php – 如何玩html5视频?当文件是file.m4v?

前端之家收集整理的这篇文章主要介绍了php – 如何玩html5视频?当文件是file.m4v?前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我尝试了几种方法,但没有人使用 html5播放file2.m4v看屏幕截图. @H_301_1@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).请参阅以下代码文件详细信息以查找其使用的代码

<body>

  <video preload="auto" autoplay="autoplay" controls>
    <source 
        src="/var/www/html/video/file2.m4v" 
            type='video/mp4; codecs="avc1.42E01E,mp4a.40.2"'>

@H_301_1@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. @H_301_1@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.

@H_301_1@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.

@H_301_1@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.

@H_301_1@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>
