TrackEvent class

The interface, which is part of the HTML DOM specification, is used for events which represent changes to a set of available tracks on an HTML media element; these events are addtrack and removetrack. It's important not to confuse with the RTCTrackEvent interface, which is used for tracks which are part of an RTCPeerConnection. Events based on are always sent to one of the media track list types:

Events involving video tracks are always sent to the VideoTrackList found in HTMLMediaElement.videoTracks Events involving audio tracks are always sent to the AudioTrackList specified in HTMLMediaElement.audioTracks Events affecting text tracks are sent to the TextTrackList object indicated by HTMLMediaElement.textTracks.
