Re: active speaker information in mixed streams

+1 for an API that retrieves the CSRC list of a receiving track (so
the app could, somehow, map those SSRC values to a list of
participants obtained by other means).

In fact, it should be an event within the MediaStreamTrack that may
fire every N seconds (when incoming RTP packets include a CSRC field):

MediaStreamTrack.oncsrc =  function(sequence<ssrc>) {}
