View the official Windows Driver Kit DDI referenceNo description available.
The DXVAHDDDI_STREAM_STATE_PRIVATE_DATA structure describes stream-state data that specifies a private stream state.
Guid [in]A GUID that identifies the private stream state.
DataSize [in]The size, in bytes, of the private stream-state data.
pData [in/out]A pointer to the private stream-state data. The caller sets pData to NULL to retrieve the size of the private stream-state data.
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.
