# NEW FEATURES

* Based on **youtube-dl 2021.12.17 [commit/6508688](https://github.com/ytdl-org/youtube-dl/commit/6508688e88c83bb811653083db9351702cd39a6a)** ([exceptions](https://github.com/yt-dlp/yt-dlp/issues/21)) and **youtube-dlc 2020.11.11-3 [commit/f9401f2](https://github.com/blackjack4494/yt-dlc/commit/f9401f2a91987068139c5f757b12fc711d4c0cee)**: You get all the features and patches of [youtube-dlc](https://github.com/blackjack4494/yt-dlc) in addition to the latest [youtube-dl](https://github.com/ytdl-org/youtube-dl)

* **[SponsorBlock Integration](#sponsorblock-options)**: You can mark/remove sponsor sections in youtube videos by utilizing the [SponsorBlock](https://sponsor.ajay.app) API

* **[Format Sorting](#sorting-formats)**: The default format sorting options have been changed so that higher resolution and better codecs will be now preferred instead of simply using larger bitrate. Furthermore, you can now specify the sort order using `-S`. This allows for much easier format selection than what is possible by simply using `--format` ([examples](#format-selection-examples))

* **Merged with animelover1984/youtube-dl**: You get most of the features and improvements from [animelover1984/youtube-dl](https://github.com/animelover1984/youtube-dl) including `--write-comments`, `BiliBiliSearch`, `BilibiliChannel`, Embedding thumbnail in mp4/ogg/opus, playlist infojson etc. Note that the NicoNico livestreams are not available. See [#31](https://github.com/yt-dlp/yt-dlp/pull/31) for details.

* **Youtube improvements**:
    * All Feeds (`:ytfav`, `:ytwatchlater`, `:ytsubs`, `:ythistory`, `:ytrec`, `:ytnotif`) and private playlists supports downloading multiple pages of content
    * Search (`ytsearch:`, `ytsearchdate:`), search URLs and in-channel search works
    * Mixes supports downloading multiple pages of content
    * Some (but not all) age-gated content can be downloaded without cookies
    * Fix for [n-sig based throttling](https://github.com/ytdl-org/youtube-dl/issues/29326)
    * Redirect channel's home URL automatically to `/video` to preserve the old behaviour
    * `255kbps` audio is extracted (if available) from youtube music when premium cookies are given
    * Youtube music Albums, channels etc can be downloaded ([except self-uploaded music](https://github.com/yt-dlp/yt-dlp/issues/723))
    * Download livestreams from the start using `--live-from-start` (experimental)

* **Cookies from browser**: Cookies can be automatically extracted from all major web browsers using `--cookies-from-browser BROWSER[+KEYRING][:PROFILE]`

* **Split video by chapters**: Videos can be split into multiple files based on chapters using `--split-chapters`

* **Multi-threaded fragment downloads**: Download multiple fragments of m3u8/mpd videos in parallel. Use `--concurrent-fragments` (`-N`) option to set the number of threads used

* **Aria2c with HLS/DASH**: You can use `aria2c` as the external downloader for DASH(mpd) and HLS(m3u8) formats

* **New and fixed extractors**: Many new extractors have been added and a lot of existing ones have been fixed. See the [changelog](Changelog.md) or the [list of supported sites](supportedsites.md)

* **New MSOs**: Philo, Spectrum, SlingTV, Cablevision, RCN

* **Subtitle extraction from manifests**: Subtitles can be extracted from streaming media manifests. See [commit/be6202f](https://github.com/yt-dlp/yt-dlp/commit/be6202f12b97858b9d716e608394b51065d0419f) for details

* **Multiple paths and output templates**: You can give different [output templates](#output-template) and download paths for different types of files. You can also set a temporary path where intermediary files are downloaded to using `--paths` (`-P`)

* **Portable Configuration**: Configuration files are automatically loaded from the home and root directories. See [configuration](#configuration) for details

* **Output template improvements**: Output templates can now have date-time formatting, numeric offsets, object traversal etc. See [output template](#output-template) for details. Even more advanced operations can also be done with the help of `--parse-metadata` and `--replace-in-metadata`

* **Other new options**: Many new options have been added such as `--concat-playlist`, `--print`, `--wait-for-video`, `--sleep-requests`, `--convert-thumbnails`, `--write-link`, `--force-download-archive`, `--force-overwrites`, `--break-on-reject` etc

* **Improvements**: Regex and other operators in `--format`/`--match-filter`, multiple `--postprocessor-args` and `--downloader-args`, faster archive checking, more [format selection options](#format-selection), merge multi-video/audio, multiple `--config-locations`, `--exec` at different stages, etc

* **Plugins**: Extractors and PostProcessors can be loaded from an external file. See [plugins](#plugins) for details

* **Self-updater**: The releases can be updated using `yt-dlp -U`

See [changelog](Changelog.md) or [commits](https://github.com/yt-dlp/yt-dlp/commits) for the full list of changes

### Differences in default behavior

Some of yt-dlp's default options are different from that of youtube-dl and youtube-dlc:

* The options `--auto-number` (`-A`), `--title` (`-t`) and `--literal` (`-l`), no longer work. See [removed options](#Removed) for details
* `avconv` is not supported as an alternative to `ffmpeg`
* yt-dlp stores config files in slightly different locations to youtube-dl. See [configuration](#configuration) for a list of correct locations
* The default [output template](#output-template) is `%(title)s [%(id)s].%(ext)s`. There is no real reason for this change. This was changed before yt-dlp was ever made public and now there are no plans to change it back to `%(title)s-%(id)s.%(ext)s`. Instead, you may use `--compat-options filename`
* The default [format sorting](#sorting-formats) is different from youtube-dl and prefers higher resolution and better codecs rather than higher bitrates. You can use the `--format-sort` option to change this to any order you prefer, or use `--compat-options format-sort` to use youtube-dl's sorting order
* The default format selector is `bv*+ba/b`. This means that if a combined video + audio format that is better than the best video-only format is found, the former will be preferred. Use `-f bv+ba/b` or `--compat-options format-spec` to revert this
* Unlike youtube-dlc, yt-dlp does not allow merging multiple audio/video streams into one file by default (since this conflicts with the use of `-f bv*+ba`). If needed, this feature must be enabled using `--audio-multistreams` and `--video-multistreams`. You can also use `--compat-options multistreams` to enable both
* `--no-abort-on-error` is enabled by default. Use `--abort-on-error` or `--compat-options abort-on-error` to abort on errors instead
* When writing metadata files such as thumbnails, description or infojson, the same information (if available) is also written for playlists. Use `--no-write-playlist-metafiles` or `--compat-options no-playlist-metafiles` to not write these files
* `--add-metadata` attaches the `infojson` to `mkv` files in addition to writing the metadata when used with `--write-info-json`. Use `--no-embed-info-json` or `--compat-options no-attach-info-json` to revert this
* Some metadata are embedded into different fields when using `--add-metadata` as compared to youtube-dl. Most notably, `comment` field contains the `webpage_url` and `synopsis` contains the `description`. You can [use `--parse-metadata`](#modifying-metadata) to modify this to your liking or use `--compat-options embed-metadata` to revert this
* `playlist_index` behaves differently when used with options like `--playlist-reverse` and `--playlist-items`. See [#302](https://github.com/yt-dlp/yt-dlp/issues/302) for details. You can use `--compat-options playlist-index` if you want to keep the earlier behavior
* The output of `-F` is listed in a new format. Use `--compat-options list-formats` to revert this
* All *experiences* of a funimation episode are considered as a single video. This behavior breaks existing archives. Use `--compat-options seperate-video-versions` to extract information from only the default player
* Youtube live chat (if available) is considered as a subtitle. Use `--sub-langs all,-live_chat` to download all subtitles except live chat. You can also use `--compat-options no-live-chat` to prevent live chat from downloading
* Youtube channel URLs are automatically redirected to `/video`. Append a `/featured` to the URL to download only the videos in the home page. If the channel does not have a videos tab, we try to download the equivalent `UU` playlist instead. For all other tabs, if the channel does not show the requested tab, an error will be raised. Also, `/live` URLs raise an error if there are no live videos instead of silently downloading the entire channel. You may use `--compat-options no-youtube-channel-redirect` to revert all these redirections
* Unavailable videos are also listed for youtube playlists. Use `--compat-options no-youtube-unavailable-videos` to remove this
* If `ffmpeg` is used as the downloader, the downloading and merging of formats happen in a single step when possible. Use `--compat-options no-direct-merge` to revert this
* Thumbnail embedding in `mp4` is done with mutagen if possible. Use `--compat-options embed-thumbnail-atomicparsley` to force the use of AtomicParsley instead
* Some private fields such as filenames are removed by default from the infojson. Use `--no-clean-infojson` or `--compat-options no-clean-infojson` to revert this
* When `--embed-subs` and `--write-subs` are used together, the subtitles are written to disk and also embedded in the media file. You can use just `--embed-subs` to embed the subs and automatically delete the separate file. See [#630 (comment)](https://github.com/yt-dlp/yt-dlp/issues/630#issuecomment-893659460) for more info. `--compat-options no-keep-subs` can be used to revert this
* `certifi` will be used for SSL root certificates, if installed. If you want to use system certificates (e.g. self-signed), use `--compat-options no-certifi`
* youtube-dl tries to remove some superfluous punctuations from filenames. While this can sometimes be helpfull, it is often undesirable. So yt-dlp tries to keep the fields in the filenames as close to their original values as possible. You can use `--compat-options filename-sanitization` to revert to youtube-dl's behavior

