Hardware Acceleration Issue on N150 Processor

[Unstirred6783]

I'm using a Beelink S13 Mini PC Intel N150 Processor.

I installed Debian 12 on the PC and also Jellyfin via the Jellyfin website's official instructions.

I then made sure the Kernel was up to date, the Intel drivers were installed etc via the non-free backport repository.

I installed Mesa, Intel Graphics, Linux Firwmare, etc. 

Then I went into my Jellyfin dashboard and enabled Transcoding Hardware Acceleration via Intel QuickSync (QSV)

My settings look like this:

QSV Device:
/dev/dri/renderD128

Enable hardware decoding for
H264  
HEVC  
MPEG2  
VC1  VP8  
VP9  
AV1 
HEVC 10bit  (The only one unchecked, as this is the only one that caused me issues)
VP9 10bit 
HEVC RExt 8/10bit 
HEVC RExt 12bit 
Prefer OS native DXVA or VA-API hardware decoders

Hardware Encoding Options:
Enable Intel Low-Power H.264 hardware encoder  
Enable Intel Low-Power HEVC hardware encoder

My problem is: 
If I check the "Enable Hardware Encoding" option, it causes me to get a "Fatal Playback Error" that states the following: "Playback Error Playback failed due to a fatal player error."

If I go and uncheck the "Enable Hardware Encoding" option, then my playback works but I suspect it's not using QuickSync and it takes forever to seek etc.

Has anyone had this issue before, what can I do to troubleshoot this / fix it?

Thanks!
