VAAPI not properly detecting GPU capabilities

Hello,

I have a computer built with an i3-6100 and a AMD Radeon RX-550 GPU that i use to play movies.

I'm trying to configure it to use hardware decoding on the gpu, so i installed libva-mesa-driver and mesa-vdpau.

However, while my GPU should be capable of decoding up to 4k HEVC, vaapi seems to detect only MEPG2 capabilities, as shown in the output of vainfo :

Trying display: wayland
vainfo: VA-API version: 1.19 (libva 2.18.2)
vainfo: Driver version: Mesa Gallium driver 23.0.4 for AMD Radeon RX 550 / 550 Series (polaris12, LLVM 15.0.7, DRM 3.40, 5.10.187-1-MANJARO)
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            :	VAEntrypointVLD
      VAProfileMPEG2Main              :	VAEntrypointVLD
      VAProfileJPEGBaseline           :	VAEntrypointVLD
      VAProfileNone                   :	VAEntrypointVideoProc

This is quite a problem as my i3 CPU is not powerful enough to properly decode 4k HEVC in real time using software decode.
Would anyone have ideas about how to improve this ?
Thanks a lot.

Re: VAAPI not properly detecting GPU capabilities

I would expect more options, but your mesa and kernel are rather old.
There's also a problem with the kernel you're using :  5.10.187-1-MANJARO is not an archlinux kernel .

Are you running archlinux ?
If so, why are you using  a manjaro kernel instead of linux-lts510 from aur ?
