Open video file or a capturing device for video capturing
C++: bool VideoCapture::open(const string& filename)
C++: bool VideoCapture::open(int device)
从open()函数的申明可以看出，这个函数有重载的哦。。。追问但int device是制定device吧，
capture.open(0)不就应该是第二个吗追答filename – name of the opened video file (eg. video.avi) or image sequence (eg.
img_%02d.jpg, which will read samples like img_00.jpg, img_01.jpg, img_02.jpg, ...)
device – id of the opened video capturing device (i.e. a camera index).
