Hey @tylerlong

I just released pion/webrtc@v3 would you be open to accepting a PR upgrading this repo to v3?

I also can add a demo of sending audio as well (and not just playing) we created pion/mediadevices that shows how to capture microphone/webcam in Go.

thanks!

I am working on it. But I encountered some issue.

@Sean-Der Appreciate if you could give me some advice.

I think it might be caused by the ICE server configuration.

Source code is here https://github.com/ringcentral/ringcentral-softphone-go/tree/dev (dev branch instead of master branch)

Output is here:

Hey @tylerlong thanks for doing the upgrade, I am not exactly sure yet. Here are the things I am thinking.

  • 100.64.0.1:59839-> I am guessing that is an interface for Docker or some kind of LAN that can't route packets? So that should be fine.
  • Pion isn't controlling so we are waiting on the server to send us ICE traffic.
  • Is it possible Pion isn't meant to be the controlling ice-agent? Try adding a=ice-lite, lots of WebRTC servers run ice-lite
  • Can you set PION_LOG_TRACE=ice and see what that gives you? I am curious if the server is sending anything.
  • pingAllCandidates called with no candidate pairs this happens if we have no remote candidates. Since it stopped that is good, means we have at least one remote candidate!

@Sean-Der in master branch there is the pion/webrtc/v2 version https://github.com/ringcentral/ringcentral-softphone-go/blob/master/answer.go

And it worked (not sure it works now but it used to work). So I am wondering what I did wrong in pion v3. I mean if I upgrade everything correctly it should just work. So it's kind of a pion upgrade question.

I am reading your list of things and I am trying. I will post update later. Thanks again.

First I would turn off trickle ICE. That is the only difference I know of.

change the code here to be

        gatherComplete := webrtc.GatheringCompletePromise(peerConnection)
	err = peerConnection.SetLocalDescription(answer)
	if err != nil {
		panic(err)
	}
        <-gatherComplete

The instead of answer.SDP do peerConnection.SetLocalDescription(answer).SDP here

can you put a=ice-lite before m=audio in the global section.

Pion finds lots of valid candidate pairs ice TRACE: 18:55:36.099153 selection.go:231: Found valid candidate pair: prio 9151314440652587007 (local, prio 2130706431) udp4 host 192.168.1.118:57183 <-> udp4 host 199.255.120.232:47226 (remote, prio 2130706431)

But then it is waiting for the server to select one (and it never happens). if you put a=ice-lite that makes Pion the controlling agent.

  • Maybe we are losing the use-candidate
  • Maybe we are selecting our role incorrectly
  • Maybe our ICE Agent should select a candidate pair on a timeout?

I am not sure :/

The very first error/warning is

ice WARNING: 2021/02/19 18:55:36 failed to resolve stun host: 74.125.194.127:19302: address 74.125.194.127: no suitable address found

What does it mean? The subsequent errors may be caused by this one.

@tylerlong webrtc.GatheringCompletePromise and ice-lite didn't help? If you can email me repro to [email protected] I love to help also :)

failed to resolve stun host: is non-fatal. It loops all your interfaces and sends a STUN request. You may have multiple public IPs so trying to figure them all out. That shouldn't be a problem! I can look into making a note this is non-fatal in the log message :)

I have made some change bb9d78d
The phone call was answered but I didn't see the audio data coming in. OnTrack never triggered.

I will email your the credential so that you can run the code on your local computer.
