06/30/2023, 8:30 PMDo I need to react to the server telling the publisher to mute? whats the expected behaviour

06/30/2023, 9:07 PMAlso, how is the connection quality metric computed? I'm getting a bad quality even on local network

06/30/2023, 10:13 PMfor mute, you can pause publishing. the server would have already marked it as muted to avoid forwarding to other clients

06/30/2023, 10:15 PMas for connection quality, it's likely due to:
ā¢ publisher not sending the right simulcast layers (for example, if it's signaling 3 layers, but only pushing bits for 1). This typically indicates congestion on the publisher's side
ā¢ packet losses (could be coming from unhandled NACKs)

06/30/2023, 10:27 PMWhat are you expecting on nack? I'm not sending any layers in the addtrackrequest (webrtcsink doesn't have simulcast support yet)

06/30/2023, 10:28 PMWhat does pause publishing mean? Change the direction of the stream to inactive in an sdp update? Or just stop sending media packets?

06/30/2023, 10:28 PMthe latter - just stop sending packets. (it'll just use a bit more bandwidth if left alone, which is also fine)

06/30/2023, 10:29 PMon NACK, we expect the same packets to be retransmitted with the same SSRC. This will be an issue over the internet, but I'm not confidence this is the issue since you are testing over localhost

06/30/2023, 10:30 PMif you can send me the server logs, I can take a look!
