据说html5test.com,chrome不支持html5 mp4视频(见以下链接).
http://html5test.com/compare/feature/video-mpeg4.html
但是,在此测试页面中,可以通过将主体设置如下来成功播放mp4视频:
<!DOCTYPE html>
<html>
<body>
<video width="320" height="240" controls="controls">
<source src="movie.mp4" type="video/mp4" />
Your browser does not support the video tag.
</video>
</body>
</html>
我怎样才能正确解释这个？
