没有专用的暂停按钮-相反，单击播放按钮后会用暂停按钮进行切换.另请参见w3schools.com上的示例:

There is no dedicated pause button - instead the play button is toggled with a pause button after it's clicked. See also the example at w3schools.com:

添加:

这在您的代码中:

<source src="my_location.ogv" type="video/ogv" />

应该是

<source src="my_location.ogv" type="video/ogg" />.

(文件类型为ogg，而不是ogv，而不是文件扩展名本身.)

(ogg instead of ogv on the file type / not on the file extension itself).
