SOLVED: OpenCL tonemapping stopped working

[caius]

I have a jellyfin server which used to do opencl tonemapping OK. I've noticed now that it gives an error when trying to transcode a file which requires tone mapping and playback does not start.

The server is a Celeron J4105 with UHD 600 graphics. Quicksync hardware acceleration works OK, as does VPP tone mapping. It's running on Ubuntu 24.04 LTS directly (ie not in docker).

Jellyfin version is 10.9.11.

It looks like some problem with the opencl driver but I'm not sure how to troubleshoot it. If I run clinfo that also crashes with the same error message. I'm not sure if this is a configuration error somewhere or if there's an issue with the driver itself. I'd be grateful if anyone has any ideas.

vainfo requires additional parameters

Code:

sudo /usr/lib/jellyfin-ffmpeg/vainfo --display drm --device /dev/dri/renderD128

But to the actual problem, try just reinstalling the opencl package.

Code:

sudo apt purge intel-opencl-icd
sudo apt install intel-opencl-icd

I tried removing the package and running clinfo gives the expected response without crashing:

Code:

Number of platforms                              0

ICD loader properties
  ICD loader Name                                OpenCL ICD Loader
  ICD loader Vendor                              OCL Icd free software
  ICD loader Version                              2.3.2
  ICD loader Profile                              OpenCL 3.0

After reinstalling it, the crash returns.

What is the output of this command?

Code:

sudo apt list --installed | egrep -i "igc|intel|opencl"

It seems to have been a problem either with the specific package ubuntu was installing or some dependency. I went to the Intel compute runtime github and installed the latest packages from there after purging the ubuntu version.

Transcoding with ffmpeg now works correctly and clinfo no longer crashes.
Ubuntu was installing version 23.43.27642.40-1ubuntu3 and the latest intel release is 24.35.30872.22.

What is the output of this command?

This was run after I'd installed the intel packages, so not really needed but I'll put it for reference anyway:
