HDR HW Tone Mapping broken again

[Rainzzzzzz]

---

Expected Behavior

HDR Tone Mapping should still use hardware transcode

Current Behavior

When HDR tone mapping is enabled, software transcode is used

Steps to Reproduce

1.Add the /dev/dri device to the container
2.Enable HDR tone mapping
3.Play something with HDR and force it to transcode
4

Environment

Unraid 6.10.3
I5 11 gen
How docker service was installed:
Unraid app menu

Command used to create docker container (run/create/compose/screenshot)

Close it by mistake

All HDR transcode are software now
But non-HDR content goes to HW perfectly

[Rainzzzzzz]

Has something to do with that

Same for me until I reverted back to 1.27.1.5916-6b0e31a64-ls122

Edit:

On the plex forums they mention the following:
(Linux) Improve Intel Compute Runtime version detection in packaging on Ubuntu 22.04 and newer.

Maybe that has something to do with the problem. Even though I'm on Ubuntu 20.04.

Edit 2:
According to https://www.reddit.com/r/PleX/comments/vny30q/new_beta_pms_version_available_12725929a806c5905/ie9wh8b/ the intel change was not even included. So I have no clue what causes it to break.

Same issue, problem is back just like before. With tone mapping enabled, no HW transcode on HDR content. 9900K here. Turning off tone mapping fixes it

The only way is to revert to 1.27.1.5916-6b0e31a64-ls122 and lock it there
Work fine since the rollback

This worked for me! My CPU was hurting bad.

I have manually installed the intel compute-runtime packages: https://github.com/intel/compute-runtime/releases/tag/21.49.21786 inside the container and hw transcode with tone mapping is working again.

Can you guys test this build and let us know if it works? lspipepr/plex:amd64-1.27.2.5929-a806c5905-pkg-bbd93429-pr-319

Hey @aptalca, I too have the hw tone mapping issue which is resolved with the image linuxserver/plex:1.27.1.5916-6b0e31a64-ls122, allowing me to transcode or optimise 4k hdr video using hw acceleration on my intel core i7-1165G7. I tried your image lspipepr/plex:amd64-1.27.2.5929-a806c5905-pkg-bbd93429-pr-319 out on the same file with the same optimisation settings and see that it does not fix the issue, falling back to sw encoding. If you want more details let me know.

[aptalca]

@patrickthescriptwhisperer can you repull that image and try again? I pushed an update

Thanks

[patrickthescriptwhisperer]

sorry that took a minute, just wanted to double check the cpu usage between your latest and the original image I was tied to. The latest pull of your image appears to be working well 👍 the full transcode still takes a little while so I will leave it running and I can spot check the output when it completes. Thanks for putting that together.

tone mapping seemed to work well; no weird artefacts, no dimming, thanks again
