Answer 1

In BroadcastExtension you can use sampleBuffer to understand orientation:

if let orientationAttachment =  CMGetAttachment(sampleBuffer, RPVideoSampleOrientationKey as CFString, nil) as? NSNumber 
{  
          let orientation = CGImagePropertyOrientation(rawValue: orientationAttachment.uint32Value)   
}
