导读：1，服务器端可以空实现ApplicationAdapter：示例如下： ? [java] ? view plain copy package ?org.chy.flex01;?? ?? import ?org.red5.server.adapter.ApplicationAdapter;?? public ? class ?Application? extends ?ApplicationAdapter{?? ?????? ?? }?? 客

1，服务器端可以空实现ApplicationAdapter：示例如下：

[java]? 
   view plain 
   copy 
    
   
 package?org.chy.flex01;??
 ??
import?org.red5.server.adapter.ApplicationAdapter;??
public?class?Application?extends?ApplicationAdapter{??
 ??????
 ??
 }??

客户端使用Flex实现摄像头获取视频并发布代码如下：

[javascript]? 
   copy

<?xml?version="1.0"?encoding="utf-8"?>??

<mx:Application?xmlns:mx="http://www.adobe.com/2006/mxml"?layout="absolute"?applicationComplete="init()">??

????????????????nc.addEventListener(NetStatusEvent.NET_STATUS,connectServerHander);??

????????????}??
??????????????
function?connectServerHander(evt:NetStatusEvent):void{??

????????????????cam?=?Camera.getCamera();??

????????????????????ns.attachCamera(cam);??
????????????????????ns.publish("red5");??
??????????????????????
????????????????????var?vi:Video?=?new?Video();??
????????????????????vi.width?=?313;??
????????????????????vi.height?=?194;??
????????????????????vi.attachCamera(cam);??
????????????????????videoDisplay.addChild(vi);??
????????????????}else{??
????????????????????Alert.show("no?Camera");??
????????????????}??

????</mx:Script>??
??????
????<mx:VideoDisplay?x="162"?y="77"?width="313"?height="194"?id="videoDisplay"/>??
</mx:Application>??

客户端使用Flex play视频代码如下：

copy 
    
   

????<mx:Script>??

????????<!--[CDATA[??

????????????????video.attachNetStream(ns);??
????????????????ns.play("red5");??
????????????????videoDisplay.addChild(video);??
