Use AudioVideoCaptureDevice to recoed video

StorageFolder isoStore = await ApplicationData.Current.LocalFolder.GetFolderAsync("Shared");
            var file = await isoStore.CreateFileAsync("foos1.wmv", CreationCollisionOption.ReplaceExisting);
            using (var s = await file.OpenAsync(FileAccessMode.ReadWrite))
            {
                Windows.Foundation.Size resolution = new Windows.Foundation.Size(640, 480);
                avDevice = await AudioVideoCaptureDevice.OpenAsync(CameraSensorLocation.Back,
                    AudioVideoCaptureDevice.GetAvailableCaptureResolutions(CameraSensorLocation.Back).Last());

                VideoBrush videoRecorderBrush = new VideoBrush();
                videoRecorderBrush.SetSource(avDevice);

                viewfinderRectangle.Fill = videoRecorderBrush;

                await avDevice.StartRecordingToStreamAsync(s);

                Thread.Sleep(30000);


                await avDevice.StopRecordingAsync();



            }


            new MediaPlayerLauncher()
            {
                Media = new Uri(file.Path, UriKind.Relative),
            }.Show();
