It might not be exactly what you want, but I utilize the command line
ffmpeg program in windows in my tivo server program.
https://github.com/wcbonner/WimTiVoServer/blob/master/WimTiVoServer.cpp
around line 1200. I pipe the output of STDOUT from the ffmpeg and read it's
contents in my C program, then proceed to loop reading the output and
writing it into an http chunked stream. The command I use to run FFMPEG has
it writing it's output to STDOUT and my C program takes care of redirecting
STDOUT before creating the FFMPEG chile process.
Wim.
