avc/h264 at greater than 4k - exit - 2024-03-27
I'm trying to play some VR files that have a resolution greater than 4096x4096.
The server has a 12th-generation Intel CPU for hardware acceleration. I've tried both QSV and VAAPI and both give me the error below.

With hardware acceleration the files play, but obviously, the CPU usage is off the charts.
Is there a setting I need to change to allow greater than 4k encoding on jellyfin?
Thanks

Negatory. It is a hardware limitation. Keep in mind that Quick Sync, NVENC, etc., are fixed function capabilities. You trade flexibility for speed. Also says it in the log.
Code:
[h264 @ 0x5635c4050380] Hardware does not support image size 6000x3008 (constraints: width 0-4096 height 0-4096).RE: avc/h264 at greater than 4k - exit - 2024-03-27
So my options are to resize the files or will a different format like h265 work?
Appreciate the reply!

I think HEVC would work. The Quick Sync wiki says that Alder Lake supports 8K HEVC. Which that file is smaller than.

Awesome thank you. I will post back if that works in case anyone else runs into this in the future
