具有FLVPlayback的AS3视频播放

Question

I am using the code below to load some data from an .xml file. I am preloading all data (Audio Paths, Video Paths including a video from xml.

When everything is loaded complete i am loading the video in Frame 2 on FLVPlayback 2.5 with this code:

videoPlayer.source = videofile;

The problem is that the video shows a white screen for 3-4 seconds and then starts play. At some other pc's it plays normaly when the loading ends.

My Code:

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();

var myLoader:URLLoader = new URLLoader();
//myLoader.load(new URLRequest("myxml.php"));
myLoader.load(new URLRequest("myxml.xml"));
myLoader.addEventListener(Event.COMPLETE, processXML);

function processXML(e:Event):void{

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

}

function assetProgressHandler(evt:ProgressEvent):void{

    var bt:uint = evt.bytesTotal;
    var perEachAssets = 1/assetsList.length;

    var assetsBlLoaded = ((bl / bt)*perEachAssets)+((assetsCtr)/assetsList.length*100)/100;
    var _percentLoaded = Math.floor(assetsBlLoaded*100);

    progBar.setProgress(_percentLoaded,100)
    //trace("_percentLoaded:",_percentLoaded)

Answer 1

Rather than adding the component directly to the stage you might want to try creating and adding it with ActionScript.

By doing this you can instantiate the FLVPlayback instance before you need to show it, rather than having to wait until you hit frame 2 on your timeline.

I can't guarantee it will fix your problem but it's worth a go.

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);
