How to get raw camera data with C/C++?

Question

I would like to understand how to get raw camera data (RGB pixel values) without any frameworks like OpenCV, Qt Multimedia or the AV Foundation using C/C++. I can't find any good resource on this topic.

I understand that most of the cameras/webcams have differences, so for simplicities sake what I would like to do is to access the raw input from the iSight camera in my Macbook Pro. (but any kind of camera input is good, USB too)

I assume that there is a port that I can connect to, however I don't really know where to start.

Answer 1

Try an embedded video board like TI's EVMDM6437.

You cannot go "RAW" without DMAing YUV422 steam directly into CPU's L1!
