"""Information Extractor class.
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 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.
+
+ Additionally, it must contain either a formats entry or a url one:
+
+ formats: A list of dictionaries for each format available, ordered
+ from worst to best quality.
+
+ Potential fields:
+ * url Mandatory. The URL of the video file
+ * ext Will be calculated from url if missing
+ * format A human-readable description of the format
+ ("mp4 container with h264/opus").
+ Calculated from the format_id, width, height.
+ and format_note fields if missing.
+ * format_id A short description of the format
+ ("mp4_h264_opus" or "19").
+ Technically optional, but strongly recommended.
+ * format_note Additional info about the format
+ ("3D" or "DASH video")
+ * width Width of the video, if known
+ * height Height of the video, if known
+ * resolution Textual description of width and height
+ * tbr Average bitrate of audio and video in KBit/s
+ * abr Average audio bitrate in KBit/s
+ * acodec Name of the audio codec in use
+ * asr Audio sampling rate in Hertz
+ * vbr Average video bitrate in KBit/s
+ * fps Frame rate
+ * vcodec Name of the video codec in use
+ * container Name of the container format
+ * 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", "m3u8" or so.
+ * 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.
+ * language_preference Is this in the correct requested
+ language?
+ 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_referer HTTP Referer header value to set.
+ * http_method HTTP method to use for the download.
+ * http_headers A dictionary of additional HTTP headers
+ to add to the request.
+ * http_post_data Additional data to send with a POST
+ request.
+ url: Final video URL.
ext: Video filename extension.
+ format: The video format, defaults to ext (used for --get-format)
+ player_url: SWF Player URL (used for rtmpdump).
The following fields are optional:
- format: The video format, defaults to ext (used for --get-format)
- thumbnails: A list of dictionaries (with the entries "resolution" and
- "url") for the varying thumbnails
+ display_id An alternative identifier for the video, not necessarily
+ unique, but available before title. Typically, id is
+ something like "4234987", title "Dancing naked mole rats",
+ and display_id "dancing-naked-mole-rats"
+ thumbnails: A list of dictionaries, with the following entries:
+ * "url"
+ * "width" (optional, int)
+ * "height" (optional, int)
+ * "resolution" (optional, string "{width}x{height"},
+ deprecated)
thumbnail: Full URL to a video thumbnail image.
description: One-line video description.
uploader: Full name of the video uploader.
+ timestamp: UNIX timestamp of the moment the video became available.
upload_date: Video upload date (YYYYMMDD).
+ If not explicitly set, calculated from timestamp.
uploader_id: Nickname or id of the video uploader.
- location: Physical location of the video.
- player_url: SWF Player URL (used for rtmpdump).
+ location: Physical location where the video was filmed.
subtitles: The subtitle file contents as a dictionary in the format
{language: subtitles}.
+ duration: Length of the video in seconds, as an integer.
view_count: How many users have watched the video on the platform.
- urlhandle: [internal] The urlHandle to be used to download the file,
- like returned by urllib.request.urlopen
+ like_count: Number of positive ratings of the video
+ dislike_count: Number of negative ratings of the video
+ comment_count: Number of comments on the video
+ age_limit: Age restriction for the video, as an integer (years)
+ webpage_url: The url to the video webpage, if given to youtube-dl it
+ should allow to get the same result again. (It will be set
+ by YoutubeDL if it's missing)
+ categories: A list of categories that the video falls in, for example
+ ["Sports", "Berlin"]
+ is_live: True, False, or None (=unknown). Whether this video is a
+ live stream that goes on instead of a fixed-length video.
+
+ 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 or a PagedList object, each
+ element of which is a valid dictionary under this specfication.
+
+ Additionally, playlists can have "title" 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.
+
+ Additionally, it may have properties believed to be identical to the
+ resolved entity, 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.
