Hi all,

I'm working to port the producerSDK to python for use by the
one laptop per 
child (OLPC).  I've gotten enough of the api ported to
capture video/audio on 
my desktop.  

Audio capture works on the OLPC but video does not.  I get
the following log 
messages while trying to create an input for video capture:
