  27     """Information Extractor class.
  28
  29     Information extractors are the classes that, given a URL, extract
  30     information about the video (or videos) the URL refers to. This
  31     information includes the real video URL, the video title, author and
  32     others. The information is stored in a dictionary which is then
  33     passed to the FileDownloader. The FileDownloader processes this
  34     information possibly downloading the video to the file system, among
  35     other possible outcomes.
  36
  37     The dictionaries must include the following fields:
  38
  39     id:             Video identifier.
  40     url:            Final video URL.
  41     title:          Video title, unescaped.
  42     ext:            Video filename extension.
  43
  44     The following fields are optional:
  45
  46     format:         The video format, defaults to ext (used for --get-format)
  47     thumbnail:      Full URL to a video thumbnail image.
  48     description:    One-line video description.
  49     uploader:       Full name of the video uploader.
  50     upload_date:    Video upload date (YYYYMMDD).
  51     uploader_id:    Nickname or id of the video uploader.
  52     location:       Physical location of the video.
  53     player_url:     SWF Player URL (used for rtmpdump).
  54     subtitles:      The subtitle file contents.
  55     urlhandle:      [internal] The urlHandle to be used to download the file,
  56                     like returned by urllib.request.urlopen
  57
  58     The fields should all be Unicode strings.
  59
  60     Subclasses of this one should re-define the _real_initialize() and
  61     _real_extract() methods and define a _VALID_URL regexp.
  62     Probably, they should also be added to the list of extractors.
  63
  64     _real_extract() must return a *list* of information dictionaries as
  65     described above.
  66
  67     Finally, the _WORKING attribute should be set to False for broken IEs
  68     in order to warn the users and skip the tests.