For ease of use, a few more compat options are available:
* `--compat-options all`: Use all compat options
* `--compat-options youtube-dl`: Same as `--compat-options all,-multistreams`
* `--compat-options youtube-dlc`: Same as `--compat-options all,-no-live-chat,-no-youtube-channel-redirect`

## DEPENDENCIES
Python versions 3.6+ (CPython and PyPy) are supported. Other versions and implementations may or may not work correctly.

<!-- Python 3.5+ uses VC++14 and it is already embedded in the binary created
<!x-- https://www.microsoft.com/en-us/download/details.aspx?id=26999 --x>
On windows, [Microsoft Visual C++ 2010 SP1 Redistributable Package (x86)](https://download.microsoft.com/download/1/6/5/165255E7-1014-4D0A-B094-B6A430A6BFFC/vcredist_x86.exe) is also necessary to run yt-dlp. You probably already have this, but if the executable throws an error due to missing `MSVCR100.dll` you need to install it manually.
-->

To use or redistribute the dependencies, you must agree to their respective licensing terms.

The Windows and MacOS standalone release binaries are already built with the python interpreter and all optional python packages (marked with \*) included.

<!-- TODO: ffmpeg has merged this patch. Remove this note once there is new release -->
**Note**: There are some regressions in newer ffmpeg versions that causes various issues when used alongside yt-dlp. Since ffmpeg is such an important dependency, we provide [custom builds](https://github.com/yt-dlp/FFmpeg-Builds#ffmpeg-static-auto-builds) with patches for these issues at [yt-dlp/FFmpeg-Builds](https://github.com/yt-dlp/FFmpeg-Builds). See [the readme](https://github.com/yt-dlp/FFmpeg-Builds#patches-applied) for details on the specific issues solved by these builds


## COMPILE

**For Windows**:
To build the Windows executable, you must have pyinstaller (and any of yt-dlp's optional dependencies if needed). Once you have all the necessary dependencies installed, (optionally) build lazy extractors using `devscripts/make_lazy_extractors.py`, and then just run `pyinst.py`. The executable will be built for the same architecture (32/64 bit) as the python used to build it.

    py -m pip install -U pyinstaller -r requirements.txt
    py devscripts/make_lazy_extractors.py
    py pyinst.py

Note that pyinstaller [does not support](https://github.com/pyinstaller/pyinstaller#requirements-and-tested-platforms) Python installed from the Windows store without using a virtual environment

**For Unix**:
You will need the required build tools: `python`, `make` (GNU), `pandoc`, `zip`, `pytest`  
Then simply run `make`. You can also run `make yt-dlp` instead to compile only the binary without updating any of the additional files

**Note**: In either platform, `devscripts/update-version.py` can be used to automatically update the version number

You can also fork the project on github and run your fork's [build workflow](.github/workflows/build.yml) to automatically build a release

                                     warning when guessing). "error" just throws
                                     an error. The default value "fixup_error"
                                     repairs broken URLs, but emits an error if

                                     times, the filter matches if atleast one of
                                     the conditions are met. Eg: --match-filter
                                     !is_live --match-filter "like_count>?100 &

                                     aria2c, avconv, axel, curl, ffmpeg, httpie,
                                     wget (Recommended: aria2c). You can use
                                     this option multiple times to set different
                                     downloaders for different protocols. For
                                     example, --downloader aria2c --downloader
                                     "dash,m3u8:native" will use aria2c for
                                     http/ftp downloads, and the native
                                     downloader for dash/m3u8 downloads (Alias:
                                     --external-downloader)
    --downloader-args NAME:ARGS      Give these arguments to the external
                                     downloader. Specify the downloader name and
                                     the arguments separated by a colon ":". For
                                     ffmpeg, arguments can be passed to
                                     different positions using the same syntax
                                     as --postprocessor-args. You can use this
                                     option multiple times to give different
                                     arguments to different downloaders (Alias:
                                     --external-downloader-args)

