Here is another screen cast, https://filebin.net/izr4g99jp4ry9zfd

I increased PLI interval up to 20 seconds. From video you can see that after muting video track still sends packets before getting the new PLI request.

I checked media track state, it has only one changed property - 'enabled = false', also checked RTCRtpSender with getSenders() - there are two senders before and after muting - sender with audio track and sender with video track. 

WebRTC logging shows that webrtc stack sends black frame, but no packets on outbound connection.
