/**
* \defgroup libavf libavformat
* 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).
* 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
* input/output formats using the av_demuxer_iterate / av_muxer_iterate() 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
* It is possible to configure lavf 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.
*
* \section urls
* URL strings in libavformat are made of a scheme/protocol, a ':', and a
* scheme specific string. URLs without a scheme and ':' used for local files
* are supported but deprecated. "file:" should be used for local files.
*
* It is important that the scheme string is not taken from untrusted
* sources without checks.
*
* Note that some schemes/protocols are quite powerful, allowing access to
* both local and remote files, parts of them, concatenations of them, local
* audio and video devices and so on.
*
* \{
*
* \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, which
* is passed to avformat_open_input(), as in the following code:
*
{@code
* const char *url = "file:in.mp3";
* AVFormatContext *s = NULL;
* int ret = avformat_open_input(&s, url, NULL, NULL);
* if (ret < 0)
* abort();
* }
* 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:
*
* 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();
* }
* }
*
* 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_send_packet() 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_packet_make_refcounted() will ensure that
* the data is reference counted, copying the data if necessary.
* In both cases, the packet must be freed with av_packet_unref() 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.codecpar "stream codec parameters" information, such as the
* codec \ref AVCodecParameters.codec_type "type", \ref AVCodecParameters.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).
* - It is advised to manually initialize only the relevant fields in
* AVCodecParameters, rather than using \ref avcodec_parameters_copy() during
* remuxing: there is no guarantee that the codec context values remain valid
* for both input and output format contexts.
* - 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().

*
* Some of possible use cases:
* - an "open file" dialog to choose files from a remote location,
* - a recursive media finder providing a player with an ability to play all
* files from a given directory.
*
* \subsection lavf_io_dirlist_open Opening a directory
* At first, a directory needs to be opened by calling avio_open_dir()
* supplied with a URL and, optionally, ::AVDictionary containing
* protocol-specific parameters. The function returns zero or positive
* integer and allocates AVIODirContext on success.

* repeatedly calling avio_read_dir() on it. Each call returns zero or
* positive integer if successful. Reading can be stopped right after the
* NULL entry has been read -- it means there are no entries left to be
* read. The following code reads all entries from a directory associated

* \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:
*
