how to start building cooliris in openGL and C++?

Question

I have seen the post where somebody commented that cooliris can be built using C++ and openGL. I have just started learning openGL. I wanted to ask how to go about creating it?

Answer 1

First of all you must decompress your video from codec stream into frame by frame stream in your texture format. Then each frame render to texture that in framebuffer or create quad and render it with next frame as texture. While rendering you can apply shader effects for creating some funny filters. You can find some tricks here

Good luck!
