I think that's the problem. You can't play an MP4 before it is
finished, because it needs to add information to the file *after*
transcoding. Other formats are more suited to play while transcoding. I
think Matroska works okay, but you can't seek. (Not sure right now.)
MPEG-TS is bery well suited. (Others may be as well, but I don't have
the experience.)

If it was just an experiment to see whether ffmeg is doing okay, you'll
have to wait till the end, or interrupt with the 'q' key.

Here you see that mplayer misdetects the video format/codecs. Anything
it produces is just garbage.
