ID3D11VideoContext::VideoProcessorGetStreamOutputRate

DX11 vtable[42] → void

ID3D11VideoContext::VideoProcessorGetStreamOutputRate is a method of the COM interface ID3D11VideoContext in Direct3D 11. Its function pointer sits at vtable index 42 — 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, rate, repeat, custom_rate) 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.
