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). - * - * @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 frames which belong a single - * elementary stream. In 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. - * - * 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 - * - * @section lavf_decoding_seek Seeking - * @} - * - * @defgroup lavf_encoding Muxing - * @{ - * @} - * - * @defgroup lavf_io I/O Read/Write - * @{ - * @} - * - * @defgroup lavf_codec Demuxers - * @{ - * @defgroup lavf_codec_native Native Demuxers - * @{ - * @} - * @defgroup lavf_codec_wrappers External library wrappers - * @{ - * @} - * @} - * @defgroup lavf_protos I/O Protocols - * @{ - * @} - * @defgroup lavf_internal Internal - * @{ - * @} - * @} - * - */ - -#include <time.h> -#include <stdio.h> /* FILE */ -#include "libavcodec/avcodec.h" -#include "libavutil/dict.h" -#include "libavutil/log.h" - -#include "avio.h" -#include "libavformat/version.h" - -struct AVFormatContext; - - -/** - * @defgroup metadata_api Public Metadata API - * @{ - * @ingroup libavf - * The metadata API allows libavformat to export metadata tags to a client - * application when demuxing. 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". - * - * - 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 - * - * Look in the examples section for an application example how to use the Metadata API. - * - * @} - */ - -#if FF_API_OLD_METADATA2 -/** - * @defgroup old_metadata Old metadata API - * The following functions are deprecated, use - * their equivalents from libavutil/dict.h instead. - * @{ - */ - -#define AV_METADATA_MATCH_CASE AV_DICT_MATCH_CASE -#define AV_METADATA_IGNORE_SUFFIX AV_DICT_IGNORE_SUFFIX -#define AV_METADATA_DONT_STRDUP_KEY AV_DICT_DONT_STRDUP_KEY -#define AV_METADATA_DONT_STRDUP_VAL AV_DICT_DONT_STRDUP_VAL -#define AV_METADATA_DONT_OVERWRITE AV_DICT_DONT_OVERWRITE - -typedef attribute_deprecated AVDictionary AVMetadata; -typedef attribute_deprecated AVDictionaryEntry AVMetadataTag; - -typedef struct AVMetadataConv AVMetadataConv; - -/** - * Get a metadata element with matching key. - * - * @param prev Set to the previous matching element to find the next. - * If set to NULL the first matching element is returned. - * @param flags Allows case as well as suffix-insensitive comparisons. - * @return Found tag or NULL, changing key or value leads to undefined behavior. - */ -attribute_deprecated AVDictionaryEntry * -av_metadata_get(AVDictionary *m, const char *key, const AVDictionaryEntry *prev, int flags); - -/** - * Set the given tag in *pm, overwriting an existing tag. - * - * @param pm pointer to a pointer to a metadata struct.
