79 class InfoExtractor(object):
80 """Information Extractor class.
81
82 Information extractors are the classes that, given a URL, extract
83 information about the video (or videos) the URL refers to. This
84 information includes the real video URL, the video title, author and
85 others. The information is stored in a dictionary which is then
86 passed to the YoutubeDL. The YoutubeDL processes this
87 information possibly downloading the video to the file system, among
88 other possible outcomes.
89
90 The type field determines the type of the result.
91 By far the most common value (and the default if _type is missing) is
92 "video", which indicates a single video.
93
94 For a video, the dictionaries must include the following fields:
95
96 id: Video identifier.
97 title: Video title, unescaped.
98
99 Additionally, it must contain either a formats entry or a url one:
100
101 formats: A list of dictionaries for each format available, ordered
102 from worst to best quality.
103
104 Potential fields:
105 * url Mandatory. The URL of the video file
106 * manifest_url
107 The URL of the manifest file in case of
108 fragmented media (DASH, hls, hds)
109 * ext Will be calculated from URL if missing
110 * format A human-readable description of the format
111 ("mp4 container with h264/opus").
112 Calculated from the format_id, width, height.
113 and format_note fields if missing.
114 * format_id A short description of the format
115 ("mp4_h264_opus" or "19").
116 Technically optional, but strongly recommended.
117 * format_note Additional info about the format
118 ("3D" or "DASH video")
119 * width Width of the video, if known
120 * height Height of the video, if known
121 * resolution Textual description of width and height
122 * tbr Average bitrate of audio and video in KBit/s
123 * abr Average audio bitrate in KBit/s
124 * acodec Name of the audio codec in use
125 * asr Audio sampling rate in Hertz
126 * vbr Average video bitrate in KBit/s
127 * fps Frame rate
128 * vcodec Name of the video codec in use
129 * container Name of the container format
130 * filesize The number of bytes, if known in advance
131 * filesize_approx An estimate for the number of bytes
132 * player_url SWF Player URL (used for rtmpdump).
133 * protocol The protocol that will be used for the actual
134 download, lower-case.
135 "http", "https", "rtsp", "rtmp", "rtmpe",
136 "m3u8", "m3u8_native" or "http_dash_segments".
137 * fragment_base_url
138 Base URL for fragments. Each fragment's path
139 value (if present) will be relative to
140 this URL.
141 * fragments A list of fragments of a fragmented media.
142 Each fragment entry must contain either an url
143 or a path. If an url is present it should be
144 considered by a client. Otherwise both path and
145 fragment_base_url must be present. Here is
146 the list of all potential fields:
147 * "url" - fragment's URL
148 * "path" - fragment's path relative to
149 fragment_base_url
150 * "duration" (optional, int or float)
151 * "filesize" (optional, int)
152 * preference Order number of this format. If this field is
153 present and not None, the formats get sorted
154 by this field, regardless of all other values.
155 -1 for default (order by other properties),
156 -2 or smaller for less than default.
157 < -1000 to hide the format (if there is
158 another one which is strictly better)
159 * language Language code, e.g. "de" or "en-US".
160 * language_preference Is this in the language mentioned in
161 the URL?
162 10 if it's what the URL is about,
163 -1 for default (don't know),
164 -10 otherwise, other values reserved for now.
165 * quality Order number of the video quality of this
166 format, irrespective of the file format.
167 -1 for default (order by other properties),
168 -2 or smaller for less than default.
169 * source_preference Order number for this video source
170 (quality takes higher priority)
171 -1 for default (order by other properties),
172 -2 or smaller for less than default.
173 * http_headers A dictionary of additional HTTP headers
174 to add to the request.
175 * stretched_ratio If given and not 1, indicates that the
176 video's pixels are not square.
177 width : height ratio as float.
178 * no_resume The server does not support resuming the
179 (HTTP or RTMP) download. Boolean.
180 * downloader_options A dictionary of downloader options as
181 described in FileDownloader
182

271 chapter_number: Number of the chapter the video belongs to, as an integer.
272 chapter_id: Id of the chapter the video belongs to, as a unicode string.
273
274 The following fields should only be used when the video is an episode of some
275 series, programme or podcast:
276
277 series: Title of the series or programme the video episode belongs to.
278 season: Title of the season the video episode belongs to.
279 season_number: Number of the season the video episode belongs to, as an integer.
280 season_id: Id of the season the video episode belongs to, as a unicode string.
281 episode: Title of the video episode. Unlike mandatory video title field,
282 this field should denote the exact title of the video episode
283 without any kind of decoration.
284 episode_number: Number of the video episode within a season, as an integer.
285 episode_id: Id of the video episode, as a unicode string.

288 a music album:
289
290 track: Title of the track.
291 track_number: Number of the track within an album or a disc, as an integer.

296 album: Title of the album the track belongs to.
297 album_type: Type of the album (e.g. "Demo", "Full-length", "Split", "Compilation", etc).
298 album_artist: List of all artists appeared on the album (e.g.
299 "Ash Borer / Fell Voices" or "Various Artists", useful for splits
300 and compilations).
301 disc_number: Number of the disc or other physical medium the track belongs to,
302 as an integer.
303 release_year: Year (YYYY) when the album was released.
304
305 Unless mentioned otherwise, the fields should be Unicode strings.
306
307 Unless mentioned otherwise, None is equivalent to absence of information.
308
309
310 _type "playlist" indicates multiple videos.
311 There must be a key "entries", which is a list, an iterable, or a PagedList
312 object, each element of which is a valid dictionary by this specification.
313
314 Additionally, playlists can have "id", "title", "description", "uploader",
315 "uploader_id", "uploader_url" attributes with the same semantics as videos
316 (see above).
317
318
319 _type "multi_video" indicates that there are multiple videos that
320 form a single show, for examples multiple acts of an opera or TV episode.
321 It must have an entries key like a playlist and contain all the keys
322 required for a video at the same time.
323
324
325 _type "url" indicates that the video must be extracted from another
326 location, possibly by a different extractor. Its only required key is:
327 "url" - the next URL to extract.
328 The key "ie_key" can be set to the class name (minus the trailing "IE",
329 e.g. "Youtube") if the extractor class is known in advance.
330 Additionally, the dictionary may have any properties of the resolved entity
331 known in advance, for example "title" if the title of the referred video is
332 known ahead of time.
333
334
335 _type "url_transparent" entities have the same specification as "url", but
336 indicate that the given additional information is more precise than the one
337 associated with the resolved URL.
338 This is useful when a site employs a video service that hosts the video and
339 its technical metadata, but that video service does not embed a useful
340 title, description etc.
341
342
343 Subclasses of this one should re-define the _real_initialize() and
344 _real_extract() methods and define a _VALID_URL regexp.
345 Probably, they should also be added to the list of extractors.
346
347 _GEO_BYPASS attribute may be set to False in order to disable
348 geo restriction bypass mechanisms for a particular extractor.
349 Though it won't disable explicit geo restriction bypass based on
350 country code provided with geo_bypass_country.
351
352 _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted
353 countries for this extractor. One of these countries will be used by
354 geo restriction bypass mechanism right away in order to bypass
355 geo restriction, of course, if the mechanism is not disabled.
356
357 _GEO_IP_BLOCKS attribute may contain a list of presumably geo unrestricted
358 IP blocks in CIDR notation for this extractor. One of these IP blocks
359 will be used by geo restriction bypass mechanism similarly
360 to _GEO_COUNTRIES.
361
362 Finally, the _WORKING attribute should be set to False for broken IEs
363 in order to warn the users and skip the tests.