                                     values of "WHEN" are the same as that of
                                     --use-postprocessor. Same syntax as the
                                     output template can be used to pass any
                                     field as arguments to the command. After
                                     download, an additional field "filepath"
                                     that contains the final path of the
                                     downloaded file is also available, and if
                                     no fields are passed, %(filepath)q is
                                     appended to the end of the command. This
                                     option can be used multiple times
    --no-exec                        Remove any previously defined --exec
    --convert-subs FORMAT            Convert the subtitles to another format
                                     (currently supported: srt, vtt, ass, lrc)
                                     (Alias: --convert-subtitles)
    --convert-thumbnails FORMAT      Convert the thumbnails to another format
                                     (currently supported: jpg, png, webp)
    --split-chapters                 Split video into multiple files based on
                                     internal chapters. The "chapter:" prefix
                                     can be used with "--paths" and "--output"
                                     to set the output filename for the split
                                     files. See "OUTPUT TEMPLATE" for details
    --no-split-chapters              Do not split video based on chapters
                                     (default)
    --remove-chapters REGEX          Remove chapters whose title matches the
                                     given regular expression. Time ranges
                                     prefixed by a "*" can also be used in place
                                     of chapters to remove the specified range.
                                     Eg: --remove-chapters "*10:15-15:00"
                                     --remove-chapters "intro". This option can
                                     be used multiple times
    --no-remove-chapters             Do not remove any chapters from the file
                                     (default)
    --force-keyframes-at-cuts        Force keyframes around the chapters before
                                     removing/splitting them. Requires a
                                     re-encode and thus is very slow, but the
                                     resulting video may have fewer artifacts
                                     around the cuts
    --no-force-keyframes-at-cuts     Do not force keyframes around the chapters
                                     when cutting/splitting (default)
    --use-postprocessor NAME[:ARGS]  The (case sensitive) name of plugin
                                     postprocessors to be enabled, and
                                     (optionally) arguments to be passed to it,
                                     separated by a colon ":". ARGS are a
                                     semicolon ";" delimited list of NAME=VALUE.
                                     The "when" argument determines when the
                                     postprocessor is invoked. It can be one of
                                     "pre_process" (after video extraction),
                                     "after_filter" (after video passes filter),
                                     "before_dl" (before each video download),
                                     "post_process" (after each video download;
                                     default), "after_move" (after moving video
                                     file to it's final locations),
                                     "after_video" (after downloading and
                                     processing all formats of a video), or
                                     "playlist" (at end of playlist). This
                                     option can be used multiple times to add
                                     different postprocessors

## SponsorBlock Options:
Make chapter entries for, or remove various segments (sponsor,
    introductions, etc.) from downloaded YouTube videos using the
    [SponsorBlock API](https://sponsor.ajay.app)

    --sponsorblock-mark CATS         SponsorBlock categories to create chapters
                                     for, separated by commas. Available
                                     categories are all, default(=all), sponsor,

                                     interaction, music_offtopic, poi_highlight.
                                     You can prefix the category with a "-" to
                                     exempt it. See [1] for description of the
                                     categories. Eg: --sponsorblock-mark all,-preview
                                     [1] https://wiki.sponsor.ajay.app/w/Segment_Categories
    --sponsorblock-remove CATS       SponsorBlock categories to be removed from

                                     remove, remove takes precedence. The syntax
                                     and available categories are the same as
                                     for --sponsorblock-mark except that
                                     "default" refers to "all,-filler" and
                                     poi_highlight is not available
    --sponsorblock-chapter-title TEMPLATE
                                     The title template for SponsorBlock
                                     chapters created by --sponsorblock-mark.
                                     The same syntax as the output template is
                                     used, but the only available fields are
                                     start_time, end_time, category, categories,
                                     name, category_names. Defaults to
                                     "[SponsorBlock]: %(category_names)l"
    --no-sponsorblock                Disable both --sponsorblock-mark and
                                     --sponsorblock-remove
    --sponsorblock-api URL           SponsorBlock API location, defaults to
                                     https://sponsor.ajay.app

                                     (Alias: --no-ignore-dynamic-mpd)
    --ignore-dynamic-mpd             Do not process dynamic DASH manifests
                                     (Alias: --no-allow-dynamic-mpd)
    --hls-split-discontinuity        Split HLS playlists to different formats at
                                     discontinuities such as ad breaks
    --no-hls-split-discontinuity     Do not split HLS playlists to different
                                     formats at discontinuities such as ad
                                     breaks (default)
    --extractor-args KEY:ARGS        Pass these arguments to the extractor. See
                                     "EXTRACTOR ARGUMENTS" for details. You can
                                     use this option multiple times to give
                                     arguments for different extractors

# CONFIGURATION

You can configure yt-dlp by placing any supported command line option to a configuration file. The configuration is loaded from the following locations:

1. **Main Configuration**: The file given by `--config-location`
1. **Portable Configuration**: `yt-dlp.conf` in the same directory as the bundled binary. If you are running from source-code (`<root dir>/yt_dlp/__main__.py`), the root directory is used instead.
1. **Home Configuration**: `yt-dlp.conf` in the home path given by `-P`, or in the current directory if no such path is given
1. **User Configuration**:
    * `%XDG_CONFIG_HOME%/yt-dlp/config` (recommended on Linux/macOS)
    * `%XDG_CONFIG_HOME%/yt-dlp.conf`
    * `%APPDATA%/yt-dlp/config` (recommended on Windows)
    * `%APPDATA%/yt-dlp/config.txt`
    * `~/yt-dlp.conf`
    * `~/yt-dlp.conf.txt`

    `%XDG_CONFIG_HOME%` defaults to `~/.config` if undefined. On windows, `%APPDATA%` generally points to `C:\Users\<user name>\AppData\Roaming` and `~` points to `%HOME%` if present, `%USERPROFILE%` (generally `C:\Users\<user name>`), or `%HOMEDRIVE%%HOMEPATH%`
1. **System Configuration**: `/etc/yt-dlp.conf`

For example, with the following configuration file yt-dlp will always extract the audio, not copy the mtime, use a proxy and save all videos under `YouTube` directory in your home directory:
```
# Lines starting with # are comments

# Always extract audio
-x

# Do not copy the mtime
--no-mtime

# Use this proxy
--proxy 127.0.0.1:3128

# Save all videos under YouTube directory in your home directory
-o ~/YouTube/%(title)s.%(ext)s
```

Note that options in configuration file are just the same options aka switches used in regular command line calls; thus there **must be no whitespace** after `-` or `--`, e.g. `-o` or `--proxy` but not `- o` or `-- proxy`.

You can use `--ignore-config` if you want to disable all configuration files for a particular yt-dlp run. If `--ignore-config` is found inside any configuration file, no further configuration will be loaded. For example, having the option in the portable configuration file prevents loading of home, user, and system configurations. Additionally, (for backward compatibility) if `--ignore-config` is found inside the system configuration file, the user configuration is not loaded.

### Authentication with `.netrc` file

You may also want to configure automatic credentials storage for extractors that support authentication (by providing login and password with `--username` and `--password`) in order not to pass credentials as command line arguments on every yt-dlp execution and prevent tracking plain text passwords in the shell command history. You can achieve this using a [`.netrc` file](https://stackoverflow.com/tags/.netrc/info) on a per extractor basis. For that you will need to create a `.netrc` file in `--netrc-location` and restrict permissions to read/write by only you:
```
touch $HOME/.netrc
chmod a-rwx,u+rw $HOME/.netrc
```
After that you can add credentials for an extractor in the following format, where *extractor* is the name of the extractor in lowercase:
```
machine <extractor> login <username> password <password>
```
For example:
```
machine youtube login myaccount@gmail.com password my_youtube_password
machine twitch login my_twitch_account_name password my_twitch_password
```
To activate authentication with the `.netrc` file you should pass `--netrc` to yt-dlp or place it in the [configuration file](#configuration).

The default location of the .netrc file is `$HOME` (`~`) in UNIX. On Windows, it is `%HOME%` if present, `%USERPROFILE%` (generally `C:\Users\<user name>`) or `%HOMEDRIVE%%HOMEPATH%`

# OUTPUT TEMPLATE

The `-o` option is used to indicate a template for the output file names while `-P` option is used to specify the path each type of file should be saved to.

