Hello Nicola, Giulhem Tardy wrote the first V4L2 patch a few years ago, I have ported it to the recent V4L2 API and to the plugins system of pwlib. The code is in the PWLIB CVS on openh323.sourceforge.net. If you compile CVS for PWLIB, OpenH323 and GnomeMeeting, then you will be able to work on it. I don't think there is much to do. Luca added Bayer->RGB conversion, and some code for Bayer->YUV conversion can be found in xawtv's code. From there, you can start debugging the existing code. I don't think there is much to do, really, but I lack the time, and the hardware to do it.
