AS3.0加载FLV视频

//打开连接
var nc:NetConnection = new NetConnection();
nc.connect (null);

//提取 flv视频
var ns:NetStream = new NetStream(nc);
ns.play ("laislabonita.flv");

//显示 flv视频
var vid:Video = new Video();
vid.attachNetStream (ns);
addChild (vid);

//处理错误
ns.addEventListener (AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler);
function asyncErrorHandler (event:AsyncErrorEvent):void
{
// 忽略错误
}

///控制影片暂停/播放

pause_btn.addEventListener (MouseEvent.CLICK,mouseRelease);
function mouseRelease (event:MouseEvent)
{
ns.togglePause ();

}

补充：

//onMetaData

var client:Object=new Object();
client.onMetaData = onMetaData;
videoStream.client = client;

function onMetaData(data:Object):void
   {
    _duration = data.duration;

   }
