Well, the video itself _could_ be MPEG-4, the container certainly isn't,
but it is simple enough that someone skilled should not take much more
than a few hours to reverse-engineer and the same time to implement it.
I just have some doubts someone wants to waste his time on this.
If you can prove they use MPlayer of FFmpeg you can of course ask them
for the source, and if they did not give it to you or a written offer of
it they already belong here: http://ffmpeg.org/shame.html
