MediaMetadata

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The MediaMetadata interface of the Media Session API allows a web page to provide rich media metadata for display in a platform UI.

Constructor

MediaMetadata(): Creates a new MediaMetaData object.

Instance properties

MediaMetadata.album: Returns or sets the name of the album or collection containing the media to be played.
MediaMetadata.artist: Returns or sets the name of the artist, group, creator, etc. of the media to be played.
MediaMetadata.artwork: Returns or sets an array of images associated with playing media.
MediaMetadata.chapterInfo Read only Experimental: Returns an array of chapter information metadata associated with playing media, represented by ChapterInformation object instances.
MediaMetadata.title: Returns or sets the title of the media to be played.

  navigator.mediaSession.metadata = new MediaMetadata({
