logic to swap small container with full screen video

.js

var containerId = '#' + streamId + '_container';
$(containerId).dblclick(function() {
  // play selected container as full screen - swap out current full screen stream
  remoteStreams[mainStreamId].stop(); // stop the main video stream playback
  addRemoteStreamMiniView(remoteStreams[mainStreamId]); // send the main video stream to a container
  $(containerId).empty().remove(); // remove the stream's miniView container
  remoteStreams[streamId].stop() // stop the container's video stream playback
  remoteStreams[streamId].play('full-screen-video'); // play the remote stream as the full screen video
  mainStreamId = streamId; // set the container stream id as the new main stream id
});
