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).
Accelerated video playback in NixOS is generally done by adding relevant packages to {{nixos:option|hardware.opengl.extraPackages}}.


This is done by adding relevant <code>libva</code>-related packages to the <code>hardware.opengl.extraPackages</code> option.
== Installation ==
 
=== Intel ===
Additionally, the <code>intel-vaapi-driver</code> (previously <code>vaapiIntel</code>) package can be overridden to enable [https://github.com/01org/intel-hybrid-driver Intel's Hybrid Driver].
{{file|/etc/nixos/configuration.nix|nix|<nowiki>
 
Intel users also can enable <code>intel-media-driver</code>. It can be used at runtime with <code>LIBVA_DRIVER_NAME=iHD mpv ...</code> for example, if you use Mic92's mpv settings below.
 
Sample configuration:
<syntaxHighlight lang=nix>
{
{
   ...
   hardware.graphics = { # hardware.opengl in 24.05 and older
  nixpkgs.config.packageOverrides = pkgs: {
    intel-vaapi-driver = pkgs.intel-vaapi-driver.override { enableHybridCodec = true; };
  };
  hardware.opengl = {
     enable = true;
     enable = true;
     extraPackages = with pkgs; [
     extraPackages = with pkgs; [
       intel-media-driver # LIBVA_DRIVER_NAME=iHD
       intel-media-driver # For Broadwell (2014) or newer processors. LIBVA_DRIVER_NAME=iHD
       intel-vaapi-driver # LIBVA_DRIVER_NAME=i965 (older but works better for Firefox/Chromium)
       intel-vaapi-driver # For older processors. LIBVA_DRIVER_NAME=i965
      libvdpau-va-gl
     ];
     ];
   };
   };
   environment.sessionVariables = { LIBVA_DRIVER_NAME = "iHD"; }; # Force intel-media-driver
   environment.sessionVariables = { LIBVA_DRIVER_NAME = "iHD"; }; # Optionally, set the environment variable
  ...
}
}
</syntaxHighlight>
</nowiki>}}
Note, <code>intel-vaapi-driver</code> still performs better for browsers (gecko/chromium based) on newer Skylake (2015) processors.<ref>https://github.com/intel/media-driver/issues/1024</ref>
 
For 32-bit support, use {{nixos:option|hardware.graphics.extraPackages32}}:
{{file|/etc/nixos/configuration.nix|nix|<nowiki>
{
  # hardware.opengl.extraPackages32 in 24.05
  hardware.graphics.extraPackages32 = with pkgs.pkgsi686Linux; [ intel-vaapi-driver ];
}
</nowiki>}}

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

Accelerated video playback in NixOS is generally done by adding relevant packages to hardware.opengl.extraPackages.

Installation

Intel

/etc/nixos/configuration.nix

{
  hardware.graphics = { # hardware.opengl in 24.05 and older 
    enable = true;
    extraPackages = with pkgs; [
      intel-media-driver # For Broadwell (2014) or newer processors. LIBVA_DRIVER_NAME=iHD
      intel-vaapi-driver # For older processors. LIBVA_DRIVER_NAME=i965
    ];
  };
  environment.sessionVariables = { LIBVA_DRIVER_NAME = "iHD"; }; # Optionally, set the environment variable
}

Note, intel-vaapi-driver still performs better for browsers (gecko/chromium based) on newer Skylake (2015) processors.[1]

For 32-bit support, use hardware.graphics.extraPackages32: 

/etc/nixos/configuration.nix

{
  # hardware.opengl.extraPackages32 in 24.05
  hardware.graphics.extraPackages32 = with pkgs.pkgsi686Linux; [ intel-vaapi-driver ];
}

AMD

AMD configuration (at least for Ryzen 5 iGPUs) works out of the box: 

/etc/nixos/configuration.nix

{
  hardware.opengl.enable = true;
}

Testing your configuration

You can test your configuration by running: nix-shell -p libva-utils --run vainfo

See Arch Linux wiki#Hardware video acceleration for more information.

Applications

Chromium

See Chromium#Accelerated_video_playback.

Firefox

See Arch Linux wiki#Firefox.

MPV

You can place the following configuration in ~/.config/mpv/mpv.conf: 

hwdec=auto-safe
vo=gpu
profile=gpu-hq
gpu-context=wayland ; On wayland only

See Arch Linux wiki#mpv.
