title: How can I get direct video url from YouTube video URL?
body: <p>I'm going to play YouTube and Vimeo videos using React-Native.
  For now I implemented <a href="https://github.com/react-native-community/react-native-video" rel="noreferrer">React-Native-Video</a> and it does not support to play YouTube or Vimeo urls while can play direct video urls.
  So I just want to get a direct reference to a file (or a stream?) from YouTube Video URL.
      e.g from </p>
  
  <pre><code>https://www.youtube.com/watch?v=PCwL3-hkKrg
  </code></pre>
  
  <p>Is there any good third party services or websites to solve this problem?
  No matter what types of code or ways you will use though I'm using React-Native to play YouTube videos currently.</p>
