The D3DDDI_VIDEO_PRESENT_SOURCE_ID data type is defined in D3dukmdt.h.

Video present source identifiers are assigned by the operating system. DxgkDdiStartDevice, implemented by the display miniport driver, returns the number N of video present sources supported by the display adapter. Then the operating system assigns identifiers 0, 1, 2, ... N - 1.
