  30
  31         Information extractors are the classes that, given a URL, extract
  32         information from the video (or videos) the URL refers to. This
  33         information includes the real video URL, the video title and simplified
  34         title, author and others. The information is stored in a dictionary
  35         which is then passed to the FileDownloader. The FileDownloader
  36         processes this information possibly downloading the video to the file
  37         system, among other possible outcomes. The dictionaries must include
  38         the following fields:
  39
  40         id:             Video identifier.
  41         url:            Final video URL.
  42         uploader:       Nickname of the video uploader.
  43         title:          Literal title.
  44         ext:            Video filename extension.
  45         format:         Video format.
  46         player_url:     SWF Player URL (may be None).
  47
  48         The following fields are optional. Their primary purpose is to allow
  49         youtube-dl to serve as the backend for a video search function, such
  50         as the one in youtube2mp3.  They are only used when their respective
  51         forced printing functions are called:
  52
  53         thumbnail:      Full URL to a video thumbnail image.
  54         description:    One-line video description.
  55
  56         Subclasses of this one should re-define the _real_initialize() and
  57         _real_extract() methods and define a _VALID_URL regexp.
  58         Probably, they should also be added to the list of extractors.
