Jellyfin - Playback failed due to a fatal player error - Tmdickson66 - 2025-11-05
Hello, I am running jellyfin on a ubuntu VM on proxmox. jellygfin is set up through a docker container. I am having trouble playing certain media files. Some files work completely fine while others won't play at all showing 0h 0min duration, with an fatal playback error. I was able to play the files that aren't working in vlc media player outside the server. It seems like there is an invalid argument in the file name per the error, Error opening input files: Invalid argument. I am not sure what it is though as I see no difference between other files that work.
