"""Information Extractor class.
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
+ passed to the YoutubeDL. The YoutubeDL processes this
information possibly downloading the video to the file system, among
other possible outcomes.
- The dictionaries must include the following fields:
+ The type field determines the type of the result.
+ By far the most common value (and the default if _type is missing) is
+ "video", which indicates a single video.
+
+ For a video, the dictionaries must include the following fields:
id: Video identifier.
- url: Final video URL.
title: Video title, unescaped.

+ and format_note fields if missing.
+ * format_id A short description of the format
+ ("mp4_h264_opus" or "19").

+ * filesize The number of bytes, if known in advance
+ * filesize_approx An estimate for the number of bytes
+ * player_url SWF Player URL (used for rtmpdump).
+ * protocol The protocol that will be used for the actual
+ download, lower-case.
+ "http", "https", "rtsp", "rtmp", "rtmpe",
+ "m3u8", "m3u8_native" or "http_dash_segments".
+ * preference Order number of this format. If this field is
+ present and not None, the formats get sorted
+ by this field, regardless of all other values.
+ -1 for default (order by other properties),
+ -2 or smaller for less than default.
+ < -1000 to hide the format (if there is
+ another one which is strictly better)
+ * language Language code, e.g. "de" or "en-US".
+ * language_preference Is this in the language mentioned in
+ the URL?
+ 10 if it's what the URL is about,
+ -1 for default (don't know),
+ -10 otherwise, other values reserved for now.
+ * quality Order number of the video quality of this
+ format, irrespective of the file format.
+ -1 for default (order by other properties),
+ -2 or smaller for less than default.
+ * source_preference Order number for this video source
+ (quality takes higher priority)
+ -1 for default (order by other properties),
+ -2 or smaller for less than default.
+ * http_headers A dictionary of additional HTTP headers
+ to add to the request.
+ * stretched_ratio If given and not 1, indicates that the
+ video's pixels are not square.
+ width : height ratio as float.
+ * no_resume The server does not support resuming the
+ (HTTP or RTMP) download. Boolean.

+ * "data": The subtitles file contents
+ * "url": A URL pointing to the subtitles file
+ "ext" will be calculated from URL if missing
+ automatic_captions: Like 'subtitles', used by the YoutubeIE for
+ automatically generated captions
+ duration: Length of the video in seconds, as an integer or float.
view_count: How many users have watched the video on the platform.

+ tags: A list of tags assigned to the video, e.g. ["sweden", "pop music"]
+ is_live: True, False, or None (=unknown). Whether this video is a
+ live stream that goes on instead of a fixed-length video.
+ start_time: Time in seconds where the reproduction should start, as
+ specified in the URL.
+ end_time: Time in seconds where the reproduction should end, as
+ specified in the URL.
+
+ The following fields should only be used when the video belongs to some logical
+ chapter or section:
+
+ chapter: Name or title of the chapter the video belongs to.
+ chapter_number: Number of the chapter the video belongs to, as an integer.
+ chapter_id: Id of the chapter the video belongs to, as a unicode string.

+ season_number: Number of the season the video episode belongs to, as an integer.

+ without any kind of decoration.
+ episode_number: Number of the video episode within a season, as an integer.
+ episode_id: Id of the video episode, as a unicode string.
+
+ The following fields should only be used when the media is a track or a part of
+ a music album:
+
+ track: Title of the track.
+ track_number: Number of the track within an album or a disc, as an integer.
+ track_id: Id of the track (useful in case of custom indexing, e.g. 6.iii),
+ as a unicode string.
+ artist: Artist(s) of the track.
+ genre: Genre(s) of the track.
+ album: Title of the album the track belongs to.
+ album_type: Type of the album (e.g. "Demo", "Full-length", "Split", "Compilation", etc).
+ album_artist: List of all artists appeared on the album (e.g.
+ "Ash Borer / Fell Voices" or "Various Artists", useful for splits
+ and compilations).
+ disc_number: Number of the disc or other physical medium the track belongs to,
+ as an integer.
+ release_year: Year (YYYY) when the album was released.
+
+ Unless mentioned otherwise, the fields should be Unicode strings.
+
+ Unless mentioned otherwise, None is equivalent to absence of information.
+
+
+ _type "playlist" indicates multiple videos.
+ There must be a key "entries", which is a list, an iterable, or a PagedList
+ object, each element of which is a valid dictionary by this specification.
+
+ Additionally, playlists can have "title", "description" and "id" attributes
+ with the same semantics as videos (see above).
+
+
+ _type "multi_video" indicates that there are multiple videos that
+ form a single show, for examples multiple acts of an opera or TV episode.
+ It must have an entries key like a playlist and contain all the keys
+ required for a video at the same time.
+
+
+ _type "url" indicates that the video must be extracted from another
+ location, possibly by a different extractor. Its only required key is:
+ "url" - the next URL to extract.
+ The key "ie_key" can be set to the class name (minus the trailing "IE",
+ e.g. "Youtube") if the extractor class is known in advance.
+ Additionally, the dictionary may have any properties of the resolved entity
+ known in advance, for example "title" if the title of the referred video is
+ known ahead of time.
+
+
+ _type "url_transparent" entities have the same specification as "url", but
+ indicate that the given additional information is more precise than the one
+ associated with the resolved URL.
+ This is useful when a site employs a video service that hosts the video and
+ its technical metadata, but that video service does not embed a useful
+ title, description etc.
- 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.
