## UPDATE
You can use `yt-dlp -U` to update if you are using the [release binaries](#release-files)

If you [installed with pip](https://github.com/yt-dlp/yt-dlp/wiki/Installation#with-pip), simply re-run the same command that was used to install the program

For other third-party package managers, see [the wiki](https://github.com/yt-dlp/yt-dlp/wiki/Installation#third-party-package-managers) or refer to their documentation

<a id="update-channels"></a>

There are currently three release channels for binaries: `stable`, `nightly` and `master`.

* `stable` is the default channel, and many of its changes have been tested by users of the `nightly` and `master` channels.
* The `nightly` channel has releases scheduled to build every day around midnight UTC, for a snapshot of the project's new patches and changes. This is the **recommended channel for regular users** of yt-dlp. The `nightly` releases are available from [yt-dlp/yt-dlp-nightly-builds](https://github.com/yt-dlp/yt-dlp-nightly-builds/releases) or as development releases of the `yt-dlp` PyPI package (which can be installed with pip's `--pre` flag).
* The `master` channel features releases that are built after each push to the master branch, and these will have the very latest fixes and additions, but may also be more prone to regressions. They are available from [yt-dlp/yt-dlp-master-builds](https://github.com/yt-dlp/yt-dlp-master-builds/releases).

When using `--update`/`-U`, a release binary will only update to its current channel.
`--update-to CHANNEL` can be used to switch to a different channel when a newer version is available. `--update-to [CHANNEL@]TAG` can also be used to upgrade or downgrade to specific tags from a channel.

You may also use `--update-to <repository>` (`<owner>/<repository>`) to update to a channel on a completely different repository. Be careful with what repository you are updating to though, there is no verification done for binaries from different repositories.

Example usage:

* `yt-dlp --update-to master` switch to the `master` channel and update to its latest release
* `yt-dlp --update-to stable@2023.07.06` upgrade/downgrade to release to `stable` channel tag `2023.07.06`
* `yt-dlp --update-to 2023.10.07` upgrade/downgrade to tag `2023.10.07` if it exists on the current channel
* `yt-dlp --update-to example/yt-dlp@2023.09.24` upgrade/downgrade to the release from the `example/yt-dlp` repository, tag `2023.09.24`

**Important**: Any user experiencing an issue with the `stable` release should install or update to the `nightly` release before submitting a bug report:
```
# To update to nightly from stable executable/binary:
yt-dlp --update-to nightly

# To install nightly with pip:
python3 -m pip install -U --pre "yt-dlp[default]"
```

## DEPENDENCIES
Python versions 3.9+ (CPython) and 3.10+ (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.
-->

While all the other dependencies are optional, `ffmpeg` and `ffprobe` are highly recommended

### Strongly recommended

* [**ffmpeg** and **ffprobe**](https://www.ffmpeg.org) - Required for [merging separate video and audio files](#format-selection), as well as for various [post-processing](#post-processing-options) tasks. License [depends on the build](https://www.ffmpeg.org/legal.html)

    There are bugs in ffmpeg that cause 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 some of 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

    **Important**: What you need is ffmpeg *binary*, **NOT** [the Python package of the same name](https://pypi.org/project/ffmpeg)

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

The standalone release binaries are built with the Python interpreter and the packages marked with **\*** included.

If you do not have the necessary dependencies for a task you are attempting, yt-dlp will warn you. All the currently available dependencies are visible at the top of the `--verbose` output


## COMPILE

### Standalone PyInstaller Builds
To build the standalone executable, you must have Python and `pyinstaller` (plus any of yt-dlp's [optional dependencies](#dependencies) if needed). The executable will be built for the same CPU architecture as the Python used.

You can run the following commands:

```
python3 devscripts/install_deps.py --include pyinstaller
python3 devscripts/make_lazy_extractors.py
python3 -m bundle.pyinstaller
```

On some systems, you may need to use `py` or `python` instead of `python3`.

`python -m bundle.pyinstaller` accepts any arguments that can be passed to `pyinstaller`, such as `--onefile/-F` or `--onedir/-D`, which is further [documented here](https://pyinstaller.org/en/stable/usage.html#what-to-generate).

**Note**: Pyinstaller versions below 4.4 [do not support](https://github.com/pyinstaller/pyinstaller#requirements-and-tested-platforms) Python installed from the Windows store without using a virtual environment.

**Important**: Running `pyinstaller` directly **instead of** using `python -m bundle.pyinstaller` is **not** officially supported. This may or may not work correctly.

### Platform-independent Binary (UNIX)
You will need the build tools `python` (3.9+), `zip`, `make` (GNU), `pandoc`\* and `pytest`\*.

After installing these, simply run `make`.

You can also run `make yt-dlp` instead to compile only the binary without updating any of the additional files. (The build tools marked with **\*** are not needed for this)

### Related scripts

* **`devscripts/install_deps.py`** - Install dependencies for yt-dlp.
* **`devscripts/update-version.py`** - Update the version number based on the current date.
* **`devscripts/set-variant.py`** - Set the build variant of the executable.
* **`devscripts/make_changelog.py`** - Create a markdown changelog using short commit messages and update `CONTRIBUTORS` file.
* **`devscripts/make_lazy_extractors.py`** - Create lazy extractors. Running this before building the binaries (any variant) will improve their startup performance. Set the environment variable `YTDLP_NO_LAZY_EXTRACTORS` to something nonempty to forcefully disable lazy extractor loading.

Note: See their `--help` for more info.

### Forking the project
If you fork the project on GitHub, you can run your fork's [build workflow](.github/workflows/build.yml) to automatically build the selected version(s) as artifacts. Alternatively, you can run the [release workflow](.github/workflows/release.yml) or enable the [nightly workflow](.github/workflows/release-nightly.yml) to create full (pre-)releases.

