jwplayer 360p视频需要加载

Question

我的插件jwplayer有问题 他在我的localhost上有2个中等240p和360p它正常运行。 但是当发送到主机需要太长时间以240p加载360p的视频时，加载速度更快，实际上我认为他正在等待加载整个视频。

我的代码：

<script type="text/javascript">
    jwplayer("container").setup({
    height: "97%",
    width: "100%",
    primary: "flash",
    allowscriptaccess: "always",
    autostart:true,

  playlist: [{
      image: "uploads/snapshots/374f9c59b58f880c5e68762bde43318a.jpg",
    sources: [{
      file: "uploads/374f9c59b58f880c5e68762bde43318a.mp4",
      label: "360p"
    },{
      file: "uploads/374f9c59b58f880c5e68762bde43318a.flv",
      label: "240p"
    }]
  }],  
});
</script>
