+/**
+ * @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.
+ *
+ * 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 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".
+ *
+ * - 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

+ *
+ * The string buffer grows as necessary and is always 0-terminated.
+ * The content of the string is never accessed, and thus is
+ * 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
+ * structure itself, thus ensuring no dynamic memory allocation. The
+ * internal buffer is large enough to hold a reasonable paragraph of text,

+ * @{
+ * 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 options[] = {

+ * .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() 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 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.
