In my project I’m using AVCaptureMultiCamSession where main camera device type is .builtInWideAngleCamera and second one is .builtInUltraWideCamera. Backend team requires to send them following data: • Intrinsic Matrix of each camera (3x3 matrix). • Possibly accessible Distortion coefficients (not lensDistortionLookupTable). So my questions are: ⁃ is it possible to retrieve intrinsicMatrix for both builtInWideAngleCamera and builtInUltraWideCamera during AVCaptureMultiCamSession? ⁃ is there a way to get distortion coefficient (not lensDistortionLookupTable) for both builtInWideAngleCamera and builtInUltraWideCamera during AVCaptureMultiCamSession?

I am creating an locked camera capture extension that allows you to take a video with an overlay image on top of it. I'm using AVMutableComposition in order to achieve that. It works perfect in my main app, but when initializing AVMutableComposition in the locked camera extension it always returns nil. Is this expected?
