ID3D11VideoContext::VideoProcessorSetOutputBackgroundColor

DX11 vtable[14] → void

ID3D11VideoContext::VideoProcessorSetOutputBackgroundColor is a method of the COM interface ID3D11VideoContext in Direct3D 11. Its function pointer sits at vtable index 14 — the zero-based slot in that interface's virtual method table, counted from QueryInterface and including every entry inherited from a base interface. It takes 3 parameters (processor, y_cb_cr, color) and returns void.

COM methods are reached through that table rather than by an exported name, so the slot index is what a wrapper, an interface hook or a disassembly listing has to resolve against. The parameter order and types below are the ones this interface declares.
