title: Download video+audio in a single file from YouTube
body: <p>I tryed to download a video+audio from YouTube by using youtube-dl:</p>
  <pre><code>youtube-dl https://www.youtube.com/watch?v=7wfUUZvybPY
  </code></pre>
  <p>I got a video file (.webm) without audio. I'm looking for a way to download video+audio in a single file by using the command line (cmd) in Windows 10. Do you have any suggestion?</p>
