javascript – Mp4视频无法在iPad上播放

但在为此编写代码之后,我注意到我从iPad获得的唯一内容是视频的第一个关键帧,但视频没有播放.当我按下ipad屏幕上显示的“播放”按钮时,视频将不会播放.奇怪的是,脚本有一个autoplay命令.

这个脚本有什么问题？有没有更好的方法呢？我花了太多时间在这上面,我无法完成它.我在Safari for Windows,Firefox,Internet Explorer上检查了这个,除了iPad之外,它可以在任何地方使用.

<video controls width="920px" height="560px" autoplay>

<!--If the browser doesn't understand the <video> element,then reference a Flash file. You Could also write something like "Use a Better Browser!" if you're feeling nasty. (Better to use a Flash file though.)-->
