title: the event firing with track.stop() function
body: <p>i want to stop sharing my video call and i use the <code>peerConnection.removeStream(localStream);</code> function with the event  <code>onremovestream</code> but i find that it's deprecated and then the <code>onremovestream</code> doesn't fired anymore,i tried  to use the <code>track.stop()</code> function like this :</p>
  
  <pre><code> var videoTracks = localStream.getVideoTracks();
      videoTracks.forEach(function(track) {
      track.stop();
      }); 
  </code></pre>
  
  <p>now i want to know the event fired with that function to know when the video call is stopped in the remote peer .
