Accelerated Video Playback/zh: Difference between revisions

Latest revision as of 18:49, 15 August 2026

NixOS 中的视频播放加速通常是通过向 hardware.graphics.extraPackages 添加相关包来完成的。

安装

Intel

❄︎ /etc/nixos/configuration.nix

{
  pkgs,
  ...
}:

{
  hardware.graphics = {
    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
}

注意，intel-vaapi-driver 在较新的 Skylake (2015) 处理器上对于浏览器（基于 gecko/chromium）仍然表现更好。^[1]

对于 32 位支持，请使用 hardware.graphics.extraPackages32:

❄︎ /etc/nixos/configuration.nix

{
  pkgs,
  ...
}:
{
  hardware.graphics.extraPackages32 = with pkgs.pkgsi686Linux; [ intel-vaapi-driver ];
}

AMD

AMD 相关硬件（至少对于 Ryzen 5 iGPU 系列）支持开箱即用：

❄︎ /etc/nixos/configuration.nix

{
  hardware.graphics.enable = true;
}

NVIDIA

NVIDIA 官方并未支持 Linux 上的视频播放加速。虽然存在第三方实现，但不支持 Chrome^[2]，并且与其他实现^[3]相比存在显著限制。

拥有独立 iGPU 的 NVIDIA 用户通常应该更喜欢使用他们的 iGPU 来实现此目的，因此请参考上面的 Intel 和 AMD 部分。

仅具有 NVIDIA GPU 的用户可以尝试使用第三方实现；默认情况下，添加软件包到 hardware.graphics.extraPackages，但之后需要进行一些额外的设置才能使用^[4]：

❄︎ /etc/nixos/configuration.nix

{
  config,
  lib,
  ...
}:

{
  environment.variables.LIBVA_DRIVER_NAME = "nvidia";

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

  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";

      "gfx.x11-egl.force-enabled" = true;
      "widget.dmabuf.force-enabled" = true;

      # 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;
    };
}

测试您的配置

您可以通过运行以下命令来测试您的配置：nix-shell -p libva-utils --run vainfo

有关更多信息，请参阅 Arch Linux wiki 的硬件视频加速。

应用

Chromium

请参阅 Chromium 视频加速.

See Chromium#Accelerated_video_playback.

Firefox

请参阅 Arch Linux wiki 的 Firefox 部分.

MPV

您可以将以下配置放在 ~/.config/mpv/mpv.conf 中：

hwdec=auto

请参阅 Arch Linux wiki 的 mpv 部分.
