OpenCV设置大小中的内存泄漏

Question

I am finding a memory leak in this simple OpenCV code:

VideoCapture* capture = new VideoCapture(0);
Mat frame;
while (true) {
    capture->set( CV_CAP_PROP_FRAME_WIDTH, 1600 );
    capture->set(CV_CAP_PROP_FRAME_HEIGHT, 1200 );
    capture->read(frame);
}

This is the whole code. Every time through the while loop, several MB are leaked. I have tried frame.release() just after the read, but it doesn't help. Removing the set-size lines fixes the problem, but in my real code I want to vary the size, so that isn't a solution. It is getting the image at the correct size.

Am I doing something stupid?

By the way, I am using a Logitech B910 webcam.

Thanks!

Do you need to change the readout size on every frame?

Once it is set the camera will produce the same size until you reset it
