``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.

``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.


``force_key_frames``

:expected type: Optional[Boolean]
:description:

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. Also note that, considering time zones, it's best
to include a margin of an extra day on either side to be sure it includes the
intended download files.

:Usage:

.. code-block:: yaml

   date_range:
     before: "now"
     after: "today-2weeks"
     breaks: True

: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_files_date_eval``

:expected type: str
:description:
    Uses this standardized date in the form of YYYY-MM-DD to record in the

: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``.

       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.

----------------------------------------------------------------------------------------------------

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.

  set to the entry's title and ``chapter_index``, ``chapter_count`` are both set to 1.


----------------------------------------------------------------------------------------------------

square_thumbnail
----------------
Whether to make thumbnails square. Supports both file and embedded-based thumbnails. Ideal
for representing audio albums.

:Usage:

.. code-block:: yaml

   square_thumbnail: True

----------------------------------------------------------------------------------------------------

static_nfo_tags
---------------
Adds an NFO file for every entry, but does not link it to an entry in the download
archive.  This is intended to produce ``season.nfo`` files in each season
directory. Each entry within a season will overwrite this file with its season
name. If the entry gets deleted from ytdl-sub, this file will remain since it's not
linked.

Usage:

.. code-block:: yaml

   presets:
     my_example_preset:
       static_nfo_tags:
         # required

         nfo_root: "season"
         tags:
           title: "My custom season name!"
         # optional
         kodi_safe: False

``enable``

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"
     embed_subtitles: False
     languages:
       - "en"  # supports multiple languages
       - "de"
     allow_auto_generated_subtitles: False

``allow_auto_generated_subtitles``

:expected type: Optional[Boolean]
:description:
  Defaults to False. Whether to allow auto generated subtitles.


``embed_subtitles``

:expected type: Optional[Boolean]
:description:
  Defaults to False. Whether to embed the subtitles into the video file. Note that
  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".


``languages_required``

:expected type: Optional[List[String]]
:description:
  Language code(s) that are required to be present for downloads to continue. If missing,
  ytdl-sub will throw an error. NOTE: currently this only checks file-based subtitles.


``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.

Range min and max values support static override variables within their definitions.
``sleep_per_download_s`` supports both static and override variables.

:Usage:

.. code-block:: yaml

   presets:
     my_example_preset:
       throttle_protection:
         sleep_per_request_s:
           min: 5.5
           max: 10.4
         sleep_per_download_s:
           min: 2.2
           max: 10.8
         sleep_per_subscription_s:
           min: 9.0
           max: 14.1
         max_downloads_per_subscription:
           min: 10
           max: 36
         subscription_download_probability: 1.0

``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.


``max_downloads_per_subscription``

:expected type: Optional[Range]
:description:
  Number of downloads to perform per subscription.


``sleep_per_download_s``

:expected type: Optional[Range]
:description:
  Number in seconds to sleep between each download. Does not include time it takes for
  ytdl-sub to perform post-processing.


``sleep_per_request_s``

:expected type: Optional[Range]
:description:
  Number in seconds to sleep between each request during metadata download. Note that
  metadata download refers to the initial info.json download, not the actual audio/video
  download for the entry. Also, yt-dlp only supports a single value at this time for this,
  so will always use the max value.


``sleep_per_subscription_s``

:expected type: Optional[Range]
:description:
  Number in seconds to sleep between each subscription.


``subscription_download_probability``

:expected type: Optional[Float]
:description:
  Probability to perform any downloads, recomputed for each subscription. This is only
  recommended to set if you run ytdl-sub in a cron-job, that way you are statistically
  guaranteed over time to eventually download the subscription.


----------------------------------------------------------------------------------------------------

video_tags
----------
Adds tags to every downloaded video file using ffmpeg ``-metadata key=value`` args.

:Usage:

.. code-block:: yaml

   video_tags:
     title: "{title}"
     date: "{upload_date}"
     description: "{description}"

----------------------------------------------------------------------------------------------------

ytdl_options
------------
Allows you to add any ytdl argument to ytdl-sub's downloader.
The argument names can differ slightly from the command-line argument names. See
`this docstring <https://github.com/yt-dlp/yt-dlp/blob/2022.04.08/yt_dlp/YoutubeDL.py#L197>`_
for more details.

:Usage:

.. code-block:: yaml

       presets:
         my_example_preset:
           ytdl_options:
             # Ignore any download related errors and continue
             ignoreerrors: True
             # Stop downloading additional metadata/videos if it
             # exists in your download archive
             break_on_existing: True
             # Path to your YouTube cookies file to download 18+ restricted content
             cookiefile: "/path/to/cookies/file.txt"
             # Only download this number of videos/audio
             max_downloads: 10
             # Download and use English title/description/etc YouTube metadata
             extractor_args:
               youtube:
                 lang:
                   - "en"


where each key is a ytdl argument. Include in the example are some popular ytdl_options.
