[sugar] Could not initialize video capture device (VIDIOCGMBUF)

[Peter Krenesky]

Hi all,

I'm working to port helix producerSDK (video/audio capture, editing, encoding) 
to python so it can be used in an activity.  I've gotten enough of the api 
ported to capture video/audio on my desktop.   

Audio capture works on the XO but video does not.  I get an error about 
VIDIOCGMBUF:


        Diagnostic      None    2007/08/16 16:48:38     0       Ignoring

any ideas?
