I am using is in /usr/bin my PATH variable value is  :
/home/jim/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin
so includes /usr/bin .

"apt-list ffmpeg" shows the version 7 package is installed
/jammy-apps-security,now 7:4.4.2-0ubuntu0.22.04.1+esm5 amd64 [installed]

I'm still thinking that "ffmpeg -version"  which shows :
ffmpeg version 4.4.2-0ubuntu0.22.04.1+esm5 Copyright (c) 2000-2021 the
FFmpeg developers
is dropping the 7 . It seems like quite a coincidence that the version
shown ie. 4.4.2 is the last 3 numbers of version 7 package?
