Camera won't work

[ItachiSan]

Hi, I am having issues with the camera.

I've tried testing the camera via User settings > Voice & Video > Video > Test video and never works.
I've enabled newer camera support via WebRTC; I am unsure what is not working.

I would like to know a case where the webcam works so I can reproduce it.
I am on Arch and I use this package: https://aur.archlinux.org/packages/discord-electron-openasar

Please let me know what feedback I can provide and which tests to run.
Thanks in advance!

Stacktrace from this crash (tested with webcam, but I assume it hits the same function with streams):

[ItachiSan]

Did some investigation and found stuff.

So, I mainly used Discord repackaged for system Electron and OpenAsar, namely this AUR package on Arch:
https://aur.archlinux.org/packages/discord-electron-openasar

It seems that the window.createDiscordStream is a sync version of the getUserMedia() function.
That is built in the official Discord Electron.

In short, using OpenAsar with the official Discord tar release with custom Electron works, while using system Electron won't.
