비디오를 녹화 할 때 비디오의 변환 (초상화, 풍경 등)을 설정하는 방법은 무엇입니까?

Question

AVCaptureConnection의 VideoOrientation 속성을 사용하거나 VideoWriterInput의 변환 속성을 설정해야합니까?

Answer 1

Seems like AVCaptureConnection's videoOrientation property sets the orientation as it's recording, while the transform property of the videoWriterInput will set a flag for the playback transform.
