Check the Browser compatibility table carefully before using this in production.
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. Avoid using it and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
The RTCPeerConnection.onaddstream
event handler is a property containing the code to execute when the addstream
event, of type MediaStreamEvent
, is received by this RTCPeerConnection
. Such an event is sent when a MediaStream
is added to this connection by the remote peer. The event is sent immediately after the call setRemoteDescription()
and doesn't wait for the result of the SDP negotiation.
This property has been removed from the specification; you should now use RTCPeerConnection.ontrack
to watch for track
events instead. It is included here in order to help you adapt existing code and understand existing samples, which may not be up-to-date yet.
RTCPeerConnection.onaddstream = eventHandler;
This property is a function which handles addstream
events. These events, of type MediaStreamEvent
, are sent when streams are added to the connection by the remote peer. The first time an event occurs may be nearly immediately after the remote end of the connection is set using RTCPeerConnection.setRemoteDescription()
; it doesn't wait for a particular stream to be accepted or rejected using SDP negotiation.
This code, based on an older version of our Signaling and video calling sample, responds to addstream
events by setting the video source for a <video>
element to the stream specified in the event, and then enabling a "hang up" button in the app's user interface.
pc.onaddstream = function(event) { document.getElementById("received_video").srcObject = event.stream; document.getElementById("hangup-button").disabled = false; };
