title: Using FFMPEG: How to do a Scene Change Detection? with timecode?
body: <p>Based on this article it seems that it is possible to use FFMPEG to detect scene change in videos:

  <p>Now I have a video that displays a book text and when the text (word or sentence) is spoken it gets highlighted. 
  Something like this audio book: <a href="https://youtu.be/lA7L6ZNVKjc">https://youtu.be/lA7L6ZNVKjc</a></p>
  
  <p>I need to know the timestamp when the text gets highlighted (hence scene change), this will allow me to add timestamp tags on my youtube video, so it becomes easier for listeners to navigate through the audiobook.</p>
  
  <p>What is the <em>magic</em> command line that would do this?</p>
  
  <p>Thank you very much!</p>
