"""Information Extractor class.
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.
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.
* 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.
* ext Will be calculated from URL if missing
* format A human-readable description of the format
("mp4 container with h264/opus").
Calculated from the format_id, width, height.
and format_note fields if missing.
* format_id A short description of the format
("mp4_h264_opus" or "19").
Technically optional, but strongly recommended.
* format_note Additional info about the format
("3D" or "DASH video")
* width Width of the video, if known
* height Height of the video, if known
* resolution Textual description of width and height
* tbr Average bitrate of audio and video in KBit/s
* abr Average audio bitrate in KBit/s
* acodec Name of the audio codec in use
* asr Audio sampling rate in Hertz
* vbr Average video bitrate in KBit/s
* fps Frame rate
* vcodec Name of the video codec in use
* container Name of the container format
* filesize The number of bytes, if known in advance
* filesize_approx An estimate for the number of bytes
* player_url SWF Player URL (used for rtmpdump).
* protocol The protocol that will be used for the actual
download, lower-case.
"http", "https", "rtsp", "rtmp", "rtmp_ffmpeg", "rtmpe",
"m3u8", "m3u8_native" or "http_dash_segments".
* fragment_base_url
Base URL for fragments. Each fragment's path
value (if present) will be relative to
this URL.
* fragments A list of fragments of a fragmented media.
Each fragment entry must contain either an url
or a path. If an url is present it should be
considered by a client. Otherwise both path and
fragment_base_url must be present. Here is
the list of all potential fields:
* "url" - fragment's URL
* "path" - fragment's path relative to
fragment_base_url
* "duration" (optional, int or float)
* "filesize" (optional, int)
* 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. Boolean.
* downloader_options A dictionary of downloader options as
described in FileDownloader

entry and one of:
* "data": The subtitles file contents
* "url": A URL pointing to the subtitles file
It can optionally also have:

by YoutubeDL if it's missing)
categories: A list of categories that the video falls in, for example
["Sports", "Berlin"]
tags: A list of tags assigned to the video, e.g. ["sweden", "pop music"]
is_live: True, False, or None (=unknown). Whether this video is a

'private', 'premium_only', 'subscriber_only', 'needs_auth',
'unlisted' or 'public'. Use 'InfoExtractor._availability'
to set it
__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.
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.
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 relevent
attributes with the same semantics as videos (see above).
_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 one should re-define the _real_initialize() and
_real_extract() methods and define a _VALID_URL regexp.
Probably, they should also be added to the list of extractors.
_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.
Finally, the _WORKING attribute should be set to False for broken IEs
in order to warn the users and skip the tests.
