- """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.
- 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.
