title: How does youtube downloader works?
body: <p>There are many similar questions like this but there is no really a working answer but there are some API present for that. But there is no clear answer about how it is done( like how to find the link of the video file and download it). Most of the questions are for C# in the website.</p>
  
  <p>So,can anyone explain how it is done so that it can be implemented in any language.</p>
  
  <p>I found this <a href="https://stackoverflow.com/questions/3172962/how-does-a-youtube-movie-downloader-work-youtube">answer</a> but I cant do it properly.</p>
  
  <p>Thank you!</p>
