The dictionaries must include the following fields:
id: Video identifier.
- url: Final video URL.
title: Video title, unescaped.
- ext: Video filename extension.
- Instead of url and ext, formats can also specified.
+ 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
+ * vcodec Name of the video codec in use
+ * container Name of the container format
+ * filesize The number of bytes, if known in advance
+ * 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", "m3u8" or so.
+ * 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.
+ * quality Order number of the video quality of this
+ format, irrespective of the file format.

+ url: Final video URL.
+ ext: Video filename extension.
+ format: The video format, defaults to ext (used for --get-format)
+ player_url: SWF Player URL (used for rtmpdump).
The following fields are optional:
- format: The video format, defaults to ext (used for --get-format)
+ display_id An alternative identifier for the video, not necessarily
+ unique, but available before title. Typically, id is
+ something like "4234987", title "Dancing naked mole rats",
+ and display_id "dancing-naked-mole-rats"
thumbnails: A list of dictionaries (with the entries "resolution" and
"url") for the varying thumbnails
thumbnail: Full URL to a video thumbnail image.
description: One-line video description.
uploader: Full name of the video uploader.
+ timestamp: UNIX timestamp of the moment the video became available.
upload_date: Video upload date (YYYYMMDD).
+ If not explicitly set, calculated from timestamp.
uploader_id: Nickname or id of the video uploader.
location: Physical location of the video.
- player_url: SWF Player URL (used for rtmpdump).
subtitles: The subtitle file contents as a dictionary in the format
{language: subtitles}.
+ duration: Length of the video in seconds, as an integer.
view_count: How many users have watched the video on the platform.
- urlhandle: [internal] The urlHandle to be used to download the file,
- like returned by urllib.request.urlopen
+ like_count: Number of positive ratings of the video
+ dislike_count: Number of negative ratings of the video
+ comment_count: Number of comments on the video
age_limit: Age restriction for the video, as an integer (years)
- formats: A list of dictionaries for each format available, it must
- be 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")
- * format_note Additional info about the format
- ("3D" or "DASH video")
- * width Width of the video, if known

- * abr Average audio bitrate in KBit/s
- * acodec Name of the audio codec in use
- * vbr Average video bitrate in KBit/s
- * vcodec Name of the video codec in use
- * filesize The number of bytes, if known in advance
webpage_url: The url to the video webpage, if given to youtube-dl it
should allow to get the same result again. (It will be set
by YoutubeDL if it's missing)
_real_extract() methods and define a _VALID_URL regexp.
Probably, they should also be added to the list of extractors.
- _real_extract() must return a *list* of information dictionaries as
- described above.
-
Finally, the _WORKING attribute should be set to False for broken IEs
in order to warn the users and skip the tests.
