Screen recording in windows phone 8.1

Question

I am working on an windows phone 8.1 application. Work of this app is to record screen activities and store mp4 file in storage. I do not get any compile time error. But

var screenCapture = ScreenCapture.GetForCurrentView();

line returns me UnauthorizedAccessException. I have already added capabilities for Microphone and Webcam to manifest file. I have also tried calling this code in page constructor and from separate class. I am using HTC 8x device with Windows Phone 8.1 OS

Following is my code block :

async private void Button_Tapped(object sender, TappedRoutedEventArgs e)
{
                var screenCapture = ScreenCapture.GetForCurrentView();

                mediaCapture = new MediaCapture();
                await mediaCapture.InitializeAsync(new MediaCaptureInitializationSettings
                {
                    VideoSource = screenCapture.VideoSource,
                    AudioSource = screenCapture.AudioSource,
                });

                var file = await KnownFolders.VideosLibrary.CreateFileAsync("screenrecording.mp4", CreationCollisionOption.ReplaceExisting);
                await mediaCapture.StartRecordToStorageFileAsync(MediaEncodingProfile.CreateMp4(VideoEncodingQuality.Auto), file);

                //sr.StartRecording();}

Answer 1

You need to check the capabilities for accessing the video library as well.

Hope this helps!
