title: How to draw points on video and save using opencv cv2 python
body: <p>I have an input file with the frame number and x,y coordinates for every frame in a video. Ex: </p>
  
  <pre><code>&lt;frame#&gt; &lt;x&gt;,&lt;y&gt;
   3984    346,983
  </code></pre>
  
  <p>How would I use this information to draw these points on the respective frames and save the video with this information? </p>
