Mediasoup-demo not working with iceTransportPolicy relay

mediasoup-demo
1

First of all kindly thanks for your great effort on mediasoup
I have an issue with mediasoup-demo and turn as following, any help is welcome

Your environment

  • Operating system: macOS
  • Node version: 12.19.0
  • npm version: 6.14.8
  • gcc/clang version: 12.0.0
  • mediasoup version: 3.6.25
  • mediasoup-client version: 3.6.21

Issue description

  • Tested using mediasoup-demo repo, also in our private mediasoup app
  • Without iceTransportPolicy, the demo work well
  • When using iceTransportPolicy relay to force using turn, the remote video is black/empty
  • With the same iceTransportPolicy and iceServers, raw webrtc implementation works well, so we have a conclusion that problem may come from mediasoup

Coturn /etc/turnserver.conf

tls-listening-port=443

You may have an IP routing problem between client and TURN server or between TURN and mediasoup server.

Hi, I have tested as following:

  • I create a raw webrtc with simple socket io, run on my local machine with iceServers and iceTransportPolicy to force using turn, that raw webrtc demo work well (I always look at the chrome://webrtc-internals to see and confirm the relay candidate). So I guess connection between turn server and my local machine is OK.
  • For mediasoup-demo I clone the repo, then modify transport config with the same above config, then run on my local machine. But couldnt see the remote video.

So as you suggest there may be an issue routing, but sadly I dont know how to debug and findout the solution. Could change the port range of mediasoup help it?

Please don’t try random things. Ensure that the listen and/or announced IP in the mediasoup WevRtcTransport can talk to the IP that TURN uses for relaying. There is a setting for that in the TURN server.

And instead of “video is not shown” please focus on transport.connectionState in mediasoup-client and transport.iceState in server side. There are also events for them.

I hope this will help. O cannot help much more.

Thanks for your great support, we have figured out the root cause. One of our engineer set forceTcp=true in the code and it cause the demo failed with turn relay.

After remove it, issue resolved.
