title: FFMPEG and HTTPS
body: <p>ffmpeg lists http as a protocol when I ask: ffmpeg -protocols</p>
  
  <p>Does this also mean support for a https url? Do I need to encode this url somehow for the command line. I get "No such file or directory", but with http urls (at least some) it does work.</p>
  
  <p>A url (created for a Amazon S3 bucket) similar to this one does not seem to work:
  <a href="https://mycompany-video-test.s3.amazonaws.com/client/btr/video/xyz0011-x403-snap-n-go-ex/1/video/baby-laugh-ripping-paper.mp4?AWSAccessKeyId=AVIAZL9J6SIRPAA&amp;Expires=1323709667&amp;Signature=pTvS9F2do2t8%3D" rel="nofollow">https://mycompany-video-test.s3.amazonaws.com/client/btr/video/xyz0011-x403-snap-n-go-ex/1/video/baby-laugh-ripping-paper.mp4?AWSAccessKeyId=AVIAZL9J6SIRPAA&amp;Expires=1323709667&amp;Signature=pTvS9F2do2t8%3D</a></p>
  
  <p>I suspect the format of the url is problematic, I've also tried enclosing in quotes... Yes, this URL does not currently work as it has expired, but even while its valid, its a problem.</p>
  
  <p>In short:
  1) Should https work?
  2) Do I need to format the url somehow?</p>
