I have and avi file and an ac3 file that contains an alternate audio stream. I run mplayer like:

mplayer -audiofile foo.ac3 bar.avi

mplayer takes the audio stream from the ac3 file as expected, but when I try to scroll the video using arrows or pgup/pgdown keys, the audio gets desynced: mplayer just starts playing the audio stream from the beginning.

Do I have to pass any additional command line arguments in order to make it scroll properly without desyncing audio?

My mplayer scrolls both video and external audiofile. – Vi. Mar 18 '10 at 18:56
@Vi: what version are you using? Maybe I have an outdated one. – geek Mar 18 '10 at 19:25
MPlayer UNKNOWN-4.3.2 (C) 2000-2009 MPlayer Team (built from SVN) MPlayer SVN-r29142-4.3.3 (C) 2000-2009 MPlayer Team (Debian squeeze's, but not up to date). Both are scrolling both audiofile and video. – Vi. Mar 18 '10 at 20:02
Mine is more recent (r29390) and I get audio desynced. – geek Mar 18 '10 at 20:05
May be it is because I'm testing not with that ac3 format but with plain wav or mp3? Try to generate simpler sound sox -n qqq.wav synth 440 and test with it. – Vi. Mar 18 '10 at 20:13

Try to process your video through the mencoder which also supports -audiofile option. I hope the resulting file will be scrollable.

My goal is to be able to watch the video with an alternate audio stream without doing any processing. – geek Mar 18 '10 at 19:26
