I am trying to use mplayer to pipe audio from a video through a script that plays the audio on a special device. The problem though is that mplayer seems to internally turn off audio-video sync when i use -ao pcm:file=<file> (which is the only way I've found of making mplayer output the audio to something other than the audio out device, I'm on mac os x btw). Is there some other way out outputting the audio or some way of forcing mplayer back into audio-video sync instead of trying to decode the video as fast as possible.
