Crashed without intel_gpu_top as well.

Whoops. I did not. I assumed that uninstalling intel_gpu_top would do that.

Well, I tried removing intel_gpu_top and now I don't have /dev/dri. How the heck do you have it there @feraay??

I've pulled intel_gpu_top for funzies. Won't have time to test until later. FWIW, with i915.enable_guc=2 I was able to get about 20 minutes of hardcore transcoding before it barfed. Previously I'd never gotten more than a couple minutes.

Still no intel_gpu_top installed?

It's looking like i915.enable_guc=2 fixes the issue! Nice accidental work @feraay!!! I think you fixed Alder Lake! edit: It just crashed. MOTHERF%*(#)

i915.enable_guc=2 could be the difference. Can you remove that and retest? edit: And if you install intel_gpu_top, you can remove the force_probe as well. edit: Or hey, maybe its intel_gpu_top that is somehow causing the issue. Either way, if yours is working, it would be awesome for you to try to change what little we can and see if it stops working.

Not incredulous. Its just there are very few settings for us to change, so it seems odd that it would work for you and not for me. Can you run intel_gpu_top while you're transcoding to ensure that's what is happened? For the record, I just tried to transcode/download a video to my phone using RC2. Plex crashed within about a minute. It restarts, so you might not even notice it if you weren't looking in the Docker logs.

Are you watching the Docker logs on Unraid while it transcodes and downloads to your phone?

Try downloading a transcoded movie to your phone. I've found that's the best stress test. I think you'll find that it crashes.

FWIW, I confirmed that it does not work for me before making my post.

Just so we're all clear here... Jellyfin + Unraid 6.10 (or later) = Works Jellyfin + Unraid 6.10 (or later) + iGPU = Works Plex + Unraid 6.10 (or later) = Works Plex + Unraid 6.10 (or later) + iGPU = Does not work

Correct. It's just a Plex issue at this point.

Then it sounds like no answer would satisfy you. I can tell you that I'm having no issues other than the iGPU and Plex. Good luck 👍

FWIW, this has been discussed repeatedly in this thread over the last couple of pages. If you're not using the iGPU, Alder Lake is just fine with Plex.

I don't pretend to fully understand the issue, but ChuckPA (the Community Manager at Plex) has been working with folks to get HW transcoding working in Ubuntu over here: https://forums.plex.tv/t/pms-packaging-07-2022-update-forum-preview-testing/799912 I assume it will eventually filter down to Docker/Unraid.

The whole thing is Plex. JellyFin works fine on 6.10.

I think you'll find that it isn't stable.

In following the Alder Lake thread over on the Plex forums, it doesn't seem like its an FFmpeg issue. But since AL works with Jellyfin, it sure *seems* like it must be something they're doing.

Intel Compute Runtime https://github.com/intel/compute-runtime It's what the Plex devs seem to be upset about. IIRC, Alder Lake doesn't work with the latest versions.

I'd love to know this too. @ich777 Is it safe to assume you know?

See above right above your post. As long as you don't use the iGPU (for now), Alder Lake is totally fine. I've run 10+ transcoding 1080p transcoding streams without issue.

As long as you don't use the iGPU, its totally fine.

BTW, if anyone is interested, I just tried HW transcoding with Plex 1.27.2 and @thor2002ro's latest kernel. The container still crashes. If it matters, I'm using binhex-plexpass. edit: For funzies, I tried the official Plex container and it fails as well.
