  21     """Information Extractor class.
  22
  23     Information extractors are the classes that, given a URL, extract
  24     information about the video (or videos) the URL refers to. This
  25     information includes the real video URL, the video title, author and
  26     others. The information is stored in a dictionary which is then
  27     passed to the FileDownloader. The FileDownloader processes this
  28     information possibly downloading the video to the file system, among
  29     other possible outcomes.
  30
  31     The dictionaries must include the following fields:
  32
  33     id:             Video identifier.
  34     url:            Final video URL.
  35     uploader:       Nickname of the video uploader, unescaped.
  36     upload_date:    Video upload date (YYYYMMDD).
  37     title:          Video title, unescaped.
  38     ext:            Video filename extension.
  39
  40     The following fields are optional:
  41
  42     format:         The video format, defaults to ext (used for --get-format)
  43     thumbnail:      Full URL to a video thumbnail image.
  44     description:    One-line video description.
  45     player_url:     SWF Player URL (used for rtmpdump).
  46     subtitles:      The .srt file contents.
  47     urlhandle:      [internal] The urlHandle to be used to download the file,
  48                     like returned by urllib.request.urlopen
  49
  50     The fields should all be Unicode strings.
  51
  52     Subclasses of this one should re-define the _real_initialize() and
  53     _real_extract() methods and define a _VALID_URL regexp.
  54     Probably, they should also be added to the list of extractors.
  55
  56     _real_extract() must return a *list* of information dictionaries as
  57     described above.
  58
  59     Finally, the _WORKING attribute should be set to False for broken IEs
  60     in order to warn the users and skip the tests.
