I am using VideoFeeder to display camera of drone, but when i use Matrice 300, the camera is not displayed.

func setVideoPreview() {

        DJIVideoPreviewer.releaseInstance()

        DJISDKManager.videoFeeder()?.primaryVideoFeed.removeAllListeners()

        DJISDKManager.videoFeeder()?.secondaryVideoFeed.removeAllListeners()

        DJIVideoPreviewer.instance().setView(self.cameraView)

             let product = DJISDKManager.product();

        //Use "SecondaryVideoFeed" if the DJI Product is A3, N3, Matrice 600, or Matrice 600 Pro, otherwise, use "primaryVideoFeed".

        if ((product?.model == DJIAircraftModelNameA3)

            || (product?.model == DJIAircraftModelNameN3)

            || (product?.model == DJIAircraftModelNameMatrice600)

            || (product?.model == DJIAircraftModelNameMatrice600Pro)) {

            DJISDKManager.videoFeeder()?.secondaryVideoFeed.add(self, with: nil)

        } else {

            DJISDKManager.videoFeeder()?.primaryVideoFeed.add(self, with: nil)

        }

   

        DJIVideoPreviewer.instance().reset()

        DJIVideoPreviewer.instance().start()

        DJIVideoPreviewer.instance().type = DJIVideoPreviewerType.autoAdapt

        DJIVideoPreviewer.instance().adjustViewSize()

}
