RTCSessionDescription()

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.

Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

The RTCSessionDescription() constructor creates a new RTCSessionDescription.

Syntax

 sessionDescription = new RTCSessionDescription(rtcSessionDescriptionInit);

Values

rtcSessionDescriptionInit Optional
Is a RTCSessionDescriptionInit dictionary, having the following fields:
  • "type", optional and defaulting to null, of type RTCSdpType, that is "offer", "answer" or "pranswer".
  • "sdp", optional and defaulting to null, of type DOMString and containing a SDP message describing the session.

Example

navigator.getUserMedia({video: true}, function(stream) {
  pc.onaddstream({stream: stream});
  // Adding a local stream won't trigger the onaddstream callback
  pc.addStream(stream);

  pc.createOffer(function(offer) {
    pc.setLocalDescription(new RTCSessionDescription(offer), function() {
      // send the offer to a server to be forwarded to the friend you're calling.
