HDR to SDR Tonemapping with N100 CPU?

[InTrusta]

Is HDR to SDR Tonemapping possible with an N100 CPU? I can't get it to work and i find kind of conflicting sources for the general possibilities. 
I always get an "Playback failed due to a fatal player error" when i enable and try to watch a DV/HDR movie on a not HDR Device. Doesn't matter which
 Algorythm i use.

Ah i just found this thread https://forum.jellyfin.org/t-solved-tone...intel-n100 but i am on Ubuntu 24.04.01. Could this be related? @nyanmisaka was this updated in the docs?

Can you share your ffmpeg logs via privatebin.net? And how is Jellyfin installed in Ubuntu?

If you installed Jellyfin via apt (or our automated bash script) you will need to install Intel's compute runtime (intel-opencl-icd) via apt.

If you Jellyfin is running in Docker with the Linuxserver Jellyfin image you will need to add their OpenCL mod.

Sry for the late reply, i didnt't get any notification via email or in the inbox here. Had to acutally search my own thread to find it again ^^.
I can check the logs when im at home, will post here later.
I installed it through CasaOS, so it's just a docker container (i think). How would i add the OpenCL mod? Is that what @nyanmisaka is explaining in https://forum.jellyfin.org/t-solved-tone...intel-n100 ?

So i followed the instcutions from the github release here https://github.com/intel/compute-runtime/releases but it did not help, i still get the same error. But i am still not sure if i "added the OpenCL mod" with this.
I added the error logs.
I am on jellyfin/latest through the CasaOS docker image.
