我正在使用你正在使用的video.js。我的意思是我下载了zipfile并解压缩到包含所有文件的video-js文件夹中。完美，如果我播放你的demo.html，我可以在FF中正确看到它。我想用view.js从localSD创建一个带jquerymobile的webapp 所以，我在头部设置正确的位置，因为你建议指向本地video-js / video.js我设置了一个海报photo.png位于相同的文件夹video-js。我在Android 4.0.1上进行了测试，当页面处于转换状态时，海报刚刚出现，然后消失，留下一个灰色的矩形，但我在iPad上进行了测试并且可以正常工作。第二个问题是flash播放器，因为我无法在firefox中播放，也没有播放器只显示黑色矩形。也许我必须设置正确的路径。你的视频js.swf在同一个文件夹video-js我需要做什么，我根本不是专家。你能告诉我在哪里可以改变一些东西吗？下面我包含index.html页面，其中包含所有设置（文件名和图片都是正确的）。感谢。

<p><strong><em>Welcome,</em></strong></p>
<p>
Thank you for downloading this first lesson of the Course Media Composer 5.x. My name is Angelo Giammarresi, I'm film director and producer of 90 documentaries around the world, video-editing courses and so on. I set my company, World On Communications, to share my expertises and knowledge acquired since 1978 in TV and multimedia productions, as you can better know visiting <a href="http://www.wocmultimedia.com/" target="blank">www.wcmultimedia.com</a> but, let's go on with the course introduction.</p>
