Of course I have been down the rabbit hole. The software is wrong. Give me an option to bypass re-encoding, and instead of failing based on diagnostics like it does, just play the darn file the best you can. I only have so much patience and I prefer living with a samba share to play it in the exact same mpv player without problems rather than fighting software over something that is so simple and fundamental to a video player.

Yeah, I can 100% understand your frustration. It’s also a bit opaque as to why it’s re-encoding.

That said, we are a family so I can’t get everyone else to stream to mpv, so Jellyfin works better for everyone. mpv is also a great piece of software, plays everything!
