Freeze WebRTC video stream and keep audio stream running -

is possible in webrtc freeze video stream , keep audio stream running @ same time?

by freezing video mean stop refreshing video input time, keeping last captured frame until flag webrtc unfreeze.

from discussion on google groups, appears set individual video stream's enabled property false (likewise audio muting):

// assuming `remotestream` on other end remotestream.getvideotracks()[0].enabled = false; 

note may blank out video, rather using last captured frame.
