50 """Information Extractor class.
52 Information extractors are the classes that, given a URL, extract
53 information about the video (or videos) the URL refers to. This
54 information includes the real video URL, the video title, author and
55 others. The information is stored in a dictionary which is then
56 passed to the YoutubeDL. The YoutubeDL processes this
57 information possibly downloading the video to the file system, among
58 other possible outcomes.
60 The type field determines the type of the result.
61 By far the most common value (and the default if _type is missing) is
62 "video", which indicates a single video.
64 For a video, the dictionaries must include the following fields:
67 title: Video title, unescaped.
69 Additionally, it must contain either a formats entry or a url one:
71 formats: A list of dictionaries for each format available, ordered
72 from worst to best quality.
75 * url Mandatory. The URL of the video file
76 * ext Will be calculated from URL if missing
77 * format A human-readable description of the format
78 ("mp4 container with h264/opus").
79 Calculated from the format_id, width, height.
80 and format_note fields if missing.
81 * format_id A short description of the format
82 ("mp4_h264_opus" or "19").
83 Technically optional, but strongly recommended.
84 * format_note Additional info about the format
85 ("3D" or "DASH video")
86 * width Width of the video, if known
87 * height Height of the video, if known
88 * resolution Textual description of width and height
89 * tbr Average bitrate of audio and video in KBit/s
90 * abr Average audio bitrate in KBit/s
91 * acodec Name of the audio codec in use
92 * asr Audio sampling rate in Hertz
93 * vbr Average video bitrate in KBit/s
95 * vcodec Name of the video codec in use
96 * container Name of the container format
97 * filesize The number of bytes, if known in advance
98 * filesize_approx An estimate for the number of bytes
99 * player_url SWF Player URL (used for rtmpdump).
100 * protocol The protocol that will be used for the actual
101 download, lower-case.
102 "http", "https", "rtsp", "rtmp", "rtmpe",
103 "m3u8", or "m3u8_native".
104 * preference Order number of this format. If this field is
105 present and not None, the formats get sorted
106 by this field, regardless of all other values.
107 -1 for default (order by other properties),
108 -2 or smaller for less than default.
109 < -1000 to hide the format (if there is
110 another one which is strictly better)
111 * language_preference Is this in the correct requested
113 10 if it's what the URL is about,
114 -1 for default (don't know),
115 -10 otherwise, other values reserved for now.
116 * quality Order number of the video quality of this
117 format, irrespective of the file format.
118 -1 for default (order by other properties),
119 -2 or smaller for less than default.
120 * source_preference Order number for this video source
121 (quality takes higher priority)
122 -1 for default (order by other properties),
123 -2 or smaller for less than default.
124 * http_headers A dictionary of additional HTTP headers
125 to add to the request.
126 * stretched_ratio If given and not 1, indicates that the
127 video's pixels are not square.
128 width : height ratio as float.
129 * no_resume The server does not support resuming the
130 (HTTP or RTMP) download. Boolean.
132 url: Final video URL.
133 ext: Video filename extension.
134 format: The video format, defaults to ext (used for --get-format)
135 player_url: SWF Player URL (used for rtmpdump).
137 The following fields are optional:
139 alt_title: A secondary title of the video.
140 display_id An alternative identifier for the video, not necessarily
141 unique, but available before title. Typically, id is
142 something like "4234987", title "Dancing naked mole rats",
143 and display_id "dancing-naked-mole-rats"
144 thumbnails: A list of dictionaries, with the following entries:
145 * "id" (optional, string) - Thumbnail format ID
147 * "preference" (optional, int) - quality of the image
148 * "width" (optional, int)
149 * "height" (optional, int)
150 * "resolution" (optional, string "{width}x{height"},
152 thumbnail: Full URL to a video thumbnail image.
153 description: Full video description.
154 uploader: Full name of the video uploader.
155 creator: The main artist who created the video.
156 release_date: The date (YYYYMMDD) when the video was released.
157 timestamp: UNIX timestamp of the moment the video became available.
158 upload_date: Video upload date (YYYYMMDD).
159 If not explicitly set, calculated from timestamp.
160 uploader_id: Nickname or id of the video uploader.
161 location: Physical location where the video was filmed.
162 subtitles: The available subtitles as a dictionary in the format
163 {language: subformats}. "subformats" is a list sorted from
164 lower to higher preference, each element is a dictionary
165 with the "ext" entry and one of:
166 * "data": The subtitles file contents
167 * "url": A URL pointing to the subtitles file
168 "ext" will be calculated from URL if missing
169 automatic_captions: Like 'subtitles', used by the YoutubeIE for
170 automatically generated captions
171 duration: Length of the video in seconds, as an integer or float.
172 view_count: How many users have watched the video on the platform.
173 like_count: Number of positive ratings of the video
174 dislike_count: Number of negative ratings of the video
175 repost_count: Number of reposts of the video
176 average_rating: Average rating give by users, the scale used depends on the webpage
177 comment_count: Number of comments on the video
178 comments: A list of comments, each with one or more of the following
179 properties (all but one of text or html optional):
180 * "author" - human-readable name of the comment author
181 * "author_id" - user ID of the comment author
183 * "html" - Comment as HTML
184 * "text" - Plain text of the comment
185 * "timestamp" - UNIX timestamp of comment
186 * "parent" - ID of the comment this one is replying to.
187 Set to "root" to indicate that this is a
188 comment to the original video.
189 age_limit: Age restriction for the video, as an integer (years)
190 webpage_url: The URL to the video webpage, if given to youtube-dl it
191 should allow to get the same result again. (It will be set
192 by YoutubeDL if it's missing)
193 categories: A list of categories that the video falls in, for example
195 tags: A list of tags assigned to the video, e.g. ["sweden", "pop music"]
196 is_live: True, False, or None (=unknown). Whether this video is a
197 live stream that goes on instead of a fixed-length video.
198 start_time: Time in seconds where the reproduction should start, as
199 specified in the URL.
200 end_time: Time in seconds where the reproduction should end, as
201 specified in the URL.
203 Unless mentioned otherwise, the fields should be Unicode strings.
205 Unless mentioned otherwise, None is equivalent to absence of information.
208 _type "playlist" indicates multiple videos.
209 There must be a key "entries", which is a list, an iterable, or a PagedList
210 object, each element of which is a valid dictionary by this specification.
212 Additionally, playlists can have "title", "description" and "id" attributes
213 with the same semantics as videos (see above).
216 _type "multi_video" indicates that there are multiple videos that
217 form a single show, for examples multiple acts of an opera or TV episode.
218 It must have an entries key like a playlist and contain all the keys
219 required for a video at the same time.
222 _type "url" indicates that the video must be extracted from another
223 location, possibly by a different extractor. Its only required key is:
224 "url" - the next URL to extract.
225 The key "ie_key" can be set to the class name (minus the trailing "IE",
226 e.g. "Youtube") if the extractor class is known in advance.
227 Additionally, the dictionary may have any properties of the resolved entity
228 known in advance, for example "title" if the title of the referred video is
232 _type "url_transparent" entities have the same specification as "url", but
233 indicate that the given additional information is more precise than the one
234 associated with the resolved URL.
235 This is useful when a site employs a video service that hosts the video and
236 its technical metadata, but that video service does not embed a useful
237 title, description etc.
240 Subclasses of this one should re-define the _real_initialize() and
241 _real_extract() methods and define a _VALID_URL regexp.
242 Probably, they should also be added to the list of extractors.
244 Finally, the _WORKING attribute should be set to False for broken IEs
245 in order to warn the users and skip the tests.
