Janus provides a mechanism for every plugin related to PeerConnection to report its status externally. Why is there a failure to receive webrtcup and media?
I’m sorry but I don’t understand the question.
The process of constructing peerconnection is not stable. Sometimes, I could receive responses about webrtcup and media, and pushing the stream to remote. but the other time, it is a failure to receive them. I am not sure what happened.
Use the browser’s webrtc internals and the Janus Admin API to figure out the problem, very likely an ICE issue.
