test_struct **foo) + * { + * av_opt_free(*foo); + * av_freep(foo); + * } + * @endcode + * + * @subsection avoptions_implement_nesting Nesting + * It may happen that an AVOptions-enabled struct contains another + * AVOptions-enabled struct as a member (e.g. AVCodecContext in + * libavcodec exports generic options, while its priv_data field exports + * codec-specific options). In such a case, it is possible to set up the + * parent struct to export a child's options. To do that, simply + * implement AVClass.child_next() and AVClass.child_class_next() in the + * parent struct's AVClass. + * Assuming that the test_struct from above now also contains a + * child_struct field: + * + * @code + * typedef struct child_struct { + * AVClass *class; + * int flags_opt; + * } child_struct; + * static const AVOption child_opts[] = { + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX }, + * { NULL }, + * }; + * static const AVClass child_class = { + * .class_name = "child class", + * .item_name = av_default_item_name, + * .option = child_opts, + * .version = LIBAVUTIL_VERSION_INT, + * }; + * + * void *child_next(void *obj, void *prev) + * { + * test_struct *t = obj; + * if (!prev && t->child_struct) + * return t->child_struct; + * return NULL + * } + * const AVClass child_class_next(const AVClass *prev) + * { + * return prev ? NULL : &child_class; + * } + * @endcode + * Putting child_next() and child_class_next() as defined above into + * test_class will now make child_struct's options accessible through + * test_struct (again, proper setup as described above needs to be done on + * child_struct right after it is created). + * + * From the above example it might not be clear why both child_next() + * and child_class_next() are needed. The distinction is that child_next() + * iterates over actually existing objects, while child_class_next() + * iterates over all possible child classes. E.g. if an AVCodecContext + * was initialized to use a codec which has private options, then its + * child_next() will return AVCodecContext.priv_data and finish + * iterating. OTOH child_class_next() on AVCodecContext.av_class will + * iterate over all available codecs with private options. + * + * @subsection avoptions_implement_named_constants Named constants + * It is possible to create named constants for options. Simply set the unit + * field of the option the constants should apply to to a string and + * create the constants themselves as options of type AV_OPT_TYPE_CONST + * with their unit field set to the same string. + * Their default_val field should contain the value of the named + * constant. + * For example, to add some named constants for the test_flags option + * above, put the following into the child_opts array: + * @code + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX, "test_unit" }, + * { "flag1", "This is a flag with value 16", 0, AV_OPT_TYPE_CONST, { .i64 = 16 }, 0, 0, "test_unit" }, + * @endcode + * + * @section avoptions_use Using AVOptions + * This section deals with accessing options in an AVOptions-enabled struct. + * Such structs in Libav are e.g. AVCodecContext in libavcodec or + * AVFormatContext in libavformat. + * + * @subsection avoptions_use_examine Examining AVOptions + * The basic functions for examining options are av_opt_next(), which iterates + * over all options defined for one object, and av_opt_find(), which searches + * for an option with the given name. + * + * The situation is more complicated with nesting. An AVOptions-enabled struct + * may have AVOptions-enabled children. Passing the AV_OPT_SEARCH_CHILDREN flag + * to av_opt_find() will make the function search children recursively. + * + * For enumerating there are basically two cases. The first is when you want to + * get all options that may potentially exist on the struct and its children + * (e.g. when constructing documentation). In that case you should call + * av_opt_child_class_next() recursively on the parent struct's AVClass. The + * second case is when you have an already initialized struct with all its + * children and you want to get all options that can be actually written or read + * from it. In that case you should call av_opt_child_next() recursively (and + * av_opt_next() on each result). + * + * @subsection avoptions_use_get_set Reading and writing AVOptions + * When setting options, you often have a string read directly from the + * user. In such a case, simply passing it to av_opt_set() is enough. For + * non-string type options, av_opt_set() will parse the string according to the + * option type. + * + * Similarly av_opt_get() will read any option type and convert it to a string + * which will be returned. Do not forget that the string is allocated, so you + * have to free it with av_free(). + * + * In some cases it may be more convenient to put all options into an + * AVDictionary and call av_opt_set_dict() on it. A specific case of this + * are the format/codec open functions in lavf/lavc which take a dictionary + * filled with option as a parameter. This allows to set some options + * that cannot be set otherwise, since e.g. the input file format is not known + * before the file is actually opened. + */ + +enum AVOptionType{ + AV_OPT_TYPE_FLAGS, + AV_OPT_TYPE_INT, + AV_OPT_TYPE_INT64, + AV_OPT_TYPE_DOUBLE, + AV_OPT_TYPE_FLOAT, + AV_OPT_TYPE_STRING, + AV_OPT_TYPE_RATIONAL, + AV_OPT_TYPE_BINARY, ///< offset must point to a pointer immediately followed by an int for the length + AV_OPT_TYPE_DICT, + AV_OPT_TYPE_CONST = 128, +}; + +/** + * AVOption + */ +typedef struct AVOption { + const char *name; + + /** + * short English help text + * @todo What about other languages? + */ + const char *help; + + /** + * The offset relative to the context structure where the option + * value is stored.
