Information extractors are the classes that, given a URL, extract information about the video (or videos) the URL refers to. This information includes the real video URL, the video title, author and others. The information is stored in a dictionary which is then passed to the YoutubeDL. The YoutubeDL processes this information possibly downloading the video to the file system, among other possible outcomes. The type field determines the type of the result. By far the most common value (and the default if _type is missing) is "video", which indicates a single video. For a video, the dictionaries must include the following fields: id: Video identifier. title: Video title, unescaped. Set to an empty string if video has no title as opposed to "None" which signifies that the extractor failed to obtain a title Additionally, it must contain either a formats entry or a url one: formats: A list of dictionaries for each format available, ordered from worst to best quality. Potential fields: * url The mandatory URL representing the media: for plain file media - HTTP URL of this file, for RTMP - RTMP URL, for HLS - URL of the M3U8 media playlist, for HDS - URL of the F4M manifest, for DASH - HTTP URL to plain file media (in case of unfragmented media) - URL of the MPD manifest or base URL representing the media if MPD manifest is parsed from a string (in case of fragmented media) for MSS - URL of the ISM manifest. * request_data Data to send in POST request to the URL * manifest_url The URL of the manifest file in case of fragmented media: for HLS - URL of the M3U8 master playlist, for HDS - URL of the F4M manifest, for DASH - URL of the MPD manifest, for MSS - URL of the ISM manifest. * manifest_stream_number (For internal use only) The index of the stream in the manifest file * ext Will be calculated from URL if missing * format A human-readable description of the format ("mp4 container with h264/opus").

Boolean * preference Order number of this format. If this field is present and not None, the formats get sorted by this field, regardless of all other values. -1 for default (order by other properties), -2 or smaller for less than default. < -1000 to hide the format (if there is another one which is strictly better) * language Language code, e.g. "de" or "en-US". * language_preference Is this in the language mentioned in the URL? 10 if it's what the URL is about, -1 for default (don't know), -10 otherwise, other values reserved for now. * quality Order number of the video quality of this format, irrespective of the file format. -1 for default (order by other properties), -2 or smaller for less than default. * source_preference Order number for this video source (quality takes higher priority) -1 for default (order by other properties), -2 or smaller for less than default. * http_headers A dictionary of additional HTTP headers to add to the request. * stretched_ratio If given and not 1, indicates that the video's pixels are not square. width : height ratio as float. * no_resume The server does not support resuming the (HTTP or RTMP) download.

The following fields are optional: direct: True if a direct video file was given (must only be set by GenericIE) alt_title: A secondary title of the video. display_id An alternative identifier for the video, not necessarily unique, but available before title. Typically, id is something like "4234987", title "Dancing naked mole rats", and display_id "dancing-naked-mole-rats" thumbnails: A list of dictionaries, with the following entries: * "id" (optional, string) - Thumbnail format ID * "url" * "preference" (optional, int) - quality of the image * "width" (optional, int) * "height" (optional, int) * "resolution" (optional, string "{width}x{height}", deprecated) * "filesize" (optional, int) * "http_headers" (dict) - HTTP headers for the request thumbnail: Full URL to a video thumbnail image. description: Full video description. uploader: Full name of the video uploader. license: License name the video is licensed under. creator: The creator of the video. timestamp: UNIX timestamp of the moment the video was uploaded upload_date: Video upload date in UTC (YYYYMMDD). If not explicitly set, calculated from timestamp release_timestamp: UNIX timestamp of the moment the video was released.

If not explicitly set, calculated from release_timestamp modified_timestamp: UNIX timestamp of the moment the video was last modified. modified_date: The date (YYYYMMDD) when the video was last modified in UTC. If not explicitly set, calculated from modified_timestamp uploader_id: Nickname or id of the video uploader. uploader_url: Full URL to a personal webpage of the video uploader. channel: Full name of the channel the video is uploaded on. Note that channel fields may or may not repeat uploader fields. This depends on a particular extractor. channel_id: Id of the channel. channel_url: Full URL to a channel webpage. channel_follower_count: Number of followers of the channel. location: Physical location where the video was filmed. subtitles: The available subtitles as a dictionary in the format {tag: subformats}. "tag" is usually a language code, and "subformats" is a list sorted from lower to higher preference, each element is a dictionary with the "ext" entry and one of: * "data": The subtitles file contents * "url": A URL pointing to the subtitles file It can optionally also have: * "name": Name or description of the subtitles * "http_headers": A dictionary of additional HTTP headers to add to the request. "ext" will be calculated from URL if missing automatic_captions: Like 'subtitles'; contains automatically generated captions instead of normal subtitles duration: Length of the video in seconds, as an integer or float. view_count: How many users have watched the video on the platform. concurrent_view_count: How many users are currently watching the video on the platform. like_count: Number of positive ratings of the video dislike_count: Number of negative ratings of the video repost_count: Number of reposts of the video average_rating: Average rating give by users, the scale used depends on the webpage comment_count: Number of comments on the video comments: A list of comments, each with one or more of the following properties (all but one of text or html optional): * "author" - human-readable name of the comment author * "author_id" - user ID of the comment author * "author_thumbnail" - The thumbnail of the comment author * "id" - Comment ID * "html" - Comment as HTML * "text" - Plain text of the comment * "timestamp" - UNIX timestamp of comment * "parent" - ID of the comment this one is replying to.

Whether this video was originally a live stream. live_status: None (=unknown), 'is_live', 'is_upcoming', 'was_live', 'not_live', or 'post_live' (was live, but VOD is not yet processed) If absent, automatically set from is_live, was_live start_time: Time in seconds where the reproduction should start, as specified in the URL. end_time: Time in seconds where the reproduction should end, as specified in the URL. chapters: A list of dictionaries, with the following entries: * "start_time" - The start time of the chapter in seconds * "end_time" - The end time of the chapter in seconds * "title" (optional, string) playable_in_embed: Whether this video is allowed to play in embedded players on other sites. Can be True (=always allowed), False (=never allowed), None (=unknown), or a string specifying the criteria for embedability; e.g. 'whitelist' availability: Under what condition the video is available. One of 'private', 'premium_only', 'subscriber_only', 'needs_auth', 'unlisted' or 'public'. Use 'InfoExtractor._availability' to set it _old_archive_ids: A list of old archive ids needed for backward compatibility _format_sort_fields: A list of fields to use for sorting formats __post_extractor: A function to be called just before the metadata is written to either disk, logger or console. The function must return a dict which will be added to the info_dict. This is usefull for additional information that is time-consuming to extract. 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. artist: Artist(s) of the track. genre: Genre(s) 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_artist: 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. release_year: Year (YYYY) when the album was released. composer: Composer of the piece 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 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 a _VALID_URL regexp 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. One of these countries will be used by geo restriction bypass mechanism right away in order to bypass geo restriction, of course, if the mechanism is not disabled. _GEO_IP_BLOCKS attribute may contain a list of presumably geo unrestricted IP blocks in CIDR notation for this extractor. One of these IP blocks will be used by geo restriction bypass mechanism similarly to _GEO_COUNTRIES. The _ENABLED attribute should be set to False for IEs that are disabled by default and must be explicitly enabled. The _WORKING attribute should be set to False for broken IEs in order to warn the users and skip the tests.
