我正在尝试使用video-js嵌入html5视频

<video id="example_video_1" class="video-js" width="450" height="300" controls="controls" preload="auto" poster="http://video-js.zencoder.com/oceans-clip.png">
     <source src="/images/video/iphone.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' />
     <source src="/images/video/test.webm" type='video/webm; codecs="vp8, vorbis"' />
     <source src="/images/video/test.ogv" type='video/ogg; codecs="theora, vorbis"' />
     <!-- Flash Fallback. Use any flash video player here. Make sure to keep the vjs-flash-fallback class. -->
     <object id="flash_fallback_1" class="vjs-flash-fallback" width="450" height="300" 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="true" />
        <param name="flashvars" value='config={"playlist":["http://video-js.zencoder.com/oceans-clip.png", {"url": "http://video-js.zencoder.com/oceans-clip.mp4","autoPlay":false,"autoBuffering":true}]}' />
        <!-- Image Fallback. Typically the same as the poster image. -->
        <img src="http://video-js.zencoder.com/oceans-clip.png" width="450" height="300" alt="Poster Image"
                    title="No video playback capabilities." />
     </object>
