In POSIX operating systems there's a SIGSTOP and SIGCONT, I've belive that's 
what you've used with kill(). I've used some windows video converters which 
use ffmpeg.dll and at least one of those had a pause button if I remember 
well, maybe there's a cross platform way. Have you asked in ffmpeg user 
mailing list?
If you find something related to ffmpeg or a more general cross-platform 
approach I'd be glad to know.
