如何停止嵌入视频的自动播放？

Question

这是我要嵌入的来自 metacafe.com 的视频剪辑：

<!DOCTYPE html>
<html>
<body>

<table>
<tr>
<td>
<iframe 
width="720" height="405" 
src="http://www.metacafe.com/embed/11600739/natasha-the-founder-of-easy-peasy-lemon-squeezy-forms-the-secrets-to-form-a-saas-application-mp4$autoStart=false" 
frameborder="0" webkitAllowFullScreen mozallowfullscreen allowfullscreen>
</iframe>
</td>
</tr>
</table>

</body>
</html>

嵌入没问题，只是剪辑会在页面加载后自动开始播放。我怎样才能在这里停止自动播放？

我尝试了以下选项，但 none 个有效：

我也尝试在所有这些选项中使用 autoPlay 而不是 autoStart，但它也没有帮助。