                                    You can also use regexes, "all", "default"
                                    and "end" (end URL matching); e.g. --ies
                                    "holodex.*,end,youtube". Prefix the name
                                    with a "-" to exclude it, e.g. --ies
                                    default,-generic. Use --list-extractors for
                                    a list of extractor names. (Alias: --ies)
    --default-search PREFIX         Use this prefix for unqualified URLs. E.g.

                                    google videos for the search term "python".
                                    Use the value "auto" to let yt-dlp guess

                                    guessing). "error" just throws an error. The
                                    default value "fixup_error" repairs broken
                                    URLs, but emits an error if this is not
                                    possible instead of searching
    --ignore-config                 Don't load any more configuration files
                                    except those given to --config-locations.
                                    For backward compatibility, if this option
                                    is found inside the system configuration
                                    file, the user configuration is not loaded.
                                    (Alias: --no-config)
    --no-config-locations           Do not load any custom configuration files
                                    (default). When given inside a configuration
                                    file, ignore all previous --config-locations
                                    defined in the current file
    --config-locations PATH         Location of the main configuration file;
                                    either the path to the config or its
                                    containing directory ("-" for stdin). Can be
                                    used multiple times and inside other
                                    configuration files
    --plugin-dirs PATH              Path to an additional directory to search
                                    for plugins. This option can be used
                                    multiple times to add multiple directories.
                                    Note that this currently only works for
                                    extractor plugins; postprocessor plugins can
                                    only be loaded from the default plugin
                                    directories
    --flat-playlist                 Do not extract a playlist's URL result
                                    entries; some entry metadata may be missing
                                    and downloading may be bypassed
    --no-flat-playlist              Fully extract the videos of a playlist
                                    (default)
    --live-from-start               Download livestreams from the start.
                                    Currently only supported for YouTube
                                    (Experimental)
    --no-live-from-start            Download livestreams from the current time
                                    (default)
    --wait-for-video MIN[-MAX]      Wait for scheduled streams to become
                                    available. Pass the minimum number of
                                    seconds (or range) to wait between retries
    --no-wait-for-video             Do not wait for scheduled streams (default)
    --mark-watched                  Mark videos watched (even with --simulate)
    --no-mark-watched               Do not mark videos watched (default)
    --color [STREAM:]POLICY         Whether to emit color codes in output,
                                    optionally prefixed by the STREAM (stdout or
                                    stderr) to apply the setting to. Can be one
                                    of "always", "auto" (default), "never", or
                                    "no_color" (use non color terminal
                                    sequences). Use "auto-tty" or "no_color-tty"
                                    to decide based on terminal support only.
                                    Can be used multiple times
    --compat-options OPTS           Options that can help keep compatibility
                                    with youtube-dl or youtube-dlc
                                    configurations by reverting some of the
                                    changes made in yt-dlp. See "Differences in
                                    default behavior" for details
    --alias ALIASES OPTIONS         Create aliases for an option string. Unless
                                    an alias starts with a dash "-", it is
                                    prefixed with "--". Arguments are parsed
                                    according to the Python string formatting
                                    mini-language. E.g. --alias get-audio,-X
                                    "-S=aext:{0},abr -x --audio-format {0}"
                                    creates options "--get-audio" and "-X" that
                                    takes an argument (ARG0) and expands to
                                    "-S=aext:ARG0,abr -x --audio-format ARG0".
                                    All defined aliases are listed in the --help
                                    output. Alias options can trigger more
                                    aliases; so be careful to avoid defining
                                    recursive options. As a safety measure, each
                                    alias may be triggered a maximum of 100
                                    times. This option can be used multiple times

## Network Options:
    --proxy URL                     Use the specified HTTP/HTTPS/SOCKS proxy. To
                                    enable SOCKS proxy, specify a proper scheme,
                                    e.g. socks5://user:pass@127.0.0.1:1080/.
                                    Pass in an empty string (--proxy "") for
                                    direct connection
    --socket-timeout SECONDS        Time to wait before giving up, in seconds
    --source-address IP             Client-side IP address to bind to
    --impersonate CLIENT[:OS]       Client to impersonate for requests. E.g.
                                    chrome, chrome-110, chrome:windows-10. Pass
                                    --impersonate="" to impersonate any client.
                                    Note that forcing impersonation for all
                                    requests may have a detrimental impact on
                                    download speed and stability
    --list-impersonate-targets      List available clients to impersonate.
    -4, --force-ipv4                Make all connections via IPv4
    -6, --force-ipv6                Make all connections via IPv6
    --enable-file-urls              Enable file:// URLs. This is disabled by
                                    default for security reasons.

## Geo-restriction:
    --geo-verification-proxy URL    Use this proxy to verify the IP address for
                                    some geo-restricted sites. The default proxy
                                    specified by --proxy (or none, if the option
                                    is not present) is used for the actual
                                    downloading
    --xff VALUE                     How to fake X-Forwarded-For HTTP header to
                                    try bypassing geographic restriction. One of
                                    "default" (only when known to be useful),
                                    "never", an IP block in CIDR notation, or a
                                    two-letter ISO 3166-2 country code

