50 class InfoExtractor(object):
51 """Information Extractor class.
53 Information extractors are the classes that, given a URL, extract
54 information about the video (or videos) the URL refers to. This
55 information includes the real video URL, the video title, author and
56 others. The information is stored in a dictionary which is then
57 passed to the YoutubeDL. The YoutubeDL processes this
58 information possibly downloading the video to the file system, among
59 other possible outcomes.
61 The type field determines the type of the result.
62 By far the most common value (and the default if _type is missing) is
63 "video", which indicates a single video.
65 For a video, the dictionaries must include the following fields:
68 title: Video title, unescaped.
70 Additionally, it must contain either a formats entry or a url one:
72 formats: A list of dictionaries for each format available, ordered
73 from worst to best quality.
76 * url Mandatory. The URL of the video file
77 * ext Will be calculated from URL if missing
78 * format A human-readable description of the format
79 ("mp4 container with h264/opus").
80 Calculated from the format_id, width, height.
81 and format_note fields if missing.
82 * format_id A short description of the format
83 ("mp4_h264_opus" or "19").
84 Technically optional, but strongly recommended.
85 * format_note Additional info about the format
86 ("3D" or "DASH video")
87 * width Width of the video, if known
88 * height Height of the video, if known
89 * resolution Textual description of width and height
90 * tbr Average bitrate of audio and video in KBit/s
91 * abr Average audio bitrate in KBit/s
92 * acodec Name of the audio codec in use
93 * asr Audio sampling rate in Hertz
94 * vbr Average video bitrate in KBit/s
96 * vcodec Name of the video codec in use
97 * container Name of the container format
98 * filesize The number of bytes, if known in advance
99 * filesize_approx An estimate for the number of bytes
100 * player_url SWF Player URL (used for rtmpdump).
101 * protocol The protocol that will be used for the actual
102 download, lower-case.
103 "http", "https", "rtsp", "rtmp", "rtmpe",
104 "m3u8", or "m3u8_native".
105 * preference Order number of this format. If this field is
106 present and not None, the formats get sorted
107 by this field, regardless of all other values.
108 -1 for default (order by other properties),
109 -2 or smaller for less than default.
110 < -1000 to hide the format (if there is
111 another one which is strictly better)
112 * language Language code, e.g. "de" or "en-US".
113 * language_preference Is this in the language mentioned in
115 10 if it's what the URL is about,
116 -1 for default (don't know),
117 -10 otherwise, other values reserved for now.
118 * quality Order number of the video quality of this
119 format, irrespective of the file format.
120 -1 for default (order by other properties),
121 -2 or smaller for less than default.
122 * source_preference Order number for this video source
123 (quality takes higher priority)
124 -1 for default (order by other properties),
125 -2 or smaller for less than default.
126 * http_headers A dictionary of additional HTTP headers
127 to add to the request.
128 * stretched_ratio If given and not 1, indicates that the
129 video's pixels are not square.
130 width : height ratio as float.
131 * no_resume The server does not support resuming the
132 (HTTP or RTMP) download. Boolean.
134 url: Final video URL.
135 ext: Video filename extension.
136 format: The video format, defaults to ext (used for --get-format)
137 player_url: SWF Player URL (used for rtmpdump).
139 The following fields are optional:
141 alt_title: A secondary title of the video.
142 display_id An alternative identifier for the video, not necessarily
143 unique, but available before title. Typically, id is
144 something like "4234987", title "Dancing naked mole rats",
145 and display_id "dancing-naked-mole-rats"
146 thumbnails: A list of dictionaries, with the following entries:
147 * "id" (optional, string) - Thumbnail format ID
149 * "preference" (optional, int) - quality of the image
150 * "width" (optional, int)
151 * "height" (optional, int)
152 * "resolution" (optional, string "{width}x{height"},
154 thumbnail: Full URL to a video thumbnail image.
155 description: Full video description.
156 uploader: Full name of the video uploader.

