Mp4视频无法在iPad上播放 [英] Mp4 video won't play in the iPad
问题描述
美好的一天，我一直致力于这个项目并学习如何在ipad和所有其他浏览器上放置视频。
Good day, I've been working on this project and learning how to place a video on the ipad, and all the other browsers.
但写完之后对于这个代码，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，视频不会播放。奇怪的是，脚本有一个autoplay命令。
But after writing the code for this, I noticed that the only thing I get from the iPad is the first keyframe of the video, but the video is not playing. When I press the "Play" button that appears in that screen of the ipad, the video won't just play. Weird is, the script has an autoplay command.
这个脚本有什么问题？有更好的方法吗？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。
What is wrong with this script ? Is there a better way of doing this ? I've spent way too much time on this and I can't get it done. I checked this on Safari for Windows, Firefox, Internet Explorer and it works everywhere except for the iPad.
<video controls width="920px" height="560px" autoplay>

<source src="video.ogv" type="video/ogg" />
<!--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.)-->
