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:

|
|
* manifest_url
|
|

|
* ext Will be calculated from URL if missing
|
|
* format A human-readable description of the format

|
|
and format_note fields if missing.
|
|

|
|
("mp4_h264_opus" or "19").

|
|
("3D" or "DASH video")
|
|
* width Width of the video, if known
|
|
* height Height of the video, if known

|
|
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)

|
this field should denote the exact title of the video episode

"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 "title", "description" and "id" 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.
|
|
|
|
Finally, the _WORKING attribute should be set to False for broken IEs
|
|
in order to warn the users and skip the tests.
