This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
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 notificationneeded
event is sent to the RTCPeerConnection
to let the local end know this negotiation must occur.
Syntax
pc.removeTrack(sender);
Parameters
mediaTrack
- A
RTCRtpSender
specifying the sender to remove from the connection.
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);

[1] Firefox currently removes the RTCRtpSender
from the list of senders as reported by RTCPeerConnection.getSenders()
. This was correct in earlier versions of the specification, but no longer is. See bug 1290949.
