Usually that warning is benign, as it comes up when for example the other side sends you ICE candidates for the RTCP component, but both sides agreed already to use rtcp-mux instead. Especially when ICE succeeds I think it’s pretty safe to ignore the warning. > > ICE is succeeded, but there's no incoming video for anyone there. > > What do these message mean ?

I think with ICE succeeded this is more likely a RTP transport issue, for example missing I frame or something like that. Just to be clear: the other participants saw you, but you couldn’t see any of the other participants? Can you still go back to about:webrtc <about:webrtc> and check what the RTP stats tell you in regards to receiving RTP? What Firefox version and OS are you on? Best Nils Ohlmeier
