Video Player

[shawshank]

I am making a simple GUI for a video player. But I would like to take input from webcam or a external camera.
Can someone please guide me on how to do it?

Have you already checked out OpenCV?

EDIT: I've just read that "the Qt Multimedia API provides a number of camera related classes".
