Can I just say… this is a refreshing thread! So much collaboration between Plex and the user community to investigate an issue.
I picked up a NUC 11 (i5PAK) the other day. I’m coming from a lifetime of Windows (I like tech, but at the end of the day I’m just an “end user”), and I thought “I want 4K HDR Tone Mapping, and Windows sucks at this! So, I’m going to buy the latest and greatest NUC, install Debian, and it’ll smash HW transcoding!!”. Nope… I can’t even get Debian installed, let alone Plex. Now I’m reading all these HW transcoding support issues.
Sooo… I give up. As per the above comment, and before I go ahead and try it all out, what’s HW transcoding like on Windows on Iris Xe? I know HDR Tone Mapping has reduced performance, but can it still work with multiple transcodes (i.e. 1-2, instead of 4-5 like on a NUC 10 with Linux)?
Don’t give up man! Can be a little frustrating sorting all out but once you leave windows, there is no going back! HW transcoding will be updated and fixed, actually in the other thread they already got it, it’s just a matter of time that it will be released to us all.
I’m not an expert, what I understand is they fixed the 10gen transcoding with new packaging and paved the way to support 11 gen once the “upstream” issues are fixed… @ChuckPa is working hard on this, they will get it eventually. If I’m mistaken please correct me.
We are dependent on the upstream (kernel ( i915 ) work that needs completing ).
This is unfortunately one of those COVID fatalities. Hardware was done but nobody could go into the labs and work on the hardware/software together. It really lengthened the development time for RocketLake support
Yes 10th gen is fixed, just nothing there to currently help fix the crashes on 11th gen tiger lake range. Just plex side of things is ready when kernel is fixed.
Rocket lake I’ve seen people say they have it working, but sadly that doesn’t help either.
Thanks all for confirming! Any any details on HDR Tone Mapping in Windows before I spend some time installing and testing (answers so far seem geared towards Linux)?
I might offload the NUC 11 to a family friend (whose wanting a new machine anyway) and wait for better support.
I still want to try Linux… I might give it a bit though before this rookie starts having a bash at it.
Is there any good alternative on the AMD side?
I’m curious on which level of Plex performance AMD low-powered Ryzen CPU with Radeon graphics compares to Intel gen 11 QSV, and what can we expect on Plex support for HW transcoding.
Just a follow up to this… I installed Windows 10 20H2 (OS Build 19042.928) and immediately installed the latest Plex Server. Signed into Plex Pass, enabled HW acceleration and can confirm that Plex Server will not HW transcode a 4K HDR video file with Intel’s Xe Graphics.
Plex Media Server: 1.22.3.4392 Intel Graphics Driver: 27.20.100.9466
Unlucky for me… I do have an RTX 4000 awaiting use so I may just have to get a 10th Gen Intel CPU (lower spec) and re-try Debian with CUDA acceleration.
I’ve got a recipe (with thanks to @ChuckPa & @RoadRacer12) for a setup that will successfully hw transcode on i5-11500 on Ubuntu if you’re interested. It does not support HDR to SDR tone mapping, yet.
I have options i915 force_probe=1 enable_guc=2 in my /etc/modprobe.d/i915.conf file, but force_probe=1 shouldn’t be needed for Tiger Lake on kernels >= 5.7 according to this page.
force_probe=4c8a is for desktop CPUs, we have mobile ones in NUC 11.
I have a NUC11 and just got the new Proxmox 6.4 iso, have a USB NIC so that it gets an address, but I’m totally stuck trying to upgrade to the 5.11 Kernel to make this thing go!
Followed some instructions here:
But it just keeps telling me “Unable to locate pacakage pve-kernel-5.11”
A couple of decades working troubleshooting Windows machines does not make up for my relative Linux noobness but I’m sure there must be something simple I’m missing!
Hmm, not REALLY off topic though is it? I want to use Proxmox to host Plex so I WILL run into the HW transcode issue if/when I get it installed and I’ve battered my head against a lot of forums looking for answers.
And @ChuckPa is by far the expert on this stuff here judging by all the posts I’ve read regarding Proxmox and I don’t see any similar threads that are open.
I’ve already looked at the link you gave and I’m stuck, but I’m going to start from scratch again tonight…
This is for getting it working in the first place, not supporting installing an OS prior to getting it working.
Also depending how you plan to run it on proxmox it’s likely unsupported at this point as well.
If you read this whole thread I’ve already been told the same thing and switched to bare metal OS install to be able to actually provide insight into this on a supported platform.
