On client side, look into the stream status listeners:
Code:
session.on(STREAM_STATUS.PLAYING, function(previewStream){
// Video is being received. It should be playing
}).on(STREAM_STATUS.STOPPED, function(){
// Stream not playing
}).on(STREAM_STATUS.FAILED, function(){
// Stream issue
}
}).play();
Do you see status PLAYING on browser?
If you see status PLAYING and no video, it can be a bug.
If you can reproduce this, please provide debug logs. We will check.