## Video Selection:
    -I, --playlist-items ITEM_SPEC  Comma separated playlist_index of the items
                                    to download. You can specify a range using
                                    "[START]:[STOP][:STEP]". For backward
                                    compatibility, START-STOP is also supported.
                                    Use negative indices to count from the right
                                    and negative STEP to download in reverse
                                    order. E.g. "-I 1:3,7,-5::2" used on a
                                    playlist of size 15 will download the items
                                    at index 1,2,3,7,11,13,15
    --min-filesize SIZE             Abort download if filesize is smaller than
                                    SIZE, e.g. 50k or 44.6M
    --max-filesize SIZE             Abort download if filesize is larger than
                                    SIZE, e.g. 50k or 44.6M
    --date DATE                     Download only videos uploaded on this date.
                                    The date can be "YYYYMMDD" or in the format 
                                    [now|today|yesterday][-N[day|week|month|year]].
                                    E.g. "--date today-2weeks" downloads only
                                    videos uploaded on the same day two weeks ago
    --datebefore DATE               Download only videos uploaded on or before
                                    this date. The date formats accepted are the
                                    same as --date
    --dateafter DATE                Download only videos uploaded on or after
                                    this date. The date formats accepted are the
                                    same as --date
    --match-filters FILTER          Generic video filter. Any "OUTPUT TEMPLATE"
                                    field can be compared with a number or a
                                    string using the operators defined in
                                    "Filtering Formats". You can also simply
                                    specify a field to match if the field is
                                    present, use "!field" to check if the field
                                    is not present, and "&" to check multiple
                                    conditions. Use a "\" to escape "&" or
                                    quotes if needed. If used multiple times,
                                    the filter matches if at least one of the
                                    conditions is met. E.g. --match-filters
                                    !is_live --match-filters "like_count>?100 &
                                    description~='(?i)\bcats \& dogs\b'" matches
                                    only videos that are not live OR those that
                                    have a like count more than 100 (or the like
                                    field is not available) and also has a
                                    description that contains the phrase "cats &
                                    dogs" (caseless). Use "--match-filters -" to
                                    interactively ask whether to download each
                                    video
    --no-match-filters              Do not use any --match-filters (default)
    --break-match-filters FILTER    Same as "--match-filters" but stops the
                                    download process when a video is rejected
    --no-break-match-filters        Do not use any --break-match-filters (default)
    --no-playlist                   Download only the video, if the URL refers
                                    to a video and a playlist
    --yes-playlist                  Download the playlist, if the URL refers to
                                    a video and a playlist
    --age-limit YEARS               Download only videos suitable for the given
                                    age
    --download-archive FILE         Download only videos not listed in the
                                    archive file. Record the IDs of all
                                    downloaded videos in it
    --no-download-archive           Do not use archive file (default)
    --max-downloads NUMBER          Abort after downloading NUMBER files
    --break-on-existing             Stop the download process when encountering
                                    a file that is in the archive supplied with
                                    the --download-archive option
    --no-break-on-existing          Do not stop the download process when
                                    encountering a file that is in the archive
                                    (default)
    --break-per-input               Alters --max-downloads, --break-on-existing,
                                    --break-match-filters, and autonumber to
                                    reset per input URL
    --no-break-per-input            --break-on-existing and similar options
                                    terminates the entire download queue
    --skip-playlist-after-errors N  Number of allowed failures until the rest of
                                    the playlist is skipped

## Download Options:
    -N, --concurrent-fragments N    Number of fragments of a dash/hlsnative
                                    video that should be downloaded concurrently
                                    (default is 1)

    --retry-sleep [TYPE:]EXPR       Time to sleep between retries in seconds
                                    (optionally) prefixed by the type of retry

                                    extractor) to apply the sleep to. EXPR can
                                    be a number, linear=START[:END[:STEP=1]] or
                                    exp=START[:END[:BASE=2]]. This option can be
                                    used multiple times to set the sleep for the

                                    to set different downloaders for different
                                    protocols. E.g. --downloader aria2c
                                    --downloader "dash,m3u8:native" will use
                                    aria2c for http/ftp downloads, and the

                                    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:

                                    from other fields; see "MODIFYING METADATA"
                                    for details. Supported values of "WHEN" are
                                    the same as that of --use-postprocessor
                                    (default: pre_process)
    --replace-in-metadata [WHEN:]FIELDS REGEX REPLACE
                                    Replace text in a metadata field using the
                                    given regex. This option can be used
                                    multiple times. Supported values of "WHEN"
                                    are the same as that of --use-postprocessor

                                    (default; only when the videos form a single
                                    show). All the video files must have the
                                    same codecs and number of streams to be
                                    concatenable. The "pl_video:" prefix can be
                                    used with "--paths" and "--output" to set
                                    the output filename for the concatenated
                                    files. See "OUTPUT TEMPLATE" for details

    --exec [WHEN:]CMD               Execute a command, optionally prefixed with
                                    when to execute it, separated by a ":".
                                    Supported values of "WHEN" are the same as
                                    that of --use-postprocessor (default:
                                    after_move). The same syntax as the output
                                    template can be used to pass any field as
                                    arguments to the command. If no fields are
                                    passed, %(filepath,_filename|)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: ass, lrc, srt, vtt).
                                    Use "--convert-subs none" to disable
                                    conversion (default) (Alias: --convert-
                                    subtitles)
    --convert-thumbnails FORMAT     Convert the thumbnails to another format
                                    (currently supported: jpg, png, webp). You
                                    can specify multiple rules using similar
                                    syntax as "--remux-video". Use "--convert-
                                    thumbnails none" to disable conversion
                                    (default)
    --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. The syntax is the
                                    same as --download-sections. This option can
                                    be used multiple times
    --no-remove-chapters            Do not remove any chapters from the file

                                    downloading/splitting/removing sections.
                                    This is slow due to needing a re-encode, 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),
                                    "video" (after --format; before
                                    --print/--output), "before_dl" (before each
                                    video download), "post_process" (after each
                                    video download; default), "after_move"
                                    (after moving the video file to its final
                                    location), "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

                                    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 in a configuration file. The configuration is loaded from the following locations:

