"""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:
-
- id: Video identifier.
- url: Final video URL.
- uploader: Nickname of the video uploader.
- title: Literal title.
- 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:
-
- thumbnail: Full URL to a video thumbnail image.
- description: One-line video description.
+ 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.
+ uploader: Nickname of the video uploader, unescaped.
+ upload_date: Video upload date (YYYYMMDD).
+ 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.
+ 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.
+
+ _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.
