Thanks guys. That sounds really promising.
I assume this would then also work on 11th gen Intel chips? How about 12th? Or is that still an Intel/Linux issue?

I don’t know the status of NUC11 or NUC12.
I only have access to a NUC10 in our lab.
Engineering’s implementation, what I surmised based on the driver file names, looks good.
Just want to provide feedback by reporting the same as many others, 1.28.1.x seems to have broken HDR tonemapping for 10th gen also. Im using docker, an i3-10105 (UHD630), Kernel 5.19.3 (unraid 6.11-rc4)
Rolling back to 1.28.0.x “fixes” the issue for now.
Providing logs prior to the rollback:

Thank you and yes, quite well established about 1.28.1
We’re beyond that now and preparing for the new update which is extremely promising for everyone given the limited testing time I’ve had with it
Looks like this is still broken with 1.29.0.6209-9fa696df6 
Edit: Looks like HW transcoding is working again after I upgraded intel drivers and restarted the machine. Still too early to tell, but loos like the issues might finally be solved.

After update to 1.29.0.6209-9fa696df6 and using the latest intel driver(not 21.49.21786), the hardware HDR Tone Mapping finally back again. 
Update:
Some detail info about my plex server:
11th Gen Intel(R) Core™ i5-11500
Ubuntu 20.04 running in PVE lxc
The intel drivers were installed using the official intel repository. doc

It’d be useful if people said what NUC model or CPU they are using when they say things work or don’t work. That way people could get quick confirmation that some specific model or generation is working or not.

Confimed working on my system (Intel NUC11 - NUC11PAHi7):
Ubuntu 20.04.3 LTS
plexmediaserver/now 1.29.0.6219-b1b4d4871 amd64 [installed,local]
libigdgmm12/now 22.1.3 amd64 [installed,local]
intel-igc-core/now 1.0.11702.1 amd64 [installed,local]
intel-igc-opencl/now 1.0.11702.1 amd64 [installed,local]
intel-level-zero-gpu/now 1.3.24055 amd64 [installed,local]
intel-opencl-icd/now 22.35.24055 amd64 [installed,local]
To note, 4K to 1080 with subtitles still fails with the “server not fast enough” error. It says it HW transcodes but it still dies at the player. 1080p source transcode with subtitles is totally fine.
I see the same behavior on a NUC10I7FNH1 running Ubuntu 22.04.1, PMS 1.29.0.6219-b1b4d4871, and the latest Intel Compute Runtime (22.35.24055). It will hardware transcode 4K HDR successfully until subtitles are enabled.
I rolled back to PMS 1.28.0.5999-97678ded3 and ICR from 12/10/21 (21.49.21786), but at least it looks like progress is being made.
Ah, the dreaded subtitles again…
Thanks for the heads up. Waiting for 1.29.1 as Chuck suggested.
4k transcoding with subtitles is more or less the only issue I have with my plex now that the hardware transcoding is working. My shields can handle it but I have predominately rokus which can’t.
ALL:
I replicated the subtitles w/ Roku issue in previous versions of PMS and have given that to the Roku team to work on.
As for PMS-proper, I have the QA copy of PMS 1.29.1 in my possession and will be working through that on the subtitles issue to isolate down for the transcoder team as best I can.
Using latest Intel drivers (i5-11400) running on Ubuntu 22.04.1 LTS, linuxserver/plex 1.29.0.6209 sadly doesn’t seem to be working with my system, regarding the other posters, who got it to work. Did a restart and the whole dance. No HW-Transcoding with HDR-content, subtitles or not. Going back to 1.28.0.5999 and it’s running fine.
May I have a volunteer with either or both of:
- a RocketLake (-11xxx CPU)
- an AlderLake (-12xxx) CPU
to help me complete some testing ?
I have the NUC11PAHi7 - Intel Core i7-1165G7
Happy to help test
Same here: 11th Gen Intel(R) Core™ i7-1165G7 @ 2.80GHz
I have a Core™ i5-12600K, but run Plex server in a Docker container. Not sure if that rules me out.
Confirmed testing complete.
Native Install NUC11PAHi7 - Intel Core i7-1165G7 - Ubuntu 20.04.5

Testing complete on a 12th Gen Intel® Core™ i5-12600K @ 4500 MHz with Plex running in a Docker container. Hardware-accelerated video encoding and HDR tone mapping were enabled. Everything worked as expected including when PGS subtitles were active.
GPU stats bounced around quite a bit. Below is a screen capture of a spike.
Promising results. Well done, Plex team!
