You're looking for IPC::Open3, I suspect. Certainly it's the closest analogue to the way you're doing it that I can think of. http://perldoc.perl.org/IPC/Open3.html I also note that ffmpeg is a strange beast and has a fairly undocumented remote control mechanism. At least I think that was ffmpeg. That only requires STDIN/STDOUT. James
