User is having an error trying to run Ffmpeg

[blackears]

I've written a script that uses the whisper Python library. I've had one user on a mac run into some sort of situation where whisper fails to run ffmpeg on the command line. I have no idea why this might be happening. I've had them check that ffmpeg is installed on the path and has the correct permissions. Any idea how I can fix this?
