video.js – How to play webrtc playback in VideoJs

I have tried two use cases to play webrtc playback on videojs.

After getting MediaStream from webrtc and add like the following:

player.src({src:webRTCAdaptor.remoteVideo.srcObject});

I’m getting (CODE:4 MEDIA_ERR_SRC_NOT_SUPPORTED) error.
If i do like following, I’m not getting any error but video does not play either.

var vid=player.tech().el();
vid.srcObject=webRTCAdaptor.remoteVideo.srcObject;

Calling player.play() doesn’t change anything.

Does anybody has any insight about it?
