Hey, cool. I think I actually almost came close to what you said a
couple times, lol. You just write a little more succinctly than I do,
just like Brian. :D

I think I heard that about ffmpeg by itself, but that didn't "stick"
until this time. I thought it was just more "reference", more of a
library sitting in waiting to be drawn from in the background.
