@Linerjoe do you have the Intel compute runtime packages installed? On PMS 1.22.0.4163, a i7-10700 should do hw transcoding, including HDR tone mapping, once you install them and restart the PMS service.
I did not! I just installed them, and restarted PMS. That seemed to help, although CPU usage does appear higher than previous.
Before, transcoding a 4k HDR title to 1080/flac (Chrome) would use all 8 CPU’s, pushing usage to 100%. Now it’s about 30%. Most of my watching is done on a Shield Pro, which doesn’t require any transcoding, so I really didn’t notice this issue until I was doing some testing on some webhooks, so I was starting/stopping from a browser (triggering transcoding).
If you’re using subtitles (PGS, VOBSUB, DVDRIP, or just burning in SRT), you will burn CPU cycles on that.
The special libraries do not yet provide HW burning of subtitles.
No subtitles.
May I have the DEBUG logs please which capture this?
- Start playback
- Play 20-30 seconds
- Stop
- Wait 20 seconds for logs to flush to disk
- Settings - Server - Troubleshooting - Download Logs
- Attach the ZIP file here for me to review.
This issue persists with PMS 1.22.1.4228-724c56e62.

Same for me as well - i5-10600K with Intel Compute runtime installed.
Would you all be kind enough to please create some fresh logs for the transcoder team to come grab?
Best logs to provide:
-
Verify DEBUG logging enabled, VERBOSE logging disabled – SAVE if you make changes
-
Restart PMS
-
Wait 2 minutes
-
Recreate the failure by:
a. Start Playback
b. Let play 20 seconds
c. Stop Playback
d. Let sit idle 20 seconds for logs to flush to disk -
Download Logs ZIP file (Settings - Server - Troubleshooting - Download Logs)
-
Attach that ZIP file here (in thread upload)

That’s what I’m seeing to.
I wrote it up yesterday and gave it to Engineering.
IMHO, it’s a regression but time will tell
My recommendation for now is to downgrade PMS version
Today’s Challenge Question:
Is everyone who’s having problems ALSO running Ubuntu 20.04 or the Debian 10?
Ubuntu 19 and older will not cut it here.
Same goes for older Debian versions.
There is insufficient kernel support

You guys are killing me! 
I run a Redhat-based system now but still a NUC8i7-HVK.
I need a working ESXi VM with i915 passthrough (which I’ve not figured out yet how to do).

Everyone – Please also include which CPU you are using – EXTREMELY important to help my sanity (also trying to keep -10xxx CPUs sorted)
IF I understand everything correctly –
- All Intel processor SKUs below -9000 will continue to use Beignet
- All Intel processors SKUs above -9000 are to switch to Intel Compute Runtime.
This is a change Engineering put in (which I’m still trying to get clarification on while learning how some of this stuff works).
