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

    information about the video (or videos) the URL refers to. This 

    information includes the real video URL, the video title, author and 

    others. The information is stored in a dictionary which is then 

    passed to the FileDownloader. The FileDownloader processes this 

    information possibly downloading the video to the file system, among 

    other possible outcomes. 

 

    The dictionaries must include the following fields: 

 

    id:             Video identifier. 

    url:            Final video URL. 

    title:          Video title, unescaped. 

    ext:            Video filename extension. 

    uploader:       Full name of the video uploader. 

    upload_date:    Video upload date (YYYYMMDD). 

 

    The following fields are optional: 

 

    format:         The video format, defaults to ext (used for --get-format) 

    thumbnail:      Full URL to a video thumbnail image. 

    description:    One-line video description. 

    uploader_id:    Nickname or id of the video uploader. 

    player_url:     SWF Player URL (used for rtmpdump). 

    subtitles:      The .srt file contents. 

    urlhandle:      [internal] The urlHandle to be used to download the file, 

                    like returned by urllib.request.urlopen 

 

    The fields should all be Unicode strings. 

 

    Subclasses of this one should re-define the _real_initialize() and 

    _real_extract() methods and define a _VALID_URL regexp. 

    Probably, they should also be added to the list of extractors. 

 

    _real_extract() must return a *list* of information dictionaries as 

    described above. 

 

    Finally, the _WORKING attribute should be set to False for broken IEs 

    in order to warn the users and skip the tests.
