Quicksync doesn't work after enabling HDR Tone Mapping

Plex Media Server

Server Version#:1.25.3.5409
Player Version#:

Hello,
for Plex i bought a nuc 10210u and installed Ubuntu 21.10. HW-Transcoding runs well until Enabling HDR-Tone Mapping. If enabled, the CPU get high CPU-Workload and I can’t even transcode one 4K movie. I also installed:

" sudo apt install ocl-icd-libopencl1 beignet-opencl-icd"

I’m looking for a solution since hours, but I can’t find.
Had anyone the same problem and could fix it?

You would have to use Ubuntu 20.03 for all the drivers to work together. If I may suggest, only use LTS versions of Ubuntu since that will give the least amount of headaches and that is what Plex works with when testing.

Tieberius is correct. 20.04.3 LTS works. 21.x has been very problematic for folks.

Further, make certain to install the Intel Compute Runtime modules as directed by the installer.

Should you have difficulty , the file /tmp/plexinstaller.log will report what it found (your harware & software inventory). Please share this file

Ok Now i installed Ubuntu 20.04.3. I installed the packages from my post and additional Intel Compute Runtime modules. After that I restarted pms. But CPU-Workload still gets high when Enabling HDR Tone Mapping…
I can’t find the file plexinstaller.log in the tmp Folder. Neither in var/tmp or /tmp.

The file /tmp/plexinstaller.log will remain there until (on most system) until next restart of the host.

If you stop, uninstall , then reinstall the code again, you’ll get it to recreate the inventory report. It won’t impact Plex in any way

Ah thanks.
Here it is:

Try downgrading the intel runtime drivers to 21.49.21786, per the linked post. I had the same issue last month, and it worked for me.

Thank you for the inventory file.

You forgot to install Intel Compute Runtime as directed by the installer. (NeedIntelCompute=1)
