class InfoExtractor:
|
||
"""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. 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.
|
||
* 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.

|
||
Each fragment entry must contain either an url
|
||
or a path. If an url is present it should be

|
||
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)

||
* 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.

|
||
This is usefull for additional information that is
|
||
time-consuming to extract. Note that the fields thus

currently allowed to be extracted via this method.
|
||
|

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

|
||
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.
|
||

|
||
"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.
|
||
