I have written some code that provides me with the raw data of video frames and I want to manipulate the pixel data of each frame. I am using OpenGL (in Qt) and C++. After manipulating the video frame I want to render it using OpenGL. I have researched that I probably should use FBOs to render the data, but I don't quite know how it all works. Do I have to copy the video frame into a texture and then use that texture in combination with the FBO? How would I set that up? I have found some tutorials about how to use FBOs in 3D, but they don't really explain the mechanics about it. I only need to set up a 2D environment to display the video frames, don't I. Can anyone point me to some tutorials that actually explain things in detail and use plain OpenGL?

I believe it was in GPU Gems 1 (might be 2) that had a framework for image processing on the GPU. They're both freely available on http://developer.nvidia.com

Found it: http://http.developer.nvidia.com/GPUGems/gpugems_ch27.html

Cheers,

Bob
