Configuring VDPAU on hybrid nvidia-intel GPU system

Hi manjaro peeps,
I wanted to configure VDPAU to use it with shadow-tech. I followed what it said on the wiki page linked above. But it didn’t work and still showing error:

$ vainfo
vaInitialize failed with error code -1 (unknown libva error),exit

Can someone point me in the right direction to get it working?
Thanks a bunch!

By ‘configuring’ … what did you do exactly ?

For the intel, depending on what it exactly is, supports VAAPI through package intel-media-driver or libva-intel-driver, and if new enough might also need linux-firmware

Nvidia, on the other hand only supports VDPAU through package nvidia-utils

libva-vdpau-driver will ‘translate’ a VAAPI layer using a VDPAU backend (this enables VAAPI on your nvidia)

libvdpau-va-gl will ‘translate’ a VDPAU layer using a VAAPI backend (this enables VDPAU on your intel)

…thing is … I am relatively sure you should have all of those packages by default already.

So whether you are doing vainfo (which should use the intel, and thus supports VAAPI without any translation) or prime-run vainfo (which should use the nvidia, and if the above package is installed, allow it to use VAAPI through a VDPAU backend) it shouldnt fail.

So … do you have all those packages ?
How have you managed your drivers ?
What did you do to ‘configure hardware acceleration’ ?

Also … might be useful to include your inxi -Fazy and/or mhwd -li


Thanks. I had some packages missing. I had the wrong one installed among following:

Ah. yeah … the media one is newish.
(I hope this doesnt mean we have a bad profile in mhwd or default install though…)

Here are the inxi -Fazy and mhwd -li you asked for. I hope they will help. It didn’t work with the mhwd installation.

Hm. OK. yes … it seems your 510 is in the ‘newer’ category … so that package should have been included…
