The DXVA_ConnectMode structure is sent by the host decoder to the accelerator to define the restricted profile used within a DirectX VA connection.
guidModeSpecifies the GUID associated with the restricted profile to be used.
wRestrictedModeSpecifies the numeric identifier of the restricted profile to be used.
The following GUIDs placed in the guidMode member of this structure set the restricted profile to be used. The constants that define the GUIDs used are in dxva.h.
