OpenCL is used for tonemapping.
Transcoding is done in the QSV ASIC.
“LG Colors” is HDR so that confirms what I see.
If you go to 1.32.5.7210 , did that work? (last release before staffing changes)
I understand, and I don’t think I said anything which suggests otherwise 
. Tone mapping failing (and causing an HW transcoding fallback to occur) is what we’re talking about here, I think?
I don’t have access to 1.32.5.7210, so I can’t confirm. I tested on 1.32.6.7468 and 1.32.5.7349 (which resolves the current issue, at least for some users). At any rate, no transcoder changes were highlighted between 7210 and 7349 in the release notes… I hope that means no changes were made to transcoder changes between those releases 
.
Edit:
I realized that some of that seemed snarky reading it back. It’s not intended. I’m just trying to relate information as concisely as possible. I sometimes leave out the niceties, but I do appreciate your looking into this @ChuckPa.
Here: 1.32.5.7210.deb
This works on Ubuntu / Debian platforms and can be installed in docker containers using dpkg
Thanks for the link. I can confirm that, in my environment at least, 1.32.5.7210 works as well. HW accelerated transcoding with HDR tone mapping functioned as expected (intel_gpu_top shows hardware resources being used and playback is smooth and vibrant, color-wise). As is the case with 1.32.5.7349. There are no obvious differences in behavior between these releases on my system.
(N5105, Pop!_OS 22.04 LTS, Linux kernel 6.4.6)
Being pedantic and rephrasing , if I may?
- 1.32.5.7210 - Fully functional, with HDR tone mapping enabled, AS EXPECTED
- 1.32.6.xxxx - HDR tonemapping faulty
I ask in these terms because release 1.32.5.7210 is a clear demarcation in our software system. I can grab it and know everything will work.
The demarcation as I have experienced it is 1.32.5.7349; both releases after it ( (not counting .7431 as an Nvidia Shield-specific release) have been problematic.
Regarding 1.32.6.7468, I can’t go back and test it to be 100% certain if it was affected. If you can provide a download link I’ll test it to be sure.
I’m gonna be honest, I assumed that for tonemapping I would need the option to be selected, so I haven’t tested it without it.
Now that you mentioned it, I went back and unticked the option and HW tonemapped transcoding is working for 4k HDR videos (with embedded subs on).
So the capability is there, something must be broken on the backend and creating some kind of conflict somewhere.
Thanks for the tip anyway. Will continue to follow this closely.
I’m sorry @ChuckPa but unfortunally this seems to be harder for you…
I discovered this bug first time on 1.32.5.7349 and all newer version (I wasn’t using Plex for a while), than I decided to search help on the forum, I discovered threads similar to this and I understood that I had to downgrade the version I had installed.
Now I’m on plexmediaserver_1.32.1.6999-91e1e2e2c_amd64.deb and still have to disable “HDR tone mapping” to have HW accelerated transcoding (but I gain the HDR tone mapping for free!!!)…
So, even if you say that version 1.32.5.7210 “is a clear demarcation in our software system” it is not demarcating enough…
I also tried to delete the folder content of the folder “/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Codecs/” except the file .device-id as sudgested on some other thread I read, same result.
When I use Plex 1.32.1.6999-91e1e2e2c, inside that folder I have:
root@server:~# ls -hla "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Codecs"/
totale 24K
drwxr-xr-x 5 plex plex 4,0K 9 set 18.39 .

drwxr-xr-x 3 root root 4,0K 6 set 20.44 EasyAudioEncoder-1847-linux-x86_64
When I update Plex to 1.32.6.7468-07e0d4a7e I have:
root@server:~# ls -hla "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Codecs"/
totale 24K

drwxr-xr-x 3 root root 4,0K 6 set 20.44 EasyAudioEncoder-1847-linux-x86_64
but always same issue:
- HDR tone mapping ON = software transcoding
- HDR tone mapping OFF = HW transcoding with free HDR tone mapping too
I hope this time you can have a more clear idea of what we are encountering…
The demarcation points here are:
1.31.3.6868 - Before the transcoder and IMD update
1.32.0.6973 - First release with the updates in place
1.32.1.6999 - Bug fixes of the regression fixes but not all.
1.32.5.7210 - Several bug fixes, but not all, ADDED AMD support + GPU selection
1.32.5.7349 - Last release before staff changes.
1.32.6.xxxx - Work since staff changes.
As you can see, there was a lot ‘in flight’.
In all this, there is a “recipe” to be found. that’s what I’m trying to discover.
- Which transcoder core
- Which IMD
- Which PMS - Transcoder interface code
I can provide other DEB/SPK files to figure this out PROVIDED folks don’t get caught up in minutia.
I think the best goal here is to “get the biggest bang for the buck” and working from there.
Agree?
Given you discovered the bug here…
Do you support my statement that 1.32.5.7210 works for you?
No, I don’t support your statement, just tried:
always same issue:
- HDR tone mapping ON = software transcoding
- HDR tone mapping OFF = HW transcoding with free HDR tone mapping too
Let me try all other demarcation point version and I will let you know
I just noticed this regression myself on an i7-13700 running 1.32.6.7468. Plex installed within a privileged lxc container running ubuntu with a proxmox host. I’m happy to provide any logs that could be helpful I’m just not sure exactly what you need? Everything functioned perfectly at one point but as of now I’m experiencing the behavior described in this thread.
Logs from within the plex lxc ubuntu jammy container:

Thanks. This is what I need to know.
Also, Please include the testing parameters && DEVICES.
e.g: (I need to figure out a template but here’s a first shot)
PMS - 1.3x.yyyy
GPU - xxxxx
Player - BLAH
HDR tone mapping = OFF
HW Transcoding = PASS
----
HDR tone mapping = ON
HW Transcoding = FAIL
Please include DEBUG logs after testing. It’ll capture everything I need to see
This is what I have:

Great, here is everything you requested including debug log. First playback attempt is with tone mapping enabled with failure, 2nd is with tone mapping disabled with success. Please let me know if there’s anything else I can provide that’s helpful!

Do you happen to have the same PMS version I’ve used ?
(you can either grab the image and apply or use dpkg from inside the container command line)
We know there are major inconsistencies with 1.32.6
I can’t try every version but just for test I jumped back to 1.28.1.6104 and it WORKS!!!
- HDR tone mapping ON = HW transcoding works!!!
- HDR tone mapping OFF = HW transcoding works!!!
The strange thing is that while installing this version the installation logs printed 3 warning that the newer version installers doesn’t print:

That completely agrees with what I am seeing in development logs.
Anything up to, and including, 1.29.2.6364 should be 100% working for everything – EXCEPT the bug fixes in PMS itself for the different features
I can give you any version you wish… All you need do is ask
What about this warning? We can ignore that?
