Class name not found when inheriting

I'm having a problem inheriting from a class, and looking up the error on the internet is said as being circular includes, but I'm not seeing how I'm doing it on my code.

Here is the error:

./src/Camera.hpp:6:40: error: expected class-name before ‘{’ token
 class Camera : public cv::VideoCapture {

The class I'm inheriting from is part of OpenCV. Here is the relevant part of the code:

main.cpp:

#include <opencv2/core.hpp>
#include "Camera.hpp"

int main(int argc, char** argv){

    Camera camera = Camera(/*Some parameters*/);
    return 0;
}

Camera.hpp

#ifndef CAMERA_H
#define CAMERA_H

#include <opencv2/core.hpp>

class Camera : public cv::VideoCapture {
    public:
    Camera(/*Some parameters*/);
};
#endif

There are some other files included in main.cpp, but I made sure (to test) that none of them is using Camera.hpp. What am I doing wrong?

Thanks

If it doesn't know VideoCapture is a class, maybe you haven't included the right header file.

http://docs.opencv.org/java/2.4.8/org/opencv/highgui/VideoCapture.html suggests #include "opencv2/opencv.hpp".
