     This property is only applicable to AVCaptureConnection instances involving video or depth. -setVideoRotationAngle: throws an NSInvalidArgumentException if set to an unsupported value (see -isVideoRotationAngleSupported:). Note that setting videoRotationAngle does not necessarily result in physical rotation of video buffers. For instance, a video connection to an AVCaptureMovieFileOutput handles orientation using a Quicktime track matrix. In the AVCapturePhotoOutput, orientation is handled using Exif tags. And the AVCaptureVideoPreviewLayer applies transforms to its contents to perform rotations. However, the AVCaptureVideoDataOutput and AVCaptureDepthDataOutput do output physically rotated video buffers. Setting a video rotation angle for an output that does physically rotate buffers requires a lengthy configuration of the capture render pipeline and should be done before calling -[AVCaptureSession startRunning].
 
     Starting with the Spring 2024 iPad line, the default value of videoRotationAngle is 180 degrees for video data on Front Camera as compared to 0 degrees on previous devices. So clients using AVCaptureVideoDataOutput and AVCaptureDepthDataOutput should set videoRotationAngle to 0 to avoid the physical buffer rotation described above. And clients rotating video data by themselves must account for the default value of videoRotationAngle when applying angles (videoRotationAngleForHorizonLevelPreview, videoRotationAngleForHorizonLevelCapture) from AVCaptureDeviceRotationCoordinator. Note that this change in default value is currently limited to these iPads, however it is recommended that clients rotating video data themselves incorporate the default rotation value into their workflows for all devices.

+    Clients using AVCaptureVideoDataOutput with ProRes Raw should set videoRotationAngle to 0 as rotation is not supported for RAW buffers. If clients want to rotate these buffers themselves they need to apply rotation angles (videoRotationAngleForHorizonLevelPreview, videoRotationAngleForHorizonLevelCapture) provided by AVCaptureDeviceRotationCoordinator.
