89 """Information Extractor class.
91 Information extractors are the classes that, given a URL, extract
92 information about the video (or videos) the URL refers to. This
93 information includes the real video URL, the video title, author and
94 others. The information is stored in a dictionary which is then
95 passed to the YoutubeDL. The YoutubeDL processes this
96 information possibly downloading the video to the file system, among
97 other possible outcomes.
99 The type field determines the type of the result.
100 By far the most common value (and the default if _type is missing) is
101 "video", which indicates a single video.
103 For a video, the dictionaries must include the following fields:
105 id: Video identifier.
106 title: Video title, unescaped.
108 Additionally, it must contain either a formats entry or a url one:
110 formats: A list of dictionaries for each format available, ordered
111 from worst to best quality.
114 * url The mandatory URL representing the media:
115 for plain file media - HTTP URL of this file,
117 for HLS - URL of the M3U8 media playlist,
118 for HDS - URL of the F4M manifest,
120 - HTTP URL to plain file media (in case of
122 - URL of the MPD manifest or base URL
123 representing the media if MPD manifest
124 is parsed from a string (in case of
126 for MSS - URL of the ISM manifest.
128 The URL of the manifest file in case of
130 for HLS - URL of the M3U8 master playlist,
131 for HDS - URL of the F4M manifest,
132 for DASH - URL of the MPD manifest,
133 for MSS - URL of the ISM manifest.
134 * ext Will be calculated from URL if missing
135 * format A human-readable description of the format
136 ("mp4 container with h264/opus").
137 Calculated from the format_id, width, height.
138 and format_note fields if missing.
139 * format_id A short description of the format
140 ("mp4_h264_opus" or "19").
141 Technically optional, but strongly recommended.
142 * format_note Additional info about the format
143 ("3D" or "DASH video")
144 * width Width of the video, if known
145 * height Height of the video, if known
146 * resolution Textual description of width and height
147 * tbr Average bitrate of audio and video in KBit/s
148 * abr Average audio bitrate in KBit/s
149 * acodec Name of the audio codec in use
150 * asr Audio sampling rate in Hertz
151 * vbr Average video bitrate in KBit/s
153 * vcodec Name of the video codec in use
154 * container Name of the container format
155 * filesize The number of bytes, if known in advance
156 * filesize_approx An estimate for the number of bytes

161 "m3u8", "m3u8_native" or "http_dash_segments".
163 Base URL for fragments. Each fragment's path
164 value (if present) will be relative to
166 * fragments A list of fragments of a fragmented media.
167 Each fragment entry must contain either an url
168 or a path. If an url is present it should be
169 considered by a client. Otherwise both path and
170 fragment_base_url must be present. Here is
171 the list of all potential fields:
172 * "url" - fragment's URL
173 * "path" - fragment's path relative to
175 * "duration" (optional, int or float)
176 * "filesize" (optional, int)
177 * preference Order number of this format. If this field is
178 present and not None, the formats get sorted
179 by this field, regardless of all other values.
180 -1 for default (order by other properties),
181 -2 or smaller for less than default.
182 < -1000 to hide the format (if there is
183 another one which is strictly better)
184 * language Language code, e.g. "de" or "en-US".
185 * language_preference Is this in the language mentioned in
187 10 if it's what the URL is about,

189 -10 otherwise, other values reserved for now.
190 * quality Order number of the video quality of this
191 format, irrespective of the file format.
192 -1 for default (order by other properties),
193 -2 or smaller for less than default.
194 * source_preference Order number for this video source
195 (quality takes higher priority)
196 -1 for default (order by other properties),
197 -2 or smaller for less than default.
198 * http_headers A dictionary of additional HTTP headers
199 to add to the request.
200 * stretched_ratio If given and not 1, indicates that the
201 video's pixels are not square.
202 width : height ratio as float.
203 * no_resume The server does not support resuming the
204 (HTTP or RTMP) download. Boolean.
205 * downloader_options A dictionary of downloader options as
206 described in FileDownloader

302 series: Title of the series or programme the video episode belongs to.
303 season: Title of the season the video episode belongs to.
304 season_number: Number of the season the video episode belongs to, as an integer.
305 season_id: Id of the season the video episode belongs to, as a unicode string.
306 episode: Title of the video episode. Unlike mandatory video title field,
307 this field should denote the exact title of the video episode
308 without any kind of decoration.
309 episode_number: Number of the video episode within a season, as an integer.
310 episode_id: Id of the video episode, as a unicode string.

324 "Ash Borer / Fell Voices" or "Various Artists", useful for splits
326 disc_number: Number of the disc or other physical medium the track belongs to,
328 release_year: Year (YYYY) when the album was released.
330 Unless mentioned otherwise, the fields should be Unicode strings.
332 Unless mentioned otherwise, None is equivalent to absence of information.
335 _type "playlist" indicates multiple videos.
336 There must be a key "entries", which is a list, an iterable, or a PagedList
337 object, each element of which is a valid dictionary by this specification.
339 Additionally, playlists can have "id", "title", "description", "uploader",
340 "uploader_id", "uploader_url", "duration" attributes with the same semantics
341 as videos (see above).
344 _type "multi_video" indicates that there are multiple videos that
345 form a single show, for examples multiple acts of an opera or TV episode.
346 It must have an entries key like a playlist and contain all the keys
347 required for a video at the same time.
350 _type "url" indicates that the video must be extracted from another
351 location, possibly by a different extractor. Its only required key is:
352 "url" - the next URL to extract.
353 The key "ie_key" can be set to the class name (minus the trailing "IE",
354 e.g. "Youtube") if the extractor class is known in advance.
355 Additionally, the dictionary may have any properties of the resolved entity
356 known in advance, for example "title" if the title of the referred video is
360 _type "url_transparent" entities have the same specification as "url", but
361 indicate that the given additional information is more precise than the one
362 associated with the resolved URL.
363 This is useful when a site employs a video service that hosts the video and
364 its technical metadata, but that video service does not embed a useful
365 title, description etc.
368 Subclasses of this one should re-define the _real_initialize() and
369 _real_extract() methods and define a _VALID_URL regexp.
370 Probably, they should also be added to the list of extractors.
372 _GEO_BYPASS attribute may be set to False in order to disable
373 geo restriction bypass mechanisms for a particular extractor.
374 Though it won't disable explicit geo restriction bypass based on
375 country code provided with geo_bypass_country.
377 _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted
378 countries for this extractor. One of these countries will be used by
379 geo restriction bypass mechanism right away in order to bypass
380 geo restriction, of course, if the mechanism is not disabled.
382 _GEO_IP_BLOCKS attribute may contain a list of presumably geo unrestricted
383 IP blocks in CIDR notation for this extractor. One of these IP blocks
384 will be used by geo restriction bypass mechanism similarly
387 Finally, the _WORKING attribute should be set to False for broken IEs
388 in order to warn the users and skip the tests.
