title: How to extract frames(or a perticular frame) from a YUV video using ffmpeg
body: <p>Here is the code for extracting frames from a <code>MP4</code> video. 
  <code>ffmpeg -i above_marathon_250.mp4 images%03d.bmp</code> 
  But the same code does not work for <code>YUV</code> format video.
  Does anyone knows how it is possible to extract frame(s) from <code>YUV</code>format video?</p>
