- UVC Camera Preparation

http://linuxtv.org/wiki/index.php/Webcam_Devices teaches us, that there are four types of web cams:

those that have UVC support →Linux UVC driver and tools

those that have GSPCA support →http://linuxtv.org/wiki/index.php/Gspca

those that have out-of-tree support

those that have no Linux support

Then there is the framework Video4Linux and a whole load of applications that work with V4L version 1 and/or version 2.
