This document describes it's control interfaces:
http://www.videolan.org/doc/play-howto/en/ch04.html

You can control it by http, which could be nice.

Another method might be to read output from ffmpeg/vlc, and do the
display/play audio in pygame. So you'd just read frames from stdin,
and then play them back. This way might be simpler than assuming the
window of VLC.
