WebRTC view not work but the png view working

[maithanhtan]

Hi Team, I am trying to find why my webrtc view not working: It show connected when login with white screen. Afew second later it show Disconnected state with dark screen. From browser console log I did not find anything abnormal

Can you please help to guide how to troubleshoot this case.

FYI: the png view is working so i think the emulator if work. there something wrong for the webrtc view only

Thank you

This is most likely a networking issue. Could you share the docker logs. Only the lines starting with: "video:" are of importance.

emulator_1 | video: (network.cc:929): Connect failed with 99 emulator_1 | video: (video_stream_encoder.cc:1317): Number of frames: captured 204, dropped (due to congestion window pushback) 0, dropped (due to encoder blocked) 0, interval_ms 60000

The 'Connect failed with 99' is a red herring. The page: chrome://webrtc-internals/ in chrome will show debug information about WebRTC connections that are being established.

I am having the same issue. chrome://webrtc-internals does not give much information, it just says the connection failed

Same issue, latest master branch w/ Firefox 93.0 64 bits on Linux

error in firefox console is:

WebRTC: ICE failed, add a STUN server and see about:webrtc for more details

the client and the server are remote and connected through a VPN. Maybe that is the issue

[chgans]

The problem is that the remote candidate is the internal docker IP address (eg 10.x.y.z) instead of the machine's IP. I tried to setup a TURN server as per https://source.android.com/devices/automotive/start/avd/cloud_emulator#troubleshooting, but the web page is still trying to connect to the docker IP address, not the server public address

After fixing a typo, it is now working using coturn! :)
