This page is meant to help with techniques for getting accelerated video playback working in NixOS. This is generally done via libva and vaapi (and sometimes vdpau).

This is done by adding relevant libva-related packages to the hardware.opengl.extraPackages option.

Additionally, the vaapiIntel package can be overriden to enable Intel's Hybrid Driver.

Intel users also can enable intel-media-driver. It can be used at runtime with LIBVA_DRIVER_NAME=iHD mpv ... for example, if you use Mic92's mpv settings below.

Sample configuration:

 {
   ...
   nixpkgs.config.packageOverrides = pkgs: {
     vaapiIntel = pkgs.vaapiIntel.override { enableHybridCodec = true; };
   };
   hardware.opengl = {
     enable = true;
     extraPackages = with pkgs; [
       vaapiIntel
       vaapiVdpau
       libvdpau-va-gl
       intel-media-driver
     ];
   };
   ...
 }
 

Prepared Hardware configuration

Sometimes different opengl packages are required to achieve full performance. You can check different configuration repositories for similar hardware configuration:


Applications

Chromium

Needs a patch for VA-API support, see nixpkgs#21481 for current status.

MPV

@Mic92 needed the following configuration in ~/.mpv/config for mpv to use hardware acceleration for VP9 on Intel Broadwell:

hwdec=vaapi
vo=gpu
hwdec-codecs=all

This is based on the archlinux MPV article.

Other

See the Arch Linux wiki.
