I am using a named pipe to control mplayer and can't get it to play back above 4x. The man page says up to 100x should work, but when I try to set playback speed above 4x, Mplayer just sets it at 4x. I was wondering if this might be a limitation of the video codec or the remote control protocol. I can re-encode the video in any format necessary. I also don't mind modifying source code if I need to. What can I do to get MPlayer to play back at 8x, 16x, 32x, etc.?
