* format is now entered as a parameter string (-g <mode>) * expect currently buffers as big as needed (exactly one frame) TODO: revide if isn't possible to read whole buffer at once (ideally the memmapped one, and extract frames by hand) * now it is needed to set /sys/class/sdivideo/sdivideorxX/bufsize * bump to new driver (2.7.2)
