If it does, then you should first find that version of ffmpeg. The one
you are executing is clearly 4.1.9.

$ which -a ffmpeg
assuming your `which` supports this. Alternatively:
$ echo $PATH | tr : '\n' | while read p; do if [ -f "$p/ffmpeg" ]; then ls -l "$p/ffmpeg"; fi; done

If you only get the one executable, try searching the complete file
system:
$ find / -type f -name ffmpeg

Once you have found it, either try it, or show us
$ /path/to/ffmpeg -h

Cheers,
