Users can't see each other webcams #13931

Closed prudloff-insite closed 10 months ago

Description:

We are self-hosting Jitsi Meet and we often get a bug where someone will enable their camera and nobody else will see it. (To others it appears as if the user does not have their camera enabled.)

I think it started to happen when we upgraded from 2.0.8719-1 to 2.0.8922-1 (or at least it was not this frequent before).

Steps to reproduce:

  1. Say you have a room with 2 users.
  2. User A enables their camera.
  3. User B does not see it.

This has been confirmed by several of our users.

(I tried to reproduce on https://meet.jit.si/ but got a different bug: as soon as I enabled my camera, audio and video froze for both me and the other user.)

Expected behavior:

When an user enables their camera, the other users should see it.

Actual behavior:

Very often, other users don't see the camera.

Server information:

Client information:

Additional information:

Here is a browser log from the user enabling their camera (Firefox on Linux): Jitsi-camera-sender-logs.txt

And from the other user (Firefox on Linux): Jitsi-camera-receiver-logs.txt

prudloff-insite commented 10 months ago

We updated jitsi-meet to 2.0.9111-1 and we can still reproduce the problem.

We noticed that if user B enables their camera, then they start seeing user A's camera.

Did you configure startWithAudioOnly by any chance?

Do you mean startAudioOnly? Yes we it is enabled in our config:

This is how audioOnly works. All users are in audio only mode and when they enable video they get out of audio only mode and start receiving video.

Please, when you have questions or problems use the community forum before opening new issues, thank you.

This is a bit confusing and really looked like a bug. I thought the option only meant that users had their camera disabled by default (we enabled that because we were not using prejoin before, so we did not we want users to be surprised that their webcam was enabled).

I confirm that setting startAudioOnly to false fixes the problem. I think it would be better if Jitsi could display a message explain to the user that they are in audio only mode and can't see cameras.

There is an indicator with the letters AUD that domains on hover.

As the system administrator it's you who needs to understand what options you set in config, IIRC the config.js sample is pretty clear.
