        self.cap.set(3, 640)
        self.cap.set(4, 480)

640 = width
480 = height

If you want them to be environment variables, do something like

import os
...
CAP_WIDTH = os.environ.get("CAP_WIDTH", 640)
CAP_HEIGHT = os.environ.get("CAP_HEIGHT", 480)
...
        self.cap.set(3, CAP_HEIGHT)
        self.cap.set(4, CAP_WIDTH)
