@chris_decker08 should I be staying on version 1.40.1.8190? Plex server is prompting me to update to Version 1.40.2.8273. Currently doesn’t seem to be working for me anyway
@ataribaby 1.40.2.8273 should be perfectly safe, however it does not yet include support for intel tone mapping on windows.
Right, well, i guess I’ll take the update and keep an eye on this thread for your next version.
Could we maybe get links to the different versions of this that are coming out? It seems some of us are having better luck with whatever version for whatever reason. I know at least from my tests that the Plex Version: 1.40.0.8074 worked way better for me then the others that have been released.
each new version is an iteration, so even if I post old links you would need to never update… The latest version appears works for 95% of users so my current plan is to fix the issue with RDP then include the improvements in the main release schedule. Hopefully more data points will help me pinpoint the few remaining issues.

@kleatus27 can I reach out to you in PM to have you run a couple variations of the transcoding command on the command line? it may help narrow down the issue.
Curious to know what this means for Core Speed Requirements for 4K Transcoding…
I know at 1 point it was recommended to have a CPU Capable of a minimum Core speed of 3.7Ghz to keep up with the tone mapping load, audio transcoding (If Necessary), and sub-title display (If Necessary).
So are we saying now being able to off load Tone Mapping to the iGPU, processors with a much slower core speed than 3.7Ghz are able to handle 4K Transcoding? Presumably it was the tone mapping that required faster core speeds than Audio & Sub-Title Transcoding.
Yeah sure, I’m able to.
Hello,
Can you confirm that the i7 12700 processor is not supported ?
Can we get an update to this preview? It’s now several versions behind.
I was waiting until we had addressed all known regressions in 1.40.2 before creating another test build (We are likely now at that point). I was also hoping to hear back from my contacts at intel as to why ADL-N chips give the error Error running VPP: unknown error (-1) (this also happens on baseline ffmpeg).

Thank you for the update. Much appreciated.
Ready to order a couple Arc cards to test with as soon as this is merged into the regular beta or mainstream channel.
Hi. Was going thru the full thread before I was going to post, but when I came to your latest reply, felt I wanted to chime in.
I run multiple PMS at home:
- i7-8700K+GTX1650 on Win 11 Pro
- i7-1165g7(Intel Iris XE) was on Ubuntu 23.10 until I upgraded to 24.04 LTS Beta and broke Hardware Tone Mapping → rebuilding the server as a dual boot Win11Pro/Ubuntu 23.10
In a rush to get a 2nd server back online, I commissioned a Beelink N305 setup with Ubuntu 22.04 LTS plus the latest Linux Beta of PMS, since the current Stable seems to have Hardware Tone Mapping broken on the latest Ubuntu 22.04.4 LTS.
Just now, I finished wiping my i7-1165g7 and during rebuild decided to set it up dual-boot (Win11/Ubuntu). Currently testing the 8190 preview build on Win 11 Pro (downloaded it tonight).
I confirm Hardware tone mapping works (CPU hovers at around 20-30% utilization and Intel IRIS Xe GPU is at 80%). No buffering during video playback. Forcing a 4K HDR to transcode including Tone Mapping to play on my Nvidia Shield Pro client that is setup to output in 4K SDR.
Regarding the image: it is definitely darker then when I play the same file on either the i7-8700K+GTX1650 or on the N305 that also has Intel UHD graphics using the same Nvidia Shield client.
Although Intel provide no way to adjust brightness, why is the same file brighter when running under Linux using the same GPU (I refer to when I was using the i7-1165g7 with Ubuntu 23.10 + Mesa drivers from Intel, and the previous PMS build that still had functional Hardware Tone Mapping).
Also, am I missing something in the form of the Intel Video Processing Library (do I need to download/compile/install the dispatcher and the runtime), in order to make the preview work properly?
Almost forgot: I want to say a huge Thank you to all the hard work you have put in to make this work once more on Intel iGPUs and Windows. Also, i’d like to help out in any way possible. Please let me know if there is anything I can do to help.

Keen to test this once available - I have an i9-13900TE that has a UHD770 that it would be amazing if this worked with
@Karim_Q Tone mapping is darker on windows due to the fact that this windows build uses the built in tonemapping capability of the CPU while on linux we use hardware accelerated opencl tone mapping (which can be configured). Hopefully someday we will be able to have both options on both platforms. Also, we are aware that tone mapping is broken on newer linux kernels, there is a bug in the intel opencl library which intel has acknowledged but not yet fixed (that I am aware of).
@AndrewJ41 this should be compatible with your device.

I don’t see why not. The 12700 is a standard ADL-S desktop CPU that’s listed as supported on the first post.
Do you know the likelihood of being able to use hardware accelerated opencl at some point? Like is this some sort of Intel driver/sdk limitation or work that needs to be prioritized in-house?
Also, have you seen poor ARC transcode quality, such as blockiness? I get much better results with my CPU, but it can’t handle transcoding HDR content. Even 1080p is bad. Here are clips from a 1080p transcode:
ARC 770:
Intel 9600K:
Some scenes are better and some are even worse. Do you have any control over this quality?
out of curiosity, do you have resizable bar enabled on your system?
yes, resizable bar is enabled
