- * Identify the syntax and semantics of the bitstream.
- * The principle is roughly:
- * Two decoders with the same ID can decode the same streams.
- * Two encoders with the same ID can encode compatible streams.
- * There may be slight deviations from the principle due to implementation
- * details.
- *
- * If you add a codec ID to this list, add it so that
- * 1. no value of a existing codec ID changes (that would break ABI),
- * 2. Give it a value which when taken as ASCII is recognized uniquely by a human as this specific codec.
- * This ensures that 2 forks can independently add AVCodecIDs without producing conflicts.
- *
- * After adding new codec IDs, do not forget to add an entry to the codec
- * descriptor list and bump libavcodec minor version.

- * @defgroup libavf I/O and Muxing/Demuxing Library
- * @{
- *
- * Libavformat (lavf) is a library for dealing with various media container
- * formats. 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 Libavformat 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 metadata_api Public Metadata API
- * @{
- * @ingroup libavf
- * The metadata API allows libavformat to export metadata tags to a client
- * application when demuxing. Conversely it allows a client application to
- * set metadata when muxing.
- *
- * Metadata is exported or set as pairs of key/value strings in the 'metadata'
- * fields of the AVFormatContext, AVStream, AVChapter and AVProgram structs
- * using the @ref lavu_dict "AVDictionary" API. Like all strings in FFmpeg,
- * metadata is assumed to be UTF-8 encoded Unicode. Note that metadata
- * exported by demuxers isn't checked to be valid UTF-8 in most cases.
- *
- * Important concepts to keep in mind:
- * - Keys are unique; there can never be 2 tags with the same key. This is
- * also meant semantically, i.e., a demuxer should not knowingly produce
- * several keys that are literally different but semantically identical.
- * E.g., key=Author5, key=Author6. 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 -- <self-evident>.
- 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

- * @section ffmpeg_intro Introduction
- *
- * This document describes the usage of the different libraries
- * provided by FFmpeg.
- *
- * @li @ref libavc "libavcodec" encoding/decoding library
- * @li @ref lavfi "libavfilter" graph-based frame editing library
- * @li @ref libavf "libavformat" I/O and muxing/demuxing library
- * @li @ref lavd "libavdevice" special devices muxing/demuxing library
- * @li @ref lavu "libavutil" common utility library
- * @li @ref lswr "libswresample" audio resampling, format conversion and mixing
- * @li @ref lpp "libpostproc" post processing library
- * @li @ref libsws "libswscale" color conversion and scaling library
- *
- * @section ffmpeg_versioning Versioning and compatibility
- *
- * Each of the FFmpeg libraries contains a version.h header, which defines a
- * major, minor and micro version number with the
- * <em>LIBRARYNAME_VERSION_{MAJOR,MINOR,MICRO}</em> macros. The major version
- * number is incremented with backward incompatible changes - e.g. removing
- * parts of the public API, reordering public struct members, etc. The minor
- * version number is incremented for backward compatible API changes or major
- * new features - e.g. adding a new public function or a new decoder. The micro
- * version number is incremented for smaller changes that a calling program
- * might still want to check for - e.g. changing behavior in a previously
- * unspecified situation.
- *
- * FFmpeg guarantees backward API and ABI compatibility for each library as long
- * as its major version number is unchanged. This means that no public symbols
- * will be removed or renamed. Types and names of the public struct members and
- * values of public macros and enums will remain the same (unless they were
- * explicitly declared as not part of the public API). Documented behavior will
- * not change.
- *
- * In other words, any correct program that works with a given FFmpeg snapshot
- * should work just as well without any changes with any later snapshot with the
- * same major versions. This applies to both rebuilding the program against new
- * FFmpeg versions or to replacing the dynamic FFmpeg libraries that a program
- * links against.
- *
- * However, new public symbols may be added and new members may be appended to
- * public structs whose size is not part of public ABI (most public structs in
- * FFmpeg). New macros and enum values may be added. Behavior in undocumented
- * situations may change slightly (and be documented). All those are accompanied
- * by an entry in doc/APIchanges and incrementing either the minor or micro
- * version number.

- *
- * Small buffers are kept in the structure itself, and thus require no

- * after the structure goes out of scope). This is almost as lightweight as
- * declaring a local "char buf[512]".

