MPEG: likely. MPEG LA owns patents on the compression modes. divx is the
same story, since it's essentially MPEG LA's MPEG-4 with some custom
divx specialities. You might have to pay to divx.com, too, I'm not very
familiar with how divx.com handles this.
mp3 is patented and owned by Fraunhofer, and they require license fees,
too.
Note that all that goes only if you want to distribute your commercial
application publically. If you plan on using it internally, they won't
go after you that quickly, afaik, even though its use officially still
requires such fees.

Since we're GPL, no (as in: you cannot copy our code into your
application). You can call mjpegtools applications via unix pipes for
data interchange (stdin/stdout, frames, etc.). That's allowed by the
GPL.

That's allowed, just like unix pipes, since there's no binary linking
going on and they run as separate programs (independently).