1. **Main Configuration**:
    * The file given to `--config-location`
1. **Portable Configuration**: (Recommended for portable installations)
    * If using a binary, `yt-dlp.conf` in the same directory as the binary
    * If running from source-code, `yt-dlp.conf` in the parent directory of `yt_dlp`
1. **Home Configuration**:
    * `yt-dlp.conf` in the home path given to `-P`
    * If `-P` is not given, the current directory is searched
1. **User Configuration**:
    * `${XDG_CONFIG_HOME}/yt-dlp.conf`
    * `${XDG_CONFIG_HOME}/yt-dlp/config` (recommended on Linux/macOS)
    * `${XDG_CONFIG_HOME}/yt-dlp/config.txt`
    * `${APPDATA}/yt-dlp.conf`
    * `${APPDATA}/yt-dlp/config` (recommended on Windows)
    * `${APPDATA}/yt-dlp/config.txt`
    * `~/yt-dlp.conf`
    * `~/yt-dlp.conf.txt`
    * `~/.yt-dlp/config`
    * `~/.yt-dlp/config.txt`

    See also: [Notes about environment variables](#notes-about-environment-variables)
1. **System Configuration**:
    * `/etc/yt-dlp.conf`
    * `/etc/yt-dlp/config`
    * `/etc/yt-dlp/config.txt`

E.g. 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**: Options in a 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`. They must also be quoted when necessary, as if it were a UNIX shell.

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.

### Configuration file encoding

The configuration files are decoded according to the UTF BOM if present, and in the encoding from system locale otherwise.

If you want your file to be decoded differently, add `# coding: ENCODING` to the beginning of the file (e.g. `# coding: shift-jis`). There must be no characters before that, even spaces or BOM.

### Authentication with netrc

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>
```
E.g.
```
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 `~` (see below).

As an alternative to using the `.netrc` file, which has the disadvantage of keeping your passwords in a plain text file, you can configure a custom shell command to provide the credentials for an extractor. This is done by providing the `--netrc-cmd` parameter, it shall output the credentials in the netrc format and return `0` on success, other values will be treated as an error. `{}` in the command will be replaced by the name of the extractor to make it possible to select the credentials for the right extractor.

E.g. To use an encrypted `.netrc` file stored as `.authinfo.gpg`
```
yt-dlp --netrc-cmd 'gpg --decrypt ~/.authinfo.gpg' 'https://www.youtube.com/watch?v=BaW_jenozKc'
```


### Notes about environment variables
* Environment variables are normally specified as `${VARIABLE}`/`$VARIABLE` on UNIX and `%VARIABLE%` on Windows; but is always shown as `${VARIABLE}` in this documentation
* yt-dlp also allows using UNIX-style variables on Windows for path-like options; e.g. `--output`, `--config-location`
* If unset, `${XDG_CONFIG_HOME}` defaults to `~/.config` and `${XDG_CACHE_HOME}` to `~/.cache`
* On Windows, `~` points to `${HOME}` if present; or, `${USERPROFILE}` or `${HOMEDRIVE}${HOMEPATH}` otherwise
* On Windows, `${USERPROFILE}` generally points to `C:\Users\<user name>` and `${APPDATA}` to `${USERPROFILE}\AppData\Roaming`

# 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.

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), e.g. `%(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; e.g. `%(tags.0)s`, `%(subtitles.en.-1.ext)s`. You can do Python slicing with colon `:`; E.g. `%(id.3:7)s`, `%(id.6:2:-1)s`, `%(formats.:.format_id)s`. Curly braces `{}` can be used to build dictionaries with only specific keys; e.g. `%(formats.:.{format_id,height})#j`. An empty field name `%()s` refers to the entire infodict; e.g. `%(.{id,title})s`. Note that all the fields that become available using this method are not listed below. Use `-j` to see such fields

1. **Arithmetic**: Simple arithmetic can be done on numeric fields using `+`, `-` and `*`. E.g. `%(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 `>`. E.g. `%(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 `,`. E.g. `%(release_date>%Y,upload_date>%Y|Unknown)s`

1. **Replacement**: A replacement value can be specified using a `&` separator according to the [`str.format` mini-language](https://docs.python.org/3/library/string.html#format-specification-mini-language). 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. E.g. `%(chapters&has chapters|no chapters)s`, `%(title&TITLE={:>20}|NO TITLE)s`

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

1. **More Conversions**: In addition to the normal format types `diouxXeEfFgGcrs`, yt-dlp additionally supports converting to `B` = **B**ytes, `j` = **j**son (flag `#` for pretty-printing, `+` for Unicode), `h` = HTML escaping, `l` = a comma separated **l**ist (flag `#` for `\n` newline-separated), `q` = a string **q**uoted for the terminal (flag `#` to split a list into different arguments), `D` = add **D**ecimal suffixes (e.g. 10M) (flag `#` to use 1024 as factor), and `S` = **S**anitize as filename (flag `#` for restricted)

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. E.g. `%(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`. E.g. `-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. E.g. `--write-thumbnail -o "thumbnail:"` will write thumbnails only for playlists and not for video.

<a id="outtmpl-postprocess-note"></a>

Each aforementioned sequence when referenced in an output template will be replaced by the actual value corresponding to the sequence name. E.g. 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**: 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); e.g. `%(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.

# 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; e.g. 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 or both (i.e.; `vcodec!=none or acodec!=none`)
 - `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; e.g. `-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); e.g. `-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. E.g. `-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 only `best` 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]"` since filters without a selector are interpreted as `best`).

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

 - `filesize`: The number of bytes, if known in advance
 - `filesize_approx`: An estimate for the number of bytes
 - `width`: Width of the video, if known
 - `height`: Height of the video, if known
 - `aspect_ratio`: Aspect ratio of the video, if known
 - `tbr`: Average bitrate of audio and video in [kbps](## "1000 bits/sec")
 - `abr`: Average audio bitrate in [kbps](## "1000 bits/sec")
 - `vbr`: Average video bitrate in [kbps](## "1000 bits/sec")
 - `asr`: Audio sampling rate in Hertz
 - `fps`: Frame rate
 - `audio_channels`: The number of audio channels
 - `stretched_ratio`: `width:height` of the video's pixels, if not square

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

 - `url`: Video URL
 - `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`)
 - `language`: Language code
 - `dynamic_range`: The dynamic range of the video
 - `format_id`: A short description of the format
 - `format`: A human-readable description of the format
 - `format_note`: Additional info about the format
 - `resolution`: Textual description of width and height

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**: None of the aforementioned meta fields are guaranteed to be present since this solely depends on the metadata obtained by the 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 "bv[height<=?720][tbr>500]"` selects up to 720p videos (or videos where the height is not known) with a bitrate of at least 500 kbps. You can also use the filters with `all` to download all formats that satisfy the filter, e.g. `-f "all[vcodec=none]"` selects all audio-only formats.

