sudo nvidia-modprobe -u -c=0 don't worked.

NVENC worked with me on other distributions, but I'm not getting it with openSUSE Tumbleweed.

Here are some screenshots, in case it helps.

Same problem here, on Ubuntu 20.04, nvidia drivers.

Uninstall flatpak version and install from ppa solves the issue. There is something related with packaging or permissions.

Same issue on Kubuntu 21.04. This project/package has a maintainer, hasn't it?

Maybe a duplicate of #83

I reently had a fight with this problem myself in Arch. Using NVENC requires the existence of the /dev/nvidia-uvm and /dev/nvidia-uvm-tools modules which aren't created even after loading the nvidia-uvm module. I documented what I had to do to make it work in the Arch Wiki. Maybe this info will help others facing this too.

Given this is not a bug in OBS Studio itself, nor in the Flathub package, I'll close this issue. If people file new issues with this problem but for different distros, let's increment that wiki page.
