Load video orienting the camera to the real world horizon

[catchakos]

What should I do to have the loaded video oriented to the real world horizon?

Everything works fine and I see that by calling reorientVerticalCameraAngleToHorizon(animated:) the video is getting re-oriented to where the device is currently looking at.
But what if I want the video initial state orientation to match the real-world orientation, so as the first thing I see when I have the phone pointing to the ceiling is the sky?

Thanks in advance!
