I'd like to grab a frame from my MacBook Pro iSight in C++ and do some elaborations on it. I already know how to do that in ObjC with QTKit, but is there any way to do the same thing in C++?
NOTE: I tried to install OpenCV with macports, but the framework doesn't seem to support iSight cameras.
You could do that using OpenCV ( http://opencv.willowgarage.com/wiki/ )
And here is a sample code you can copy/paste to try it : http://www.geckogeek.fr/lire-le-flux-dune-webcam-camera-video-avec-opencv.html (article in french but code is in english)
