This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The metadata
property of the MediaSession
interface contains a MediaMetadata
object providing descriptive information about the currently playing media, or null
if the metadata has not been set. This metadata is provided by the browser to the device for presentation in any standard media control user interface the device might offer.
Syntax
var mediaMetadata = navigator.mediaSession.metadata; navigator.mediaSession.metadata = mediaMetadata;
Value
An instance of MediaMetadata
containing information about the media currently being played.
Example
The following example creates a new media session and assigns action handlers to it:
if ('mediaSession' in navigator){ navigator.mediaSession.metadata = new MediaMetadata({ title: "Podcast Episode Title", artist: "Podcast Host", album: "Podcast Name", artwork: [{src: "podcast.jpg"}] }); navigator.mediaSession.setActionHandler('play', function() {}); navigator.mediaSession.setActionHandler('pause', function() {}); navigator.mediaSession.setActionHandler('seekbackward', function() {}); navigator.mediaSession.setActionHandler('seekforward', function() {}); navigator.mediaSession.setActionHandler('previoustrack', function() {}); navigator.mediaSession.setActionHandler('nexttrack', function() {}); }
