"""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.
+
+ 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", "rtmpe",
+ "m3u8", or "m3u8_native".
+ * 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_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_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.
+
+ 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)
+ alt_title: A secondary title of the video.
+ 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:
+ * "id" (optional, string) - Thumbnail format ID
+ * "url"
+ * "preference" (optional, int) - quality of the image
+ * "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.
+ description: Full video description.
uploader: Full name of the video uploader.
+ creator: The main artist who created the video.
+ release_date: The date (YYYYMMDD) when the video was released.
+ 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).
- subtitles: The subtitle file contents.
- urlhandle: [internal] The urlHandle to be used to download the file,
- like returned by urllib.request.urlopen
+ location: Physical location where the video was filmed.
+ subtitles: The available subtitles as a dictionary in the format
+ {language: subformats}. "subformats" is a list sorted from
+ lower to higher preference, each element is a dictionary
+ with the "ext" entry and one of:
+ * "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.
+ view_count: How many users have watched the video on the platform.
+ like_count: Number of positive ratings of the video
+ dislike_count: Number of negative ratings of the video
+ repost_count: Number of reposts of the video
+ average_rating: Average rating give by users, the scale used depends on the webpage
+ comment_count: Number of comments on the video
+ comments: A list of comments, each with one or more of the following
+ properties (all but one of text or html optional):
+ * "author" - human-readable name of the comment author
+ * "author_id" - user ID of the comment author
+ * "id" - Comment ID
+ * "html" - Comment as HTML
+ * "text" - Plain text of the comment
+ * "timestamp" - UNIX timestamp of comment
+ * "parent" - ID of the comment this one is replying to.
+ Set to "root" to indicate that this is a
+ comment to the original 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"]
+ 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.
+
+ 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.
