Description
I followed the official wiki page to configure. But, whenever I play any videos I get a persistent error saying, Device does not support the VK_KHR_video_decode_queue extension!. As far as I know, AV1 hardware encoding and decoding is supported on Intel Arc A750. I tried installing from both stable and unstable branches, but it didn’t help. Then, what is causing this problem and to whom should I report this issue?
Configuration
services.xserver.videoDrivers = [ "modesetting" ];
hardware.graphics = {
enable = true;
extraPackages = with pkgs; [
intel-media-driver
vpl-gpu-rt
intel-compute-runtime
];
};
environment.sessionVariables = {
LIBVA_DRIVER_NAME = "iHD";
};
hardware.enableRedistributableFirmware = true;
boot.kernelParams = [ "i915.enable_guc=3" ];
users.users.<service>.extraGroups = [ "video" "render" ];
