RTCPeerConnection.removeTrack()

The RTCPeerConnection.removeTrack() method tells the local end of the connection to stop sending media from the specified track, without actually removing the corresponding RTCRtpSender from the list of senders as reported by RTCPeerConnection.getSenders(). If the track is already stopped, or is not in the connection's senders list, this method has no effect.

If the connection has already been negotiated (signalingState is set to "stable"), it is marked as needing to be negotiated again; the remote peer won't experience the change until this negotiation occurs. A negotiationneeded event is sent to the RTCPeerConnection to let the local end know this negotiation must occur.

Syntax

pc.removeTrack(sender);

Parameters

sender

A RTCRtpSender specifying the sender to remove from the connection.

Return value

undefined.

Exceptions

InvalidStateError

The connection is not open.

Example

This example adds a video track to a connection and sets up a listener on a close button which removes the track when the user clicks the button.

var pc, sender;
navigator.getUserMedia({video: true}, function(stream) {
  pc = new RTCPeerConnection();
  var track = stream.getVideoTracks()[0];
  sender = pc.addTrack(track, stream);
});

document.getElementById("closeButton").addEventListener("click", function(event) {
  pc.removeTrack(sender);
  pc.close();
}, false);
