firefox冻结的HTML5视频，不会降级为Flash

Question

我正在使用Video JS播放器播放视频。 一切都是Firefox的绝佳选择。 我已经阅读了很多有关HTML5视频和具有正确MIME类型的问题。 测试Video JS播放器时，它可以正确处理其来源的视频，而不是我的视频。 这是因为我的服务器不支持MIME类型，还是我的代码有错误？

谢谢！

HTML：

<video id="example_video_1" class="video-js" width="780" height="520" autoplay="auto" loop="loop" poster="Images/home.jpg"> 
            <source src="Video/fernando.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' /> 
            <source src="Video/fernando.webm" type='video/webm; codecs="vp8, vorbis"' /> 
            <source src="Video/fernando.ogv" type='video/ogg; codecs="theora, vorbis"' /> 
        <!-- Flash Fallback -->
            <object id="flash_fallback_1" class="vjs-flash-fallback" width="780" height="520" type="application/x-shockwave-flash" data="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf"> 
                <param name="movie" value="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf" /> 
                <param name="allowfullscreen" value="false" /> 
                <param name="flashvars" value='config={"playlist":["Images/home.jpg", {"url": "Video/fernando.mp4","autoPlay":true,"autoBuffering":true, onBeforeFinish: function() { return false; }, wmode: 'opaque'}]}' /> 
                <img src="Images/home.jpg" width="780" height="520" alt="Poster Image" title="No video playback capabilities." /> 
            </object> 
        </video> 

Javascript：

    VideoJS.setupAllWhenReady({
    controlsBelow: false, // Display control bar below video instead of in front of
    controlsHiding: true, // Hide controls when mouse is not over the video
    defaultVolume: 0.85, // Will be overridden by user's last volume if available
    flashVersion: 9, // Required flash version for fallback
    linksHiding: true // Hide download links when video is supported
});

尝试将它们放在您的.htaccecss文件中

AddType video / mp4 .mp4

AddType video / ogg .ogv

AddType video / webm .webm
