What is the difference between the CvCapture structure and the VideoCapture structure?

Question

Is there any difference between the CvCapture structure and the VideoCapture structure in OpenCV? If so, when should I use CvCapture and when to use VideoCapture?

Answer 1

VideoCapture is from the new C++ interface, CvCapture no longer has a public interface for use.

When using the C++ API, VideoCapture should be used. You should avoid mixing the two interfaces.

If you are using the C API, rather than the C++ API, several methods return a CvCapture pointer, such as cvCaptureFromFile.
