ID3D11VideoContext::VideoProcessorGetStreamPixelAspectRatio

DX11 vtable[47] → void

ID3D11VideoContext::VideoProcessorGetStreamPixelAspectRatio is a method of the COM interface ID3D11VideoContext in Direct3D 11. Its function pointer sits at vtable index 47 — 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 5 parameters (processor, stream_idx, enabled, src_aspect_ratio, dst_aspect_ratio) 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.
