4k HEVC Playback Issues in Browser

Alright - So apologies because I'm pretty fresh when it comes to this so let me know if you need something else

I've got my media stored on a Synology D423+ with internal Intel Celeron CPU
- DSM 7.2.1
- 18gb of physical memory
- I did set up hardware acceleration when I installed the Jellyfin in container
Here's the YAML config:
