使用Adobe AIR捕获和流视频

Question

我正在尝试通过网络摄像头捕获视频并使用AIR将其转换为RTMP流。但我无法找到像这样的任何示例。是否有任何方法可以这样做？请给我一些例子来实现这一点。我是ActionScript的新手，我在ActionScript中做过，我已经看到ActionScript中的Camera api，但它不起作用可能是我错误地实现。

最后我找到了一种方法来捕捉网络摄像头视频和流it.As我说我要它，它AIR所以我创建了一个ActionScript类来解决这个。

package { 
    import flash.display.Sprite; 
    import flash.events.NetStatusEvent; 
    import flash.media.Camera; 
    import flash.media.Microphone; 
    import flash.media.Video; 
    import flash.net.NetConnection; 
    import flash.net.NetStream; 
    import flash.net.Responder; 
    import flash.text.TextField; 

    /**0... 
    * @author BECKER Christophe

    public class Main extends Sprite { 
     // 
     public var vid : Video; 
     public var cam : Camera; 
     public var bt : Sprite; 
     public var txt : TextField ; 
     public var microphone : Microphone; 
     private var connection:NetConnection; 

     private var outStream:NetStream; 
     public var nc : NetConnection; 
     public var responder : Responder; 
     private var inStream:NetStream; 
     private var inVideo:Video; 
     public function Main() { 
      connection = new NetConnection(); 
      connection.client = { onBWDone: function():void{ trace("onBWDone") } }; 
      connection.connect("rtmp://Ipaddress/TestApp"); 
      connection.addEventListener(NetStatusEvent.NET_STATUS, onConnected); 

     } 
      private function onConnected(event:NetStatusEvent):void { 
     if(event.info.code == "NetConnection.Connect.Success") { 

      if(Camera.names.length>0){ 
       cam = Camera.getCamera(); 
       cam.setMode(640, 480, 15); 
      } 
      if(Microphone.names.length>0) 
       microphone = Microphone.getMicrophone(); 

      outStream = new NetStream(connection); 
      outStream.attachCamera(cam); 
      outStream.attachAudio(microphone); 
      outStream.publish("DemoVideo1","live"); 


      vid = new Video(300, 300); 
      vid.attachCamera(cam); 
      addChild(vid); 

//   inStream = new NetStream(connection); 
//   inStream.play("DemoVideo1"); 

//   inVideo = new Video(250,250); 
//   inVideo.attachNetStream(inStream); 

//   addChild(inVideo); 



          } 
     } 


     private function metaDataHandler(meta : Object) : void { 
      if (vid) { 
       vid.width = meta.width; 
       vid.height = meta.height; 
      } 
     } 

    } 
}
