IMFVideoProcessorControl::SetRotation method (mfidl.h)

  • Article

Specifies whether to rotate the video to the correct orientation.

Syntax

HRESULT SetRotation(
  MF_VIDEO_PROCESSOR_ROTATION eRotation
);

Parameters

eRotation

A MF_VIDEO_PROCESSOR_ROTATION value that specifies whether to rotate the image.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The original orientation of the video is specified by the MF_MT_VIDEO_ROTATION attribute of the input media type.

If eRotation is ROTATION_NONE, the video processor does not correct the orientation of the output video. If the original video is rotated, and eRotation is ROTATION_NORMAL, the video processor corrects the orientation, so that the output video is not rotated. The video processor letterboxes the output as needed.
