alt_title: A secondary title of the video.
display_id An alternative identifier for the video, not necessarily
unique, but available before title. Typically, id is
* "url": A URL pointing to the subtitles file
It can optionally also have:
* "name": Name or description of the subtitles
- * http_headers: A dictionary of additional HTTP headers
+ * "http_headers": A dictionary of additional HTTP headers
to add to the request.
"ext" will be calculated from URL if missing
automatic_captions: Like 'subtitles'; contains automatically generated
title, description etc.
- Subclasses of this one should re-define the _real_initialize() and
- _real_extract() methods and define a _VALID_URL regexp.
+ Subclasses of this should define a _VALID_URL regexp and, re-define the

Probably, they should also be added to the list of extractors.
Subclasses may also override suitable() if necessary, but ensure the function
