本文介绍了一个使用Flash实现视频录制和回放的示例代码。通过创建Flash组件如输入文本框和按钮，并利用NetStream和Camera API进行视频流的发布和播放。然而，在播放过程中遇到了错误提示，涉及NetStream调用回调失败的问题。

在舞台上从组件中拖出输入文本框，三个按钮，分别命名：

tbName,btnPublish,btnStop,btnPlay

package
{
     import flash.net.*;
     import flash.events.*;
     import flash.media.*;

     public class PublishPlay extends Sprite
    {
        private var nc:NetConnection;
        private var ns:NetStream;
        private var video:Video;
        private var cam:Camera;
        private var mic:Microphone;

        public function PublishPlay():void
        {
            tbName.text="请输入视频文件名:";
            btnPublish.label="开始录制";
            btnPublish.addEventListener(MouseEvent.CLICK,onPublishClick);
            btnStop.label="停止录制";
            btnStop.addEventListener(MouseEvent.CLICK,onStopHandler);
            btnPlay.label="视频回放";
            btnPlay.addEventListener(MouseEvent.CLICK,onPlayHandler);

            video=new Video();
            cam = Camera.getCamera();
            mic = Microphone.getMicrophone();
            if(cam==null)
            {
                trace("没检测到视频摄像头");
            }
            else
            {
                video.attachCamera(cam);
            }
            addChild(video);
        }

        private function onStatusHandler(evt:NetStatusEvent):void
        {
            trace(evt.info.code);
            if(evt.info.code=="NetConnection.Connect.Success")
            {
                ns=new NetStream(nc);
                ns.addEventListener(NetStatusEvent.NET_STATUS,onStatusHandler);
                ns.client=new CustomClient();
            }
        }

        private function onPublishClick(evt:MouseEvent):void
        {
            nc=new NetConnection();
            nc.addEventListener(NetStatusEvent.NET_STATUS,onPublishStatusHandler);
            nc.connect("rtmp://localhost/firstfmsapp");
        }

        private function onPublishStatusHandler(evt:NetStatusEvent):void
        {
            if(evt.info.code=="NetConnection.Connect.Success")
            {
                ns=new NetStream(nc);
                ns.addEventListener(NetStatusEvent.NET_STATUS,onPublishStatusHandler);
                ns.client=new CustomClient();
                ns.attachCamera(cam);
                ns.attachAudio(mic);
                ns.publish(tbName.text,"record");
            }
        }

        private function onStopHandler(evt:MouseEvent):void
        {
            nc.close();
        }

        private function onPlayHandler(evt:MouseEvent):void
        {
            nc=new NetConnection();
            nc.addEventListener(NetStatusEvent.NET_STATUS,onPlayStatusHandler);
            nc.connect("rtmp://localhost/firstfmsapp");
        }

        private function onPlayStatusHandler(evt:NetStatusEvent):void
        {
            if(evt.info.code=="NetConnection.Connect.Success")
            {
                ns=new NetStream(nc);
                ns.addEventListener(NetStatusEvent.NET_STATUS,onPlayStatusHandler);
                ns.client=new CustomClient();

                video = new Video();
                video.attachNetStream(ns);
                ns.play(tbName.text,0);
                addChild(video);
            }
        }
    }
}

代码中的目录要先手动简历，然后录制的视频片段就会保存在该目录下，

但是根据教程，播放结束后会提示出错：

Error #2044: 未处理的 AsyncErrorEvent:。 text=Error #2095: flash.net.NetStream 无法调用回调 onPlayStatus。 error=ReferenceError: Error #1069: 在 CustomClient 上找不到属性 onPlayStatus，且没有默认值。
