Hurde

Requesting bluez support for Bluetooth usage.

Yes, 4K Remuxes, (most) with Dolby Vision or basic HDR.

I installed Intel-GPU-TOP on my machine and got HW transcoding (with tone mapping) working with my i3-12100 in Plex. However, using the included PGS subtitles absolutely kills my server (while hw transcoding) and the video will buffer a lot, so I'll have to download .srt subtitles for my media as they work without any issues. Is the issue with burning PGS subtitles related to just Plex not liking those subtitles, my CPU being too weak for burning them or what? Should I expect my machine to work with them at some point, or should I just download the .srt subtitle files for my media? Most of my media is played with local direct play on Nvidia Shield Pro, so the included PGS subtitles are not an issue. But around 10 % of my usage is remote viewing, which is why I wanted to get hw transcoding working on my machine.

Do you know if there is a specific issue ticket/thread on the Plex forums related to this? Or something else I can follow for possible fixes and updates.

No idea if this is related to the same issue on Unraid: The root cause of the failures for all versions above 20.04/ ICR 21.49 has been identified. https://forums.plex.tv/t/plex-media-server-on-ubuntu-21-10-with-intel-12th-gen-alder-lake/768123/12

It looks like that 6.10-rc4 with 5.16 kernel could be behind the corner "soon". I'm not that familiar with Unraid time, let's hope that it is not the same as Valve time. Let's hope that it allows full HW transcoding with HDR tone mapping & x265 support.

Have you tried HW transcoding HEVC/H.265 material with HDR tone mapping enabled? I think that is currently the only thing that doesn't work correctly.
