I have just tested this simple project on a Ubuntu Mint 21 VM without 
'ffmpeg' installed:

Public Sub Main()

  Exec ["ffmpeg"] Wait
  Shell "ffmpeg" Wait

End Sub

I created an AppImage from it, adding 'ffmpeg' as extra-dependencies.

Then I run the resulting AppImage on the same system.

- 'Exec' runs the embedded ffmpeg as expected.
- 'Shell' fails to run the embedded ffmpeg, it does not find it.
