Unable to transcode on Jellyfin: renderD128 missing. Where can it be? (alien.top)

I have a media server based on Ubuntu server 22.03LTS with Kernel updated to the latest stable 6.5.7 running on Proxmox 8 as a VM. My machine is a Beelink EQ12 with an intel N100. Im using Jellyfin server 10.8.

My obstacle is that I cannot activate the transcoding on Jellyfin because I cannot see the renderD128 in /dev/dri. I thought It was because my processor is quite new so I needed the latest kernel but.. after installing the latest kernel and rebooting... I still don't see the renderD128.

It's frustrating. I don't know what else to do.

So, open a terminal and check if the device is there on your system?

Follow the excellent Jellyfin documentation for hardware-transcoding.

The /dev/dri doesnt magically appear when you run Jellyfin inside a VM. You should also ask /r/Proxmox if you need help to passthrough your device to the VM.

The others gave you a solution but note the following:

Jellyfin in a VM means that once you passthrough the GPU to the VM, you will lose graphical capabilities on the host. That could be a dealbreaker. Segmenting the GPU is inefficient.

I host my Jellyfin in a LXC because I can passthrough the GPU without reserving it to the LXC.
