DXVAHDDDI_STREAM_STATE_PRIVATE_DATA structure (d3dumddi.h)
The DXVAHDDDI_STREAM_STATE_PRIVATE_DATA structure describes stream-state data that specifies a private stream state.
Syntax
typedef struct _DXVAHDDDI_STREAM_STATE_PRIVATE_DATA {
[in] GUID Guid;
[in] UINT DataSize;
[in/out] VOID *pData;
} DXVAHDDDI_STREAM_STATE_PRIVATE_DATA;
Members
[in] Guid
A GUID that identifies the private stream state.
[in] DataSize
The size, in bytes, of the private stream-state data.
[in/out] pData
A pointer to the private stream-state data. The caller sets pData to NULL to retrieve the size of the private stream-state data.
Remarks
Unlike other stream states (DXVAHDDDI_STREAM_STATE), the Direct3D runtime does not maintain the private stream state. An application and the driver communicates the private stream state directly through a proprietary manner, which consists of setting and retrieving the private stream state.
To set private stream state, the application causes the Direct3D runtime to specify the DXVAHDDDI_STREAM_STATE_PRIVATE state in the State member of the D3DDDIARG_DXVAHD_SETVIDEOPROCESSSTREAMSTATE structure in a call to the driver's SetVideoProcessStreamState function. To retrieve private stream state, the application causes the Direct3D runtime to call the driver's GetVideoProcessStreamStatePrivate function.
