So likely Synology DS920+ on DSM 7.2
CPU: GeminiLake
Kernel: 4.4.302+
is not going to be supported 
?
Synology is/will be supported.
Synology 4.4 kernel is/will be supported.
We’re trying to get the Intel drivers GeminiLake bug resolved because it impacts far more than just Synology users. (Popular CPU)

See the PMS release notes. You should have hardware accelerated transcoding and tone mapping with PMS 1.40.4.8679 (current public release) or later.
I’ve a DS918+ (J3455/Apollo Lake) which was also impacted. Hardware accelerated transcoding and tone mapping both work with PMS 1.40.4.8679.
Oh wow, just tested it and 4k HDR HEVC to 1080p transcoding is actually playable this is actually so helpful, and couldn’t have been at a better time since I have family traveling out of country this week and they will have limited internet access. Thank you for all the hard work, and can’t wait for more details on this.
Hey Chuck,
24.04.1 is coming out on August 15th. Are all the issues fixed (i.e. OpenCL, Intel Compute Runtime library) fixed in 24.04.1? Or TBD?
I’m in a weird spot. I’m running 23.10 because I needed 23.04 to get my i9-13900 working. Waiting to upgrade to whatever is the latest compatible LTS.
Thanks!

As I understand 24.04.1 , it will have the 6.8 kernel. That fixes a whole bunch of pure-CPU issues.
We have been doing really well on two versions of PMS (across the board eval)
1.40.2 (pre build 8555) works great for folks EXCEPT GeminiLake and ApolloLake. Build 8555 fixes those CPUs.
Since then, the only complaints I’ve had are from those who got lucky with their Arc GPUs during those releases.
Our lab machine is a 13th gen as well (15-13400) and is what we QA all this on.
You should be in good shape.

Let’s say I upgrade to 24.04.1, run the 6.8 kernel, and I hypothetically have issues. I can just downgrade just the kernel, run the 6.5 kernel on 24.04.1, and it’ll run fine, right?
I’m eager to jump on 24.04.1 because 23.10 is EOL as of July. Thanks!
You can downgrade the kernel if you like.
I don’t know how much you have in /home but, if you’re able, I always recommend this type layout. It separates home directories from the OS so you’re free to change the OS version whenever you want as well as save PMS and other files from OS install to OS install.

Hello,
i have issues with my Transcoding as well, using Ubuntu 24.04 ofc… but i use it for reasson, i have Intel Reptor Lake U cpu, that is properly supported i belive from kernel 6.7 so downgrade is not option for me…
So far, from what i found… Plex see my GPU as unknown / intel and do not use it… when i searched some solution (drives me mad, as jellyfin can use HW transcode but i want my beloved plex), vainfo on host machine load OK and show a lot of profiles, but when Im in docker machine, vainfo failed to load

And im stuck atm… Im using new Intel Core 3 100U CPU
OK, just for fun i tried to build new docker image based on Ubuntu 24.04, now VAINFO show me correct information, yet plex still show my GPU as unknown/intel and HW transcode is not an option…
Yet i know the card is there and i plex user can use it

EDIT: I managed to get the by-path into /dev/dri, yet no difference, HW Transcode still missing 
I’m able to transcode a 1080p video down to 480p but the video becomes fuzzy/blurry (like the colors are bleeding out like a highlighter). Also think there are some issues with some native 480p content having higher bitrates then they should (and I need to reduce the bitrates in order for it to be playable smoothly)
First we need to figure out why your hardware is wrong.
After that, native host and subsequently containers will fall into line
let’s see the real hardware.
here you see the AMD and Intel in this machine

It is ASUS Nuc with integrated GPU, CPU Is Intel Core 3 100U (14gen Raptor Lake U)

Being a RaptorLake, the Intel Arc GPU should be showing.
It is not.
It should be showing a lot more of the hardware – as from this page
You’re only getting the VGA adapter . There is a ton of kernel drivers missing.
When is the last time you updated the init-ramdisk ?
It is 3 day old ubuntu install…

3days? Then not much time is lost.
I would recommend you grab Ubuntu Desktop 22.04.4LTS, the iso will come with 6.5 kernel from the get go, RaptorLake supported.
PlexInc official docker image and use
image: plexinc/pms-docker:1.40.2.8395-c67dce28e
This specific CPU I have, by Intel pages is supported since 6.7 kernel (tried boot different distro with 6.4 and it even do not boot, not see ethernet or wifi etc…) It was released 1Q24… I can give the ubuntu 22.04 a shot, but i do not belive it will work to be honest…
Well, if you look at this then yeah, 3 days is OK, but i sleep in that 3 days like 5 hours total 
I was thinking about move to kernel 6.10, if that helps, but not have time for that experiment so far
It is RaptorLakeU (refresh) by Intel site, and support is added on 6.7, see https://www.phoronix.com/news/Linux-6.7-drm-intel-ne
Dig into this a bit more… So Core 3 is Raptor Lake Refresh, 13th gen cpu that was added into kernel 6.7 but drivers alone is available for Ubuntu 22.04 from Intel. What was confusing a bit, they speak about Core X as 14th gen, but Core 3 (Raptor Lake U) is same 13th gen, only rebranded to fit new 14th gen cpus lineup… Why the hell make things easy for consumers.
I will try prev version of Ubuntu and see how it will fit
My NUC arrived.
I’m a bit hampered right now as the migration did not go as expected.
( Major display driver issue which will FINALLY be fixed in the 6.8.1 kernel )
With luck, I’ll be back to two monitors then.
I agree with grabbing the 22.04.4 LTS upgrade (bring it fully up to date)
When 22.04.5 is released, a number of bugs will be fixed (like mine)
Have any of you tried this? It’s a lot of work on the transcoder.
https://forums.plex.tv/t/subtitle-burn-in-improvement-test-build/884481/2
You know you can try “mainline” in Ubuntu to update kernel, right?
Btw: 24.04.1 should be released in 9 days…
