That's probably why mplayer devs recommend using mkfifo (named pipe) instead of stdout.. 'mencoder' can do it. If you need to support a variety of unknown formats and codecs: ffmpeg is an alternative and gstreamer might be one. ffmpeg -i /some/file -f u16le -acodec pcm_s16le -ar 44100 - \ | jack-stdin system:playback_1 system:playback_2 on that note, `jack-stdout` can capture and pipe raw PCM data from any JACK-application including `mplayer -ao jack /some/file`. YMMV. HTH, robin _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
