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

163 "m3u8", "m3u8_native" or "http_dash_segments".
165 Base URL for fragments. Each fragment's path
166 value (if present) will be relative to
168 * fragments A list of fragments of a fragmented media.
169 Each fragment entry must contain either an url
170 or a path. If an url is present it should be
171 considered by a client. Otherwise both path and
172 fragment_base_url must be present. Here is
173 the list of all potential fields:
174 * "url" - fragment's URL
175 * "path" - fragment's path relative to
177 * "duration" (optional, int or float)
178 * "filesize" (optional, int)
179 * preference Order number of this format. If this field is

183 -2 or smaller for less than default.
184 < -1000 to hide the format (if there is
185 another one which is strictly better)
186 * language Language code, e.g. "de" or "en-US".
187 * language_preference Is this in the language mentioned in
189 10 if it's what the URL is about,

199 -2 or smaller for less than default.
200 * http_headers A dictionary of additional HTTP headers
201 to add to the request.
202 * stretched_ratio If given and not 1, indicates that the
203 video's pixels are not square.
204 width : height ratio as float.

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