<video src="test.mp4" controls width="320" height="240">
</video>
In chrome,the video plays without any problem.

在chrome，视频播放没有任何问题。但是，mp4 文件在firefox.It 中无法识别。它显示错误消息-'no video with supported format or mimetype found'.
It so happens that most of my video files are .mp4 or .flvfiles.
碰巧我的大部分视频文件都是.mp4 or .flv文件。
If I put
<source src="test.flv" />in the video element ,then both chrome and firefox fail to show it.
如果我放入
<source src="test.flv" />视频元素，那么 chrome 和 firefox 都无法显示它。
So,what should I do to play at least mp4 and flv files in both browsers?.

From Mozilla's page on browser-supported audio/video formats:
从 Mozilla 的关于浏览器支持的音频/视频格式的页面：
The MPEG container format with the H.264 video codec and either the AAC audio codec or the MP3 audio codec is supported by Internet Explorer and Safari. Firefox and Opera do not support the format. Support for the format is deprecated in Chrome, and Chromium does not support it either.
The MPEG media formats are covered by patents, which are not freely licensed. All the necessary licenses can be bought from MPEG LA. Since H.264 is currently not a royalty free format, it is unfit for the open web platform, according to Mozilla [1, 2], Google [1, 2] and Opera.
Internet Explorer 和 Safari 支持带有 H.264 视频编解码器和 AAC 音频编解码器或 MP3 音频编解码器的 MPEG 容器格式。Firefox 和 Opera 不支持该格式。Chrome 已弃用该格式，Chromium 也不支持该格式。
MPEG 媒体格式受专利保护，不能自由授权。所有必要的许可证都可以从 MPEG LA 购买。根据 Mozilla [1, 2]、Google [1, 2] 和 Opera 的说法，由于 H.264 目前不是免版税格式，因此不适合开放网络平台。
Short answer, Firefox doesn't support mp4, as it's not open source. But it does support multiple sources and will play the first one it supports.
简短的回答，Firefox 不支持 mp4，因为它不是开源的。但它确实支持多个来源，并且会播放它支持的第一个来源。
Further, it doesn't appear that swf or flv are supported by any browsers, since they are totally Adobe and require Flash Player, but the following should work around that:
此外，似乎没有任何浏览器支持 swf 或 flv，因为它们完全是 Adobe 并且需要 Flash Player，但以下应该解决这个问题：
<video src="test.mp4" controls>
<object data="test.flv" type="application/x-shockwave-flash">
<param value="test.flv" name="movie"/>
</object>
</video>
Be aware that the above had .swffile as data and value originally; I haven't tested if .flvwill work on its own.
请注意，上面的.swf文件最初是作为数据和值的；我还没有测试过是否.flv可以单独工作。
