Questions about recording video

        bool forceDecodeAudio = false;
        bool forceDecodeVideo = false;
        PropertySet options = new PropertySet();
        FFmpegMSS = FFmpegInteropMSS.CreateFFmpegInteropMSSFromUri("udp://192.168.5.2:1008", forceDecodeAudio, forceDecodeVideo);
        if (FFmpegMSS != null)
        {
            var mediaUI = Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
            {
                 mss = FFmpegMSS.GetMediaStreamSource();
                if (mss != null)
                {
                    _mediaPlayer = new MediaPlayer();
                    _mediaPlayerElement.Source = MediaSource.CreateFromMediaStreamSource(mss);
                    _mediaPlayer = _mediaPlayerElement.MediaPlayer;
                    _mediaPlayer.Play();
                    _mediaPlayer.MediaOpened += _mediaPlayer_MediaOpened;


                    var settings = new MediaCaptureInitializationSettings();
                    settings.VideoSource =mss;
                    settings.MediaCategory = MediaCategory.Other;
                    settings.StreamingCaptureMode = StreamingCaptureMode.Video;



                    _mediaCapture = new MediaCapture();
                    await _mediaCapture.InitializeAsync(settings);
                }
            });
        }

Run to _mediaCapture.InitializeAsync (settings); suggested that the error, what is the reason. What should I do? Hope to get everyone's help, very grateful!

Start with the code in the issue and capture the exact error reported at _mediaCapture.InitializeAsync(settings). Read the MediaCapture initialization path and the settings that use the MediaStreamSource, then verify the cause against the FFmpegInterop sample or relevant documentation. Done means identifying the initialization failure and documenting the required correction or missing information.