158 release_date: The date (YYYYMMDD) when the video was released.
159 timestamp: UNIX timestamp of the moment the video became available.
160 upload_date: Video upload date (YYYYMMDD).
161 If not explicitly set, calculated from timestamp.
162 uploader_id: Nickname or id of the video uploader.
163 location: Physical location where the video was filmed.
164 subtitles: The available subtitles as a dictionary in the format
165 {language: subformats}. "subformats" is a list sorted from
166 lower to higher preference, each element is a dictionary
167 with the "ext" entry and one of:
168 * "data": The subtitles file contents
169 * "url": A URL pointing to the subtitles file
170 "ext" will be calculated from URL if missing
171 automatic_captions: Like 'subtitles', used by the YoutubeIE for
172 automatically generated captions
173 duration: Length of the video in seconds, as an integer or float.
174 view_count: How many users have watched the video on the platform.
175 like_count: Number of positive ratings of the video
176 dislike_count: Number of negative ratings of the video
177 repost_count: Number of reposts of the video
178 average_rating: Average rating give by users, the scale used depends on the webpage
179 comment_count: Number of comments on the video
180 comments: A list of comments, each with one or more of the following
181 properties (all but one of text or html optional):
182 * "author" - human-readable name of the comment author
183 * "author_id" - user ID of the comment author
185 * "html" - Comment as HTML
186 * "text" - Plain text of the comment
187 * "timestamp" - UNIX timestamp of comment
188 * "parent" - ID of the comment this one is replying to.
189 Set to "root" to indicate that this is a
190 comment to the original video.
191 age_limit: Age restriction for the video, as an integer (years)
192 webpage_url: The URL to the video webpage, if given to youtube-dl it
193 should allow to get the same result again. (It will be set
194 by YoutubeDL if it's missing)
195 categories: A list of categories that the video falls in, for example
197 tags: A list of tags assigned to the video, e.g. ["sweden", "pop music"]
198 is_live: True, False, or None (=unknown). Whether this video is a
199 live stream that goes on instead of a fixed-length video.
200 start_time: Time in seconds where the reproduction should start, as
201 specified in the URL.
202 end_time: Time in seconds where the reproduction should end, as

208 chapter: Name or title of the chapter the video belongs to.
209 chapter_number: Number of the chapter the video belongs to, as an integer.

216 season: Title of the season the video episode belongs to.
217 season_number: Number of the season the video episode belongs to, as an integer.
218 season_id: Id of the season the video episode belongs to, as a unicode string.
219 episode: Title of the video episode. Unlike mandatory video title field,
220 this field should denote the exact title of the video episode
221 without any kind of decoration.
222 episode_number: Number of the video episode within a season, as an integer.
223 episode_id: Id of the video episode, as a unicode string.
225 Unless mentioned otherwise, the fields should be Unicode strings.
227 Unless mentioned otherwise, None is equivalent to absence of information.
230 _type "playlist" indicates multiple videos.
231 There must be a key "entries", which is a list, an iterable, or a PagedList
232 object, each element of which is a valid dictionary by this specification.
234 Additionally, playlists can have "title", "description" and "id" attributes
235 with the same semantics as videos (see above).
238 _type "multi_video" indicates that there are multiple videos that
239 form a single show, for examples multiple acts of an opera or TV episode.
240 It must have an entries key like a playlist and contain all the keys
241 required for a video at the same time.
244 _type "url" indicates that the video must be extracted from another
245 location, possibly by a different extractor. Its only required key is:
246 "url" - the next URL to extract.
247 The key "ie_key" can be set to the class name (minus the trailing "IE",
248 e.g. "Youtube") if the extractor class is known in advance.
249 Additionally, the dictionary may have any properties of the resolved entity
250 known in advance, for example "title" if the title of the referred video is
254 _type "url_transparent" entities have the same specification as "url", but
255 indicate that the given additional information is more precise than the one
256 associated with the resolved URL.
257 This is useful when a site employs a video service that hosts the video and
258 its technical metadata, but that video service does not embed a useful
259 title, description etc.
262 Subclasses of this one should re-define the _real_initialize() and
263 _real_extract() methods and define a _VALID_URL regexp.
264 Probably, they should also be added to the list of extractors.
266 Finally, the _WORKING attribute should be set to False for broken IEs
267 in order to warn the users and skip the tests.
