How can you zoom the video under c++? What does zoom means? Something like resize? Or what player does the zoom you want?

I am not familiar with opencv in java, but generally you should be able to take a rectangle out of your image according to the zoom level you want it to be (this I assume will be a Mat) and then resize it to fit your window/original frame, and then insert it back into the window. A zoom in Videos normally is nothing other than up scaling
