m Add an example for AMD iGPU. I'm adding it because I searched examples in the wiki and elsewhere and didn't find anything related to AMD. It was maybe too obvious but just one line of config is enough.

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).
<languages/>
<translate>
<!--T:1-->
Accelerated video playback in NixOS is generally done by adding relevant packages to {{nixos:option|hardware.graphics.extraPackages}}.
</translate>


This is done by adding relevant <code>libva</code>-related packages to the <code>hardware.opengl.extraPackages</code> option.
<translate>
 
== Installation == <!--T:18-->
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].
</translate>
 
<translate>
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.
=== Intel === <!--T:19-->
 
</translate>
Sample Intel configuration:
{{file|/etc/nixos/configuration.nix|nix|<nowiki>
<syntaxHighlight lang=nix>
{
{
  ...
   hardware.graphics = {
  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>}}
<translate>
<!--T:2-->
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>
</translate>


32 bit example:
<translate>
<syntaxhighlight lang="nix">
<!--T:3-->
hardware.opengl.extraPackages32 = with pkgs.pkgsi686Linux; [ intel-vaapi-driver ];
For 32-bit support, use
</syntaxhighlight>
</translate> {{nixos:option|hardware.graphics.extraPackages32}}:
{{file|/etc/nixos/configuration.nix|nix|<nowiki>
{
  hardware.graphics.extraPackages32 = with pkgs.pkgsi686Linux; [ intel-vaapi-driver ];
}
</nowiki>}}
<translate>
=== AMD === <!--T:4-->


AMD configuration (at least for Ryzen 5 iGPUs) works out of the box:<syntaxhighlight lang="nix">

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

=== NVIDIA ===


== Prepared Hardware configuration ==
NVIDIA do not officially support accelerated video playback on Linux. A third-party implementation exists, but does not support Chrome<ref>https://github.com/elFarto/nvidia-vaapi-driver#chrome</ref>, and has significant limitations compared to the other implementations<ref>https://github.com/elFarto/nvidia-vaapi-driver#codec-support</ref>.
Sometimes different opengl packages are required to achieve full performance. You can check different configuration repositories for similar hardware configuration:
* [https://github.com/NixOS/nixos-hardware The NixOS-Hardware Repository]


== Testing your configuration ==
NVIDIA users with a separate iGPU should generally prefer to use their iGPU for this, and therefore look to the above Intel and AMD sections instead.


You can test your configuration by running: <code>nix-shell -p libva-utils --run vainfo</code>
Users with only an NVIDIA GPU can attempt to use the third party implementation; the package is added to <code>hardware.graphics.extraPackages</code> by default, but it requires some additional setup to be useful<ref>https://github.com/elFarto/nvidia-vaapi-driver#configuration</ref>:

{{file|/etc/nixos/configuration.nix|nix|<nowiki>
{ config, lib, ...}: {
  environment.variables.LIBVA_DRIVER_NAME = "nvidia"


== Applications ==
  # If used with Firefox
  environment.variables.MOZ_DISABLE_RDD_SANDBOX = "1";


===Chromium===
  programs.firefox.preferences = let
    ffVersion = config.programs.firefox.package.version;
  in {
    "media.ffmpeg.vaapi.enabled" = lib.versionOlder ffVersion "137.0.0";
    "media.hardware-video-decoding.force-enabled" = lib.versionAtLeast ffVersion "137.0.0";
    "media.rdd-ffmpeg.enabled" = lib.versionOlder ffVersion "97.0.0";


See [[Chromium#Enable GPU accelerated video decoding (VA-API) | Chromium]].
    "gfx.x11-egl.force-enabled" = true;
    "widget.dmabuf.force-enabled" = true;


=== Firefox ===
    # Set this to true if your GPU supports AV1.
    #
    # This can be determined by reading the output of the
    # `vainfo` command, after the driver is enabled with
    # the environment variable.
    "media.av1.enabled" = false;

You can place the following configuration in <code>~/.config/mpv/mpv.conf</code>
You can test your configuration by running: <code>nix-shell -p libva-utils --run vainfo</code>
for mpv to use hardware acceleration for VP9 on Intel Broadwell (and probably later):