Format selectors can also be grouped using parentheses; e.g. `-f "(mp4,webm)[height<480]"` will download the best pre-merged mp4 and webm formats with a height lower than 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 have a video stream
 - `hasaud`: Gives priority to formats that have an 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` > `ac4` > `eac3` > `ac3` > `dts` > other)
 - `codec`: Equivalent to `vcodec,acodec`

**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 `+`. E.g. `+res` prefers format with the smallest resolution. Additionally, you can suffix a preferred value for the fields, separated by a `:`. E.g. `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. E.g. `+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. E.g. `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 behavior can be changed by using `--format-sort-force`. Apart from these, the default order used is: `lang,quality,res,fps,hdr:12,vcodec,channels,acodec,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 for hdr is `hdr:12`; i.e. Dolby Vision is not preferred. This choice was made since DV formats are not yet fully compatible with most devices. This may be changed in the future.

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 > mov > 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 the 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 the 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, a single field name, 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 these options preserve their relative order, allowing replacements to be made in parsed fields and vice versa. Also, any field thus created can be used in the [output template](#output-template) and will also affect the media file's metadata added when using `--embed-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. E.g. `--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 - you can use this to set a different "description" and "synopsis". To modify the metadata of individual streams, use the `meta<n>_` prefix (e.g. `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`, `artists`, `creator`, `creators`, `uploader` or `uploader_id`
`composer`                 | `composer` or `composers`
`genre`                    | `genre` or `genres`
`album`                    | `album`
`album_artist`             | `album_artist` or `album_artists`
`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" --embed-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>.+)" --embed-metadata

# Do not set any "synopsis" in the video metadata
$ yt-dlp --parse-metadata ":(?P<meta_synopsis>)"

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

# 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`. E.g. `--extractor-args "youtube:player-client=tv,mweb;formats=incomplete" --extractor-args "funimation:version=uncut"`

Note: In CLI, `ARG` can use `-` instead of `_`; e.g. `youtube:player-client"` becomes `youtube:player_client"`

The following extractors use this feature:

#### youtube
* `lang`: Prefer translated metadata (`title`, `description` etc) of this language code (case-sensitive). By default, the video primary language metadata is preferred, with a fallback to `en` translated. See [youtube.py](https://github.com/yt-dlp/yt-dlp/blob/c26f9b991a0681fd3ea548d535919cec1fbbd430/yt_dlp/extractor/youtube.py#L381-L390) for list of supported content language codes
* `skip`: One or more of `hls`, `dash` or `translated_subs` to skip extraction of the m3u8 manifests, dash manifests and [auto-translated subtitles](https://github.com/yt-dlp/yt-dlp/issues/4090#issuecomment-1158102032) respectively
* `player_client`: Clients to extract video data from. The main clients are `web`, `ios` and `android`, with variants `_music` and `_creator` (e.g. `ios_creator`); and `mweb`, `android_vr`, `web_safari`, `web_embedded`, `tv` and `tv_embedded` with no variants. By default, `ios,mweb` is used, or `web_creator,mweb` is used when authenticating with cookies. The `_music` variants are added for `music.youtube.com` URLs. Some clients, such as `web` and `android`, require a `po_token` for their formats to be downloadable. Some clients, such as the `_creator` variants, will only work with authentication. Not all clients support authentication via cookies. You can use `all` to use all the clients, and `default` for the default clients. You can prefix a client with `-` to exclude it, e.g. `youtube:player_client=all,-web`
* `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
* `player_params`: YouTube player parameters to use for player requests. Will overwrite any default ones set by yt-dlp.
* `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
* `formats`: Change the types of formats to return. `dashy` (convert HTTP to DASH), `duplicate` (identical content but different URLs or protocol; includes `dashy`), `incomplete` (cannot be downloaded completely - live dash and post-live m3u8)
* `innertube_host`: Innertube API host to use for all API requests; e.g. `studio.youtube.com`, `youtubei.googleapis.com`. Note that cookies exported from one subdomain will not work on others
* `innertube_key`: Innertube API key to use for all API requests. By default, no API key is used
* `raise_incomplete_data`: `Incomplete Data Received` raises an error instead of reporting a warning
* `data_sync_id`: Overrides the account Data Sync ID used in Innertube API requests. This may be needed if you are using an account with `youtube:player_skip=webpage,configs` or `youtubetab:skip=webpage`
* `visitor_data`: Overrides the Visitor Data used in Innertube API requests. This should be used with `player_skip=webpage,configs` and without cookies. Note: this may have adverse effects if used improperly. If a session from a browser is wanted, you should pass cookies instead (which contain the Visitor ID)
* `po_token`:  Proof of Origin (PO) Token(s) to use for requesting video playback. Comma seperated list of PO Tokens in the format `CLIENT+PO_TOKEN`, e.g. `youtube:po_token=web+XXX,android+YYY`

#### 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` and `timestamp` in flat-playlist. This may cause date-based filters to be slightly off

