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.
