我尝试了几种方法,但没有人使用
html5播放file2.m4v看屏幕截图.
但是,如果我使用VLC / Mplayer使用相同的文件,它可以很好地播放电影(没问题).请参阅以下代码和文件详细信息以查找其使用的代码：
video.PHP：
<html>
<head>
</head>
<body>
<video preload="auto" autoplay="autoplay" controls>
<source
src="/var/www/html/video/file2.m4v"
type='video/mp4; codecs="avc1.42E01E,mp4a.40.2"'>
</video>
</body>
</html>
找到文件音频/视频编解码器：

还有什么我可以用来在浏览器中播放这个文件？是否有任何javascript播放器也可用html5无法播放它？
HTML5视频只是一种使用新元素播放某些视频格式的惯例,浏览器将为其实现自己的播放器. HTML5不会提供播放器或类似的东西.
您必须查找大多数浏览器支持的编解码器,如果我记得很清楚,那么在OGG容器中,主要是Theora for Video和Vorbis for audio.
然后我记得Webkit浏览器将支持使用V8作为视频编解码器的Matroska(MKV)容器和用于音频的Vorbis.
我的建议：分别将Theora和Vorbis的OGG文件作为视频和音频编解码器提供.内部使用带有V8和Vorbis的MKV文件提供后备,然后,如果可以的话,使用Mpeg2和MP2(无法想象更好的东西)作为视频和音频编解码器的内部MPG视频文件,后备.
然后作为最后一个后备,Flash播放器播放FLV视频文件.
HTML示例的示例：
<video src="thevideo.ogg">
<video src="firstFallback.mkv">
<object type="video/mpeg" src="secondFallback.mpeg">
<object
type="application/x-shockwave-flash"
src="player.swf?etc...">
<p>Download <a href="videourl">the video etc...</a><br />
or use a more modern browser to watch online,etc...</p>
</object>
</object>
</video>
</video>
等……
