I did not alter the LSIO container after updating. Can’t remember what I did months ago when it originally broke.

Tonemapping works on GeminiLake.
The Plex container is a Ubuntu environment
Below is it working on native Ubuntu installation
The results are the same (Unraid 6.12.4 with kernel 6.1.49). See the logs

Hardware transcode still doesn’t work for me
Synology DS918+ w. Celeron J3455 and DSM7
PlexMediaServer-1.32.6.7557-1cf77d501-x86_64_DSM7.spk
If I un-check hardware transcode then it will work, but not with it enabled.
Revert back to 1.32.1.6999 and it works with hardware transcode on (as it always did up until 1.32.2)
When it fails I see this in logging.

I need much more than 6 lines to diagnose with.
I have it working on ApolloLake in the lab as shown here.

There are issues with certain Android devices we’re working on.
For purposes of verification, please use Plex/Web player only
On my DS920+ live-tv streaming works fine:
But only when playing in Chrome, Synology is using hw transcoding
Anyway, i don’t have 4k content.

Chrome Version 117.0.5938.132 (Official Build) (64-bit)
Plex for windows: Version 1.79.1.3984-879339ed
I re-updated to 1.32.6.7557 and retried using the player as you suggested. It took a few seconds but it did start to play transcoded content for a 720 (0.7mb/s) file.
I retried with Chrome and it took a minute but it also began to play.
Then I tried a 4K file in the player and it failed with an error.
An unknown error occurred (4294967279)
Error code: 4294967279
File transcode in the player was HEVC BT709 2160@35mb/s > 1080@8mb/s
Didn’t test in Chrome
Retested with 1.32.1.6999 and 1080@8mb/s played
What logs would you need - Debug or Verbose?
nvm - I also enabled Use hardware-accelerated video encoding and it transcoded ok.
Didn’t need it on the older version, but it does now.
Problem was on my side. Looks like this sorted it, thanks
Getting the same error as many here on any recent version of Plex with 4K HDR content to be tonemapped + transcoded. Normally I don’t mind downgrading and waiting to resolve issues like these, but quite literally every single recent version of Plex has the same exact issue (1.32.5,1.32.4,1.32.3,1.32.1, 1.31.3, etc.) Luckily the 13600k’s 8 virtual cores actually somehow manage to keep up with the software transcoding fallback, but it can really only handle about 1 HDR transcode at a time (plus using 95% CPU is less than ideal). Also note that this is running in a Docker container in a VM, but the Docker container clearly has GPU support because it can transcode any file that isn’t HDR w/integrated graphics.
This is on a 13600k with Intel UHD 770 graphics (quicksync). The source file is 4K HDR10 (HEVC Main 10). This does not happen with 4K files that are not HDR but need transcoding. I appreciate @ChuckPa and his constant feedback, but it is shocking that the Plex engineers haven’t nipped this in the butt for months, if not longer.
EDIT: i965 workaround does not work for my CPU because AFAIK i965 only supports older Intel HD revisions. Will there be a new plex beta soon?
- What is the host distro & version?
- Need log files ZIP – not a screenshot excerpt (which isn’t actionable)
Respectfully, I recommend “ALL STOP” on how you have Plex configured.
– Unless you’re using ESXi, the VM is probably overkill
– Docker in a VM is “just because I can” and overcomplicating — Wrong.
When you put PMS in Docker , inside a VM, you have 3 layers to deal with.
Get any one of them wrong and it’s GAME OVER.

While I definitely understand, I’m pretty sure that my issue is not my setup (which in my case is required) because transcoding does function when tonemapping is not involved. I’ve attached logs of the transcoder failing with a 4K HDR file and succeeding with a regular 1080p transcode.
Additionally, while I’m glad the 13400 is functioning properly, it does not have the same GPU (730 != 770). While their architecture is identical, I do wonder if that is playing a part here. Nevertheless I can test out plex on my hypervisor system soon with a kernel module loaded in but I would be shocked if I got a different result.

How are you passing the GPU? What’s the spec you’re using?
Supplemental:
The 6.5 kernel is problematic (being kind).
Using a ‘boxes’ QEMU hypervisor ?
Got it, here are some answers:
I’m passing the GPU through with a kernel module on both the guest/hypervisor that enables SR-IOV support:
This lets multiple VMs use the same GPU.
I then installed vainfo and intel-media-driver on both the host/guest using apt. Docker is then passed /dev/dri.
Also, I’m just using the proxmox “Create VM” function, which I believe is a QEMU hypervisor. Would you like me to try and downgrade the kernel to 6.2? I can always try plex on the hypervisor as well
EDIT: Downgrading the kernel now
So turns out I can’t really downgrade the kernel because 6.1 is missing multiple critical symbols for SR-IOV. But that’s all the information I know of currently. vGPU (SR-IOV) with Intel 12th Gen iGPU [Updated 2023]
here is the guide I followed for more information. @ChuckPa any thoughts?
NO NO NO. don’t do that. You’re ASKING for trouble.
The Intel Media Driver isn’t up to that. It hasn’t worked all year for anyone.
This is where you need to simplify.
- Dump the VM
- Dump the SR-IOV
- Run native on the host -OR- , at most, in a container which uses the native kernel drivers.
If you’re gaming, then maybe… but not with Plex and simultaneous QSV + OpenCL.
The best use case for SR-IOV is when you have GPUs in a different box than the computational host. When the CPU and the GPU are both singular on the same host – it is unnecessary because the kernel provides all the necessary isolation and context switching.
Please tell me what you have which REQUIRES SR-IOV ?
