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

151 ("3D" or "DASH video")
152 * width Width of the video, if known
153 * height Height of the video, if known
154 * resolution Textual description of width and height

170 one of the protocols defined in downloader.PROTOCOL_MAP
172 Base URL for fragments. Each fragment's path
173 value (if present) will be relative to
175 * fragments A list of fragments of a fragmented media.
176 Each fragment entry must contain either an url
177 or a path. If an url is present it should be
178 considered by a client. Otherwise both path and

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

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

346 currently allowed to be extracted via this method.
348 The following fields should only be used when the video belongs to some logical
351 chapter: Name or title of the chapter the video belongs to.
352 chapter_number: Number of the chapter the video belongs to, as an integer.

355 The following fields should only be used when the video is an episode of some
356 series, programme or podcast:
358 series: Title of the series or programme the video episode belongs to.
359 series_id: Id of the series or programme the video episode belongs to, as a unicode string.
360 season: Title of the season the video episode belongs to.
361 season_number: Number of the season the video episode belongs to, as an integer.
362 season_id: Id of the season the video episode belongs to, as a unicode string.
363 episode: Title of the video episode. Unlike mandatory video title field,
364 this field should denote the exact title of the video episode
365 without any kind of decoration.
366 episode_number: Number of the video episode within a season, as an integer.
367 episode_id: Id of the video episode, as a unicode string.
369 The following fields should only be used when the media is a track or a part of
372 track: Title of the track.
373 track_number: Number of the track within an album or a disc, as an integer.
374 track_id: Id of the track (useful in case of custom indexing, e.g. 6.iii),
376 artist: Artist(s) of the track.
377 genre: Genre(s) of the track.
378 album: Title of the album the track belongs to.
379 album_type: Type of the album (e.g. "Demo", "Full-length", "Split", "Compilation", etc).
380 album_artist: List of all artists appeared on the album (e.g.
381 "Ash Borer / Fell Voices" or "Various Artists", useful for splits
383 disc_number: Number of the disc or other physical medium the track belongs to,
385 release_year: Year (YYYY) when the album was released.
386 composer: Composer of the piece
388 Unless mentioned otherwise, the fields should be Unicode strings.
390 Unless mentioned otherwise, None is equivalent to absence of information.
393 _type "playlist" indicates multiple videos.
394 There must be a key "entries", which is a list, an iterable, or a PagedList
395 object, each element of which is a valid dictionary by this specification.
397 Additionally, playlists can have "id", "title", and any other relevent
398 attributes with the same semantics as videos (see above).
400 It can also have the following optional fields:
402 playlist_count: The total number of videos in a playlist. If not given,
403 YoutubeDL tries to calculate it from "entries"
406 _type "multi_video" indicates that there are multiple videos that
407 form a single show, for examples multiple acts of an opera or TV episode.
408 It must have an entries key like a playlist and contain all the keys
409 required for a video at the same time.
412 _type "url" indicates that the video must be extracted from another
413 location, possibly by a different extractor. Its only required key is:
414 "url" - the next URL to extract.
415 The key "ie_key" can be set to the class name (minus the trailing "IE",
416 e.g. "Youtube") if the extractor class is known in advance.
417 Additionally, the dictionary may have any properties of the resolved entity
418 known in advance, for example "title" if the title of the referred video is
422 _type "url_transparent" entities have the same specification as "url", but
423 indicate that the given additional information is more precise than the one
424 associated with the resolved URL.
425 This is useful when a site employs a video service that hosts the video and
426 its technical metadata, but that video service does not embed a useful
427 title, description etc.
430 Subclasses of this should define a _VALID_URL regexp and, re-define the
431 _real_extract() and (optionally) _real_initialize() methods.
432 Probably, they should also be added to the list of extractors.
434 Subclasses may also override suitable() if necessary, but ensure the function
435 signature is preserved and that this function imports everything it needs
436 (except other extractors), so that lazy_extractors works correctly.
438 To support username + password (or netrc) login, the extractor must define a
439 _NETRC_MACHINE and re-define _perform_login(username, password) and
440 (optionally) _initialize_pre_login() methods. The _perform_login method will
441 be called between _initialize_pre_login and _real_initialize if credentials
442 are passed by the user. In cases where it is necessary to have the login
443 process as part of the extraction rather than initialization, _perform_login
444 can be left undefined.
446 _GEO_BYPASS attribute may be set to False in order to disable
447 geo restriction bypass mechanisms for a particular extractor.
448 Though it won't disable explicit geo restriction bypass based on
449 country code provided with geo_bypass_country.
451 _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted
452 countries for this extractor. One of these countries will be used by
453 geo restriction bypass mechanism right away in order to bypass
454 geo restriction, of course, if the mechanism is not disabled.
456 _GEO_IP_BLOCKS attribute may contain a list of presumably geo unrestricted
457 IP blocks in CIDR notation for this extractor. One of these IP blocks
458 will be used by geo restriction bypass mechanism similarly
461 The _WORKING attribute should be set to False for broken IEs
462 in order to warn the users and skip the tests.
