SimpleCV Webcam getImage() error (no attribute 'threaded')

Question

I'm trying to run a basic script to get a feed from my webcam using SimplecCV 1.3.0 with a Logitech HD C270 webcam(also tried Logitech tessar 2.0/3.7) on 64 bit Linux Mint 12.

When I trun the following script

from SimpleCV import *

cam = Camera()
while(True):
    img = cam.getImage()
    img.show()

A window pops up and I can see a camera feed. However, at seemingly random moments, the feed will freeze and throw the following error on every img = cam.getImage()

VIDIOC_DQBUF: No such device
libv4l2: error dequeuing buf: No such device

From that point on when I attempt to run the same script, the window opens for a moment, disappears, and I get the following error on the img = cam.getImage() line of my script:

File "/usr/lib/pymodules/python2.7/SimpleCV/Camera.py", line 579, in getImage
  if (not self.threaded):
AttributeError: Camera instance has no attribute 'threaded'

This error persists until I restart my computer and occurs whether my webcam is plugged in or not. Nevertheless, other webcam software(such as cheese) can still interface with the camera.

Answer 1

Did you try to something like:

cam = Camera(0)?
