I was pondering converting THE CYBERIZER to a macOS app so that it would be usable by non-combatants who cannot command-line. It is a long but straightforward perl script that invokes command-line ffmpeg to analyze and generate video files. Wrapping an ObjC GUI around it is the easy part; the hard part is dropping a known-good copy of both perl and ffmpeg, along with associated libraries, into the app bundle so that it won't require the end user installing MacPorts first or whatever.

Is this a thing that anyone has accomplished?

Rewriting all of that perl code in ObjC that uses the ffmpeg library API instead of the command-line version -- though perhaps more sane -- would be enough work to turn this idea into: "Nah, nevermind."

Previously, previously.
