Hello I like to publish a new git repository http://git.code.sf.net/p/v4lstack/code git clone http://git.code.sf.net/p/v4lstack/code v4lstack 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. Greetings Markus -- Dipl.-Ing. Markus Bader PS.: A lot of things would be easier by adapting the dynamic reconfigure package 1.) it would be nice to access all variables with a std::map 2.) the node should be able to trigger a reload on the reconfigure gui or way not enhancing the shared parameters with an info text and limits, this a interface could be generated without writing any configuration file :-)
