HTMLMediaElement: videoTracks property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The read-only videoTracks
property on HTMLMediaElement objects returns a
VideoTrackList object listing all of the VideoTrack
objects representing the media element's video tracks.
The returned list is live; that is, as tracks are added to and removed from the media element, the list's contents change dynamically. Once you have a reference to the list, you can monitor it for changes to detect when new video tracks are added or existing ones removed. See VideoTrackList events to learn more about watching for changes to a media element's track list.
Value
A VideoTrackList object representing the list of video tracks included
in the media element. The list of tracks can be accessed using array notation, or using
the object's getTrackById() method.
Each track is represented by a VideoTrack object which provides
information about the track.
