Unable to setup HW acceleration on Celeron N4500 (Intel UHD 600)

[Nikojiro]

Hi,

I'm trying to set up hardware acceleration on a Chuwi Herobox pro 2021 (Celeron N4500, 8GB of RAM, Intel UHD 600). I'm running Ubuntu server and installed the native Jellyfin package (using the official install script), version 10.10.7. I followed the steps from the tutorial for Intel GPUs).

Here's the output of a few commands:


:~$ ls -l /dev/dri

I've tried using both VAAPI and Intel QSync to no avail. Playback fails with either error 234 or 218 respectively.
Here's the log for a VAAPI playback attempt:

I have no idea what's wrong here, thanks for helping.

Oh well, it seems I had not understood how transcoding works, and that my issue is on the client side. I've set up Jellyfin Media Player on my PCs and the Jellyfin app + MPV on my Android phone, everything is working now, including HEVC 10bit vids.Before that I was using the web player, beginner mistake...
