Problem

  • IOS sdk emulate packet loss 100%, then recover network 30 seconds after,  two same offers sent before packet loss and after network recover.
  • webrtc-agent crash if webrtc-agent received 'offer' twice in same wrtcConnection

Reason

  1. wrtcConnection.setupTransport method will called twice
       2. setupTransport will new FramePacketizer twice, and the two FramePacketizer using same 'MediaStream' instance
