change webcam settings for v4l linux webcams

[Gelonida N]

Hi,

I'd like to write some code to capture images from a web cam.

I found opencv and videocapture.


However it seems, that the python opencv API is quite limited.
I don't seem to be able to set all parameters (focus,contrast,exposure,. 
. . )  of a web cam via opencv.


Is there any python module, that would allow me to query / configure 
such settings?
