I think there's a problem here.  A MediaController (and a webrtc::Call) is a
per-PeerConnection object.  But a PeerConnectionFactory (and a ChannelManager)
is a cross-PeerConnection object.

Instead of factory->media_controller(), we should maybe have
factory->CreateMediaController().

Yes, sorry about that... I must have stopped thinking.

   // External Video encoder factory. This can be NULL if the client has not
   // injected any. In that case, video engine will use the internal SW encoder.
