title: python: get all youtube video urls of a channel
body: <p>I want to get all video url's of a specific channel. I think json with python or java would be a good choice. I can get the newest video with the following code, but how can I get ALL video links (>500)?</p>
  
  <pre><code>import urllib, json
  author = 'Youtube_Username'
  inp = urllib.urlopen(r'http://gdata.youtube.com/feeds/api/videos?max-results=1&amp;alt=json&amp;orderby=published&amp;author=' + author)
  resp = json.load(inp)
  inp.close()
  first = resp['feed']['entry'][0]
  print first['title'] # video title
  print first['link'][0]['href'] #url
  </code></pre>
