73 """Information Extractor class.
75 Information extractors are the classes that, given a URL, extract
76 information about the video (or videos) the URL refers to. This
77 information includes the real video URL, the video title, author and
78 others. The information is stored in a dictionary which is then
79 passed to the YoutubeDL. The YoutubeDL processes this
80 information possibly downloading the video to the file system, among
81 other possible outcomes.
83 The type field determines the type of the result.
84 By far the most common value (and the default if _type is missing) is
85 "video", which indicates a single video.
87 For a video, the dictionaries must include the following fields:
90 title: Video title, unescaped.
92 Additionally, it must contain either a formats entry or a url one:
94 formats: A list of dictionaries for each format available, ordered
95 from worst to best quality.
98 * url Mandatory. The URL of the video file
100 The URL of the manifest file in case of
101 fragmented media (DASH, hls, hds)
102 * ext Will be calculated from URL if missing
103 * format A human-readable description of the format
104 ("mp4 container with h264/opus").
105 Calculated from the format_id, width, height.
106 and format_note fields if missing.
107 * format_id A short description of the format
108 ("mp4_h264_opus" or "19").
109 Technically optional, but strongly recommended.
110 * format_note Additional info about the format
111 ("3D" or "DASH video")
112 * width Width of the video, if known
113 * height Height of the video, if known
114 * resolution Textual description of width and height
115 * tbr Average bitrate of audio and video in KBit/s

117 * acodec Name of the audio codec in use
118 * asr Audio sampling rate in Hertz
119 * vbr Average video bitrate in KBit/s
121 * vcodec Name of the video codec in use
122 * container Name of the container format
123 * filesize The number of bytes, if known in advance
124 * filesize_approx An estimate for the number of bytes
125 * player_url SWF Player URL (used for rtmpdump).
126 * protocol The protocol that will be used for the actual
127 download, lower-case.
128 "http", "https", "rtsp", "rtmp", "rtmpe",
129 "m3u8", "m3u8_native" or "http_dash_segments".
131 Base URL for fragments. Each fragment's path
132 value (if present) will be relative to
134 * fragments A list of fragments of a fragmented media.
135 Each fragment entry must contain either an url
136 or a path. If an url is present it should be
137 considered by a client. Otherwise both path and
138 fragment_base_url must be present. Here is
139 the list of all potential fields:
140 * "url" - fragment's URL
141 * "path" - fragment's path relative to
143 * "duration" (optional, int or float)
144 * "filesize" (optional, int)
145 * preference Order number of this format. If this field is
146 present and not None, the formats get sorted
147 by this field, regardless of all other values.
148 -1 for default (order by other properties),
149 -2 or smaller for less than default.
150 < -1000 to hide the format (if there is
151 another one which is strictly better)
152 * language Language code, e.g. "de" or "en-US".
153 * language_preference Is this in the language mentioned in
155 10 if it's what the URL is about,
156 -1 for default (don't know),
157 -10 otherwise, other values reserved for now.
158 * quality Order number of the video quality of this
159 format, irrespective of the file format.
160 -1 for default (order by other properties),
161 -2 or smaller for less than default.

163 (quality takes higher priority)
164 -1 for default (order by other properties),
165 -2 or smaller for less than default.
166 * http_headers A dictionary of additional HTTP headers
167 to add to the request.
168 * stretched_ratio If given and not 1, indicates that the
169 video's pixels are not square.

262 season_id: Id of the season the video episode belongs to, as a unicode string.

287 Unless mentioned otherwise, the fields should be Unicode strings.

292 _type "playlist" indicates multiple videos.
293 There must be a key "entries", which is a list, an iterable, or a PagedList
294 object, each element of which is a valid dictionary by this specification.
296 Additionally, playlists can have "title", "description" and "id" attributes
297 with the same semantics as videos (see above).
300 _type "multi_video" indicates that there are multiple videos that
301 form a single show, for examples multiple acts of an opera or TV episode.
302 It must have an entries key like a playlist and contain all the keys
303 required for a video at the same time.
306 _type "url" indicates that the video must be extracted from another
307 location, possibly by a different extractor. Its only required key is:
308 "url" - the next URL to extract.
309 The key "ie_key" can be set to the class name (minus the trailing "IE",
310 e.g. "Youtube") if the extractor class is known in advance.
311 Additionally, the dictionary may have any properties of the resolved entity
312 known in advance, for example "title" if the title of the referred video is
316 _type "url_transparent" entities have the same specification as "url", but
317 indicate that the given additional information is more precise than the one
318 associated with the resolved URL.
319 This is useful when a site employs a video service that hosts the video and
320 its technical metadata, but that video service does not embed a useful
321 title, description etc.
324 Subclasses of this one should re-define the _real_initialize() and
325 _real_extract() methods and define a _VALID_URL regexp.
326 Probably, they should also be added to the list of extractors.
328 _GEO_BYPASS attribute may be set to False in order to disable
329 geo restriction bypass mechanisms for a particular extractor.
330 Though it won't disable explicit geo restriction bypass based on
331 country code provided with geo_bypass_country. (experimental)
333 _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted
334 countries for this extractor. One of these countries will be used by
335 geo restriction bypass mechanism right away in order to bypass
336 geo restriction, of course, if the mechanism is not disabled. (experimental)
338 NB: both these geo attributes are experimental and may change in future
339 or be completely removed.
341 Finally, the _WORKING attribute should be set to False for broken IEs
342 in order to warn the users and skip the tests.
