title: can not find local video by react^15.6.1+webpack2
body: <pre><code>  {
      test: /\.html$/,
      loader: 'html-loader?attrs[]=video:src'
    },
    {
      test: /\.(jpg|png|gif|svg)$/,
      use: [
        {
          loader: "url-loader",
          options: {limit: 8192}
        }
      ]
    },
    {
      test:/\.mp4$/,
      loader: 'url-loader?limit=10000&amp;mimetype=video/mp4'
    }
  </code></pre>
  
  <p>This is what I set in webpack.</p>
  
  <pre><code>&lt;video width="100%" height="100%" src="./1.mp4" controls&gt;
       Your browser does not support HTML5 video.
  &lt;/video&gt;
  </code></pre>
  
  <p>This is what I write in js.</p>
  
  <p>I use webpack2 and react^15.6.1.
  It can show vedio's controls but can not find local vedio.</p>
