The initial version of this patch (commit d5976931639176bb6777755d96b9f8d959f79e9e) had some issues: * It didn't correctly calculate the size of the YUV buffer for 4:2:2, resulting in capture sometimes being offset by 1/3rd of a picture. * There were a lot of variables duplicating information the driver already knew, which have been removed. * There was an in-kernel format conversion - libv4l can do this one, and is the right place to do format conversions anyway. * Some magic numbers weren't properly explained. Fix all these issues, leaving just the move from videobuf to videobuf2 to do.
