2GB runs fine for a simple playback client device. If you want to run a load of container/server services in the background then 4GB or perhaps 8GB will be more suitable.
So all seems fine ![]()
Except the 4k video that stutters.
Might actually be the 2GB version that is too low specced?
Idea: RPi 5 with 8GB (~85€) - Raspberry Pi M.2 HAT+ (~15€) - some old NVMe SSD I find in the office cabinet...
Should give much better performance disk-wise and maybe also helps with the issue of the 4K decoding?
