Concatenates 4 chars to a fourcc code
.. ocv:function:: static int VideoWriter::fourcc(char c1, char c2, char c3, char c4)
.. ocv:pyfunction:: cv2.VideoWriter_fourcc(c1, c2, c3, c4) -> retval
This static method constructs the fourcc code of the codec to be used in the constructor :ocv:func:`VideoWriter::VideoWriter` or :ocv:func:`VideoWriter::open`.
