OpenGL Image processing

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?

Check out Nvidia's developer site and find GPU Gems 1 (all 3 books are available online). It has a chapter about image processing on the GPU and how to do it.

Here's the link: http://http.developer.nvidia.com/GPUGems/gpugems_ch27.html
