Fetches FLV URL from "sdURL" in addVariable("sequence") JSON,
instead of addVariable("video") which doesnot exist today.
Supports new title, uploader nickname format.
This, in particular, lets me grab the videos from the beginners channel with
URLs like:
http://vimeo.com/groups/fivebyfive/videos/22648611
Note that the regexp *will* break for other URLs that we don't know about
and that's on purpose: we don't want to accidentally grab videos that would
be passed on to other information extractors.
This IE should be full-featured.
Public videos can be downloaded without login, e.g:
https://www.facebook.com/video/video.php?v=696729990595
Private videos need login, and subject to login rate limit of
a couple of tries / minute.
The "playlist_prefix" parameter was missing when parsing playlist urls
that match the recently added format, e.g.:
http://www.youtube.com/user/stanforduniversity#g/c/9D558D49CA734A02
For these URLs (basically, for every playlist type so far, except the
artist list) playlist_prefix has to be equal to "p" for correct
exctraction.
Artist playlist pages have different format compared to user playlists,
thus more format checking is needed to construct the correct URL.
From the artist playlist this method downloads all listed below the
"Videos by [Artist Name]" header, plus usually there's one more
video on the side, titled "Youtube Mix for [Artist Name]", which
has a link format that currently cannot be distinguished from the other
videos in the list.
