Linux Version Cannot Detect Webcam

[CaliberDied]

For some reason the software doesn't seem to be able to detect my webcam anymore. I tested the webcam with other software, including the online web app, and it gets detected and works perfectly fine. However, using the standalone downloaded version, the webcam can't be detected. When entering streamer mode, there was a sound prompt, and the upper left hand corner said [Cancelled]. The same message occurs when trying to configure the webcam or VMC protocol.

Sounds like a permission issue. Click "DevTools" on app menu (usually on the top right or lower right of your OS, depending on what version of Linux you use), choose "Console" and see if there is any error message related to webcam.

EDIT: It works perfectly fine on version 0.16.2 just not any version thereafter

Can you provide a log that shows only the messages on the console tab? Some expected messages seem to be missing. When you try to activate a webcam, there should be some messages logged in console no matter it succeeds or not.

There is a major electron version change after v0.16.2, though it shouldn't affect Linux AFAIK

Also having this issue on linux. since 16.2 every new version will sometimes run correctly once then never again. Even unpacking a new copy does nothing.

Did some further testing. It seems things break with each electron update. I just tried 17 and 18.0 again. They did not work when originally released but they do now. all versions 19.0 and after do not.

@CaliberDied When you choose "Webcam/Media", does it show a message saying "No camera is available on this device. Drop a local media file as input instead."? Or does it simply show/do nothing with just the "Canceled" message on the top left?

There is a sound prompt, but no message at all. The Cancelled message only displayed after choosing another option i.e. Streamer Mode. Otherwise, there is no message at all.

Judging from your log file, I wonder if it's actually a WebGL-related error that prevents the speech bubble menu from being displayed. Did you see any speech bubble menu when you double-click "Webcam/Media" or basically any item on the bottom menu?

Not that I can see, no.

So this may actually be a WebGL/GPU driver issue instead of webcam. The speech bubble (2D sprite in 3D context) fails to load for some unknown reasons. This may have something to do with the following issue.

electron/electron#40684

It may have something to do with caching. Try the following and see if it helps.

$ rm -rf ~/.config/Electron/
