How to open camera with pygame in Windows?

Question

I want to open the camera with Python using the pygame module on a Windows 7 machine, but it’s not working. I have previously used "/dev/video0" which is the read device in Linux. The pygame documentation just shows how to open a camera device in Linux. I am using pygame version 1.9.1 and Python 2.7.

How can I open the camera on a Windows device? When I try my existing script, the error I get is:

File "E:/test_python/open_cam2.py", line 10, in <module>
    cam = pygame.camera.Camera("/dev/video0", (640, 480))
File "C:Python27libsite-packagespygame_camera_vidcapture.py", line 47, in init
    self.dev = vidcap.new_Dev(device, show_video_window)
TypeError: an integer is required

Try this,

 import pygame.camera
 import pygame.image
 import sys

 pygame.camera.init()

 cameras = pygame.camera.list_cameras()

 print "Using camera %s ..." % cameras[0]

 webcam = pygame.camera.Camera(cameras[0])

 webcam.start()

 # grab first frame
 img = webcam.get_image()

 WIDTH = img.get_width()
 HEIGHT = img.get_height()

 screen = pygame.display.set_mode( ( WIDTH, HEIGHT ) )
 pygame.display.set_caption("pyGame Camera View")

 while True :
     for e in pygame.event.get() :
         if e.type == pygame.QUIT :
             sys.exit()

     # draw frame
     screen.blit(img, (0,0))
     pygame.display.flip()
     # grab next frame    
     img = webcam.get_image()

This should work…

import pygame
import pygame.camera

pygame.init()

gameDisplay = pygame.display.set_mode((1280,720), pygame.RESIZABLE)

pygame.camera.init()
cam = pygame.camera.Camera(0,(1280,720))
cam.start()
while True:
    img = cam.get_image()
    gameDisplay.blit(img,(0,0))
    pygame.display.update()
    for event in pygame.event.get() :
        if event.type == pygame.QUIT :
            cam.stop()
            pygame.quit()
            exit()

I’m using windows 10 , pygame version 1.9.6

The pygame.camera module natively supports cameras under Windows since version 2.0.2. See a minimal example using the pygame.camera module (tested with Windows):

import pygame
import pygame.camera

pygame.init()
pygame.camera.init()

camera_list = pygame.camera.list_cameras()
camera = pygame.camera.Camera(camera_list[0])

window = pygame.display.set_mode(camera.get_size())
clock = pygame.time.Clock()
camera.start()

run = True
while run:
    clock.tick(100)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    camera_frame = camera.get_image()

    window.fill(0)
    window.blit(camera_frame, (0, 0))
    pygame.display.flip()

pygame.quit()
exit()
