PyGame is an exceptional framework, and it's actually amazing easy to grab frames from your webcam using it! :)

 5 pygame.camera.init()
 6 
 7 cameras = pygame.camera.list_cameras()
 8 
 9 print "Using camera %s ..." % cameras[0]
10 
11 webcam = pygame.camera.Camera(cameras[0])
12 
13 webcam.start()
14 
15 # grab first frame
16 img = webcam.get_image()
17 
18 WIDTH = img.get_width()
19 HEIGHT = img.get_height()
20 
21 screen = pygame.display.set_mode( ( WIDTH, HEIGHT ) )
22 pygame.display.set_caption("pyGame Camera View")
23 
24 while True :
25     for e in pygame.event.get() :
26         if e.type == pygame.QUIT :
27             sys.exit()
28     
29     # draw frame
30     screen.blit(img, (0,0))
31     pygame.display.flip()
32     # grab next frame    
33     img = webcam.get_image()
