The problem is that since mplayer reads the -audiofile at an irregular
rate, it is possible for it to reach the end of the audio-file, in which
case it detects it as eof, and the rest of the encoding is done with no
audio (in fact, this isn't just possible, it happens to me every time)
So I'm still out of ideas. I think it is particularly painful when using
raw video, because of the huge discrepency in size between the video and
audio frames. Thus it is hard to cache enough video to get a decent
audio buffer. Oh well.
