I agree that it should be done in user space. But as long as 99% of the
application would have to be rewritten since they all expect some rgb and
cannot handle anything else I don't even think about removing it. If someone
would write a nice library for the suitable image conversions that applications
start to use things look different. But until that I think we should provide
the conversions in kernel space. Actually IMHO this is something teh v4l2
people should think about. They should provide such a library as part of a
minimal v4l API. Otherwise driver writers are always forced to some kludge. At
least if they would like people to use their driver. ;)