#### generic
* `fragment_query`: Passthrough any query in mpd/m3u8 manifest URLs to their fragments if no value is provided, or else apply the query string given as `fragment_query=VALUE`. Note that if the stream has an HLS AES-128 key, then the query parameters will be passed to the key URI as well, unless the `key_query` extractor-arg is passed, or unless an external key URI is provided via the `hls_key` extractor-arg. Does not apply to ffmpeg
* `variant_query`: Passthrough the master m3u8 URL query to its variant playlist URLs if no value is provided, or else apply the query string given as `variant_query=VALUE`
* `key_query`: Passthrough the master m3u8 URL query to its HLS AES-128 decryption key URI if no value is provided, or else apply the query string given as `key_query=VALUE`. Note that this will have no effect if the key URI is provided via the `hls_key` extractor-arg. Does not apply to ffmpeg
* `hls_key`: An HLS AES-128 key URI *or* key (as hex), and optionally the IV (as hex), in the form of `(URI|KEY)[,IV]`; e.g. `generic:hls_key=ABCDEF1234567980,0xFEDCBA0987654321`. Passing any of these values will force usage of the native HLS downloader and override the corresponding values found in the m3u8 playlist
* `is_live`: Bypass live HLS detection and manually set `live_status` - a value of `false` will set `not_live`, any other value (or no value) will set `is_live`
* `impersonate`: Target(s) to try and impersonate with the initial webpage request; e.g. `generic:impersonate=safari,chrome-110`. Use `generic:impersonate` to impersonate any available target, and use `generic:impersonate=false` to disable impersonation (default)

#### funimation
* `language`: Audio languages to extract, e.g. `funimation:language=english,japanese`
* `version`: The video version to extract - `uncut` or `simulcast`

#### crunchyrollbeta (Crunchyroll)
* `hardsub`: One or more hardsub versions to extract (in order of preference), or `all` (default: `None` = no hardsubs will be extracted), e.g. `crunchyrollbeta:hardsub=en-US,de-DE`

#### 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`

#### niconicochannelplus
* `max_comments`: Maximum number of comments to extract - default is `120`

#### tiktok
* `api_hostname`: Hostname to use for mobile API calls, e.g. `api22-normal-c-alisg.tiktokv.com`
* `app_name`: Default app name to use with mobile API calls, e.g. `trill`
* `app_version`: Default app version to use with mobile API calls - should be set along with `manifest_app_version`, e.g. `34.1.2`
* `manifest_app_version`: Default numeric app version to use with mobile API calls, e.g. `2023401020`
* `aid`: Default app ID to use with mobile API calls, e.g. `1180`
* `app_info`: Enable mobile API extraction with one or more app info strings in the format of `<iid>/[app_name]/[app_version]/[manifest_app_version]/[aid]`, where `iid` is the unique app install ID. `iid` is the only required value; all other values and their `/` separators can be omitted, e.g. `tiktok:app_info=1234567890123456789` or `tiktok:app_info=123,456/trill///1180,789//34.0.1/340001`
* `device_id`: Enable mobile API extraction with a genuine device ID to be used with mobile API calls. Default is a random 19-digit string

#### rokfinchannel
* `tab`: Which tab to download - one of `new`, `top`, `videos`, `podcasts`, `streams`, `stacks`

#### twitter
* `api`: Select one of `graphql` (default), `legacy` or `syndication` as the API for tweet extraction. Has no effect if logged in

#### stacommu, wrestleuniverse
* `device_id`: UUID value assigned by the website and used to enforce device limits for paid livestream content. Can be found in browser local storage

#### twitch

#### soundcloud
* `formats`: Formats to request from the API. Requested values should be in the format of `{protocol}_{extension}` (omitting the bitrate), e.g. `hls_opus,http_aac`. The `*` character functions as a wildcard, e.g. `*_mp3`, and can be passed by itself to request all formats. Known protocols include `http`, `hls` and `hls-aes`; known extensions include `aac`, `opus` and `mp3`. Original `download` formats are always extracted. Default is `http_aac,hls_aac,http_opus,hls_opus,http_mp3,hls_mp3`

#### orfon (orf:on)

#### sonylivseries
* `sort_order`: Episode sort order for series extraction - one of `asc` (ascending, oldest first) or `desc` (descending, newest first). Default is `asc`

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

# 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!**

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.
- Extractor plugins take priority over built-in extractors.
- Postprocessor plugins can be invoked using `--use-postprocessor NAME`.


Plugins are loaded from the namespace packages `yt_dlp_plugins.extractor` and `yt_dlp_plugins.postprocessor`.

In other words, the file structure on the disk looks something like:

        yt_dlp_plugins/
            extractor/
                myplugin.py
            postprocessor/
                myplugin.py

yt-dlp looks for these `yt_dlp_plugins` namespace folders in many locations (see below) and loads in plugins from **all** of them.
Set the environment variable `YTDLP_NO_PLUGINS` to something nonempty to disable loading plugins entirely.

See the [wiki for some known plugins](https://github.com/yt-dlp/yt-dlp/wiki/Plugins)

## Installing Plugins

Plugins can be installed using various methods and locations.

1. **Configuration directories**:
   Plugin packages (containing a `yt_dlp_plugins` namespace folder) can be dropped into the following standard [configuration locations](#configuration):
    * **User Plugins**
      * `${XDG_CONFIG_HOME}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Linux/macOS)
      * `${XDG_CONFIG_HOME}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
      * `${APPDATA}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Windows)
      * `${APPDATA}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
      * `~/.yt-dlp/plugins/<package name>/yt_dlp_plugins/`
      * `~/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
    * **System Plugins**
      * `/etc/yt-dlp/plugins/<package name>/yt_dlp_plugins/`
      * `/etc/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
2. **Executable location**: Plugin packages can similarly be installed in a `yt-dlp-plugins` directory under the executable location (recommended for portable installations):
    * Binary: where `<root-dir>/yt-dlp.exe`, `<root-dir>/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
    * Source: where `<root-dir>/yt_dlp/__main__.py`, `<root-dir>/yt-dlp-plugins/<package name>/yt_dlp_plugins/`

3. **pip and other locations in `PYTHONPATH`**
    * Plugin packages can be installed and managed using `pip`. See [yt-dlp-sample-plugins](https://github.com/yt-dlp/yt-dlp-sample-plugins) for an example.
      * Note: plugin files between plugin packages installed with pip must have unique filenames.
    * Any path in `PYTHONPATH` is searched in for the `yt_dlp_plugins` namespace folder.
      * Note: This does not apply for Pyinstaller builds.


