title: Can I mass-download YouTube videos?
body: <p>Been talking to Social Gnip, and looking at the Youtube Data API, but it looks like they just provide the the URL to the video.</p>
  
  <p>Can I use something like youtube-dl to download all those videos? NOT store them, just analyze them and discard them.</p>
  
  <p>Starting a computer vision project, and want to analyze YouTube videos to find products to identify influencers.</p>
