I switched off hardware acceleration/transcoding entirely and it works. With it enabled dashboard looks like this: https://imgur.com/a/DkkMQ9H

Sorry about the language, I've set it to English, but it's not changing.
So I'm prettu sure that some transcoding options/formats are wrong.

I've looked at these menus enough that I know what they are just by the positioning.

The Jellyfin transcode settings are not optimal, but they are not going to cause any problems as is.  The problem is that Jellyfin doesn't have access to the iGPU.

Code:

[AVHWDeviceContext @ 0x55956fc26a40] No VA display found for any default device.
Device creation failed: -22.
Failed to set value 'vaapi=va:,kernel_driver=i915,driver=iHD' for option 'init_hw_device': Invalid argument
Error parsing global options: Invalid argument

Did you pass the GPU into the container?  Ignore the arrow in the top right.  This screenshot was originally for another user.  I'm not at home to take a new one.