`.zip`, `.egg` and `.whl` archives containing a `yt_dlp_plugins` namespace folder in their root are also supported as plugin packages.

* e.g. `${XDG_CONFIG_HOME}/yt-dlp/plugins/mypluginpkg.zip` where `mypluginpkg.zip` contains `yt_dlp_plugins/<type>/myplugin.py`

Run yt-dlp with `--verbose` to check if the plugin has been loaded.

## Developing Plugins

See the [yt-dlp-sample-plugins](https://github.com/yt-dlp/yt-dlp-sample-plugins) repo for a template plugin package and the [Plugin Development](https://github.com/yt-dlp/yt-dlp/wiki/Plugin-Development) section of the wiki for a plugin development guide.

All public classes with a name ending in `IE`/`PP` are imported from each file for extractors and postprocessors respectively. This respects underscore prefix (e.g. `_MyBasePluginIE` is private) and `__all__`. Modules can similarly be excluded by prefixing the module name with an underscore (e.g. `_myplugin.py`).

To replace an existing extractor with a subclass of one, set the `plugin_name` class keyword argument (e.g. `class MyPluginIE(ABuiltInIE, plugin_name='myplugin')` will replace `ABuiltInIE` with `MyPluginIE`). Since the extractor replaces the parent, you should exclude the subclass extractor from being imported separately by making it private using one of the methods described above.

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

See the [Developer Instructions](https://github.com/yt-dlp/yt-dlp/blob/master/CONTRIBUTING.md#developer-instructions) on how to write and test an extractor.

# 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

URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
with YoutubeDL() as ydl:
    ydl.download(URLS)
```

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#L183) or `help(yt_dlp.YoutubeDL)` in a Python shell. If you are already familiar with the CLI, you can use [`devscripts/cli_to_api.py`](https://github.com/yt-dlp/yt-dlp/blob/master/devscripts/cli_to_api.py) to translate any CLI switches to `YoutubeDL` params.

**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 below](#extracting-information)

## Embedding examples

#### Extracting information

```python
import json
import yt_dlp

URL = 'https://www.youtube.com/watch?v=BaW_jenozKc'

# ℹ️ See help(yt_dlp.YoutubeDL) for a list of available options and public functions
ydl_opts = {}
with yt_dlp.YoutubeDL(ydl_opts) as ydl:
    info = ydl.extract_info(URL, download=False)

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

```python
import yt_dlp

INFO_FILE = 'path/to/video.info.json'

with yt_dlp.YoutubeDL() as ydl:
    error_code = ydl.download_with_info_file(INFO_FILE)

print('Some videos failed to download' if error_code
      else 'All videos successfully downloaded')
```

#### Extract audio

```python
import yt_dlp

URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']

ydl_opts = {
    'format': 'm4a/bestaudio/best',
    # ℹ️ See help(yt_dlp.postprocessor) for a list of available Postprocessors and their arguments
    'postprocessors': [{  # Extract audio using ffmpeg
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'm4a',
    }]
}

with yt_dlp.YoutubeDL(ydl_opts) as ydl:
    error_code = ydl.download(URLS)
```

#### Filter videos

```python
import yt_dlp

URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']

def longer_than_a_minute(info, *, incomplete):
    """Download only videos longer than a minute (or with unknown duration)"""
    duration = info.get('duration')
    if duration and duration < 60:
        return 'The video is too short'

ydl_opts = {
    'match_filter': longer_than_a_minute,
}

with yt_dlp.YoutubeDL(ydl_opts) as ydl:
    error_code = ydl.download(URLS)
```

#### Adding logger and progress hook

```python
import yt_dlp

URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']

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 "progress_hooks" in help(yt_dlp.YoutubeDL)
def my_hook(d):
    if d['status'] == 'finished':
        print('Done downloading, now post-processing ...')


ydl_opts = {
    'logger': MyLogger(),
    'progress_hooks': [my_hook],
}

with yt_dlp.YoutubeDL(ydl_opts) as ydl:
    ydl.download(URLS)
```

#### Add a custom PostProcessor

```python
import yt_dlp

URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']

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


with yt_dlp.YoutubeDL() as ydl:
    # ℹ️ "when" can take any value in yt_dlp.utils.POSTPROCESS_WHEN
    ydl.add_post_processor(MyCustomPP(), when='pre_process')
    ydl.download(URLS)
```


#### Use a custom format selector

```python
import yt_dlp

URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']

def format_selector(ctx):
    """ Select the best video and the best audio that won't result in an mkv.
    NOTE: 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))

    # These are the minimum required fields for a merged format
    yield {
        '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"]}'
    }


ydl_opts = {
    'format': format_selector,
}

with yt_dlp.YoutubeDL(ydl_opts) as ydl:
    ydl.download(URLS)
```


# CHANGES FROM YOUTUBE-DL

### New features

* Forked from [**yt-dlc@f9401f2**](https://github.com/blackjack4494/yt-dlc/commit/f9401f2a91987068139c5f757b12fc711d4c0cee) and merged with [**youtube-dl@a08f2b7**](https://github.com/ytdl-org/youtube-dl/commit/a08f2b7e4567cdc50c0614ee0a4ffdff49b8b6e6) ([exceptions](https://github.com/yt-dlp/yt-dlp/issues/21))

* **[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 NicoNico livestreams are not available. See [#31](https://github.com/yt-dlp/yt-dlp/pull/31) for details.

