pygame.camera hangs on get_image()

Former Member
Former Member over 12 years ago

Hi,

Ive got a problem with my pi freezing. it becomes unresponsive as soon as I call get_image() in my python script

 

Its a simple script...

 

[code]

import pygame

import pygame.camera

import pygame.image

import os

 

from pygame.camera import *

from pygame.locals import *

 

 

print "starting capture"

pygame.init()

 

pygame.camera.init()

 

size = (50,50)

cam = pygame.camera.Camera('/dev/video0', size, 'RGB')

print("cam created")

  

cam.start()

print("cam started")

 

 

img = cam.get_image()

print("gettting image")

[/code]

 

My script gets as far as "cam started"

 

I have succesfully taken a photo using the fswebcam program. No problem. It just wont take a photo via my python script.

 

I have uninstalled python along with pygame and resintalled and still have the same issue.

 

Any ideas?

 

 

Thanks

Aidan

    Is this with the RPi CSI addon camera, or some other usb camera ?

     

    According to jamesh over on the rpi forums there's currently no v4l driver for the csi board, so /dev/video0 won't work for that camera.

     

    Apologies if I'm off track, but you don't say what camera you're using and as the camera addon has just been released....

    Yeah sorry,

    Its just a Philips usb web cam. The Pi seems to pick it up fine on start up and as with other cams Ive tried.

     

    Its so annoying! first little project ive set out to do and im falling at the first jump!
