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…

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.
