NixOS 中的加速视频播放通常是通过向 hardware.opengl.extraPackages 添加相关包来完成的。
安装
Intel
❄︎ /etc/nixos/configuration.nix
{
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
{
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.opengl.enable = true;
}
测试您的配置
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
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.
Also see
- Arch Linux wiki#Hardware video acceleration.
- nixos-hardware has example configurations for various types of hardware.
