Question

我使用下面的代码从.xml文件加载一些数据。我正在预加载所有数据（音频路径，视频路径，包括来自xml的视频。

当所有内容都加载完成后，我将使用以下代码在FLVPlayback 2.5上的第2帧中加载视频：

videoPlayer.source = videofile;

问题是视频显示白屏3-4秒然后开始播放。在其他一些电脑上，当装载结束时，它会正常播放。

我的代码：

import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.media.Sound;
import flash.media.SoundChannel;


stop();

function processXML(e:Event):void{

    var myXml:XML = new XML(e.target.data);
    parseXML(myXml); 
}

您可能希望尝试使用ActionScript创建和添加组件，而不是直接将组件添加到舞台上。

通过执行此操作，您可以在需要显示之前实例化FLVPlayback实例，而不必等到时间线上的第2帧。

我不能保证它会解决您的问题，但值得一试。

var _videoFLV:FLVPlayback;
_videoFLV = new FLVPlayback();
_videoFLV.fullScreenTakeOver = false;
_videoFLV.autoPlay = false;
_videoFLV.autoRewind = true;
_videoFLV.isLive = false;
_videoFLV.skin = null;      
_videoFLV.bufferTime = .1;
_videoFLV.width = 320;
_videoFLV.height = 240;
_videoFLV.source = videofile;
_videoFLV.stop();
_videoFLV.x = 240;
_videoFLV.y = 240;
addChild(_videoFLV);

使用FLVPlayback进行AS3视频播放
