class InfoExtractor(object):
|
|
|
"""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:
|
|
|

|
|
|
for plain file media - HTTP URL of this file,

|
|
|

|
|
|
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.

|
|
|
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:

|
|
|
-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
|
|

|
|
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.

a music album:
|
|
|

|
track: Title of the track.
|
|
|
track_number: Number of the track within an album or a disc, as an integer.

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", "description", "uploader",
|
|
|
"uploader_id", "uploader_url", "duration" 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.
|
|
|
|
|
|
|
|
|
A subclass of InfoExtractor must be defined to handle each specific site (or
|
|
|
several sites). Such a concrete subclass should be added to the list of
|
|
|
extractors. It should also:
|
|
|
* define its _VALID_URL attribute as a regexp, or a Sequence of alternative
|
|
|
regexps (but see below)
|
|
|
* re-define the _real_extract() method
|
|
|
* optionally re-define the _real_initialize() method.
|
|
|
|
|
|
An extractor subclass may also override suitable() if necessary, but the
|
|
|
function signature must be preserved and the function must import everything
|
|
|
it needs (except other extractors), so that lazy_extractors works correctly.
|
|
|
If the subclass's suitable() and _real_extract() functions avoid using
|
|
|
_VALID_URL, the subclass need not set that class attribute.
|
|
|
|
|
|
An abstract subclass of InfoExtractor may be used to simplify implementation
|
|
|
within an extractor module; it should not 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.
