Like all strings in Libav, + * metadata must be stored as 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 -- . + 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.

Like all strings in Libav, - * metadata must be stored as 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 -- . - 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.
