闪光流麦克风（不带凸轮）

Question

我如何修改此代码，如果我不想使用网络摄像头，只使用麦克风？

我想如果它运行没有打开相机。

谢谢，

private function InitCameraAndMicrophone():void {               
m_Microphone = Microphone.getEnhancedMicrophone(this.cameraSettingsDialog.dropDownListMicrophones.selectedIndex);
var options:MicrophoneEnhancedOptions = new MicrophoneEnhancedOptions();
options.mode = MicrophoneEnhancedMode.FULL_DUPLEX;
options.autoGain = true;
options.nonLinearProcessing = true;
m_Microphone.enhancedOptions = options;
m_Microphone.codec = "Speex";
m_Microphone.encodeQuality = 10; 
m_Microphone.setUseEchoSuppression(true);

memberCamera = Camera.getCamera(this.cameraSettingsDialog.dropDownListCameras.selectedIndex.toString());    

if (memberCamera == null) 
{
    var informationTitle:String = localizatonProvider.localize('flash_information');
    var alertMessage:String = localizatonProvider.localize('flash_connect_your_camera');
    CommonHelper.javascriptFunctionCallWrap("jAlert", alertMessage + ';' + informationTitle);
    return;
}
memberCamera.setMode(this.cameraSettingsDialog.selectedResolution.x, this.cameraSettingsDialog.selectedResolution.y, 15);
memberCamera.setQuality(0, 90);
memberCamera.setKeyFrameInterval(100); */
memberVideo = new Video(405, 305);
memberVideo.attachCamera(this.memberCamera);

this.stateWhenStartedCamToCam = this.currentState;

if(userAllowedCameraAccess)
{
    ConnectCamToCam();
}
memberCamera.addEventListener(StatusEvent.STATUS, memberCameraStatusHandler);

}
