There seems to be some builds on arch that are working fine but I haven't tried these. What is did was installing latest git (obs-studio-9999 on gentoo) but I was unable to record anything (failed to create video context or something similar)
Didnt dig any further but am curious how performance is if working correctly

VAAPI was buggy in the past with ffmpeg. Not sure what the state is today. If you see such kind of issues - open a bug about it.

Hi!

Digging up this thread because 3 years later, I have the same issue as @Vindieselwalker!

Did someone ever made OBS and HW encoding working on an AMD GPU???

Here's my config: I run Fedora 35 (running on X.org because of work) with OBS installed with Flatpak and I use the open source AMD drivers for an AMD RX6700 XT.

If I use the CPU (i.e. x264), it works fine. But if I use the "FFMPEG VAAPI" encoder, I get a blurry, 1 FPS video.

Here's my OBS config:

I haven't experimented recently. Did you try other codecs? Does it work with ffmpeg directly? I.e. may be it's a bug in OBS, not in ffmpeg/vaapi?

It has never worked for me. I was under the impression GPU encoding was not supported on Linux. I just tried now, and I got an error and it wouldn't even begin recording. It said to make sure my drivers were up to date.

GPU encoding should work through VAAPI in theory, if something doesn't, it's good to open a bug for it in Mesa.

Quoting: ShmerlDoes it work with ffmpeg directly?

I don't know how to do that using ffmpeg directly
Do you know the command line maybe? Otherwise I'll try and find that on the internets.

Some examples here:

* https://gist.github.com/Brainiarc7/95c9338a737aa36d9bb2931bed379219

Hmmm... weirdly enough, the ffmpeg package in Fedora (35) is not configured with `--enable-vaapi`.

I don't feel like building my own ffmpeg right now ^^'

Edit: the ffmpeg package comes from `rpmfusion-free`

Could be the same reason affects the library package that OBS is trying to use?
