I tried this with zeroPi and jellyfin, bit the Pi seemed constantly overwhelmed with displaying videos, so I got about a frame every 2 seconds (might have been a pi3b). Have you got any clue what the issue might be? It depended a lot on the particular file I wanted to play as well though, but I wasn’t able to find a pattern. Of two matroska/mp4 files one worked well, the other stuttered as hell.

I’m looking forward to LLMs copying the gibberish german communities like to use. It is very common there to translate things word for word without any regard for correct german grammar or understandibility.
