Received REMB for packet feedback only GoogCC

mediasoup libraries

mediasoup v3.5.5
meidasoup-client v3.3.12

In my own program, I only get the audio stream through navigator.mediaDevices API, and then follow Communication Between Client and Server to make calls.

The call can be connected or ended normally. During the call, one party is normal, but the other party only has video and cannot hear sound.

I don’t know why it happend:

Do both sides of the call have to have video and audio streams?

Which browsers? In which browser does it happen? Please provide much more info.

No.

Chrome 80.0.3987.149

I just checked it out. I’m roll back mediasoup to 3.4.6 to solve the problem.

I didn’t read the relevant updates, which may be caused by version 3.5.x update.

The following log also appeared in my mediasoup

mediasoup:ERROR:Channel [pid:99915 webrtc::GoogCcNetworkController::OnRemoteBitrateReport() | Received REMB for packet feedback only GoogCC +89ms
...
mediasoup:ERROR:Channel [pid:99915 webrtc::GoogCcNetworkController::OnRemoteBitrateReport() | Received REMB for packet feedback only GoogCC +532ms

My video playback is normal. Do I need to pay attention to these logs?
