Plugins
=======
audio_extract
-------------
Extracts audio from a video file.
:Usage:
.. code-block:: yaml
audio_extract:
codec: "mp3"
quality: 128
``codec``
:expected type: String
:description:
The codec to output after extracting the audio. Supported codecs are aac, flac, mp3, m4a,
opus, vorbis, wav, and best to grab the best possible format at runtime.

Can typically be left undefined to always default to enable. For preset convenience,
this field can be set using an override variable to easily toggle whether this plugin
is enabled or not via Boolean.
``quality``
:expected type: Float
:description:
Optional. Specify ffmpeg audio quality. Insert a value between ``0`` (better) and ``9``
(worse) for variable bitrate, or a specific bitrate like ``128`` for 128k.
----------------------------------------------------------------------------------------------------
chapters
--------
Embeds chapters to video files if they are present. Additional options to add SponsorBlock
chapters and remove specific ones. Can also remove chapters using regex.

.. code-block:: Markdown
A string in the format YYYYMMDD or
(now|today|yesterday|date)[+-][0-9](microsecond|second|minute|hour|day|week|month|year)(s)
Valid examples are ``now-2weeks`` or ``20200101``. Can use override variables in this.
Note that yt-dlp will round times to the closest day, meaning that `day` is the lowest
granularity possible.
:Usage:
.. code-block:: yaml
date_range:
before: "now"
after: "today-2weeks"
``after``

music_tags
----------
Adds tags to every download audio file using
`MediaFile <https://mediafile.readthedocs.io/en/latest/>`_,
the same audio file tagging package used by
`beets <https://beets.readthedocs.io/en/stable/>`_.
It supports basic tags like ``title``, ``album``, ``artist`` and ``albumartist``. You can find
a full list of tags for various file types in MediaFile's
`source code <https://github.com/beetbox/mediafile/blob/v0.9.0/mediafile.py#L1770>`_.
Note that the date fields ``date`` and ``original_date`` expected a standardized date in the
form of YYYY-MM-DD. The variable ``upload_date_standardized`` returns a compatible format.
:Usage:
.. code-block:: yaml
presets:
my_example_preset:
music_tags:

