I’ve been a Plex user for several years. The last few years, I’ve been running my Plex server on an old AMD FX-6300 system and it’s been doing good for my needs until recently. It had troubles transcoding 4K HEVC streams to the point where they were unplayable. I read up on hardware transcoding usin…

@ChuckPa Not to thread jack too much, does the fix listed above work for 11th gen? I have an I7 11700 and I’m having the exact same issues described. HW transcoding works with everything but 4k HEVC. Is this a Plex issue, driver issue, or both?

@maasi --and to everyone following along, I’ve been doing a lot of research. Killer points here: Kernel 5.11.11 or better – and stable – (which the i915 does not yet appear to be for the -11xxxx) RPM users will need compile themselves from Intel Compute Runtime GITHUB RPM users - also the equ…

First off, appreciate your response on a Saturday - you’re the man! Thanks for the insight on the situation. I guess I will be sitting tight. To answer “the real question”, ask my family members who refuse to watch at native quality! I try to educated where possible but it is sometimes a futile eff…

You could be hard headed about it :rofl: “My server – My rules” … then turn off transcoding and tone mapping :smiling_imp: I just got 1440/42 Mbps internet a couple months ago. This is the first time I’ve actually been able to stream to family. I did lay down some rules. There is a…

Confirmed working on Ubuntu 18.04 LTS <3 TL;DR for Ubuntu: sudo add-apt-repository ppa:intel-opencl/intel-opencl sudo apt install libze-loader libze-intel-gpu libigdgmm11 libigc intel-opencl-icd Details from what I understood in that thread: It seems at some point the HDR tone mapping was added…

This was perfect, fixed my HW transcoding issue with regular HVEC files. I was weird it would HW transcode DV , MP4 but not regular HVEC/HDR. Once I followed the below instructions everything is HW transcoding. … Next problem up. the dam green and red color for the DV transcoding…

There is not yet any DV color mapping to H.264 space. AFAIK, It’s on the list of things to do.

@ChuckPa Hello, since the thread is already older, I would like to know what the current status is. Does the 10Gen. as well as the 11Gen. 4K HW Transcoding + Tone Mapping work under Ubuntu or should I rather buy an older NUC8 with Coffee Lake-U and Iris Plus Graphics 655 ?

10th Gen works very well with Intel Compute Runtime runtimes installed. 9th and below uses Beignet. You’ll find this release of the package refines / fixes the detection of the CPU and which packages should be installed. There is work (AFAIK) work underway for the 11th Gen CPU ASICs. To ful…

I built a new Plex server recently with i5 11400 instead of i5 10600. I’m kind of regretting it with all QuickSync / transcoding woes. But I hope eventually Rocket Lake will have a solution.
