What happened?

i got this error "Incoming unhandled RTP ssrc(XXXXXXX), OnTrack will not be fired. incoming SSRC failed Simulcast probing" with version 3.x i tried v4.0.0.beta9 then i got "Incoming unhandled RTP ssrc(XXXXXXX), OnTrack will not be fired, EOF"

Same problem.

Same issue here.

I've first got this error Incoming unhandled RTP ssrc(xxxxxxx), OnTrack will not be fired. mid RTP Extensions required for Simulcast with version 3.x.

Then I tried to upgrade to version 4.x and now I'm getting Incoming unhandled RTP ssrc(xxxxxxxxx), OnTrack will not be fired. EOF

I added a server per protocol and it fixed the problem in the backend. Now the frontend is struggeling with getting the trackID.

webrtcCfg := webrtc.Configuration{
SDPSemantics: webrtc.SDPSemanticsUnifiedPlanWithFallback,
ICEServers: []webrtc.ICEServer{
    {
        URLs: []string{
            "stun:stun.l.google.com:19302",
        },
    },
    {
        URLs: []string{
            "stun:stun.l.google.com:443?transport=udp",
            "stun:stun.l.google.com:443?transport=tcp",
        },
    },
}}

I will investigate tonight. Chrome has changed behavior in the latest release.

Pion might have an existing bug that is getting exposed. I will share more when I have answers

shsma commented 6 months ago

True that. I started seeing this problem after updating chrome.

yangxingyu commented 6 months ago

This is a great project. I have been studying the code recently and I appreciate your work.

shsma commented 6 months ago

@Sean-Der Any updates!

Sean-Der commented 6 months ago

This has been fixed with https://github.com/pion/webrtc/commit/92df4bf0ec6d401827a6dbaa5b8be6d4d4a6a3d3

Please update to v4.0.0-beta.15 or v3.2.32. A workaround exists and was added to Pion. See https://issues.chromium.org/u/1/issues/328522463?pli=1
