Remarks

If you provide a software plug-in for DXVA-HD, the plug-in must implement a set of functions that are defined by the function pointer types in this structure.

At initialization, the DXVA-HD runtime calls the plug-in device's PDXVAHDSW_Plugin function. This function fills in a DXVAHDSW_CALLBACKS structure with pointers to the set of functions that are implemented by the plug-in device. When the application calls DXVA-HD methods, the DXVA-HD runtime calls the corresponding plug-in functions.
