Flash流式麥克風（不帶凸輪）

Question

我如何修改此代碼，如果我希望它不使用網絡攝像頭，只能使用麥克風？

我想如果它運行不打開相機。

感謝，

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); 

}
