HW Tone Mapping not working on Windows 11

I’d just like to add that Jasper Lake does support HW Transcoding + Tonemapping officially , as it also works on Jellyfin too, I tested it side by side

:: Edit ::

I think I just solved the issue. I enabled HEVC video encoding and now it’s using hardware acceleration, the video starts almost immediately, no buffering, low CPU/GPU usage in servers task manager. I know this makes very old devices that can only decode H264 not work but I won’t ever be using a device that old.

This seems like a bug no? Why would it easily support hw transcoding and hw tonemapping to HEVC but not H264?
