VideoTrack: id property

Limited availability

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

The id property contains a string which uniquely identifies the track represented by the VideoTrack.

This ID can be used with the VideoTrackList.getTrackById() method to locate a specific track within the media associated with a media element.

The track ID can also be used as the fragment of a URL that loads the specific track (if the media supports media fragments).


A string which identifies the track, suitable for use when calling getTrackById() on an VideoTrackList such as the one specified by a media element's videoTracks property.
