"""Information Extractor class.

|

Information extractors are the classes that, given a URL, extract
|
||||
information from the video (or videos) the URL refers to. This
|
||||
information includes the real video URL, the video title and simplified
|
||||
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:

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

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

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.
|
||||
uploader: Nickname of the video uploader.
|

title: Literal title.
|

uploader: Nickname of the video uploader, unescaped.
|
||||
upload_date: Video upload date (YYYYMMDD).
|

title: Video title, unescaped.
|
||||
ext: Video filename extension.
|
||||
format: Video format.
|
||||
player_url: SWF Player URL (may be None).
|
||||
|
||||
The following fields are optional. Their primary purpose is to allow
|
||||
youtube-dl to serve as the backend for a video search function, such
|
||||
as the one in youtube2mp3. They are only used when their respective
|
||||
forced printing functions are called:
|
||||
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.
|
||||
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 urllib2.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.

described above.
