Using only > shell, no perl. mplayer -input file=/tmp/input-pipe >/tmp/output-pipe Or mplayer -input >/tmp/output-pipe </tmp/input-pipe Or cat /tmp/input-pipe | mplayer -input >/tmp/output-pipe The first solution is the best I think, as the pipe stays valid even if closed by a writing process as mentioned in the manpage. But in fact redirecting stdin and stdout is not really a mplayer subject, it's shell basics. Greets, Kiste
