RTCTrackEvent()

The RTCTrackEvent() constructor creates and returns a new RTCTrackEvent object, configured to describe the track which has been added to the RTCPeerConnection.

In general, you won't need to use this constructor, as RTCTrackEvent objects are created by WebRTC and delivered to your RTCPeerConnector's ontrack event handler as appropriate.

eventInfo

receiver

streams Optional

An array of MediaStream objects representing each of the streams that comprise the event's corresponding track.

track

The MediaStreamTrack the event is associated with.

transceiver

The RTCRtpTransceiver associated with the event.
