An ugly way that might only work with Intel HD Graphics VA drivers, i.e. a VA driver that supports VPP, is to use the output_background_color with a small 16x16 VA surface placed in the middle. An alternative is to create a black surface that you generate once but use it as source to copy to the target. You could also have the option to generate once a small VA surface and use the fast scaling option to fit your target VA surface. Not perfect, but should be faster than the other ways through vaPutImage() for instance. BTW, why would you need to do that -- I mean, filling a surface with black pixels?
