title: How to crop the video via the surfaceview/surfaceholder class?
body: <p>Here is my question: how to crop the video via the surfaceview/surfaceholder class?</p>
  
  <p>In my survey, the only way to crop the video is to use the TextureView::setTransform/setLayoutParams,  am I right?</p>
  
  <p>But there is only one interface working with surfaceholder class in my 3rd-party video player library: VideoPlayer::setDisplay( SurfaceHolder holder ). If I don't use the TextureView class, is it possible to resolve this problem?</p>
  
  <p>I look forward to every possible suggestions,  thanks a lot!</p>
