The issue is that the scaling setup depends on the number of visible rows/cols of the input image. With mt9v011 (Silvercrest), the resolution is 640x480. So, the scaling is different from a normal TV image (720x480 on NTSC). This were causing a wrong scaling and a previous patch disabled scaling. As each sensor have their different resolution setting, the xres/yres should be adjusted accordingly with the input sensor. Signed-off-by: Mauro Carvalho Chehab
