How to capture Video with OpenCV

[bibhukalyana]

Why are you want to use OpenCV (for capturing image or video)?
If you want to capture image

CvCapture *capture = 0;
    IplImage  *frame = 0;
    capture = cvCaptureFromCAM( 0 );
    frame = cvQueryFrame( capture );

CvCapture *capture = 0;
    IplImage  *frame = 0;
    capture = cvCaptureFromCAM( 0 );
    frame = cvQueryFrame( capture );

To copy to clipboard, switch view to plain text mode 

In frame you get all the data of image.

Hi,

Make sure your webcam is connected and working.

I made it work using

CvCapture * camera = cvCreateCameraCapture(0);

CvCapture * camera = cvCreateCameraCapture(0);

To copy to clipboard, switch view to plain text mode 

If argument 0 does not work, try with 1, and so on.
