I like to publish a new git repository http://git.code.sf.net/p/
git clone http://git.code.sf.net/p/
The repo holds a v4l camera driver (based on the luvcview program)
with a dynamic reconfigure interface.
Including reading and storing parameters, like brightness, contrast,
... and even focus if the camera supports it.
A tiny program generates the dynamic reconfigure configuration file
CameraParameters.cfg by testing all supported controls.
But still a lot of things can be enhanced, therefore I am happy to
find other developers.
