ok. i thought about it and a new idea came to my mind:
-> you can look at it like this: a system that can replace a few
frames/gops inside a big (1gb) mpeg4/h264 videofile. because this
should happen very fast it would be cool if just the parts/frames/gops
that have to be updated can be replaced/changed without having to
write the whole file down to a new file. writing down 1 gb takes us
more than a minute on our system. this is too long to wait for this
download, isn't it?
would be really cool if you could help us to make such a system. we
will find a way to reward you for the work if the solution really
