video视频全屏播放

作点击图片，全屏播放视频，视频播放后显示领一张图片，作到无缝链接避免黑屏，要注意的是

　　1视频须要提早load(),

　　2监听video的playing（）事件，当视频开始播放的时候隐藏视频1的封面图

　　3当视频结束的时候，监听video的ended（）事件，令video.pause(),隐藏video所在的父级div.

　　或者 

　　监听视频播放的时间 ,在视频结束以前 video.pause();如video总长5s,myVid.currentTime>4.2,则video.pause()

代码以下

 

<style>

#start-videobox{

   position: absolute;
   left: 0;
   top: 0;
   right: 0;
   bottom: 0;
   background: #fff url(../images/p1.png) no-repeat 0 0 /100% 100%;
   z-index: 10;
}

#videobox {
   position: absolute;
   left: 0;
   top: 0;
   right: 0;
   bottom: 0;
   overflow: hidden;
}

#videobox video {
   height: 100%;
   width: 100%;
   position: absolute;
   left: 0;
   top: 0;
}