<!-- MANPAGE: BEGIN EXCLUDED SECTION -->
**tl;dr:** [navigate me to examples](#output-template-examples).
<!-- MANPAGE: END EXCLUDED SECTION -->

The simplest usage of `-o` is not to set any template arguments when downloading a single file, like in `yt-dlp -o funny_video.flv "https://some/video"` (hard-coding file extension like this is _not_ recommended and could break some post-processing).

It may however also contain special sequences that will be replaced when downloading each video. The special sequences may be formatted according to [Python string formatting operations](https://docs.python.org/3/library/stdtypes.html#printf-style-string-formatting). For example, `%(NAME)s` or `%(NAME)05d`. To clarify, that is a percent symbol followed by a name in parentheses, followed by formatting operations.

The field names themselves (the part inside the parenthesis) can also have some special formatting:
1. **Object traversal**: The dictionaries and lists available in metadata can be traversed by using a `.` (dot) separator. You can also do python slicing using `:`. Eg: `%(tags.0)s`, `%(subtitles.en.-1.ext)s`, `%(id.3:7:-1)s`, `%(formats.:.format_id)s`. `%()s` refers to the entire infodict. Note that all the fields that become available using this method are not listed below. Use `-j` to see such fields

1. **Addition**: Addition and subtraction of numeric fields can be done using `+` and `-` respectively. Eg: `%(playlist_index+10)03d`, `%(n_entries+1-playlist_index)d`

1. **Date/time Formatting**: Date/time fields can be formatted according to [strftime formatting](https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes) by specifying it separated from the field name using a `>`. Eg: `%(duration>%H-%M-%S)s`, `%(upload_date>%Y-%m-%d)s`, `%(epoch-3600>%H-%M-%S)s`

1. **Alternatives**: Alternate fields can be specified separated with a `,`. Eg: `%(release_date>%Y,upload_date>%Y|Unknown)s`

1. **Replacement**: A replacement value can specified using a `&` separator. If the field is *not* empty, this replacement value will be used instead of the actual field content. This is done after alternate fields are considered; thus the replacement is used if *any* of the alternative fields is *not* empty.

1. **Default**: A literal default value can be specified for when the field is empty using a `|` separator. This overrides `--output-na-template`. Eg: `%(uploader|Unknown)s`

1. **More Conversions**: In addition to the normal format types `diouxXeEfFgGcrs`, `B`, `j`, `l`, `q`, `D`, `S` can be used for converting to **B**ytes, **j**son (flag `#` for pretty-printing), a comma separated **l**ist (flag `#` for `\n` newline-separated), a string **q**uoted for the terminal (flag `#` to split a list into different arguments), to add **D**ecimal suffixes (Eg: 10M) (flag `#` to use 1024 as factor), and to **S**anitize as filename (flag `#` for restricted), respectively

1. **Unicode normalization**: The format type `U` can be used for NFC [unicode normalization](https://docs.python.org/3/library/unicodedata.html#unicodedata.normalize). The alternate form flag (`#`) changes the normalization to NFD and the conversion flag `+` can be used for NFKC/NFKD compatibility equivalence normalization. Eg: `%(title)+.100U` is NFKC

To summarize, the general syntax for a field is:
```
%(name[.keys][addition][>strf][,alternate][&replacement][|default])[flags][width][.precision][length]type
```

Additionally, you can set different output templates for the various metadata files separately from the general output template by specifying the type of file followed by the template separated by a colon `:`. The different file types supported are `subtitle`, `thumbnail`, `description`, `annotation` (deprecated), `infojson`, `link`, `pl_thumbnail`, `pl_description`, `pl_infojson`, `chapter`, `pl_video`. For example, `-o "%(title)s.%(ext)s" -o "thumbnail:%(title)s\%(title)s.%(ext)s"`  will put the thumbnails in a folder with the same name as the video. If any of the templates is empty, that type of file will not be written. Eg: `--write-thumbnail -o "thumbnail:"` will write thumbnails only for playlists and not for video.

Each aforementioned sequence when referenced in an output template will be replaced by the actual value corresponding to the sequence name. For example for `-o %(title)s-%(id)s.%(ext)s` and an mp4 video with title `yt-dlp test video` and id `BaW_jenozKc`, this will result in a `yt-dlp test video-BaW_jenozKc.mp4` file created in the current directory.

Note that some of the sequences are not guaranteed to be present since they depend on the metadata obtained by a particular extractor. Such sequences will be replaced with placeholder value provided with `--output-na-placeholder` (`NA` by default).

**Tip**: Look at the `-j` output to identify which fields are available for the particular URL

For numeric sequences you can use [numeric related formatting](https://docs.python.org/3/library/stdtypes.html#printf-style-string-formatting), for example, `%(view_count)05d` will result in a string with view count padded with zeros up to 5 characters, like in `00042`.

Output templates can also contain arbitrary hierarchical path, e.g. `-o "%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s"` which will result in downloading each video in a directory corresponding to this path template. Any missing directory will be automatically created for you.

To use percent literals in an output template use `%%`. To output to stdout use `-o -`.

The current default template is `%(title)s [%(id)s].%(ext)s`.

In some cases, you don't want special characters such as 中, spaces, or &, such as when transferring the downloaded filename to a Windows system or the filename through an 8bit-unsafe channel. In these cases, add the `--restrict-filenames` flag to get a shorter title.

<!-- MANPAGE: BEGIN EXCLUDED SECTION -->
#### Output template and Windows batch files

If you are using an output template inside a Windows batch file then you must escape plain percent characters (`%`) by doubling, so that `-o "%(title)s-%(id)s.%(ext)s"` should become `-o "%%(title)s-%%(id)s.%%(ext)s"`. However you should not touch `%`'s that are not plain characters, e.g. environment variables for expansion should stay intact: `-o "C:\%HOMEPATH%\Desktop\%%(title)s.%%(ext)s"`.

