92 """Information Extractor class.
94 Information extractors are the classes that, given a URL, extract
95 information about the video (or videos) the URL refers to. This
96 information includes the real video URL, the video title, author and
97 others. The information is stored in a dictionary which is then
98 passed to the YoutubeDL. The YoutubeDL processes this
99 information possibly downloading the video to the file system, among
100 other possible outcomes.
102 The type field determines the type of the result.
103 By far the most common value (and the default if _type is missing) is
104 "video", which indicates a single video.
106 For a video, the dictionaries must include the following fields:
108 id: Video identifier.
109 title: Video title, unescaped. Set to an empty string if video has
110 no title as opposed to "None" which signifies that the
111 extractor failed to obtain a title
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 * manifest_stream_number (For internal use only)

145 and format_note fields if missing.
146 * format_id A short description of the format
147 ("mp4_h264_opus" or "19").

152 * height Height of the video, if known
153 * resolution Textual description of width and height

165 * filesize The number of bytes, if known in advance
166 * filesize_approx An estimate for the number of bytes
167 * player_url SWF Player URL (used for rtmpdump).
168 * protocol The protocol that will be used for the actual
169 download, lower-case. One of "http", "https" or
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

204 -2 or smaller for less than default.
205 * source_preference Order number for this video source
206 (quality takes higher priority)

208 -2 or smaller for less than default.
209 * http_headers A dictionary of additional HTTP headers
210 to add to the request.

345 written to either disk, logger or console. The function
346 must return a dict which will be added to the info_dict.
347 This is usefull for additional information that is
348 time-consuming to extract. Note that the fields thus
349 extracted will not be available to output template and
350 match_filter. So, only "comments" and "comment_count" are
351 currently allowed to be extracted via this method.
353 The following fields should only be used when the video belongs to some logical
356 chapter: Name or title of the chapter the video belongs to.
357 chapter_number: Number of the chapter the video belongs to, as an integer.
358 chapter_id: Id of the chapter the video belongs to, as a unicode string.
360 The following fields should only be used when the video is an episode of some
361 series, programme or podcast:
363 series: Title of the series or programme the video episode belongs to.
364 series_id: Id of the series or programme the video episode belongs to, as a unicode string.
365 season: Title of the season the video episode belongs to.
366 season_number: Number of the season the video episode belongs to, as an integer.
367 season_id: Id of the season the video episode belongs to, as a unicode string.
368 episode: Title of the video episode. Unlike mandatory video title field,
369 this field should denote the exact title of the video episode
370 without any kind of decoration.
371 episode_number: Number of the video episode within a season, as an integer.
372 episode_id: Id of the video episode, as a unicode string.
374 The following fields should only be used when the media is a track or a part of
377 track: Title of the track.
378 track_number: Number of the track within an album or a disc, as an integer.
379 track_id: Id of the track (useful in case of custom indexing, e.g. 6.iii),
381 artist: Artist(s) of the track.
382 genre: Genre(s) of the track.
383 album: Title of the album the track belongs to.
384 album_type: Type of the album (e.g. "Demo", "Full-length", "Split", "Compilation", etc).
385 album_artist: List of all artists appeared on the album (e.g.
386 "Ash Borer / Fell Voices" or "Various Artists", useful for splits
388 disc_number: Number of the disc or other physical medium the track belongs to,
390 release_year: Year (YYYY) when the album was released.
391 composer: Composer of the piece
393 The following fields should only be set for clips that should be cut from the original video:
395 section_start: Start time of the section in seconds
396 section_end: End time of the section in seconds
398 The following fields should only be set for storyboards:
399 rows: Number of rows in each storyboard fragment, as an integer
400 columns: Number of columns in each storyboard fragment, as an integer
402 Unless mentioned otherwise, the fields should be Unicode strings.
404 Unless mentioned otherwise, None is equivalent to absence of information.
407 _type "playlist" indicates multiple videos.
408 There must be a key "entries", which is a list, an iterable, or a PagedList
409 object, each element of which is a valid dictionary by this specification.
411 Additionally, playlists can have "id", "title", and any other relevant
412 attributes with the same semantics as videos (see above).
414 It can also have the following optional fields:
416 playlist_count: The total number of videos in a playlist. If not given,
417 YoutubeDL tries to calculate it from "entries"
420 _type "multi_video" indicates that there are multiple videos that
421 form a single show, for examples multiple acts of an opera or TV episode.
422 It must have an entries key like a playlist and contain all the keys
423 required for a video at the same time.
426 _type "url" indicates that the video must be extracted from another
427 location, possibly by a different extractor. Its only required key is:
428 "url" - the next URL to extract.
429 The key "ie_key" can be set to the class name (minus the trailing "IE",
430 e.g. "Youtube") if the extractor class is known in advance.
431 Additionally, the dictionary may have any properties of the resolved entity
432 known in advance, for example "title" if the title of the referred video is
436 _type "url_transparent" entities have the same specification as "url", but
437 indicate that the given additional information is more precise than the one
438 associated with the resolved URL.
439 This is useful when a site employs a video service that hosts the video and
440 its technical metadata, but that video service does not embed a useful
441 title, description etc.
444 Subclasses of this should also be added to the list of extractors and
445 should define a _VALID_URL regexp and, re-define the _real_extract() and
446 (optionally) _real_initialize() methods.
448 Subclasses may also override suitable() if necessary, but ensure the function
449 signature is preserved and that this function imports everything it needs
450 (except other extractors), so that lazy_extractors works correctly.
452 Subclasses can define a list of _EMBED_REGEX, which will be searched for in
453 the HTML of Generic webpages. It may also override _extract_embed_urls
454 or _extract_from_webpage as necessary. While these are normally classmethods,
455 _extract_from_webpage is allowed to be an instance method.
457 _extract_from_webpage may raise self.StopExtraction() to stop further
458 processing of the webpage and obtain exclusive rights to it. This is useful
459 when the extractor cannot reliably be matched using just the URL,
460 e.g. invidious/peertube instances
462 Embed-only extractors can be defined by setting _VALID_URL = False.
464 To support username + password (or netrc) login, the extractor must define a
465 _NETRC_MACHINE and re-define _perform_login(username, password) and
466 (optionally) _initialize_pre_login() methods. The _perform_login method will
467 be called between _initialize_pre_login and _real_initialize if credentials
468 are passed by the user. In cases where it is necessary to have the login
469 process as part of the extraction rather than initialization, _perform_login
470 can be left undefined.
472 _GEO_BYPASS attribute may be set to False in order to disable
473 geo restriction bypass mechanisms for a particular extractor.
474 Though it won't disable explicit geo restriction bypass based on
475 country code provided with geo_bypass_country.
477 _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted
478 countries for this extractor. One of these countries will be used by
479 geo restriction bypass mechanism right away in order to bypass
480 geo restriction, of course, if the mechanism is not disabled.
482 _GEO_IP_BLOCKS attribute may contain a list of presumably geo unrestricted
483 IP blocks in CIDR notation for this extractor. One of these IP blocks
484 will be used by geo restriction bypass mechanism similarly
487 The _ENABLED attribute should be set to False for IEs that
488 are disabled by default and must be explicitly enabled.
490 The _WORKING attribute should be set to False for broken IEs
491 in order to warn the users and skip the tests.
