994277 - webrtc video broken in Linux

Status: RESOLVED INCOMPLETE

(Core :: WebRTC, defect)

Description

[Hubert Figuiere [:hub]]

I have mozilla central here on Linux Fedora 20.

If I connect to a room on https://appear.in, I don't get my own video feed. If I connect to the same room on the Mac running Nihgtly, I get both the Mac video feed and the Linux video feed (ie the webcam to work)

Not problem with sound.

In that case both machine are on the same LAN.

Does it prompt you for access to the camera?

Are you saying the Mac person sees the Linux person, and the problem is limited to self-view on linux?

To make sure this isn't a bug in appear.in , please report if these work on your linux box:

- http://mozilla.github.io/webrtc-landing/pc_test.html (local short-circuit test)
- http://apprtc.appspot.com/

Thanks.

It sure does. And it sure sends it to the other side.

To any view. Mac client sees both. Linux client sees none.

Both work. So it is possible it be an appear.in bug. But only on Linux.

Looks like it. I would give them a ping and we should probably close this bug.

On my (win<->mac) test-call using appear.in I noticed that un-mute video didn't work (remote side lost video for good), so they're probably still fixing bugs.

Note the first thing to suspect is not OS issues, but lack-of-TURN-server issues, especially if connecting from Mozilla offices (symmetric firewalls).  Capture about:webrtc (Select All, Save As), perhaps with the logging open and attach (from both ends).  The call needs to still be open.

I tried it locally (which means not going through a firewall) and it works.

I am not in any Mozilla office - just at home. Also the Mac had no problem in that case and it is on the exact same LAN as the Linux machine (the same desk actually ;-) )

If this is still an issue, please reopen and attach logs.

No idea, I have nobody to try this with.
