Note that the fields thus + extracted will not be available to output template and + match_filter. So, only "comments" and "comment_count" are + currently allowed to be extracted via this method. + + The following fields should only be used when the video belongs to some logical + chapter or section: + + chapter: Name or title of the chapter the video belongs to. + chapter_number: Number of the chapter the video belongs to, as an integer. + chapter_id: Id of the chapter the video belongs to, as a unicode string. + + The following fields should only be used when the video is an episode of some + series, programme or podcast: + + series: Title of the series or programme the video episode belongs to. + series_id: Id of the series or programme the video episode belongs to, as a unicode string. + season: Title of the season the video episode belongs to. + season_number: Number of the season the video episode belongs to, as an integer. + season_id: Id of the season the video episode belongs to, as a unicode string. + episode: Title of the video episode. Unlike mandatory video title field, + this field should denote the exact title of the video episode + without any kind of decoration. + episode_number: Number of the video episode within a season, as an integer. + episode_id: Id of the video episode, as a unicode string. + + The following fields should only be used when the media is a track or a part of + a music album: + + track: Title of the track. + track_number: Number of the track within an album or a disc, as an integer. + track_id: Id of the track (useful in case of custom indexing, e.g. 6.iii), + as a unicode string. + artists: List of artists of the track. + composers: List of composers of the piece. + genres: List of genres of the track. + album: Title of the album the track belongs to. + album_type: Type of the album (e.g. "Demo", "Full-length", "Split", "Compilation", etc). + album_artists: List of all artists appeared on the album. + E.g. ["Ash Borer", "Fell Voices"] or ["Various Artists"]. + Useful for splits and compilations. + disc_number: Number of the disc or other physical medium the track belongs to, + as an integer. + + The following fields should only be set for clips that should be cut from the original video: + + section_start: Start time of the section in seconds + section_end: End time of the section in seconds + + The following fields should only be set for storyboards: + rows: Number of rows in each storyboard fragment, as an integer + columns: Number of columns in each storyboard fragment, as an integer + + The following fields are deprecated and should not be set by new code: + composer: Use "composers" instead. + Composer(s) of the piece, comma-separated. + artist: Use "artists" instead. + Artist(s) of the track, comma-separated. + genre: Use "genres" instead. + Genre(s) of the track, comma-separated. + album_artist: Use "album_artists" instead. + All artists appeared on the album, comma-separated. + creator: Use "creators" instead. + The creator of the video. + + Unless mentioned otherwise, the fields should be Unicode strings. + + Unless mentioned otherwise, None is equivalent to absence of information. + + + _type "playlist" indicates multiple videos. + There must be a key "entries", which is a list, an iterable, or a PagedList + object, each element of which is a valid dictionary by this specification. + + Additionally, playlists can have "id", "title", and any other relevant + attributes with the same semantics as videos (see above). + + It can also have the following optional fields: + + playlist_count: The total number of videos in a playlist. If not given, + YoutubeDL tries to calculate it from "entries" + + + _type "multi_video" indicates that there are multiple videos that + form a single show, for examples multiple acts of an opera or TV episode. + It must have an entries key like a playlist and contain all the keys + required for a video at the same time. + + + _type "url" indicates that the video must be extracted from another + location, possibly by a different extractor. Its only required key is: + "url" - the next URL to extract. + The key "ie_key" can be set to the class name (minus the trailing "IE", + e.g. "Youtube") if the extractor class is known in advance. + Additionally, the dictionary may have any properties of the resolved entity + known in advance, for example "title" if the title of the referred video is + known ahead of time. + + + _type "url_transparent" entities have the same specification as "url", but + indicate that the given additional information is more precise than the one + associated with the resolved URL. + This is useful when a site employs a video service that hosts the video and + its technical metadata, but that video service does not embed a useful + title, description etc. + + + Subclasses of this should also be added to the list of extractors and + should define _VALID_URL as a regexp or a Sequence of regexps, and + re-define the _real_extract() and (optionally) _real_initialize() methods. + + Subclasses may also override suitable() if necessary, but ensure the function + signature is preserved and that this function imports everything it needs + (except other extractors), so that lazy_extractors works correctly. + + Subclasses can define a list of _EMBED_REGEX, which will be searched for in + the HTML of Generic webpages. It may also override _extract_embed_urls + or _extract_from_webpage as necessary. While these are normally classmethods, + _extract_from_webpage is allowed to be an instance method. + + _extract_from_webpage may raise self.StopExtraction() to stop further + processing of the webpage and obtain exclusive rights to it. This is useful + when the extractor cannot reliably be matched using just the URL, + e.g. invidious/peertube instances + + Embed-only extractors can be defined by setting _VALID_URL = False. + + To support username + password (or netrc) login, the extractor must define a + _NETRC_MACHINE and re-define _perform_login(username, password) and + (optionally) _initialize_pre_login() methods. The _perform_login method will + be called between _initialize_pre_login and _real_initialize if credentials + are passed by the user. In cases where it is necessary to have the login + process as part of the extraction rather than initialization, _perform_login + can be left undefined. + + _GEO_BYPASS attribute may be set to False in order to disable + geo restriction bypass mechanisms for a particular extractor. + Though it won't disable explicit geo restriction bypass based on + country code provided with geo_bypass_country. + + _GEO_COUNTRIES attribute may contain a list of presumably geo unrestricted + countries for this extractor.