keep_files_before: now
keep_files_after: 19000101
``download_archive_name``
:expected type: Optional[OverridesFormatter]
:description:
The file name to store a subscriptions download archive placed relative to
the output directory. Defaults to ``.ytdl-sub-{subscription_name}-download-archive.json``
``file_name``
:expected type: EntryFormatter
:description:
The file name for the media file. This can include directories such as
``"Season {upload_year}/{title}.{ext}"``, and will be placed in the output directory.
``info_json_name``
:expected type: Optional[EntryFormatter]
:description:
The file name for the media's info json file. This can include directories such
as ``"Season {upload_year}/{title}.{info_json_ext}"``, and will be placed in the output
directory. Can be set to empty string or `null` to disable info json writes.
``keep_files_after``
:expected type: Optional[OverridesFormatter]
:description:
Requires ``maintain_download_archive`` set to True. Uses the same syntax as the
``date_range`` plugin.
Only keeps files that are uploaded after this datetime. By default, ytdl-sub will keep
files after ``19000101``, which implies all files. Can be used in conjunction with
``keep_max_files``.
``keep_files_before``
:expected type: Optional[OverridesFormatter]
:description:
Requires ``maintain_download_archive`` set to True. Uses the same syntax as the
``date_range`` plugin.
Only keeps files that are uploaded before this datetime. By default, ytdl-sub will keep
files before ``now``, which implies all files. Can be used in conjunction with
``keep_max_files``.
``keep_max_files``
:expected type: Optional[OverridesFormatter]
:description:
Requires ``maintain_download_archive`` set to True.
Only keeps N most recently uploaded videos. If set to <= 0, ``keep_max_files`` will not be
applied. Can be used in conjunction with ``keep_files_before`` and ``keep_files_after``.
``maintain_download_archive``
:expected type: Optional[Boolean]
:description:
Maintains a download archive file in the output directory for a subscription.
It is named ``.ytdl-sub-{subscription_name}-download-archive.json``, stored in the
output directory.
The download archive contains a mapping of ytdl IDs to downloaded files. This is used to
create a ytdl download-archive file when invoking a download on a subscription. This will
prevent ytdl from redownloading media already downloaded.
Defaults to False.
``migrated_download_archive_name``
:expected type: Optional[OverridesFormatter]
:description:
Intended to be used if you are migrating a subscription with either a new
subscription name or output directory. It will try to load the archive file using this
name first, and fallback to ``download_archive_name``. It will always save to this file
and remove the original ``download_archive_name``.
``output_directory``
:expected type: OverridesFormatter
:description:
The output directory to store all media files downloaded.
``thumbnail_name``
:expected type: Optional[EntryFormatter]
:description:
The file name for the media's thumbnail image. This can include directories such
as ``"Season {upload_year}/{title}.{thumbnail_ext}"``, and will be placed in the output
directory. Can be set to empty string or `null` to disable thumbnail writes.
----------------------------------------------------------------------------------------------------
overrides
---------
Allows you to define variables that can be used in any EntryFormatter or OverridesFormatter.
:Usage:
.. code-block:: yaml
presets:
my_example_preset:
overrides:
output_directory: "/path/to/media"
custom_file_name: "{upload_date_standardized}.{title_sanitized}"
# Then use the override variables in the output options
output_options:
output_directory: "{output_directory}"
file_name: "{custom_file_name}.{ext}"
thumbnail_name: "{custom_file_name}.{thumbnail_ext}"
Override variables can contain explicit values and other variables, including both override
and source variables.
In addition, any override variable defined will automatically create a ``sanitized`` variable
for use. In the example above, ``output_directory_sanitized`` will exist and perform
sanitization on the value when used.
----------------------------------------------------------------------------------------------------
regex
-----
.. attention::
This plugin will eventually be deprecated and replaced by scripting functions.
You can replicate the example below using the following.
.. code-block:: yaml
# Only includes videos with 'Official Video'
filter_include:
- >-
{ %contains( %lower(title), "official video" ) }
# Excludes videos with '#short' in its description
filter_exclude:
- >-
{ %contains( %lower(description), '#short' ) }
# Creates a capture array with defaults, and assigns
# each capture group to its own variable
overrides:
description_date_capture: >-
{
%regex_capture_many_with_defaults(
description,
[ "([0-9]{4})-([0-9]{2})-([0-9]{2})" ],
[ upload_year, upload_month, upload_day ]
)
}
captured_upload_year: >-
{ %array_at(description_date_capture, 1) }
captured_upload_month: >-
{ %array_at(description_date_capture, 2) }
captured_upload_day: >-
{ %array_at(description_date_capture, 3) }
Performs regex matching on an entry's source or override variables. Regex can be used to filter
entries from proceeding with download or capture groups to create new source variables.
NOTE that YAML differentiates between single-quote (``'``) and double-quote (``"``), which can
affect regex. Double-quote implies string literals, i.e. ``"\n"`` is the literal chars ``\n``,
whereas single-quote, ``'\n'`` gets evaluated to a new line. To escape ``\`` when using
single-quote, use ``\\``. This is necessary if you want your regex to be something like
``\d\n`` to match a number and adjacent new-line. It must be written as ``\\d\n``.
If you want to regex-search multiple source variables to create a logical OR effect, you can
create an override variable that contains the concatenation of them, and search that with regex.
For example, creating the override variable ``"title_and_description": "{title} {description}"``
and using ``title_and_description`` can regex match/exclude from either ``title`` or
``description``.
:Usage:
.. code-block:: yaml
regex:
# By default, if any match fails and has no defaults, the entry will
# be skipped. If False, ytdl-sub will error and stop all downloads
# from proceeding.
skip_if_match_fails: True
from:
# For each entry's `title` value...
title:
# Perform this regex match on it to act as a filter.
# This will only download videos with "[Official Video]" in it. Note that we
# double backslash to make YAML happy
match:
- '\\[Official Video\\]'
# For each entry's `description` value...
description:
# Match with capture groups and defaults.
# This tries to scrape a date from the description and produce new
# source variables
match:
- '([0-9]{4})-([0-9]{2})-([0-9]{2})'
# Exclude any entry where the description contains #short
exclude:
- '#short'
# Each capture group creates these new source variables, respectively,
# as well a sanitized version, i.e. `captured_upload_year_sanitized`
capture_group_names:
- "captured_upload_year"
- "captured_upload_month"
- "captured_upload_day"
# And if the string does not match, use these as respective default
# values for the new source variables.
capture_group_defaults:
- "{upload_year}"
- "{upload_month}"
- "{upload_day}"
``enable``
:expected type: Optional[OverridesFormatter]
:description:
Can typically be left undefined to always default to enable. For preset convenience,
this field can be set using an override variable to easily toggle whether this plugin
is enabled or not via Boolean.
``skip_if_match_fails``
:expected type: Optional[Boolean]
:description:
Defaults to True. If True, when any match fails and has no defaults, the entry will be
skipped. If False, ytdl-sub will error and all downloads will not proceed.
----------------------------------------------------------------------------------------------------
split_by_chapters
-----------------
Splits a file by chapters into multiple files. Each file becomes its own entry with the
new variables
- ``chapter_title``
- ``chapter_index``
- ``chapter_index_padded``
- ``chapter_count``
Note that when using this plugin and performing dry-run, it assumes embedded chapters are being
used with no modifications.
:Usage:
.. code-block:: yaml
split_by_chapters:
when_no_chapters: "pass"
``when_no_chapters``
:expected type: String
:description:
Behavior to perform when no chapters are present. Supports
- "pass" (continue processing),
- "drop" (exclude it from output)
- "error" (stop processing for everything).
If a file has no chapters and is set to "pass", then ``chapter_title`` is
set to the entry's title and ``chapter_index``, ``chapter_count`` are both set to 1.
----------------------------------------------------------------------------------------------------
subtitles
---------
Defines how to download and store subtitles. Using this plugin creates two new variables:
``lang`` and ``subtitles_ext``. ``lang`` is dynamic since you can download multiple subtitles.
It will set the respective language to the correct subtitle file.
:Usage:
.. code-block:: yaml
subtitles:
subtitles_name: "{title_sanitized}.{lang}.{subtitles_ext}"
subtitles_type: "srt"

