    Hi Jernej,
    
    I found something odd in the compliance output:

    This claims that the driver supports scaling, but I don't think that is right.
    
    More likely the deinterlacing part is what confuses the compliance test.
    
    Can you look in v4l2-test-formats.cpp, function testBasicScaling() where it
    sets node->can_scale to true? And see if this is due to a driver bug, or due
    to a bug in the test?
    
    Regards,
    
    	Hans
