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.
