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.

Syntax

trackEvent = new RTCTrackEvent(eventInfo);

Parameters

eventInfo
An object based on the RTCTrackEventInit dictionary, providing information about the track which has been added to the RTCPeerConnection. This object has the following properties:
receiver
The RTCRtpReceiver which is being used to receive the track's media.
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.

Return value

A new RTCTrackEvent describing a track which has been added to the RTCPeerConnection.
