Would stream.clone() work in this case? I think this would be the solution now. Clone the MediaStream; attach one of the two clones to the video element and the other to the PeerConnection; put enabled=false on the track(s) in question of the MediaStream attached to the PC. Note, this does not really pause sending, but sends black frames/silence over the net. A little bit down the road the RTCRTPSender (not yet in the main branch of the spec) will be there, and it will AFAIK have a method for "stop sending this track". Then you will not have to clone. >