- * The length of the string can go beyond the allocated size: the buffer is
- * then truncated, but the functions still keep account of the actual total

- * In other words, buf->len can be greater than buf->size and records the
- * total length of what would have been to the buffer if there had been
- * enough memory.
- *
- * Append operations do not need to be tested for failure: if a memory
- * allocation fails, data stop being appended to the buffer, but the length
- * is still updated. This situation can be tested with
- * av_bprint_is_complete().
- *
- * The size_max field determines several possible behaviours:
- *
- * size_max = -1 (= UINT_MAX) or any large value will let the buffer be
- * reallocated as necessary, with an amortized linear cost.
- *
- * size_max = 0 prevents writing anything to the buffer: only the total
- * length is computed. The write operations can then possibly be repeated in
- * a buffer with exactly the necessary size
- * (using size_init = size_max = len + 1).
- *

- * The string buffer grows as necessary and is always 0-terminated.

- * encoding-agnostic and can even hold binary data.
- *
- * Small buffers are kept in the structure itself, and thus require no
- * memory allocation at all (unless the contents of the buffer is needed
- * after the structure goes out of scope). This is almost as lightweight as
- * declaring a local "char buf[512]".
- *
- * The length of the string can go beyond the allocated size: the buffer is
- * then truncated, but the functions still keep account of the actual total
- * length.
- *
- * In other words, buf->len can be greater than buf->size and records the
- * total length of what would have been to the buffer if there had been
- * enough memory.
- *
- * Append operations do not need to be tested for failure: if a memory
- * allocation fails, data stop being appended to the buffer, but the length
- * is still updated. This situation can be tested with
- * av_bprint_is_complete().
- *
- * The size_max field determines several possible behaviours:
- *
- * size_max = -1 (= UINT_MAX) or any large value will let the buffer be
- * reallocated as necessary, with an amortized linear cost.
- *
- * size_max = 0 prevents writing anything to the buffer: only the total
- * length is computed. The write operations can then possibly be repeated in
- * a buffer with exactly the necessary size
- * (using size_init = size_max = len + 1).
- *
- * size_max = 1 is automatically replaced by the exact size available in the

- * @{
- * AVBuffer is an API for reference-counted data buffers.
- *
- * There are two core objects in this API -- AVBuffer and AVBufferRef. AVBuffer
- * represents the data buffer itself; it is opaque and not meant to be accessed
- * by the caller directly, but only through AVBufferRef. However, the caller may
- * e.g. compare two AVBuffer pointers to check whether two different references
- * are describing the same data buffer. AVBufferRef represents a single
- * reference to an AVBuffer and it is the object that may be manipulated by the
- * caller directly.
- *
- * There are two functions provided for creating a new AVBuffer with a single
- * reference -- av_buffer_alloc() to just allocate a new buffer, and
- * av_buffer_create() to wrap an existing array in an AVBuffer. From an existing
- * reference, additional references may be created with av_buffer_ref().
- * Use av_buffer_unref() to free a reference (this will automatically free the
- * data once all the references are freed).
- *
- * The convention throughout this API and the rest of FFmpeg is such that the
- * buffer is considered writable if there exists only one reference to it (and
- * it has not been marked as read-only). The av_buffer_is_writable() function is
- * provided to check whether this is true and av_buffer_make_writable() will
- * automatically create a new writable buffer when necessary.
- * Of course nothing prevents the calling code from violating this convention,
- * however that is safe only when all the existing references are under its
- * control.
- *
- * @note Referencing and unreferencing the buffers is thread-safe and thus
- * may be done from multiple threads simultaneously without any need for
- * additional locking.
- *
- * @note Two different references to the same buffer can point to different
- * parts of the buffer (i.e. their AVBufferRef.data will not be equal).

