[Intel 12th generation Alder Lake / Hybrid CPU]

Hello everyone, plex has been tested in beta. Except for HDR, there are basically no problems with transcoding settings. But, emby, have you tried? I have tried several times, but 4K video transcoding seems to be impossible. 1080p and below resources have been tried several times, but it is OK. Have you ever encountered such a problem?

Just to share my experience.

 

Using an i3-12100 on a Z690 motherboard on unRAID 6.11.0-rc2

 

I now have HW transcoding working perfectly, the only thing that doesn't work is tone mapping.

 

With this -

 

echo "blacklist i915" > /boot/config/modprobe.d/i915.conf

 

Intel-GPU-TOP

 

GPU Statistics 

 

and /dev/dri in the official Plex docker container.

 

No other changes from default configuration.

 

I've played a 4K home movie in Plex, transcoded down to 720p without issues.

 

I've also converted it to a lower quality and downloaded it to a android phone with no problem either.

 

Both definitely using the GPU as can see low CPU usage and high GPU usage throughout.

 

I've had no crashes or errors in either my system or container logs. 

 

If I enable tonemapping, I don't get any errors or crashes, but instead of using the GPU it uses the CPU.

 

Hope this is useful to others!

Thank you for sharing.
There is a little doubt, isn't it necessary to install Intel GPU top in version 6.11?
In version 6.10.3, I have done the following operations: installing Intel GPU top, shielding i915 driver, and adding kernel display to plex container.
Unfortunately, the plex hard solution still crashes. I cannot select "use hardware acceleration when available" and "use hardware acceleration to encode video" at the same time. But I can choose HDR and "use hardware acceleration when available" at the same time.

@feraay Do you have both "Use hardware-accelerated video encoding" enabled and "Use hardware acceleration when available" enabled in Plex, or just the latter?

 

Plex crashes due to GPU hang within about 5 minutes when transcoding with HA video encoding enabled along with "Use HA", but doesn't with only HA acceleration enabled.

I have tried unraid 6.10 and 6.11 RC2 many times. If I only choose "use hardware acceleration when available", plex will not crash. If you select "use hardware acceleration when available" and "use hardware acceleration to encode video" at the same time, the first transcoding succeeds, and then the plex will crash when transcoding later. My hardware is 12700 and tuf b660m.