# Stream the video being downloaded to stdout
$ yt-dlp -o - BaW_jenozKc
```

# FORMAT SELECTION

By default, yt-dlp tries to download the best available quality if you **don't** pass any options.
This is generally equivalent to using `-f bestvideo*+bestaudio/best`. However, if multiple audiostreams is enabled (`--audio-multistreams`), the default format changes to `-f bestvideo+bestaudio/best`. Similarly, if ffmpeg is unavailable, or if you use yt-dlp to stream to `stdout` (`-o -`), the default becomes `-f best/bestvideo+bestaudio`.

**Deprecation warning**: Latest versions of yt-dlp can stream multiple formats to the stdout simultaneously using ffmpeg. So, in future versions, the default for this will be set to `-f bv*+ba/b` similar to normal downloads. If you want to preserve the `-f b/bv+ba` setting, it is recommended to explicitly specify it in the configuration options.

The general syntax for format selection is `-f FORMAT` (or `--format FORMAT`) where `FORMAT` is a *selector expression*, i.e. an expression that describes format or formats you would like to download.

<!-- MANPAGE: BEGIN EXCLUDED SECTION -->
**tl;dr:** [navigate me to examples](#format-selection-examples).
<!-- MANPAGE: END EXCLUDED SECTION -->

The simplest case is requesting a specific format, for example with `-f 22` you can download the format with format code equal to 22. You can get the list of available format codes for particular video using `--list-formats` or `-F`. Note that these format codes are extractor specific.

You can also use a file extension (currently `3gp`, `aac`, `flv`, `m4a`, `mp3`, `mp4`, `ogg`, `wav`, `webm` are supported) to download the best quality format of a particular file extension served as a single file, e.g. `-f webm` will download the best quality format with the `webm` extension served as a single file.

You can use `-f -` to interactively provide the format selector *for each video*

You can also use special names to select particular edge case formats:

 - `all`: Select **all formats** separately
 - `mergeall`: Select and **merge all formats** (Must be used with `--audio-multistreams`, `--video-multistreams` or both)
 - `b*`, `best*`: Select the best quality format that **contains either** a video or an audio
 - `b`, `best`: Select the best quality format that **contains both** video and audio. Equivalent to `best*[vcodec!=none][acodec!=none]`
 - `bv`, `bestvideo`: Select the best quality **video-only** format. Equivalent to `best*[acodec=none]`
 - `bv*`, `bestvideo*`: Select the best quality format that **contains video**. It may also contain audio. Equivalent to `best*[vcodec!=none]`
 - `ba`, `bestaudio`: Select the best quality **audio-only** format. Equivalent to `best*[vcodec=none]`
 - `ba*`, `bestaudio*`: Select the best quality format that **contains audio**. It may also contain video. Equivalent to `best*[acodec!=none]` ([Do not use!](https://github.com/yt-dlp/yt-dlp/issues/979#issuecomment-919629354))
 - `w*`, `worst*`: Select the worst quality format that contains either a video or an audio
 - `w`, `worst`: Select the worst quality format that contains both video and audio. Equivalent to `worst*[vcodec!=none][acodec!=none]`
 - `wv`, `worstvideo`: Select the worst quality video-only format. Equivalent to `worst*[acodec=none]`
 - `wv*`, `worstvideo*`: Select the worst quality format that contains video. It may also contain audio. Equivalent to `worst*[vcodec!=none]`
 - `wa`, `worstaudio`: Select the worst quality audio-only format. Equivalent to `worst*[vcodec=none]`
 - `wa*`, `worstaudio*`: Select the worst quality format that contains audio. It may also contain video. Equivalent to `worst*[acodec!=none]`

For example, to download the worst quality video-only format you can use `-f worstvideo`. It is however recommended not to use `worst` and related options. When your format selector is `worst`, the format which is worst in all respects is selected. Most of the time, what you actually want is the video with the smallest filesize instead. So it is generally better to use `-S +size` or more rigorously, `-S +size,+br,+res,+fps` instead of `-f worst`. See [sorting formats](#sorting-formats) for more details.

You can select the n'th best format of a type by using `best<type>.<n>`. For example, `best.2` will select the 2nd best combined format. Similarly, `bv*.3` will select the 3rd best format that contains a video stream.

If you want to download multiple videos and they don't have the same formats available, you can specify the order of preference using slashes. Note that formats on the left hand side are preferred, for example `-f 22/17/18` will download format 22 if it's available, otherwise it will download format 17 if it's available, otherwise it will download format 18 if it's available, otherwise it will complain that no suitable formats are available for download.

If you want to download several formats of the same video use a comma as a separator, e.g. `-f 22,17,18` will download all these three formats, of course if they are available. Or a more sophisticated example combined with the precedence feature: `-f 136/137/mp4/bestvideo,140/m4a/bestaudio`.

You can merge the video and audio of multiple formats into a single file using `-f <format1>+<format2>+...` (requires ffmpeg installed), for example `-f bestvideo+bestaudio` will download the best video-only format, the best audio-only format and mux them together with ffmpeg.

**Deprecation warning**: Since the *below* described behavior is complex and counter-intuitive, this will be removed and multistreams will be enabled by default in the future. A new operator will be instead added to limit formats to single audio/video

Unless `--video-multistreams` is used, all formats with a video stream except the first one are ignored. Similarly, unless `--audio-multistreams` is used, all formats with an audio stream except the first one are ignored. For example, `-f bestvideo+best+bestaudio --video-multistreams --audio-multistreams` will download and merge all 3 given formats. The resulting file will have 2 video streams and 2 audio streams. But `-f bestvideo+best+bestaudio --no-video-multistreams` will download and merge only `bestvideo` and `bestaudio`. `best` is ignored since another format containing a video stream (`bestvideo`) has already been selected. The order of the formats is therefore important. `-f best+bestaudio --no-audio-multistreams` will download and merge both formats while `-f bestaudio+best --no-audio-multistreams` will ignore `best` and download only `bestaudio`.

## Filtering Formats

You can also filter the video formats by putting a condition in brackets, as in `-f "best[height=720]"` (or `-f "[filesize>10M]"`).

The following numeric meta fields can be used with comparisons `<`, `<=`, `>`, `>=`, `=` (equals), `!=` (not equals):

 - `filesize`: The number of bytes, if known in advance
 - `width`: Width of the video, if known
 - `height`: Height of the video, if known
 - `tbr`: Average bitrate of audio and video in KBit/s
 - `abr`: Average audio bitrate in KBit/s
 - `vbr`: Average video bitrate in KBit/s
 - `asr`: Audio sampling rate in Hertz
 - `fps`: Frame rate

Also filtering work for comparisons `=` (equals), `^=` (starts with), `$=` (ends with), `*=` (contains), `~=` (matches regex) and following string meta fields:

 - `ext`: File extension
 - `acodec`: Name of the audio codec in use
 - `vcodec`: Name of the video codec in use
 - `container`: Name of the container format
 - `protocol`: The protocol that will be used for the actual download, lower-case (`http`, `https`, `rtsp`, `rtmp`, `rtmpe`, `mms`, `f4m`, `ism`, `http_dash_segments`, `m3u8`, or `m3u8_native`)
 - `format_id`: A short description of the format
 - `language`: Language code

Any string comparison may be prefixed with negation `!` in order to produce an opposite comparison, e.g. `!*=` (does not contain). The comparand of a string comparison needs to be quoted with either double or single quotes if it contains spaces or special characters other than `._-`.

Note that none of the aforementioned meta fields are guaranteed to be present since this solely depends on the metadata obtained by particular extractor, i.e. the metadata offered by the website. Any other field made available by the extractor can also be used for filtering.

Formats for which the value is not known are excluded unless you put a question mark (`?`) after the operator. You can combine format filters, so `-f "[height<=?720][tbr>500]"` selects up to 720p videos (or videos where the height is not known) with a bitrate of at least 500 KBit/s. You can also use the filters with `all` to download all formats that satisfy the filter. For example, `-f "all[vcodec=none]"` selects all audio-only formats.

Format selectors can also be grouped using parentheses, for example if you want to download the best pre-merged mp4 and webm formats with a height lower than 480 you can use `-f "(mp4,webm)[height<480]"`.

## Sorting Formats

You can change the criteria for being considered the `best` by using `-S` (`--format-sort`). The general format for this is `--format-sort field1,field2...`.

The available fields are:

 - `hasvid`: Gives priority to formats that has a video stream
 - `hasaud`: Gives priority to formats that has a audio stream
 - `ie_pref`: The format preference
 - `lang`: The language preference
 - `quality`: The quality of the format
 - `source`: The preference of the source
 - `proto`: Protocol used for download (`https`/`ftps` > `http`/`ftp` > `m3u8_native`/`m3u8` > `http_dash_segments`> `websocket_frag` > `mms`/`rtsp` > `f4f`/`f4m`)
 - `vcodec`: Video Codec (`av01` > `vp9.2` > `vp9` > `h265` > `h264` > `vp8` > `h263` > `theora` > other)
 - `acodec`: Audio Codec (`flac`/`alac` > `wav`/`aiff` > `opus` > `vorbis` > `aac` > `mp4a` > `mp3` > `eac3` > `ac3` > `dts` > other)
 - `codec`: Equivalent to `vcodec,acodec`
 - `vext`: Video Extension (`mp4` > `webm` > `flv` > other). If `--prefer-free-formats` is used, `webm` is preferred.
 - `aext`: Audio Extension (`m4a` > `aac` > `mp3` > `ogg` > `opus` > `webm` > other). If `--prefer-free-formats` is used, the order changes to `opus` > `ogg` > `webm` > `m4a` > `mp3` > `aac`.
 - `ext`: Equivalent to `vext,aext`
 - `filesize`: Exact filesize, if known in advance
 - `fs_approx`: Approximate filesize calculated from the manifests
 - `size`: Exact filesize if available, otherwise approximate filesize
 - `height`: Height of video
 - `width`: Width of video
 - `res`: Video resolution, calculated as the smallest dimension.
 - `fps`: Framerate of video
 - `hdr`: The dynamic range of the video (`DV` > `HDR12` > `HDR10+` > `HDR10` > `HLG` > `SDR`)
 - `tbr`: Total average bitrate in KBit/s
 - `vbr`: Average video bitrate in KBit/s
 - `abr`: Average audio bitrate in KBit/s
 - `br`: Equivalent to using `tbr,vbr,abr`
 - `asr`: Audio sample rate in Hz
 
**Deprecation warning**: Many of these fields have (currently undocumented) aliases, that may be removed in a future version. It is recommended to use only the documented field names.

All fields, unless specified otherwise, are sorted in descending order. To reverse this, prefix the field with a `+`. Eg: `+res` prefers format with the smallest resolution. Additionally, you can suffix a preferred value for the fields, separated by a `:`. Eg: `res:720` prefers larger videos, but no larger than 720p and the smallest video if there are no videos less than 720p. For `codec` and `ext`, you can provide two preferred values, the first for video and the second for audio. Eg: `+codec:avc:m4a` (equivalent to `+vcodec:avc,+acodec:m4a`) sets the video codec preference to `h264` > `h265` > `vp9` > `vp9.2` > `av01` > `vp8` > `h263` > `theora` and audio codec preference to `mp4a` > `aac` > `vorbis` > `opus` > `mp3` > `ac3` > `dts`. You can also make the sorting prefer the nearest values to the provided by using `~` as the delimiter. Eg: `filesize~1G` prefers the format with filesize closest to 1 GiB.

The fields `hasvid` and `ie_pref` are always given highest priority in sorting, irrespective of the user-defined order. This behaviour can be changed by using `--format-sort-force`. Apart from these, the default order used is: `lang,quality,res,fps,hdr:12,codec:vp9.2,size,br,asr,proto,ext,hasaud,source,id`. The extractors may override this default order, but they cannot override the user-provided order.

Note that the default has `codec:vp9.2`; i.e. `av1` is not preferred. Similarly, the default for hdr is `hdr:12`; i.e. dolby vision is not preferred. These choices are made since DV and AV1 formats are not yet fully compatible with most devices. This may be changed in the future as more devices become capable of smoothly playing back these formats.

If your format selector is `worst`, the last item is selected after sorting. This means it will select the format that is worst in all respects. Most of the time, what you actually want is the video with the smallest filesize instead. So it is generally better to use `-f best -S +size,+br,+res,+fps`.

**Tip**: You can use the `-v -F` to see how the formats have been sorted (worst to best).

## Format Selection examples

