So I am a bit bleeding edge here, I know. I’m on Ubuntu Server 22.04 which apparently does not support quicksync HDR → SDR tone mapping in Plex (yet). I’m running a newer Alder-Lake processor (i5-12400) and really don’t want to go to 20.04 due to a multitude of reasons (Alder-Lake isn’t even 100% yet in 22.04 with newer kernel features being backported to the LTS kernel).
Normal hardware transcoding is working great, but I can’t get HDR → SDR tone mapping to work. I believe I read somewhere that this was not yet supported.
Since this is a LTS release, I assume support will be coming soon?
Something that I’d like to point out is, at least by default, 22.04 doesn’t have the ‘beignet-opencl-icd’ package. Apparently ‘intel-opencl-icd’ is the replacement? I have installed ‘ocl-icd-libopencl1’ and ‘intel-opencl-icd’ and the software transcoder is being used for H.265 tone mapping.
The specifics are that all KabyLake and above CPUs must use Intel Compute Runtime 21.49.
For your machine, all CPUs CometLake or higher have always needed ICR.
I am working on the updated packaging which will be OS Distro, Release Version, and CPU sensitive . It will know what to have installed.
I have a developer’s package for 1.26.1.5772 available.
It’s the same 1.26.1.5772 except that it has my new packaging code with it.
It looks at the CPU, OS, and Version as part of the “Verification” process (preinstall).
It will report if you don’t have the proper versions installed. It does not report what you do have (yet / maybe not ever – not yet decided if I can do that well).
It gives you specific links to the binaries you need for Intel Compute Runtime (your AlderLake).
As you install them, do not be surprised if Ubuntu cautions about downgrading those modules. (Ubuntu 22.04 does include a higher version of GMMLIB than expected).
If you use this, please share the console output from the installation (so I can see what it printed) as well as /tmp/plexinstaller.log

Upgrading intel-opencl-icd to the newer version makes HDR → SDR not work again in hardware (as likely expected).
That being said, I didn’t revert back to the older version, as the processor is powerful enough to handle a single transcode in software (barely). Doing that and obtaining a correct image is better than using hardware and getting a garbled output.
It’s hard to explain, but for the garbled image, the video blocks appear all out of order and shifted, as well as some being green.
Happy to try anything else here. Actually seeing it say it was using hardware transcoding is certainly a step in the right direction for me.
I am confused on this reply. Doesn’t ICR include OpenCL?
By the way, I posted this in another thread, but this is how the video output looks when hardware tone mapping is being used. Software tone mapping produces a correct image (but takes all my CPU)
There are two. ocl-icd-libopencl1 and intel-opencl-icd
ocl-icd-libopencl1 is pre-Intel Compute Runtime and works with pre-CometLake CPUs in combination with beignet-opencl-icd
intel-opencl-icd is for use with Intel Compute Runtime.
It is required for all CometLake and above CPUs
As of Ubuntu 22.04, it is required for all Intel QSV-capable CPUs.
PMS expects Intel Compute Runtime version 21.49.21786, with all its support modules, to be installed for use with CometLake+ (Ubuntu 20.04) and all Intel QSV-capable CPUs (Ubuntu 21.04+)
Ubuntu 22.04 ships a newer version of Intel-gmmlib than 21.49.21786.
Care must be taken to apt-mark the package to prevent the file being overwritten again at the next update after downgrading it to 21.49.21786
This is easiest to verify by installing the 21.49.21786 files and verifying which are ‘downgraded’ .
I am working on getting the new package updates completed
If all continues to go as expected, the new installer will correctly detect the environment and versions then tell you which specific files to install or upgrade or downgrade if needed.
I went ahead and reverted my plex install to my previous hardware to keep my new rig open for testing and am keeping it in a state that should work with hardware tone mapping.
I went ahead and did a ‘apt-mark hold intel-opencl-icd’ and double checked my installed packages

Should I not be getting the garbled output as shown in my previous post? The ultimate question really is ‘Are there people with Alder Lake on Ubuntu 22.04 with these Intel packages installed where hardware HDR tone mapping is working correctly?’
Ok. I am OK with this (I realized I was bleeding edge when I bought it).
I’m just wanting to be sure that what I am observing aligns with what other people see vs a unique issue that my hardware is experiencing. Since this is literally a brand new rig and I have nothing to compare to, just want to make sure my current experience is ‘expected’ with the current state of things.
i am also having issues with HDR->SDR tonemapping and just hardware acceleration for transcoding in general on 22.04 with a coffee lake GPU. could thi be related?
