有没有办法用 as3 预加载和播放 flash 中的 mp4 视频文件?
我尝试了以下方法,但没有任何运气:
var myMovie:Sprite;
var l:Loader = new Loader();
l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loop, false, 0, true);
l.contentLoaderInfo.addEventListener(Event.COMPLETE, done, false, 0, true);
l.load(new URLRequest("video.mp4"));
function loop(e:ProgressEvent):void
{
var perc:Number = e.bytesLoaded / e.bytesTotal;
percent.text = Math.ceil(perc*100).toString();
}
function done(e:Event):void
{
removeChild(percent); // was removeChildAt(0) but it make more sense this way
percent = null;
myMovie = Sprite(l.content);
addChild(myMovie);
l.contentLoaderInfo.removeEventListener( ProgressEvent.PROGRESS, loop);
l.contentLoaderInfo.removeEventListener(Event.COMPLETE, done);
l = null;
}