```bash
# Download and merge the best video-only format and the best audio-only format,
# or download the best combined format if video-only format is not available
$ yt-dlp -f "bv+ba/b"

# Download best format that contains video,
# and if it doesn't already have an audio stream, merge it with best audio-only format
$ yt-dlp -f "bv*+ba/b"

# Same as above
$ yt-dlp

# Download the best video-only format and the best audio-only format without merging them
# For this case, an output template should be used since
# by default, bestvideo and bestaudio will have the same file name.
$ yt-dlp -f "bv,ba" -o "%(title)s.f%(format_id)s.%(ext)s"

# Download and merge the best format that has a video stream,
# and all audio-only formats into one file
$ yt-dlp -f "bv*+mergeall[vcodec=none]" --audio-multistreams

# Download and merge the best format that has a video stream,
# and the best 2 audio-only formats into one file
$ yt-dlp -f "bv*+ba+ba.2" --audio-multistreams


# The following examples show the old method (without -S) of format selection
# and how to use -S to achieve a similar but (generally) better result

# Download the worst video available (old method)
$ yt-dlp -f "wv*+wa/w"

# Download the best video available but with the smallest resolution
$ yt-dlp -S "+res"

# Download the smallest video available
$ yt-dlp -S "+size,+br"


# Download the best mp4 video available, or the best video if no mp4 available
$ yt-dlp -f "bv*[ext=mp4]+ba[ext=m4a]/b[ext=mp4] / bv*+ba/b"

# Download the best video with the best extension
# (For video, mp4 > webm > flv. For audio, m4a > aac > mp3 ...)
$ yt-dlp -S "ext"


# Download the best video available but no better than 480p,
# or the worst video if there is no video under 480p
$ yt-dlp -f "bv*[height<=480]+ba/b[height<=480] / wv*+ba/w"

# Download the best video available with the largest height but no better than 480p,
# or the best video with the smallest resolution if there is no video under 480p
$ yt-dlp -S "height:480"

# Download the best video available with the largest resolution but no better than 480p,
# or the best video with the smallest resolution if there is no video under 480p
# Resolution is determined by using the smallest dimension.
# So this works correctly for vertical videos as well
$ yt-dlp -S "res:480"


# Download the best video (that also has audio) but no bigger than 50 MB,
# or the worst video (that also has audio) if there is no video under 50 MB
$ yt-dlp -f "b[filesize<50M] / w"

# Download largest video (that also has audio) but no bigger than 50 MB,
# or the smallest video (that also has audio) if there is no video under 50 MB
$ yt-dlp -f "b" -S "filesize:50M"

# Download best video (that also has audio) that is closest in size to 50 MB
$ yt-dlp -f "b" -S "filesize~50M"


# Download best video available via direct link over HTTP/HTTPS protocol,
# or the best video available via any protocol if there is no such video
$ yt-dlp -f "(bv*+ba/b)[protocol^=http][protocol!*=dash] / (bv*+ba/b)"

# Download best video available via the best protocol
# (https/ftps > http/ftp > m3u8_native > m3u8 > http_dash_segments ...)
$ yt-dlp -S "proto"


# Download the best video with either h264 or h265 codec,
# or the best video if there is no such video
$ yt-dlp -f "(bv*[vcodec~='^((he|a)vc|h26[45])']+ba) / (bv*+ba/b)"

# Download the best video with best codec no better than h264,
# or the best video with worst codec if there is no such video
$ yt-dlp -S "codec:h264"

# Download the best video with worst codec no worse than h264,
# or the best video with best codec if there is no such video
$ yt-dlp -S "+codec:h264"


