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

Don't know if you solved the problem or not. if not you can use imwrite("test.jpg",img); to save an image,

here is an example- while(1) {

  img=cvQueryFrame(cv_cap);
  cvShowImage("Video",img);
  imwrite("test.jpg",img);
}

Answer 2

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);
