I have build a video recording app based on https://developer.apple.com/documentation/avfoundation/capture_setup/avcam_building_a_camera_app
I have exteded the sample to use stabilization, but I am not near getting as good results as I get from using the Apple Photo App.
The only thing I seem to be able to control from AVFoundation is https://developer.apple.com/documentation/avfoundation/avcaptureconnection/1620484-preferredvideostabilizationmode
Do Apple use different APIs than what is available from AVFoundation?
