VA-API Hardware Acceleration Not Working

I followed the steps in https://wiki.archlinux.org/title/Hardwa … celeration
Installed the needed packages, used the direct backend and set the enviroment variables but despite that I keep getting the following output when I use vainfo

Trying display: wayland
vaInitialize failed with error code -1 (unknown libva error),exit

Re: VA-API Hardware Acceleration Not Working

You said you did things you didn't say which things you did and how. What did you setup exactly, what hardware do you have exactly and where and how did you set "environment variables"? What's the output of 

printenv

I have an NVIDIA RTX 3050 and a Ryzen 5, I added the enviroment variables to .zshrc

Re: VA-API Hardware Acceleration Not Working

LIBVA_DRIVER_NAME=vdpau

With recent cards NVDEC usually works better, try LIBVA_DRIVER_NAME=nvidia .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Did that, now it says this

Re: VA-API Hardware Acceleration Not Working

Sanity checks:

pacman -Qs libva

2. Why are you looking for VAAPI? You basically want to use VDPAU whenever you can, not a https://wiki.archlinux.org/title/Hardwa … ion_layers

As far as I know, vdpau doesn't work on firefox. Correct me if I'm wrong

Re: VA-API Hardware Acceleration Not Working

libva-vdpau-driver isn't even intalled, explaining the original error

Next sanity check, are you even running on the nvidia GPU?

glxinfo -B

Edit: video acceleration in browsers is a contant PITA anyways, but will require vaapi, yes.

Done.
It gave a core dump error but I removed the LIBVA_DRIVER_NAME variable and now it works....running on the AMD iGPU
There goes my sanity

Edit: it doesn't work with the nvidia card when I specify it on Wayland (displays the error below), on X11 it works

libva error: /usr/lib/dri/nvidia_drv_video.so init failed

Re: VA-API Hardware Acceleration Not Working

https://wiki.archlinux.org/title/PRIME# … figuration
You can also just use prime-run from the nvidia-prime package but it's very unlikely that you actually want to do that at all.

Why are you trying to run video decoding on the nvidia GPU when the display server runs on the APU?
Unless nvidia supports some codec your APU does not, there's probably only downsides with that.
