I run ffmpeg from my c++ program using the traditional fork/exec process.
It allows me to use the standard ffmpeg without having to maintain all of
the libraries to build it.

Years ago I started developing with the libav libraries and realized that
for small projects it was going to be a much larger learning and
maintenance curve than I wanted to travel.

I've used ffmpeg from c++ in linux as in the previous example, and in
windows I've used createprocess with ffmpeg output going to a pipe that I'm
reading in my C++ code and sending over tcp.
