    I have two separate code: one for continuous flashlight on and second for video capture. when i run these codes in different project it gives proper output. but the problem occurs when i combine these codes in one project.

    In first code which gives continuous flashlight on i have used "_videoCameraVisualizer.SetSource (_videoCamera1);" where _videoCameraVisualizer is object of VideoCameraVisualizer class and _videoCamera1 is object of VideoCamera class. I have use System.Reflection namespace in this project.

    in second code which displays video capture i have used "video.SetSource(source);" where video is object of VideoBrush class and source is object of CaptureSource class.

    when I combine this codes the flashlight remains on continuously but got error at "source.Start();". The error is "NotSupportedException was unhandled - 0x80131515".

    I want coutinuous flashlight on with video capturing. For continuous flashlight I got this link : Locked So I have used this. and for video Capture i have used CaptureSource class and following code on button_click :

    if (ispressvideo == false)
    ispressvideo = true;
    if (source != null)

    source = new CaptureSource();
    source.VideoCaptureDevice = CaptureDeviceConfiguration.GetDefaultVideoCaptureDevice();
    source.AudioCaptureDevice = CaptureDeviceConfiguration.GetDefaultAudioCaptureDevice();

    VideoBrush video = new VideoBrush();
    CaptureDisplay.Fill = video;

    if (CaptureDeviceConfiguration.AllowedDeviceAccess || CaptureDeviceConfiguration.RequestDeviceAccess())
    //_videoCamera1 = null;
    source.Start();// Error comes at this place

    I am trying to solve this error from last two days but can not understand what is the problem. :(

    Thanks in advance.
