DXVA_ConnectMode structure (dxva.h)

  • Article

The DXVA_ConnectMode structure is sent by the host decoder to the accelerator to define the restricted profile used within a DirectX VA connection.

Syntax

typedef struct _DXVA_ConnectMode {
  GUID guidMode;
  WORD wRestrictedMode;
} DXVA_ConnectMode, *LPDXVA_ConnectMode;

Members

guidMode

Specifies the GUID associated with the restricted profile to be used.

wRestrictedMode

Specifies the numeric identifier of the restricted profile to be used.

Remarks

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.
