"""Information Extractor class.
|
||||
|
||||
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.
|
||||
|
||||
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: Full name of the video uploader.
|
||||
upload_date: Video upload date (YYYYMMDD).
|
||||
uploader_id: Nickname or id of the video uploader.
|
||||
location: Physical location of the video.
|
||||
player_url: SWF Player URL (used for rtmpdump).
|
||||
subtitles: The subtitle 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.
