SOLVED: Jellyfin doesn't work

[supertanno]

Code:

.....
[20:56:17] [INF] [1] Main: Program data path: /home/supertanno/jellyfin
.....
System.ComponentModel.Win32Exception (2): An error occurred trying to start process 'ffmpeg' with working directory '/home/supertanno'. No such file or directory

Does jellyfin have permission to that directory?

I don't think so, I remember this also being an issue when I initially tried to put my media in /home/supertanno since Jellyfin couldn't access that. 

How can I fix this? I know that doing a CHMOD 777 on the user directory is not a good idea, but I don't have any other ideas for how to fix it.
