如何让video.js在Firefox中播放？

我（在帮助下）将video.js播放器添加到网页中，它在除Firefox之外的所有浏览器中都能正常运行。当通过Firefox访问并尝试播放视频时，我看到：“没有找到支持格式和MIME类型的视频”

<object class="vjs-flash-fallback" width="640" height="264" type="application/x-  shockwave-flash" data="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf">
<param name="movie" value="http://url.com/flowplayer/flowplayer-3.2.16.swf" />
<param name="allowfullscreen" value="true" />
<param name="flashvars" value='config={"playlist":["[var.base_url]/[var.thumb_file]",  {"url": "http://url.com/uploads/ [var.video_play]","autoPlay":false,"autoBuffering":true}]}' />
<!-- Image Fallback. Typically the same as the poster image. -->
<img src="[var.base_url]/[var.thumb_file]" width="640" height="264" alt="Poster Image" title="No video playback capabilities." />
</object>
</video> 

这是我的播放器代码：

<object class="vjs-flash-fallback" width="640" height="264" type="application/x-  shockwave-flash" data="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf">
<param name="movie" value="http://url.com/flowplayer/flowplayer-3.2.16.swf" />
<param name="allowfullscreen" value="true" />
<param name="flashvars" value='config={"playlist":["[var.base_url]/[var.thumb_file]",  {"url": "http://url.com/uploads/ [var.video_play]","autoPlay":false,"autoBuffering":true}]}' />
<!-- Image Fallback. Typically the same as the poster image. -->
<img src="[var.base_url]/[var.thumb_file]" width="640" height="264" alt="Poster Image" title="No video playback capabilities." />
</object>
</video>

如有任何建议/想法/补救措施，将不胜感激

尝试将代码更改为：

<object class="vjs-flash-fallback" width="640" height="264" type="application/x-  shockwave-flash" data="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf">
<param name="movie" value="http://url.com/flowplayer/flowplayer-3.2.16.swf" />
<param name="allowfullscreen" value="true" />
<param name="flashvars" value='config={"playlist":["[var.base_url]/[var.thumb_file]",  {"url": "http://url.com/uploads/ [var.video_play]","autoPlay":false,"autoBuffering":true}]}' />
<!-- Image Fallback. Typically the same as the poster image. -->
<img src="[var.base_url]/[var.thumb_file]" width="640" height="264" alt="Poster Image" title="No video playback capabilities." />
</object>
</video> 

<video id="myMovie" class="video-js vjs-default-skin" controls preload="auto" width="640" height="264">
    <source src="/path/mymovie.mp4" type='video/mp4' />
            <source src="/path/mymovie.webm" type='video/webm' />
</video>

video.js应该处理所有必要的回退废话，这些废话让嵌入视频成为一天中的一件头痛事

<object class="vjs-flash-fallback" width="640" height="264" type="application/x-  shockwave-flash" data="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf">
<param name="movie" value="http://url.com/flowplayer/flowplayer-3.2.16.swf" />
<param name="allowfullscreen" value="true" />
<param name="flashvars" value='config={"playlist":["[var.base_url]/[var.thumb_file]",  {"url": "http://url.com/uploads/ [var.video_play]","autoPlay":false,"autoBuffering":true}]}' />
<!-- Image Fallback. Typically the same as the poster image. -->
<img src="[var.base_url]/[var.thumb_file]" width="640" height="264" alt="Poster Image" title="No video playback capabilities." />
</object>
