The MediaMetadataRetriever <https://developer.android.com/reference/android/media/MediaMetadataRetriever> class "provides a unified interface for retrieving frame and meta data from an input media file." Its extractMetadata(int) <https://developer.android.com/reference/android/media/MediaMetadataRetriever#extractMetadata(int)> function allows the developer to retrieve the metadata value associated with a METADATA_KEY_XXX <https://developer.android.com/reference/android/media/MediaMetadataRetriever#constants_1> constant specified in the same class. I propose to add some new *METADATA_KEY_XXX* constants to the class and the ability to extract the value of these keys from metadata tags.
The proposed constants are: METADATA_KEY_ARTIST_MBID METADATA_KEY_RECORDING_MBID METADATA_KEY_ALBUM_MBID METADATA_KEY_RELEASEGROUP_MBID These constants represent the MusicBrainz Identifiers for the corresponding entities. There are a number of reasons why MusicBrainz Identifiers should be included. MusicBrainz <https://musicbrainz.org/doc/About> is a community-maintained open source encyclopedia of music information. A MusicBrainz Identifier <https://musicbrainz.org/doc/MusicBrainz_Identifier> (MBID) is a 36 character Universally Unique identifier that is permanently assigned to an entity. MusicBrainz Identifiers provide a reliable and unique way to identify music. Often, Media files have incomplete metadata. But if the media file is tagged with an MBID, developers can use it to retrieve a comprehensive set of information about the media. This has potentially many use cases, including but not limited to, library organising apps, music players, music recommenders and trivia apps. Since, no two different media files have the same the MBID, developers can use it to find duplicate media files. The iOS ecosystem already has some kind of support for MBIDs. Apple's iTunes has out of the box support for using MBIDs. Popular search engines including Google and Bing utilise MBIDs to populate knowledge graphs about the relevant entities. A detailed list of MusicBrainz Enabled Applications can be found here <https://musicbrainz.org/doc/MusicBrainz_Enabled_Applications>. Many other prominent entities <https://metabrainz.org/supporters> in the technology landscape support and utilise MusicBrainz services as well. I am willing to contribute the required code changes myself. I wish to know the views of other developers regarding this feature request. -- You received this message because you are subscribed to the Google Groups "Android Discuss" group.
