Answer 1

1，服务器端可以空实现ApplicationAdapter：示例如下：
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：
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" applicationComplete="init()">
<mx:Script>
<!--[CDATA[
import flash.net.NetConnection;
import flash.net.NetStream;
import flash.events.NetStatusEvent;
import mx.controls.Alert;

private var nc:NetConnection;
private var ns:NetStream;
private var cam:Camera;

private function init():void{
nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS,connectServerHander);
nc.client = this;
nc.connect("rtmp://58.116.56.68:1935/Flex01");
}

private function connectServerHander(evt:NetStatusEvent):void{
trace(evt.info.code);
cam = Camera.getCamera();

if(cam != null){
cam.setMode(313,194,30);
cam.setQuality(0,70);
ns = new NetStream(nc);
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");
}
}

public function onBWDone():void{

}

<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：
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" applicationComplete="init()">

<mx:Script>
<!--[CDATA[

import flash.display.*;
import flash.utils.*;
import flash.events.*;
import flash.net.*;
import flash.media.Video;
import flash.media.Camera;

private var nc:NetConnection;

private function init():void{
nc = new NetConnection();
nc.connect("rtmp://58.116.56.68:1935/Flex01");
nc.addEventListener(NetStatusEvent.NET_STATUS,connectHandler);
}

private function connectHandler(evt:NetStatusEvent):void{

var ns:NetStream = new NetStream(nc);
var video:Video=new Video() ;
video.width = 313;
video.height = 194;
video.attachNetStream(ns);
ns.play("red5");
videoDisplay.addChild(video);