# More complex examples

# Download the best video no better than 720p preferring framerate greater than 30,
# or the worst video (still preferring framerate greater than 30) if there is no such video
$ yt-dlp -f "((bv*[fps>30]/bv*)[height<=720]/(wv*[fps>30]/wv*)) + ba / (b[fps>30]/b)[height<=720]/(w[fps>30]/w)"

# Download the video with the largest resolution no better than 720p,
# or the video with the smallest resolution available if there is no such video,
# preferring larger framerate for formats with the same resolution
$ yt-dlp -S "res:720,fps"


# Download the video with smallest resolution no worse than 480p,
# or the video with the largest resolution available if there is no such video,
# preferring better codec and then larger total bitrate for the same resolution
$ yt-dlp -S "+res:480,codec,br"
```

# MODIFYING METADATA

The metadata obtained by the extractors can be modified by using `--parse-metadata` and `--replace-in-metadata`

`--replace-in-metadata FIELDS REGEX REPLACE` is used to replace text in any metadata field using [python regular expression](https://docs.python.org/3/library/re.html#regular-expression-syntax). [Backreferences](https://docs.python.org/3/library/re.html?highlight=backreferences#re.sub) can be used in the replace string for advanced use.

The general syntax of `--parse-metadata FROM:TO` is to give the name of a field or an [output template](#output-template) to extract data from, and the format to interpret it as, separated by a colon `:`. Either a [python regular expression](https://docs.python.org/3/library/re.html#regular-expression-syntax) with named capture groups or a similar syntax to the [output template](#output-template) (only `%(field)s` formatting is supported) can be used for `TO`. The option can be used multiple times to parse and modify various fields.

Note that any field created by this can be used in the [output template](#output-template) and will also affect the media file's metadata added when using `--add-metadata`.

This option also has a few special uses:
* You can download an additional URL based on the metadata of the currently downloaded video. To do this, set the field `additional_urls` to the URL that you want to download. Eg: `--parse-metadata "description:(?P<additional_urls>https?://www\.vimeo\.com/\d+)` will download the first vimeo video found in the description
* You can use this to change the metadata that is embedded in the media file. To do this, set the value of the corresponding field with a `meta_` prefix. For example, any value you set to `meta_description` field will be added to the `description` field in the file. For example, you can use this to set a different "description" and "synopsis". To modify the metadata of individual streams, use the `meta<n>_` prefix (Eg: `meta1_language`). Any value set to the `meta_` field will overwrite all default values.

**Note**: Metadata modification happens before format selection, post-extraction and other post-processing operations. Some fields may be added or changed during these steps, overriding your changes.

For reference, these are the fields yt-dlp adds by default to the file metadata:

Metadata fields            | From
:--------------------------|:------------------------------------------------
`title`                    | `track` or `title`
`date`                     | `upload_date`
`description`,  `synopsis` | `description`
`purl`, `comment`          | `webpage_url`
`track`                    | `track_number`
`artist`                   | `artist`, `creator`, `uploader` or `uploader_id`
`genre`                    | `genre`
`album`                    | `album`
`album_artist`             | `album_artist`
`disc`                     | `disc_number`
`show`                     | `series`
`season_number`            | `season_number`
`episode_id`               | `episode` or `episode_id`
`episode_sort`             | `episode_number`
`language` of each stream  | the format's `language`

**Note**: The file format may not support some of these fields


## Modifying metadata examples

```bash
# Interpret the title as "Artist - Title"
$ yt-dlp --parse-metadata "title:%(artist)s - %(title)s"

# Regex example
$ yt-dlp --parse-metadata "description:Artist - (?P<artist>.+)"

# Set title as "Series name S01E05"
$ yt-dlp --parse-metadata "%(series)s S%(season_number)02dE%(episode_number)02d:%(title)s"

# Prioritize uploader as the "artist" field in video metadata
$ yt-dlp --parse-metadata "%(uploader|)s:%(meta_artist)s" --add-metadata

# Set "comment" field in video metadata using description instead of webpage_url,
# handling multiple lines correctly
$ yt-dlp --parse-metadata "description:(?s)(?P<meta_comment>.+)" --add-metadata

# Remove "formats" field from the infojson by setting it to an empty string
$ yt-dlp --parse-metadata ":(?P<formats>)" -j

# Replace all spaces and "_" in title and uploader with a `-`
$ yt-dlp --replace-in-metadata "title,uploader" "[ _]" "-"

```

# EXTRACTOR ARGUMENTS

Some extractors accept additional arguments which can be passed using `--extractor-args KEY:ARGS`. `ARGS` is a `;` (semicolon) separated string of `ARG=VAL1,VAL2`. Eg: `--extractor-args "youtube:player-client=android_embedded,web;include_live_dash" --extractor-args "funimation:version=uncut"`

The following extractors use this feature:

#### youtube
* `skip`: One or more of `hls`, `dash` or `translated_subs` to skip extraction of the m3u8 manifests, dash manifests and auto-translated subtitles respectively
* `player_client`: Clients to extract video data from. The main clients are `web`, `android` and `ios` with variants `_music`, `_embedded`, `_embedscreen`, `_creator` (Eg: `web_embedded`); and `mweb` and `tv_embedded` (agegate bypass) with no variants. By default, `android,web` is used, but tv_embedded and creator variants are added as required for age-gated videos. Similarly the music variants are added for `music.youtube.com` urls. You can use `all` to use all the clients, and `default` for the default clients.
* `player_skip`: Skip some network requests that are generally needed for robust extraction. One or more of `configs` (skip client configs), `webpage` (skip initial webpage), `js` (skip js player). While these options can help reduce the number of requests needed or avoid some rate-limiting, they could cause some issues. See [#860](https://github.com/yt-dlp/yt-dlp/pull/860) for more details
* `include_live_dash`: Include live dash formats even without `--live-from-start` (These formats don't download properly)
* `comment_sort`: `top` or `new` (default) - choose comment sorting mode (on YouTube's side)
* `max_comments`: Limit the amount of comments to gather. Comma-separated list of integers representing `max-comments,max-parents,max-replies,max-replies-per-thread`. Default is `all,all,all,all`
    * E.g. `all,all,1000,10` will get a maximum of 1000 replies total, with up to 10 replies per thread. `1000,all,100` will get a maximum of 1000 comments, with a maximum of 100 replies total

#### youtubetab (YouTube playlists, channels, feeds, etc.)
* `skip`: One or more of `webpage` (skip initial webpage download), `authcheck` (allow the download of playlists requiring authentication when no initial webpage is downloaded. This may cause unwanted behavior, see [#1122](https://github.com/yt-dlp/yt-dlp/pull/1122) for more details)
* `approximate_date`: Extract approximate `upload_date` in flat-playlist. This may cause date-based filters to be slightly off

#### funimation
* `language`: Languages to extract. Eg: `funimation:language=english,japanese`
* `version`: The video version to extract - `uncut` or `simulcast`

#### crunchyroll
* `language`: Languages to extract. Eg: `crunchyroll:language=jaJp`
* `hardsub`: Which hard-sub versions to extract. Eg: `crunchyroll:hardsub=None,enUS`

#### crunchyrollbeta
* `format`: Which stream type(s) to extract. Default is `adaptive_hls` Eg: `crunchyrollbeta:format=vo_adaptive_hls`
    * Potentially useful values include `adaptive_hls`, `adaptive_dash`, `vo_adaptive_hls`, `vo_adaptive_dash`, `download_hls`, `trailer_hls`, `trailer_dash`
* `hardsub`: Preference order for which hardsub versions to extract. Default is `None` (no hardsubs). Eg: `crunchyrollbeta:hardsub=en-US,None`

#### vikichannel
* `video_types`: Types of videos to download - one or more of `episodes`, `movies`, `clips`, `trailers`

#### niconico
* `segment_duration`: Segment duration in milliseconds for HLS-DMC formats. Use it at your own risk since this feature **may result in your account termination.**

#### youtubewebarchive
* `check_all`: Try to check more at the cost of more requests. One or more of `thumbnails`, `captures`

#### gamejolt
* `comment_sort`: `hot` (default), `you` (cookies needed), `top`, `new` - choose comment sorting mode (on GameJolt's side)

#### hotstar
* `res`: resolution to ignore - one or more of `sd`, `hd`, `fhd`
* `vcodec`: vcodec to ignore - one or more of `h264`, `h265`, `dvh265`
* `dr`: dynamic range to ignore - one or more of `sdr`, `hdr10`, `dv`

#### tiktok
* `app_version`: App version to call mobile APIs with - should be set along with `manifest_app_version`. (e.g. `20.2.1`)
* `manifest_app_version`: Numeric app version to call mobile APIs with. (e.g. `221`)

#### rokfinchannel
* `tab`: Which tab to download. One of `new`, `top`, `videos`, `podcasts`, `streams`, `stacks`. (E.g. `rokfinchannel:tab=streams`)


NOTE: These options may be changed/removed in the future without concern for backward compatibility

# PLUGINS

Plugins are loaded from `<root-dir>/ytdlp_plugins/<type>/__init__.py`; where `<root-dir>` is the directory of the binary (`<root-dir>/yt-dlp`), or the root directory of the module if you are running directly from source-code (`<root dir>/yt_dlp/__main__.py`). Plugins are currently not supported for the `pip` version

Plugins can be of `<type>`s `extractor` or `postprocessor`. Extractor plugins do not need to be enabled from the CLI and are automatically invoked when the input URL is suitable for it. Postprocessor plugins can be invoked using `--use-postprocessor NAME`.

See [ytdlp_plugins](ytdlp_plugins) for example plugins.

Note that **all** plugins are imported even if not invoked, and that **there are no checks** performed on plugin code. Use plugins at your own risk and only if you trust the code

If you are a plugin author, add [ytdlp-plugins](https://github.com/topics/ytdlp-plugins) as a topic to your repository for discoverability


# EMBEDDING YT-DLP

yt-dlp makes the best effort to be a good command-line program, and thus should be callable from any programming language.

Your program should avoid parsing the normal stdout since they may change in future versions. Instead they should use options such as `-J`, `--print`, `--progress-template`, `--exec` etc to create console output that you can reliably reproduce and parse.

From a Python program, you can embed yt-dlp in a more powerful fashion, like this:

