Hm, well I see that and now I am thinking of using reference software
for MPEG4/10 which is written in c++  http://iphome.hhi.de/suehring/tml/
just to use it as a decoder on my client side, save the file in that
format and then play it in my player using pyffmpeg
http://code.google.com/p/pyffmpeg/ and just manipulate frames in that
clip-I think that could be possible....am I right? Thanks for your
help!
