==== VAAPI with Jellyfin in a NixOS Container ==== | |||
Containers don't inherit graphic drivers from their root system, so if you run Jellyfin in a NixOS container, you have to copy the <code>hardware.graphics</code> block from the main configuration into your container's configuration. | |||
You have to passthrough the graphics card device as well - usually it's located under <code>/dev/dri/card0</code> and/or <code>/dev/dri/renderD128</code>: | |||
<syntaxHighlight lang="nix"> | |||
{ | |||
allowedDevices = [ | |||
{ | |||
node = "/dev/dri/card0"; | |||
modifier = "rw"; | |||
} | |||
{ | |||
node = "/dev/dri/renderD128"; | |||
modifier = "rw"; | |||
} | |||
]; | |||
bindMounts = { | |||
"/dev/dri/card0" = { | |||
hostPath = "/dev/dri/card0"; | |||
isReadOnly = false; | |||
}; | |||
"/dev/dri/renderD128" = { | |||
hostPath = "/dev/dri/renderD128"; | |||
isReadOnly = false; | |||
}; | |||
}; | |||
config = | |||
# ... your container's configuration, including the hardware.graphics part! | |||
} | |||
</syntaxHighlight> | |||
You can check if you got the configuration correct by adding <code>libva-utils</code> to the container's <code>environment.systemPackages</code>, logging into the container (<code>machinectl shell container-name</code>), and running <code>vainfo</code> - if you got everything right, you should see something akin to: | |||
<syntaxHighlight> | |||
Trying display: drm | |||
libva info: VA-API version 1.22.0 | |||
libva info: Trying to open /run/opengl-driver/lib/dri/iHD_drv_video.so | |||
libva info: Found init function __vaDriverInit_1_22 | |||
libva info: va_openDriver() returns 0 | |||
vainfo: VA-API version: 1.22 (libva 2.22.0) | |||
vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 25.2.6 () | |||
vainfo: Supported profile and entrypoints | |||
VAProfileNone : VAEntrypointVideoProc | |||
VAProfileNone : VAEntrypointStats | |||
/* and many more, the list depends on your specific hardware */ | |||
</syntaxHighlight> | |||
With that, ffmpeg (and thus Jellyfin) should be able to use hardware transcoding. | |||
