试图执行未经授权的操作captureSource.Start（）

问题描述

尝试在Windows手机上捕捉视频时出错。

I'm getting an error while trying to capture video on the windows phone.

我还包括 CaptureDeviceConfiguration 。RequestDeviceAccess（）;

I also included CaptureDeviceConfiguration.RequestDeviceAccess();

if （ CaptureDeviceConfiguration 。RequestDeviceAcces s（）
&& captureSource.VideoCaptureDevice！= null
）

if(CaptureDeviceConfiguration.RequestDeviceAccess() && captureSource.VideoCaptureDevice != null )

{

captureSource.Start（）;

captureSource.Start();

}

推荐答案

这是一个Windows Phone 7.1目标项目/应用程序吗？

Is this a Windows Phone 7.1 targeted project / application?

如果是这样，您是否在代码中引用了Microphone类以确保检测到该功能？   

If so, do you have a reference to the Microphone class in your code to ensure the capability is detected?   

ex：

    public class CapabilityPlaceholder
    {
        Microphone unusedMic = null;

        private string unusedMethod()
        {
            return unusedMic.ToString();
        }
    }
