                //Add video data output
                self.bufferFrameQueue = DispatchQueue(label: "bufferFrame queue", qos: .userInitiated,  attributes: [.concurrent], autoreleaseFrequency: .workItem)
         
                self.videoDataOutput = AVCaptureVideoDataOutput()
                if self.session.canAddOutput(self.videoDataOutput!) {
                    self.session.addOutput(videoDataOutput!)
                    self.videoDataOutput!.alwaysDiscardsLateVideoFrames = true
                    self.videoDataOutput!.connection(with: AVMediaType.video)?.videoOrientation = .portrait
                    self.videoDataOutput!.videoSettings = [kCVPixelBufferPixelFormatTypeKey: Int(kCVPixelFormatType_32BGRA),
                                                           kCVPixelBufferHeightKey: 960,
                                                           kCVPixelBufferWidthKey: 720] as [String : Any]
                    self.videoDataOutput!.setSampleBufferDelegate(self, queue: self.bufferFrameQueue)
                }

        I am trying to specify output size to be 960x720 in video settings.  However, it doesnt seem to work.

         

        Any other way to get the vidao data output in a custom lower resolution?
