Fatal Playback error

[hqhma]

I am brand new to jellyfin and I have been able to get it working flawlessly. I just recently threw in a new TV show and I get a fatal playback error. It seems to have something to do maybe with FFMPEG judging by the log but I don't really know. How can I go about troubleshooting and fixing this?

Can you post the log, please?

I am no expert on ffmpeg, but my best guess is that it is trying to do some sort of hardware transcoding, but is unable to find the hardware needed (i.e. a GPU with the right drivers). Have you been able to use files with the same format before (i.e. mkv container, streams with codecs of vc1, truehd, ac3, and PGSSUB)?

What are the specs of your server, and how are you running Jellyfin? If using Docker, post your compose file.

I have been able to play MKV container and a VC1 codec before yes. Same with truehd and ac3 audio

Update: I just read somewhere that ugreen NASs have issues with VC1 so this might be the issue.....
