flash - 如何将 netstream.appendBytes() 用于 http 动态流？

Question

我正在尝试了解如何在 Flash 10.1 中使用 http 动态流式传输，但我无法使用基本功能。对视频文件使用 appendbytes 的语法是什么？

package com.player {

import flash.display.Stage;
import flash.net.NetConnection;
import flash.net.NetStream;
import flash.media.Video;
import flash.display.Sprite;
import flash.net.URLRequest;
import flash.net.URLStream;
import flash.events.Event;
import flash.utils.ByteArray;

public class Player extends Sprite {

    const vurl = "file://E:/clip.flv"

    private var nc:NetConnection;
    private var ns:NetStream;
    private var vo:Video;



    private var urlstream:URLStream;

    public function Player() {

        nc = new NetConnection();
        nc.connect(null);

        ns = new NetStream(nc);
        ns.client = new StreamClient();

        vo = new Video();
        vo.attachNetStream(ns);

        addChild(vo);

        ns.play(vurl);

        var urlrequest:URLRequest = new URLRequest(vurl)
         urlstream = new URLStream();

        urlstream.addEventListener(Event.COMPLETE, completeHandler);

        urlstream.load(urlrequest);



    }

    private function completeHandler(event:Event):void {
        trace("completeHandler: " + event);

        var bytes:ByteArray = new ByteArray();

        urlstream.readBytes(bytes);

        ns.appendBytes(bytes);
    }


}

运行这个给我错误:

TypeError: Error #2004: One of the parameters is invalid. at flash.net::NetStream/appendBytes() at ...

我找到了解决问题的办法。你必须从 ns.play(null) 而不是 ns.play('url to download'); 开始;
