title: Use ELCImagePickerController to pick video
body: <p>I am trying to pick video by <code>ELCImagePickerController</code> from photo library, but when I print this</p>
  
  <pre><code>NSLog(@"%@",[dict valueForKey:@"UIImagePickerControllerMediaType"]);
  </code></pre>
  
  <p>it returns <code>ALAssetTypeVideo</code> , not a <strong>public.movie</strong> type,</p>
  
  <p>I have no idea is there any way to pick a movie(like .mov) from <code>ALAssetTypeVideo</code> ?</p>
  
  <p>sorry , My English is not very good :')</p>
