Youtube Playlist Content Type for FeinCMS
To use this content type, you need the Gdata Python Client Library. Download it here: http://code.google.com/p/gdata-python-client/downloads/list
Make a symlink to src/gdata and src/atom
Check out http://googlesystem.blogspot.com/2008/01/youtube-feeds.html for how to get the URL of the feeds.
Add your Youtube developer key to the settings file::
YOUTUBE_DEV_KEY = "XXXX...........XXXX"
YOUTUBE_CLIENT_ID = "any_string"Youtube feeds are paginated after 25 objects. Since the content type doesn't support pagination yet you are basically limited to 25 videos per feed.
