Displaying a webcam feed using OpenCV and Python

Question

I have been trying to create a simple program with Python which uses OpenCV to get a video feed from my webcam and display it on the screen.

I know I am partly there

Answer 1

Try the following. It is simple, but I haven't figured out a graceful way to exit yet.

import cv2.cv as cv
import time

cv.NamedWindow("camera", 0)

capture = cv.CaptureFromCAM(0)

while True:
    img = cv.QueryFrame(capture)
    cv.ShowImage("camera", img)
    if cv.WaitKey(10) == 27:
        break
cv.DestroyAllWindows()
