IDXVAHD_VideoProcessor::SetVideoProcessStreamState method (dxvahd.h)
Sets a state parameter for an input stream on a Microsoft DirectX Video Acceleration High Definition (DXVA-HD) device.
Syntax
HRESULT SetVideoProcessStreamState(
[in] UINT StreamNumber,
[in] DXVAHD_STREAM_STATE State,
[in] UINT DataSize,
[in] const void *pData
);
Parameters
[in] StreamNumber
The zero-based index of the input stream. To get the maximum number of streams, call IDXVAHD_Device::GetVideoProcessorDeviceCaps and check the MaxStreamStates member of the DXVAHD_VPDEVCAPS structure.
[in] State
The state parameter to set, specified as a member of the DXVAHD_STREAM_STATE enumeration.
[in] DataSize
The size, in bytes, of the buffer pointed to by pData.
[in] pData
A pointer to a buffer that contains the state data. The meaning of the data depends on the State parameter. Each state has a corresponding data structure; for more information, see DXVAHD_STREAM_STATE. The caller allocates the buffer and fills in the parameter data before calling this method.
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
Call this method to set state parameters that apply to individual input streams.
