I tired loading the video and same thing happened. This log is from right after it failed.

Can you clarify your setup?  You label your Ugreen NAS as the "server" then listed an Intel CPU.  Is the Ugreen NAS just storage, or is Jellyfin running on it?  Or is Jellyfin running on the system with the Intel CPU?

Also, I need your ffmpeg log since it appears that it is failing to transcode for some reason.  If your Jellyfin server is running on the Intel based system, can you also share your docker compose for the Jellyfin container?

Server Specs:
Jellyfin on Docker - 10.9.11
Server - Ugreen NAS DXP6800 Pro on there os
CPU - i5-1235U 10 Cores, 12 Threads
Ram - 8gb
