是否还有其他代码?请考虑并非所有浏览器都支持此功能，也不是所有浏览器都支持所有格式.

video标记是在HTML5中引入的.因此，它将仅在支持HTML5的浏览器中显示.

对于其他浏览器，您可以使用Flash视频.但这需要用户安装Flash Player.实施起来很棘手. (老实说，我不知道如何使用Flash播放音频/视频，我只是知道可以做到.)

The video tag was introduced in HTML5. So it will only be displayed in HTML5 supported browsers.

For other browsers, you can use flash videos. But this requires users to install the flash player. And that is tricky to implement. (Honestly I do not know how to play audio/video using flash, I just know it can be done.)
