SOLVED: Jellyfin Docker Container on intel GPU - openCL devices not found

[Timo Verbrugghe]

Allright the plot thickens. I have 2 N100 (Alder Lake) and 1 N5105 (Jasper Lake) device.

I ran

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -v verbose -init_hw_device vaapi=va:/dev/dri/renderD128 -init_hw_device opencl@va

inside a jellyfin container on each device to check if it detects opencl capabilities.

On a N5105 device with nixos as host OS, it works and opencl is detected.

So there seems to be an issue with N100 devices in Nixos with opencl...
