74 """Information Extractor class.
76 Information extractors are the classes that, given a URL, extract
77 information about the video (or videos) the URL refers to. This
78 information includes the real video URL, the video title, author and
79 others. The information is stored in a dictionary which is then
80 passed to the YoutubeDL. The YoutubeDL processes this
81 information possibly downloading the video to the file system, among
82 other possible outcomes.
84 The type field determines the type of the result.
85 By far the most common value (and the default if _type is missing) is
86 "video", which indicates a single video.
88 For a video, the dictionaries must include the following fields:
91 title: Video title, unescaped.
93 Additionally, it must contain either a formats entry or a url one:
95 formats: A list of dictionaries for each format available, ordered
96 from worst to best quality.
99 * url Mandatory. The URL of the video file
101 The URL of the manifest file in case of
102 fragmented media (DASH, hls, hds)
103 * ext Will be calculated from URL if missing
104 * format A human-readable description of the format
105 ("mp4 container with h264/opus").
106 Calculated from the format_id, width, height.
107 and format_note fields if missing.
108 * format_id A short description of the format
109 ("mp4_h264_opus" or "19").
110 Technically optional, but strongly recommended.
111 * format_note Additional info about the format
112 ("3D" or "DASH video")
113 * width Width of the video, if known
114 * height Height of the video, if known
115 * resolution Textual description of width and height
116 * tbr Average bitrate of audio and video in KBit/s
117 * abr Average audio bitrate in KBit/s
118 * acodec Name of the audio codec in use
119 * asr Audio sampling rate in Hertz
120 * vbr Average video bitrate in KBit/s
122 * vcodec Name of the video codec in use
123 * container Name of the container format
124 * filesize The number of bytes, if known in advance
125 * filesize_approx An estimate for the number of bytes
126 * player_url SWF Player URL (used for rtmpdump).
127 * protocol The protocol that will be used for the actual
128 download, lower-case.
129 "http", "https", "rtsp", "rtmp", "rtmpe",
130 "m3u8", "m3u8_native" or "http_dash_segments".
132 Base URL for fragments. Each fragment's path
133 value (if present) will be relative to
135 * fragments A list of fragments of a fragmented media.
136 Each fragment entry must contain either an url
137 or a path. If an url is present it should be
138 considered by a client. Otherwise both path and
139 fragment_base_url must be present. Here is
140 the list of all potential fields:
141 * "url" - fragment's URL
142 * "path" - fragment's path relative to
144 * "duration" (optional, int or float)
145 * "filesize" (optional, int)
146 * preference Order number of this format. If this field is
147 present and not None, the formats get sorted
148 by this field, regardless of all other values.
149 -1 for default (order by other properties),
150 -2 or smaller for less than default.
151 < -1000 to hide the format (if there is
152 another one which is strictly better)
153 * language Language code, e.g. "de" or "en-US".
154 * language_preference Is this in the language mentioned in
156 10 if it's what the URL is about,
157 -1 for default (don't know),
158 -10 otherwise, other values reserved for now.
159 * quality Order number of the video quality of this
160 format, irrespective of the file format.
161 -1 for default (order by other properties),
162 -2 or smaller for less than default.
163 * source_preference Order number for this video source
164 (quality takes higher priority)
165 -1 for default (order by other properties),
166 -2 or smaller for less than default.
167 * http_headers A dictionary of additional HTTP headers
168 to add to the request.
169 * stretched_ratio If given and not 1, indicates that the
170 video's pixels are not square.
171 width : height ratio as float.
172 * no_resume The server does not support resuming the
173 (HTTP or RTMP) download. Boolean.

242 tags: A list of tags assigned to the video, e.g. ["sweden", "pop music"]

265 season: Title of the season the video episode belongs to.
266 season_number: Number of the season the video episode belongs to, as an integer.
267 season_id: Id of the season the video episode belongs to, as a unicode string.
268 episode: Title of the video episode. Unlike mandatory video title field,
269 this field should denote the exact title of the video episode
270 without any kind of decoration.
271 episode_number: Number of the video episode within a season, as an integer.
272 episode_id: Id of the video episode, as a unicode string.

290 release_year: Year (YYYY) when the album was released.
292 Unless mentioned otherwise, the fields should be Unicode strings.
294 Unless mentioned otherwise, None is equivalent to absence of information.
297 _type "playlist" indicates multiple videos.
298 There must be a key "entries", which is a list, an iterable, or a PagedList
299 object, each element of which is a valid dictionary by this specification.
301 Additionally, playlists can have "title", "description" and "id" attributes
302 with the same semantics as videos (see above).
305 _type "multi_video" indicates that there are multiple videos that
306 form a single show, for examples multiple acts of an opera or TV episode.
307 It must have an entries key like a playlist and contain all the keys
308 required for a video at the same time.
311 _type "url" indicates that the video must be extracted from another
312 location, possibly by a different extractor. Its only required key is:
313 "url" - the next URL to extract.
314 The key "ie_key" can be set to the class name (minus the trailing "IE",
315 e.g. "Youtube") if the extractor class is known in advance.
316 Additionally, the dictionary may have any properties of the resolved entity
317 known in advance, for example "title" if the title of the referred video is
321 _type "url_transparent" entities have the same specification as "url", but
322 indicate that the given additional information is more precise than the one
323 associated with the resolved URL.
324 This is useful when a site employs a video service that hosts the video and
325 its technical metadata, but that video service does not embed a useful
326 title, description etc.
329 Subclasses of this one should re-define the _real_initialize() and
330 _real_extract() methods and define a _VALID_URL regexp.
331 Probably, they should also be added to the list of extractors.
333 _GEO_BYPASS attribute may be set to False in order to disable
334 geo restriction bypass mechanisms for a particular extractor.
335 Though it won't disable explicit geo restriction bypass based on
336 country code provided with geo_bypass_country. (experimental)
338 _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted
339 countries for this extractor. One of these countries will be used by
340 geo restriction bypass mechanism right away in order to bypass
341 geo restriction, of course, if the mechanism is not disabled. (experimental)
343 NB: both these geo attributes are experimental and may change in future
344 or be completely removed.
346 Finally, the _WORKING attribute should be set to False for broken IEs
347 in order to warn the users and skip the tests.