```python
from yt_dlp import YoutubeDL

ydl_opts = {'format': 'bestaudio'}
with YoutubeDL(ydl_opts) as ydl:
    ydl.download(['https://www.youtube.com/watch?v=BaW_jenozKc'])
```

Most likely, you'll want to use various options. For a list of options available, have a look at [`yt_dlp/YoutubeDL.py`](yt_dlp/YoutubeDL.py#L181).

Here's a more complete example demonstrating various functionality:

```python
import json
import yt_dlp


class MyLogger:
    def debug(self, msg):
        # For compatibility with youtube-dl, both debug and info are passed into debug
        # You can distinguish them by the prefix '[debug] '
        if msg.startswith('[debug] '):
            pass
        else:
            self.info(msg)

    def info(self, msg):
        pass

    def warning(self, msg):
        pass

    def error(self, msg):
        print(msg)


# ℹ️ See the docstring of yt_dlp.postprocessor.common.PostProcessor
class MyCustomPP(yt_dlp.postprocessor.PostProcessor):
    # ℹ️ See docstring of yt_dlp.postprocessor.common.PostProcessor.run
    def run(self, info):
        self.to_screen('Doing stuff')
        return [], info


# ℹ️ See "progress_hooks" in the docstring of yt_dlp.YoutubeDL
def my_hook(d):
    if d['status'] == 'finished':
        print('Done downloading, now converting ...')


def format_selector(ctx):
    """ Select the best video and the best audio that won't result in an mkv.
    This is just an example and does not handle all cases """

    # formats are already sorted worst to best
    formats = ctx.get('formats')[::-1]

    # acodec='none' means there is no audio
    best_video = next(f for f in formats
                      if f['vcodec'] != 'none' and f['acodec'] == 'none')

    # find compatible audio extension
    audio_ext = {'mp4': 'm4a', 'webm': 'webm'}[best_video['ext']]
    # vcodec='none' means there is no video
    best_audio = next(f for f in formats if (
        f['acodec'] != 'none' and f['vcodec'] == 'none' and f['ext'] == audio_ext))

    yield {
        # These are the minimum required fields for a merged format
        'format_id': f'{best_video["format_id"]}+{best_audio["format_id"]}',
        'ext': best_video['ext'],
        'requested_formats': [best_video, best_audio],
        # Must be + separated list of protocols
        'protocol': f'{best_video["protocol"]}+{best_audio["protocol"]}'
    }


# ℹ️ See docstring of yt_dlp.YoutubeDL for a description of the options
ydl_opts = {
    'format': format_selector,
    'postprocessors': [{
        # Embed metadata in video using ffmpeg.
        # ℹ️ See yt_dlp.postprocessor.FFmpegMetadataPP for the arguments it accepts
        'key': 'FFmpegMetadata',
        'add_chapters': True,
        'add_metadata': True,
    }],
    'logger': MyLogger(),
    'progress_hooks': [my_hook],
    # Add custom headers
    'http_headers': {'Referer': 'https://www.google.com'}
}


# ℹ️ See the public functions in yt_dlp.YoutubeDL for for other available functions.
# Eg: "ydl.download", "ydl.download_with_info_file"
with yt_dlp.YoutubeDL(ydl_opts) as ydl:
    ydl.add_post_processor(MyCustomPP())
    info = ydl.extract_info('https://www.youtube.com/watch?v=BaW_jenozKc')

    # ℹ️ ydl.sanitize_info makes the info json-serializable
    print(json.dumps(ydl.sanitize_info(info)))
```

**Tip**: If you are porting your code from youtube-dl to yt-dlp, one important point to look out for is that we do not guarantee the return value of `YoutubeDL.extract_info` to be json serializable, or even be a dictionary. It will be dictionary-like, but if you want to ensure it is a serializable dictionary, pass it through `YoutubeDL.sanitize_info` as shown in the example above

# DEPRECATED OPTIONS

These are all the deprecated options and the current alternative to achieve the same effect

#### Almost redundant options
While these options are almost the same as their new counterparts, there are some differences that prevents them being redundant

    -j, --dump-json                  --print "%()j"
    -F, --list-formats               --print formats_table
    --list-thumbnails                --print thumbnails_table --print playlist:thumbnails_table
    --list-subs                      --print automatic_captions_table --print subtitles_table

#### Redundant options
While these options are redundant, they are still expected to be used due to their ease of use

    --get-description                --print description
    --get-duration                   --print duration_string
    --get-filename                   --print filename
    --get-format                     --print format
