        Information extractors are the classes that, given a URL, extract

-       uploader:       Nickname of the video uploader.

-       format:         Video format.
-       player_url:     SWF Player URL (may be None).

-       The following fields are optional. Their primary purpose is to allow
-       youtube-dl to serve as the backend for a video search function, such
