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.
