"""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 Mandatory. The URL of the video file |
|
* 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", "rtmpe", |
|
"m3u8", "m3u8_native" or "http_dash_segments". |
|
* 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. |

|
|
|
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. |
