title: Windows Mobile / Directdraw: Rotate video stream

  <p>I managed to preview the camera's video stream, but the image is rotated by 90° to landscape mode. I'm now searching for a way to rotate the camera image back to normal, but the problem is I don't even know where to start: Is this done in the VideoCaptureFilter, the VideoInfoHeader, in a DDSURFACEDESC structure? Can the rotation only be done by using an additional filter? Is it a filter setting?</p>
