将视频控件添加到 XML 组合框选择的视频时遇到问题

Question

我已经更接近我最终想要的结果了，谢谢。

剩下的两个问题是，当我点击上一个和下一个时，组合框中显示的名称有时会不同步。

而且我似乎无法让视频洗涤器工作。

你好，自从我接触闪光灯以来已经有几年了，所以也许我只是忽略了一些东西。如果有人可以查看代码并提供任何建议，那就太棒了。

工作原理是，我从由 XML 文件填充的组合框中选择一个视频，选择该视频并播放。

我一直在尝试添加暂停/播放、停止、前进和后退功能，一旦我开始工作，我还想添加一个视频洗涤器（滑块）和上一个/下一个按钮以转到上一个/下一个视频xml 文件中列出。

目前，我在舞台上有一个名为 playButton 的组件按钮，我试图将其用于暂停/播放功能。下面是我的代码，播放器控件位于最底部。谢谢。

import fl.data.DataProvider;

var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
var videosXML:XML = new XML();
var loader:URLLoader = new URLLoader();
var request:URLRequest= new URLRequest("xml/videos.xml");
var videos:Array = new Array({label:"Select a Video",data:""});
var client:Object = new Object();  

theVideo.attachNetStream(ns);
ns.client = client;
 loader.addEventListener(Event.COMPLETE,loaderOnComplete);
 loader.load (request);

function loaderOnComplete(event:Event):void{
    videosXML = new XML(event.target.data); 
    for each (var video:XML in videosXML.video){
        videos.push({label:video.name.toString(),data:video.url.toString()});
    }
    moviesCB.dataProvider = new DataProvider(videos);
}

moviesCB.addEventListener(Event.CHANGE, changeHandler);

function changeHandler(event:Event):void {
    if(ComboBox(event.target).selectedItem.data != ""){
        ns.play(ComboBox(event.target).selectedItem.data);
    }
};

client.onMetaData = metadataHandler;
function metadataHandler(md:Object):void{
}

//player controls
playButton.onRelease = function() {
    ns.pause();
}

Answer 1

我想你想这样做（点击处理程序在AS3中是不同的）

playButton.addEventListener(MouseEvent.CLICK, onTogglePlay);

function onTogglePlay(e:MouseEvent):void {
   ns.togglePause();
}

你应该在NC上为NetStatusEvent放置一个监听器，然后在连接连接后创建NetStream。

Answer 2

我原来问题的答案是使用stream.bytesTotal和stream.bytesLoaded而不是ns.bytesTotal和ns.bytesLoaded
