AsyncErrorEvent:。 text=Error #2095: flash.net.NetStream 无法调用回调 onMetaData。 error=ReferenceError: Error
问题：Error #2044: 未处理的 AsyncErrorEvent:。 text=Error #2095: flash.net.NetStream 无法调用回调 onMetaData。 error=ReferenceError: Error #1069:找不到属性 onMetaData，且没有默认值。
解决方法：
加载并播放外部flv文件，想获取总时间，得如上错误提示。
// 创建回调函数的对象
var customClient:Object = new Object();
customClient.onMetaData = metaDataHandler;
// 赋值给NetStream对象的属性client
var my_nc:NetConnection=new NetConnection();
my_nc.connect(null);
var my_ns = new NetStream(my_nc);
my_ns.client = customClient;
my_ns.play("mov1.flv");
//onMetaData回调函数的事件
function metaDataHandler(infoObject:Object):void {
//获得flv文件中嵌入的描述性信息，这里获得获得总持续时间（单位：秒）
var flv_duration:Number = int(infoObject.duration);
var tM:Number = Math.floor(flv_duration/60);
var tS:Number = Math.floor(flv_duration%60);
time_txt.text="总长："+tM+":"+tS;
}
红色为解决问题的部分
