Hello!
Okay, I understand. What I really want is some way to play compressed video. I have a lot of frames (about 5000) and pictures of size 200x200 or more. Uncompressed, this is way too much to have in memory (2.8 G). The other is to load it frame by frame, but this means I have to have 5000 png's or jpg's, which isn't good either. So I was looking at mng as a quick and easy way to do this, since it's almost like png, so I figured it would be pretty easy to add support for it.
I've already animated it 'by hand', and it does look nice, but it's way too big to do without compression.