webm files can only embed "vtt" subtitle types.
``enable``
:expected type: Optional[OverridesFormatter]
:description:
Can typically be left undefined to always default to enable. For preset convenience,
this field can be set using an override variable to easily toggle whether this plugin
is enabled or not via Boolean.
``languages``
:expected type: Optional[List[String]]
:description:
Language code(s) to download for subtitles. Supports a single or list of multiple
language codes. Defaults to only "en".
``subtitles_name``
:expected type: Optional[EntryFormatter]
:description:
The file name for the media's subtitles if they are present. This can include
directories such as ``"Season {upload_year}/{title_sanitized}.{lang}.{subtitles_ext}"``,
and will be placed in the output directory. ``lang`` is dynamic since you can download
multiple subtitles. It will set the respective language to the correct subtitle file.
``subtitles_type``
:expected type: Optional[String]
:description:
Defaults to "srt". One of the subtitle file types "srt", "vtt", "ass", "lrc".
----------------------------------------------------------------------------------------------------
throttle_protection
-------------------
Provides options to make ytdl-sub look more 'human-like' to protect from throttling. For
range-based values, a random number will be chosen within the range to avoid sleeps looking
scripted.

presets:
my_example_preset:
throttle_protection:
sleep_per_download_s:
min: 2.2
max: 10.8
