-/**
- * @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 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.
- *
- * The packet data belongs to the demuxer and is invalid after the next call to
- * av_read_frame(). The user must free the packet with av_free_packet() before
- * calling av_read_frame() again or closing the file.

- * @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 Libav,
- * 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".

- @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.

- * @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 must 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 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     = 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);
- * }

- *
- * @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.

- * For planar sample formats, each audio channel is in a separate data plane,
