  <p>I am looking for a library or open source project that provides UI for trimming videos as you see in the screenshot. Including</p>
  
  <ul>
  <li>Range selector with ability to increase, decrease and move the selection</li>
  <li>Thumbnails</li>
  <li>Current position of playback</li>
  </ul>
  
  <p>Just the UI not the trimming itself.</p>
  
  <p>If there is no ready solution available, then I'd like to now how to combine existing UI elements in a smart manner to achieve this or something similiar.</p>
  
  <p><strong>Here is what I finally implemented:</strong> <a href="https://stackoverflow.com/questions/36598606/range-selector-range-seekbar-to-trim-video-including-thumbnails/48783823#comment63164349_36785834">Range selector / range seekbar to trim video including thumbnails</a></p>
