ID3D11VideoContext::VideoProcessorSetStreamRotation method
Sets the stream rotation for an input stream on the video processor.
Syntax
void VideoProcessorSetStreamRotation(
ID3D11VideoProcessor *pVideoProcessor,
UINT StreamIndex,
BOOL Enable,
D3D11_VIDEO_PROCESSOR_ROTATION Rotation
);
Parameters
- pVideoProcessor
-
A pointer to the ID3D11VideoProcessor interface. To get this pointer, call ID3D11VideoDevice::CreateVideoProcessor.
- StreamIndex
-
The zero-based index of the input stream. To get the maximum number of streams, call ID3D11VideoProcessorEnumerator::GetVideoProcessorCaps and check the MaxStreamStates structure member.
- Enable
-
Specifies if the stream is to be rotated in a clockwise orientation.
- Rotation
-
Specifies the rotation of the stream.
Return value
This method does not return a value.
Remarks
This is an optional state and the application should only use it if D3D11_VIDEO_PROCESSOR_FEATURE_CAPS_ROTATION is reported in D3D11_VIDEO_PROCESSOR_CAPS.FeatureCaps.
The stream source rectangle will be specified in the pre-rotation coordinates (typically landscape) and the stream destination rectangle will be specified in the post-rotation coordinates (typically portrait). The application must update the stream destination rectangle correctly when using a rotation value other than 0° and 180°.
