Sorry for the spam. I didn't realize that Carl has answered my question already. As the default demuxer failed to work, it's necessary to specify -fps in the command line. This will overwrite the wrong fps (15) mplayer got from the media file, and make sure video and audio are in sync. Anyway, if there is any change can be made in mplayer to make it smarter as other players do, that will be really appreciated!
