This is saying it can't access ffmpeg.  Which means when Jellyfin is calling "ffmpeg" it is getting the other ffmpeg you have on your system and Jellyfin doesn't have access to it.

I'm not entirely sure how to change this in newer versions of Jellyfin since we locked down changing the ffmpeg path due to security issues.

I think you'd have to modify C:\ProgramData\Jellyfin\Server\config\encoding.xml and provide the full path to ffmpeg.exe in the Jellyfin Program Files folder.
