Cant save image using OpenCV

Question

I was trying to save images from a video file but It couldn\'t save any image in my hard drive. I compiled following program without errors.

#include 

        

Answer 1

You forgot to actually save the image:

cvSaveImage(buffer ,img);

Also, the following is redundant:

IplImage* small; // <-- you don't need this
IplImage* small=new IplImage(inputArray);
