va-api not running on wayland, but working on x11

checked with vainfo the settings of my configuration and that's the output:

Trying display: wayland
error: XDG_RUNTIME_DIR is invalid or not set in the environment.
Trying display: x11
vainfo: VA-API version: 1.18 (libva 2.18.1)
vainfo: Driver version: Splitted-Desktop Systems VDPAU backend for VA-API - 0.7.4
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            :	VAEntrypointVLD
      VAProfileMPEG2Main              :	VAEntrypointVLD
      VAProfileMPEG4Simple            :	VAEntrypointVLD
      VAProfileMPEG4AdvancedSimple    :	VAEntrypointVLD
      <unknown profile>               :	VAEntrypointVLD
      VAProfileH264Main               :	VAEntrypointVLD
      VAProfileH264High               :	VAEntrypointVLD
      VAProfileVC1Simple              :	VAEntrypointVLD
      VAProfileVC1Main                :	VAEntrypointVLD
      VAProfileVC1Advanced            :	VAEntrypointVLD

so i believe that for some reason XDG_RUNTIME_DIR is not vaild even if it's value is: "/run/user/1000", that is a valid value according to the Arch wiki.
did i miss to configure some wayland's env variables?

software: propriery nvidia drivers (nvidia package), gnome 44.1 on wayland, arch
hardware: nvidia 1050ti, pascal architecture

maybe the problem is the fact that i run vainfo with sudo privileges.

installing this solved the problem: https://github.com/elFarto/nvidia-vaapi-driver/
