I’m setting up a Plex Server for a friend. The system is an Intel NUC 11 which supports Intel Quicksync. Plex is installed natively in Debian 11 but when I try transcoding, hw transcoding is not working as shown in the dashboard screenshot above.
I have the same setup but with a NUC 10 and everything is working. @ChuckPa do you have any ideas?

Are the Intel compute libraries still needed? I thought they weren’t anymore? I mean the installer doesn’t complain about them anymore and I read in another thread that the newest Plex version don’t need them anymore. I don’t have them installed in this NUC 11.
@anon18523487 please help
The user-installed packages are no longer required.
PMS now includes the Intel Compute Runtime libraries it needs
You can confirm by looking in the “Drivers” directory under “Plex Media Server”
Ensure DEBUG logging is on.
Make certain you aren’t trying to play something with subtitles in it.
Attempt the playback in the browser (Plex/web).
Stop playback
Download the logs.
Attach here. I’ll look at what it printed
I wasn’t sure if you wanted the debug logs for the PMS or the plex web client but here’s both. I played Black Adam for about 40 seconds before I stopped the playback.

Thanks for the logs.
Your server logs (sorry for not being specific) show you’re getting HW transcoding

Basic questions:
No worries.
#2 reminded me that a headless server should have a dummy HDMI device plugged into it to avoid any GPU issues like this. So I thought that was the issue. I plugged in a real monitor (just to test), restarted the server, and it still didn’t HW transcode if I have tone mapping turned on.
You can have the GPU disabled (no display) but still see the QSV ASIC
You have:
Ok, so what is wrong with the system then? With my NUC 10 PMS, HW transcoding with tone mapping works whether there is a display plugged in the HDMI port or not. With this new NUC 11 PMS, it doesn’t work for both scenarios.
Install PMS 1.29.2.6364 and retest
Can I install this lower version on top of the existing latest version without any detrimental effects?
Yes. you can
@ChuckPa you have any other ideas by any chance?
@ChuckPa just wanted to remind you again on this. Do you need more troubleshooting from my side?
Look at your transcoder temp.
/dev/shm/transcoding
Do you have that created by shell script at each startup?
You should be setting (if you have enough ram) /dev/shm.
PMS will create what’s needed below that.
Also recommend, CUDA 11.x drivers (470 → 515.86.01) for PMS 1.29.2
PS: been sick here and took weekend off.
No, I don’t but I use the same /dev/shm/transcoding path on my NUC 10 and Plex always just create the folder for me on the fly. Is this a significant issue that I should just use /dev/shm instead?
How do I make sure that the CUDA drivers I have are of that version? And why do you recommend the older 1.29.2 instead of the newer 1.30.x versions?
No worries, hopefully you’re better now.
