I kind of remember that I had several applications running an FFMPEG command-line app submitted to Mac App Store some 14 years ago. In the meantime, you are not specific about your development platform, making ambiguous statements like "MacOs" and "AppStore." So which is it? Is it an iOS app or macOS application?
Anyway, if you are not sure if your macOS submission does not abide by Mac App Store review guidelines, you can have your users download the command-line tool and install it on their own. I would search for 'DVD rip' at Mac App Store.
