Flex 4 Spark 视频播放器如何从当前时间开始播放

Question

有 4 个视频源，以便用户可以在视频源之间切换，视频进度相同。

我怎样才能实现这个？ 函数 seek(time:duration):void 并没有真正起作用。 :-(

我使用的代码：

<?xml version="1.0" encoding="utf-8"?>

<fx:Script>
    <![CDATA[
        import mx.events.VideoEvent;

        import org.osmf.media.MediaPlayer;
        import org.osmf.video.CuePoint;

        protected function button1_clickHandler(event:MouseEvent):void
        {
            var playing:Boolean=VideoPlr.playing;
            var time:Number = VideoPlr.currentTime;
            VideoPlr.source = "http://helpexamples.com/flash/video/water.flv";
            // dosn't work this.VideoPlr.seek(VideoPlr.duration * time / 100);
            if(playing) VideoPlr.play();
        }


        protected function button2_clickHandler(event:MouseEvent):void
        {
            var playing:Boolean=VideoPlr.playing;
            var time:Number = VideoPlr.currentTime;
            VideoPlr.source = "http://helpexamples.com/flash/video/clouds.flv";
            // dosn't work this.VideoPlr.seek(VideoPlr.duration * time / 100);

            if(playing) VideoPlr.play();
        }


        protected function button3_clickHandler(event:MouseEvent):void
        {
            var playing:Boolean=VideoPlr.playing;
            var time:Number = VideoPlr.currentTime;
            VideoPlr.source = "http://helpexamples.com/flash/video/cuepoints.flv";
            // dosn't work this.VideoPlr.seek(VideoPlr.duration * time / 100);
            if(playing) VideoPlr.play();
        }


        protected function button4_clickHandler(event:MouseEvent):void
        {
            var playing:Boolean=VideoPlr.playing;
            var time:Number = VideoPlr.currentTime;
            //VideoPlr.source = "http://helpexamples.com/flash/video/cuepoints.flv";
            if(playing) VideoPlr.play();
        }

<s:VideoPlayer x="26" y="10" height="588" width="1081" autoPlay="false" 
               source="http://helpexamples.com/flash/video/water.flv" 
              id="VideoPlr" muted="false" pauseWhenHidden="true" 

在期待中感谢你

这是我的解决方案：

有四个文件可以在您的设计中切换。每个开关都会跳转到新源文件中的时间。