- *
- * @{
- * AVBuffer is an API for reference-counted data buffers.
- *
- * There are two core objects in this API -- AVBuffer and AVBufferRef. AVBuffer
- * represents the data buffer itself; it is opaque and not meant to be accessed
- * by the caller directly, but only through AVBufferRef. However, the caller may
- * e.g. compare two AVBuffer pointers to check whether two different references
- * are describing the same data buffer. AVBufferRef represents a single
- * reference to an AVBuffer and it is the object that may be manipulated by the
- * caller directly.
- *
- * There are two functions provided for creating a new AVBuffer with a single
- * reference -- av_buffer_alloc() to just allocate a new buffer, and
- * av_buffer_create() to wrap an existing array in an AVBuffer. From an existing
- * reference, additional references may be created with av_buffer_ref().
- * Use av_buffer_unref() to free a reference (this will automatically free the
- * data once all the references are freed).
- *
- * The convention throughout this API and the rest of FFmpeg is such that the
- * buffer is considered writable if there exists only one reference to it (and
- * it has not been marked as read-only). The av_buffer_is_writable() function is
- * provided to check whether this is true and av_buffer_make_writable() will
- * automatically create a new writable buffer when necessary.
- * Of course nothing prevents the calling code from violating this convention,
- * however that is safe only when all the existing references are under its
- * control.
- *
- * @note Referencing and unreferencing the buffers is thread-safe and thus
- * may be done from multiple threads simultaneously without any need for
- * additional locking.
- *
- * @note Two different references to the same buffer can point to different
- * parts of the buffer (i.e. their AVBufferRef.data will not be equal).

- * @defgroup avoptions AVOptions
- * @ingroup lavu_data
- * @{
- * AVOptions provide a generic system to declare options on arbitrary structs
- * ("objects"). An option can have a help text, a type and a range of possible
- * values. Options may then be enumerated, read and written to.
- *
- * @section avoptions_implement Implementing AVOptions
- * This section describes how to add AVOptions capabilities to a struct.
- *
- * All AVOptions-related information is stored in an AVClass. Therefore
- * the first member of the struct should be a pointer to an AVClass describing it.
- * The option field of the AVClass must be set to a NULL-terminated static array
- * of AVOptions. 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() can 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 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 FFmpeg 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.

- * @defgroup avoptions AVOptions
- * @ingroup lavu_data
- * @{
- * AVOptions provide a generic system to declare options on arbitrary structs
- * ("objects"). An option can have a help text, a type and a range of possible
- * values. Options may then be enumerated, read and written to.
- *
- * @section avoptions_implement Implementing AVOptions
- * This section describes how to add AVOptions capabilities to a struct.
- *
- * All AVOptions-related information is stored in an AVClass. Therefore
- * the first member of the struct should be a pointer to an AVClass describing it.
- * The option field of the AVClass must be set to a NULL-terminated static array
- * of AVOptions. 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;
- *

- * .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() can 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 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 FFmpeg 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.

- * Pixel format.
- *
- * @note
- * AV_PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
- * color is put together as:
- * (A << 24) | (R << 16) | (G << 8) | B
- * This is stored as BGRA on little-endian CPU architectures and ARGB on
- * big-endian CPUs.
- *
- * @par
- * When the pixel format is palettized RGB (AV_PIX_FMT_PAL8), the palettized
- * image data is stored in AVFrame.data[0]. The palette is transported in
- * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
- * formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is
- * also endian-specific). Note also that the individual RGB palette
- * components stored in AVFrame.data[1] should be in the range 0..255.
- * This is important as many custom PAL8 video codecs that were designed
- * to run on the IBM VGA graphics adapter use 6-bit palette components.
- *
- * @par
- * For all the 8bit per pixel formats, an RGB32 palette is in data[1] like
- * for pal8. This palette is filled in automatically by the function
- * allocating the picture.
- *
- * @note
- * Make sure that all newly added big-endian formats have (pix_fmt & 1) == 1
- * and that all newly added little-endian formats have (pix_fmt & 1) == 0.
- * This allows simpler detection of big vs little-endian.

- *
- * - The floating-point formats are based on full volume being in the range

- *
- * - The data layout as used in av_samples_fill_arrays() and elsewhere in FFmpeg
- * (such as AVFrame in libavcodec) is as follows:
- *
- * @par
- * For planar sample formats, each audio channel is in a separate data plane,
- * and linesize is the buffer size, in bytes, for a single plane. All data
- * planes must be the same size. For packed sample formats, only the first data
- * plane is used, and samples for each channel are interleaved. In this case,
