title: Combining two ffmpeg commands into single command
body: <p>I want to combine two ffmpeg commands to single ffmpeg command.</p>
  
  <pre><code>exec("ffmpeg -i mimic/api/video/1560754087943.mp4 -i logo.png -filter_complex"." overlay=20:20"." topleft.mp4");
  
  
  
  exec('ffmpeg -i topleft.mp4 -vf drawtext="fontfile=ARIBLK.ttf: text=sonukh3921: fontcolor=white: fontsize=20: x=20: y=65" output_video.mp4');
  </code></pre>
  
  <p>Is this possible to use the output from the first command for the second line, without using two separate commands?</p>
