transcoding settings

[the-bort-the]

I also have an Alder Lake CPU with Jellyfin installed as a docker container on Debian. I have followed the thread and believe I've checked all the same boxes, but I'm seeing a lot of pausing/freezing/buffering during playback. It's much worse than just disabling the encoding/decoding. I do see, via the top command the CPU% is way down from when hardware acceleration is completely disabled, so there's that. I've included some playback information as well.

I'm struggling to understand how things could be different. If you want a new thread, I'm also happy to open one. Adding some of the information that was asked of OP in hopes there is something I've missed.
