SOLVED: ffmpeg path not set

of course you can not find any info regarding ffmpeg in  encoding.xml
you need to add some strings:
see this link and find EncoderAppPath and EncoderAppPathDisplay

Thank you Serge, that got me in the right direction but not actually the problem. The problem as it turns out is
Jellyfin requires version 4 of ffmpeg. Unfortunately I followed the install instructions at https://jellyfin.org/docs/general/installation/linux/. I believe that should be updated as RMP Fusion does NOT supply version 4 which is required for Jellyfin. After going through the error logs yet again I noticed at startup it found ffmpeg but comlainged it was wrong version ( wish I had seen that first day, sorry ). Of course when Jellyfin fails to play video the screen simply said ffmpeg path not set. The log showed

I found a version 4 for CentOS 7 at https://websitehostingkenya.com/installi...-terminal/. It appears to work with Jellyfin just fine.

Many thanks to all that replied and put up with this old man.
