i am trying to use mplayer to add ssa subtitles to my videos using this FAQ link
mplayer -vf expand=:-60::2 -ao pcm foo.avi -ass -sub subtitles.ssa -vo yuv4mpeg
the above creates a .wav audio file called "audiodump.wav" and a "stream.yuv" file. I just want the audio to be included in the stream.yuv, is that possible? I tried removing -ao pcm but stream.yuv still no sound/audio.
