title: ffmpeg- drawtext above specified coordinates
body: <p>Is it possible to draw a text above the specified coordinates? Example i want to write "Hello" at coordinate (100,100). By default ffmpeg draws the text in top to bottom manner, i.e , Starting point would be 100,100 and will draw downwards.
  Can it be drawn in a bottom up manner? (Start upwards from 100,100).
  Thanks</p>
