[SOLVED] Vaapi and/or vdpau not working on GT950 with nouveau

Recently I noticed that vaapi and/or vdpau acceleration is not working on my box anymore, the hardware is an NVidia GT950 card with nouveau.

Nouveau works just fine, no problems, lags, or tears.

I have xf86-video-nouveau installed for the graphics driver, otherwise installed related packages are:

mesa
mesa-utils
libva
libva-utils
libvdpau
vdpauinfo

in the envirronment file (/etc/bash.bashrc in my case) I have set

export VDPAU_DRIVER="nouveau"
export LIBVA_DRIVER_NAME="nouveau"

all of the are sourced correctly, but acceleration just does not work.

vainfo shows:

Trying display: wayland
Trying display: x11
libva error: /usr/lib/dri/nouveau_drv_video.so init failed
vaInitialize failed with error code 2 (resource allocation failed),exit

(/usr/lib/dri/nouveau_drv_video.so exists, it is a symlink pointing to libgallium)

vdpauinfo shows:

display: :0.0   screen: 0
Error creating VDPAU device: 23

I'm pretty sure all of this was working until somewhere around the time libva-mesa-driver and mesa-vdpau was merged with mesa.

Can you help me out with this?

Sanity check, this is a Maxwell chip? Not using the binary driver is deliberate?
You do have https://aur.archlinux.org/packages/nouveau-fw ?

Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General and … oh,

xf86-video-nouveau installed

try w/o that first.

Removing xf86-video-nouveau just stupidly solved it. Old install, and I do not read enough news I guess.

Thank you for the help!
