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.
- ext: Video filename extension.
- Instead of url and ext, formats can also specified.
+ 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

+ ("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").

+ "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.
+

- thumbnails: A list of dictionaries (with the entries "resolution" and
- "url") for the varying thumbnails
+ alt_title: A secondary title of the video.

+ 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

+ * "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_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 as a dictionary in the format
- {language: subtitles}.
+ 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.
- 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
+ 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)
- formats: A list of dictionaries for each format available, it must
- be 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")
- * 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
- * abr Average audio bitrate in KBit/s
- * acodec Name of the audio codec in use
- * vbr Average video bitrate in KBit/s
- * vcodec Name of the video codec in use
- * filesize The number of bytes, if known in advance
- webpage_url: The url to the video webpage, if given to youtube-dl it
+ 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.
+
+
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.
