Note: This method has been deprecated; you should, compatibility allowing [2], switch to using the addTrack() method instead.
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.
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.addStream() method adds a MediaStream as a local source of audio or video. If the negotiation already happened, a new one will be needed for the remote peer to be able to use it.
If the signalingState is set to "closed", an InvalidStateError is raised. If the signalingState is set to "stable", the event negotiationneeded is sent on the RTCPeerConnection.
Syntax
pc.addStream(mediaStream);
Parameters
mediaStream- A
MediaStreamobject indicating the stream to add to the WebRTC peer connection.
Return value
None.
Example
navigator.getUserMedia({video:true, audio:true}, function(stream) {
var pc = new RTCPeerConnection();
pc.addStream(stream);
});
