Hi,
I am pretty new to DirectX and I need to accomplish the following thing:
Preview a live video stream from a webcam and be able to select (draggable&resizable rectangle) an area of the live video and apply some real-time image processing only on that area.
This involves video overlay (for the selection rectangle) and video processing of a portion of the video stream.
I understand I can use DirectShow for the capture part and then DirectDraw for the image processing and rendering...
But that's very general. Can anyone give me some details on how to actually do that? What is the best way to do it? :-)
Thanks!
