   frame = [];
    end

  Although this method can be more convenient than calling NEXT and GETFRAME
  separately, there is no way to distinguish between a zero-sized frame and
  reading past the end of the stream.  

  Typical usage:
    vr = videoReader('numbers.uncompressed.avi');
    info = getinfo(vr);
    for i=1:info.numFrames
      img = getnext(vr);
      imshow(img);
      pause(1/info.fps);
    end
    vr = close(vr);
