94 """Information Extractor class.
96 Information extractors are the classes that, given a URL, extract
97 information about the video (or videos) the URL refers to. This
98 information includes the real video URL, the video title, author and
99 others. The information is stored in a dictionary which is then
100 passed to the YoutubeDL. The YoutubeDL processes this
101 information possibly downloading the video to the file system, among
102 other possible outcomes.
104 The type field determines the type of the result.
105 By far the most common value (and the default if _type is missing) is
106 "video", which indicates a single video.
108 For a video, the dictionaries must include the following fields:
110 id: Video identifier.
111 title: Video title, unescaped.
113 Additionally, it must contain either a formats entry or a url one:
115 formats: A list of dictionaries for each format available, ordered
116 from worst to best quality.
119 * url The mandatory URL representing the media:
120 for plain file media - HTTP URL of this file,
122 for HLS - URL of the M3U8 media playlist,
123 for HDS - URL of the F4M manifest,
125 - HTTP URL to plain file media (in case of
127 - URL of the MPD manifest or base URL
128 representing the media if MPD manifest
129 is parsed from a string (in case of
131 for MSS - URL of the ISM manifest.
133 The URL of the manifest file in case of
135 for HLS - URL of the M3U8 master playlist,
136 for HDS - URL of the F4M manifest,
137 for DASH - URL of the MPD manifest,
138 for MSS - URL of the ISM manifest.
139 * ext Will be calculated from URL if missing
140 * format A human-readable description of the format
141 ("mp4 container with h264/opus").
142 Calculated from the format_id, width, height.
143 and format_note fields if missing.
144 * format_id A short description of the format
145 ("mp4_h264_opus" or "19").
146 Technically optional, but strongly recommended.
147 * format_note Additional info about the format
148 ("3D" or "DASH video")
149 * width Width of the video, if known
150 * height Height of the video, if known
151 * resolution Textual description of width and height

165 * protocol The protocol that will be used for the actual
166 download, lower-case. One of "http", "https" or
167 one of the protocols defined in downloader.PROTOCOL_MAP
169 Base URL for fragments. Each fragment's path
170 value (if present) will be relative to
172 * fragments A list of fragments of a fragmented media.
173 Each fragment entry must contain either an url
174 or a path. If an url is present it should be
175 considered by a client. Otherwise both path and
176 fragment_base_url must be present. Here is
177 the list of all potential fields:
178 * "url" - fragment's URL
179 * "path" - fragment's path relative to

187 by this field, regardless of all other values.
188 -1 for default (order by other properties),
189 -2 or smaller for less than default.
190 < -1000 to hide the format (if there is
191 another one which is strictly better)
192 * language Language code, e.g. "de" or "en-US".

205 -2 or smaller for less than default.
206 * http_headers A dictionary of additional HTTP headers
207 to add to the request.
208 * stretched_ratio If given and not 1, indicates that the
209 video's pixels are not square.
210 width : height ratio as float.

326 __post_extractor: A function to be called just before the metadata is
327 written to either disk, logger or console. The function
328 must return a dict which will be added to the info_dict.
329 This is usefull for additional information that is
330 time-consuming to extract. Note that the fields thus
331 extracted will not be available to output template and

333 currently allowed to be extracted via this method.
335 The following fields should only be used when the video belongs to some logical
338 chapter: Name or title of the chapter the video belongs to.
339 chapter_number: Number of the chapter the video belongs to, as an integer.
340 chapter_id: Id of the chapter the video belongs to, as a unicode string.
342 The following fields should only be used when the video is an episode of some
343 series, programme or podcast:
345 series: Title of the series or programme the video episode belongs to.
346 series_id: Id of the series or programme the video episode belongs to, as a unicode string.
347 season: Title of the season the video episode belongs to.
348 season_number: Number of the season the video episode belongs to, as an integer.
349 season_id: Id of the season the video episode belongs to, as a unicode string.
350 episode: Title of the video episode. Unlike mandatory video title field,
351 this field should denote the exact title of the video episode
352 without any kind of decoration.
353 episode_number: Number of the video episode within a season, as an integer.
354 episode_id: Id of the video episode, as a unicode string.
356 The following fields should only be used when the media is a track or a part of
359 track: Title of the track.
360 track_number: Number of the track within an album or a disc, as an integer.
361 track_id: Id of the track (useful in case of custom indexing, e.g. 6.iii),
363 artist: Artist(s) of the track.
364 genre: Genre(s) of the track.
365 album: Title of the album the track belongs to.
366 album_type: Type of the album (e.g. "Demo", "Full-length", "Split", "Compilation", etc).
367 album_artist: List of all artists appeared on the album (e.g.
368 "Ash Borer / Fell Voices" or "Various Artists", useful for splits
370 disc_number: Number of the disc or other physical medium the track belongs to,
372 release_year: Year (YYYY) when the album was released.
374 Unless mentioned otherwise, the fields should be Unicode strings.
376 Unless mentioned otherwise, None is equivalent to absence of information.
379 _type "playlist" indicates multiple videos.
380 There must be a key "entries", which is a list, an iterable, or a PagedList
381 object, each element of which is a valid dictionary by this specification.
383 Additionally, playlists can have "id", "title", and any other relevent
384 attributes with the same semantics as videos (see above).
387 _type "multi_video" indicates that there are multiple videos that
388 form a single show, for examples multiple acts of an opera or TV episode.
389 It must have an entries key like a playlist and contain all the keys
390 required for a video at the same time.
393 _type "url" indicates that the video must be extracted from another
394 location, possibly by a different extractor. Its only required key is:
395 "url" - the next URL to extract.
396 The key "ie_key" can be set to the class name (minus the trailing "IE",
397 e.g. "Youtube") if the extractor class is known in advance.
398 Additionally, the dictionary may have any properties of the resolved entity
399 known in advance, for example "title" if the title of the referred video is
403 _type "url_transparent" entities have the same specification as "url", but
404 indicate that the given additional information is more precise than the one
405 associated with the resolved URL.
406 This is useful when a site employs a video service that hosts the video and
407 its technical metadata, but that video service does not embed a useful
408 title, description etc.
411 Subclasses of this one should re-define the _real_initialize() and
412 _real_extract() methods and define a _VALID_URL regexp.
413 Probably, they should also be added to the list of extractors.
415 Subclasses may also override suitable() if necessary, but ensure the function
416 signature is preserved and that this function imports everything it needs
417 (except other extractors), so that lazy_extractors works correctly
419 _GEO_BYPASS attribute may be set to False in order to disable
420 geo restriction bypass mechanisms for a particular extractor.
421 Though it won't disable explicit geo restriction bypass based on
422 country code provided with geo_bypass_country.
424 _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted
425 countries for this extractor. One of these countries will be used by
426 geo restriction bypass mechanism right away in order to bypass
427 geo restriction, of course, if the mechanism is not disabled.
429 _GEO_IP_BLOCKS attribute may contain a list of presumably geo unrestricted
430 IP blocks in CIDR notation for this extractor. One of these IP blocks
431 will be used by geo restriction bypass mechanism similarly
434 The _WORKING attribute should be set to False for broken IEs
435 in order to warn the users and skip the tests.
