86 """Information Extractor class.
88 Information extractors are the classes that, given a URL, extract
89 information about the video (or videos) the URL refers to. This
90 information includes the real video URL, the video title, author and
91 others. The information is stored in a dictionary which is then
92 passed to the YoutubeDL. The YoutubeDL processes this
93 information possibly downloading the video to the file system, among
94 other possible outcomes.
96 The type field determines the type of the result.
97 By far the most common value (and the default if _type is missing) is
98 "video", which indicates a single video.
100 For a video, the dictionaries must include the following fields:
102 id: Video identifier.
103 title: Video title, unescaped.
105 Additionally, it must contain either a formats entry or a url one:
107 formats: A list of dictionaries for each format available, ordered
108 from worst to best quality.
111 * url The mandatory URL representing the media:
112 for plain file media - HTTP URL of this file,
114 for HLS - URL of the M3U8 media playlist,
115 for HDS - URL of the F4M manifest,
117 - HTTP URL to plain file media (in case of
119 - URL of the MPD manifest or base URL
120 representing the media if MPD manifest
121 is parsed from a string (in case of
123 for MSS - URL of the ISM manifest.
125 The URL of the manifest file in case of
127 for HLS - URL of the M3U8 master playlist,
128 for HDS - URL of the F4M manifest,
129 for DASH - URL of the MPD manifest,
130 for MSS - URL of the ISM manifest.

161 value (if present) will be relative to
163 * fragments A list of fragments of a fragmented media.
164 Each fragment entry must contain either an url
165 or a path. If an url is present it should be

301 season_number: Number of the season the video episode belongs to, as an integer.
302 season_id: Id of the season the video episode belongs to, as a unicode string.

327 Unless mentioned otherwise, the fields should be Unicode strings.
329 Unless mentioned otherwise, None is equivalent to absence of information.
332 _type "playlist" indicates multiple videos.
333 There must be a key "entries", which is a list, an iterable, or a PagedList
334 object, each element of which is a valid dictionary by this specification.
336 Additionally, playlists can have "id", "title", "description", "uploader",
337 "uploader_id", "uploader_url" attributes with the same semantics as videos
341 _type "multi_video" indicates that there are multiple videos that
342 form a single show, for examples multiple acts of an opera or TV episode.
343 It must have an entries key like a playlist and contain all the keys
344 required for a video at the same time.
347 _type "url" indicates that the video must be extracted from another
348 location, possibly by a different extractor. Its only required key is:
349 "url" - the next URL to extract.
350 The key "ie_key" can be set to the class name (minus the trailing "IE",
351 e.g. "Youtube") if the extractor class is known in advance.
352 Additionally, the dictionary may have any properties of the resolved entity
353 known in advance, for example "title" if the title of the referred video is
357 _type "url_transparent" entities have the same specification as "url", but
358 indicate that the given additional information is more precise than the one
359 associated with the resolved URL.
360 This is useful when a site employs a video service that hosts the video and
361 its technical metadata, but that video service does not embed a useful
362 title, description etc.
365 Subclasses of this one should re-define the _real_initialize() and
366 _real_extract() methods and define a _VALID_URL regexp.
367 Probably, they should also be added to the list of extractors.
369 _GEO_BYPASS attribute may be set to False in order to disable
370 geo restriction bypass mechanisms for a particular extractor.
371 Though it won't disable explicit geo restriction bypass based on
372 country code provided with geo_bypass_country.
374 _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted
375 countries for this extractor. One of these countries will be used by
376 geo restriction bypass mechanism right away in order to bypass
377 geo restriction, of course, if the mechanism is not disabled.
379 _GEO_IP_BLOCKS attribute may contain a list of presumably geo unrestricted
380 IP blocks in CIDR notation for this extractor. One of these IP blocks
381 will be used by geo restriction bypass mechanism similarly
384 Finally, the _WORKING attribute should be set to False for broken IEs
385 in order to warn the users and skip the tests.
