I'm following these instructions (scroll down to "Manual Installation") to manually install get-iplayer Terminal command (don't want to use brew):
I see that this requires (and talks you through--partly) the install of ffmpeg and AtomicParsley.
I already installed ffmpeg weeks ago for another purpose so I really don't want another install of ffmpeg if I can do without it. (Can I?)
How can I proceed without installing another copy of ffmpeg?
