Flatpak apps not seeing webcam


I’ve added the v4l2 kernel module and and v4l-util package to make the virtual webcam work with obs/ffmpeg, and it’s able to pipe it to /dev/video0, but flatpak apps cannot access it despite having permission to devices=all, which works on other distros. It’s especially weird because OBS is a flatpak and it’s able to pipe video.

Can someone test it if it’s just me?

Here is my config.
