i do not expect anything from Ubuntu instructions as Redhat user

if you have no idea where the binaries installed it will be hard to help
how can anybody install self compiled things without knowing?
does the referred instruction does not state this?

if not why are you using a random instruction on the web without knowing
what happens at your system?

however, "ldd /path/to/the/ffmpeg/binary/ffmpeg" with the user
where it works will list you linked libraries like below