* **YouTube improvements**:
    * Supports Clips, Stories (`ytstories:<channel UCID>`), Search (including filters)**\***, YouTube Music Search, Channel-specific search, Search prefixes (`ytsearch:`, `ytsearchdate:`)**\***, Mixes, and Feeds (`:ytfav`, `:ytwatchlater`, `:ytsubs`, `:ythistory`, `:ytrec`, `:ytnotif`)
    * Fix for [n-sig based throttling](https://github.com/ytdl-org/youtube-dl/issues/29326) **\***
    * Download livestreams from the start using `--live-from-start` (*experimental*)
    * Channel URLs download all uploads of the channel, including shorts and live
    * Support for [logging in with OAuth](https://github.com/yt-dlp/yt-dlp/wiki/Extractors#logging-in-with-oauth)

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

* **Download time range**: Videos can be downloaded partially based on either timestamps or chapters using `--download-sections`

* **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 etc.

* **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 `--alias`, `--print`, `--concat-playlist`, `--wait-for-video`, `--retry-sleep`, `--sleep-requests`, `--convert-thumbnails`, `--force-download-archive`, `--force-overwrites`, `--break-match-filters` etc

* **Improvements**: Regex and other operators in `--format`/`--match-filters`, 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`, and downgraded using `--update-to` if required

* **Automated builds**: [Nightly/master builds](#update-channels) can be used with `--update-to nightly` and `--update-to master`

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

Features marked with a **\*** have been back-ported to youtube-dl

### Differences in default behavior

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

* yt-dlp supports only [Python 3.9+](## "Windows 8"), and will remove support for more versions as they [become EOL](https://devguide.python.org/versions/#python-release-cycle); while [youtube-dl still supports Python 2.6+ and 3.2+](https://github.com/ytdl-org/youtube-dl/issues/30568#issue-1118238743)
* 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. Older versions of yt-dlp preferred VP9 due to its broader compatibility; you can use `--compat-options prefer-vp9-sort` to revert to that format sorting preference. These two compat options cannot be used together
* 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
* Live chats (if available) are considered as subtitles. Use `--sub-langs all,-live_chat` to download all subtitles except live chat. You can also use `--compat-options no-live-chat` to prevent any live chat/danmaku from downloading
* YouTube channel URLs download all uploads of the channel. To download only the videos in a specific tab, pass the tab's URL. 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
* The upload dates extracted from YouTube are in UTC [when available](https://github.com/yt-dlp/yt-dlp/blob/89e4d86171c7b7c997c77d4714542e0383bf0db0/yt_dlp/extractor/youtube.py#L3898-L3900). Use `--compat-options no-youtube-prefer-utc-upload-date` to prefer the non-UTC upload date.
* 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 internal metadata 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`
* yt-dlp's sanitization of invalid characters in filenames is different/smarter than in youtube-dl. You can use `--compat-options filename-sanitization` to revert to youtube-dl's behavior
* ~~yt-dlp tries to parse the external downloader outputs into the standard progress output if possible (Currently implemented: [aria2c](https://github.com/yt-dlp/yt-dlp/issues/5931)). You can use `--compat-options no-external-downloader-progress` to get the downloader output as-is~~
* yt-dlp versions between 2021.09.01 and 2023.01.02 applies `--match-filters` to nested playlists. This was an unintentional side-effect of [8f18ac](https://github.com/yt-dlp/yt-dlp/commit/8f18aca8717bb0dd49054555af8d386e5eda3a88) and is fixed in [d7b460](https://github.com/yt-dlp/yt-dlp/commit/d7b460d0e5fc710950582baed2e3fc616ed98a80). Use `--compat-options playlist-match-filter` to revert this
* yt-dlp versions between 2021.11.10 and 2023.06.21 estimated `filesize_approx` values for fragmented/manifest formats. This was added for convenience in [f2fe69](https://github.com/yt-dlp/yt-dlp/commit/f2fe69c7b0d208bdb1f6292b4ae92bc1e1a7444a), but was reverted in [0dff8e](https://github.com/yt-dlp/yt-dlp/commit/0dff8e4d1e6e9fb938f4256ea9af7d81f42fd54f) due to the potentially extreme inaccuracy of the estimated values. Use `--compat-options manifest-filesize-approx` to keep extracting the estimated values
* yt-dlp uses modern http client backends such as `requests`. Use `--compat-options prefer-legacy-http-handler` to prefer the legacy http handler (`urllib`) to be used for standard http requests.
* The sub-modules `swfinterp`, `casefold` are removed.
* Passing `--simulate` (or calling `extract_info` with `download=False`) no longer alters the default format selection. See [#9843](https://github.com/yt-dlp/yt-dlp/issues/9843) for details.

For ease of use, a few more compat options are available:

* `--compat-options all`: Use all compat options (**Do NOT use this!**)
* `--compat-options youtube-dl`: Same as `--compat-options all,-multistreams,-playlist-match-filter,-manifest-filesize-approx,-allow-unsafe-ext,-prefer-vp9-sort`
* `--compat-options youtube-dlc`: Same as `--compat-options all,-no-live-chat,-no-youtube-channel-redirect,-playlist-match-filter,-manifest-filesize-approx,-allow-unsafe-ext,-prefer-vp9-sort`
* `--compat-options 2021`: Same as `--compat-options 2022,no-certifi,filename-sanitization,no-youtube-prefer-utc-upload-date`
* `--compat-options 2022`: Same as `--compat-options 2023,playlist-match-filter,no-external-downloader-progress,prefer-legacy-http-handler,manifest-filesize-approx`
* `--compat-options 2023`: Same as `--compat-options prefer-vp9-sort`. Use this to enable all future compat options

The following compat options restore vulnerable behavior from before security patches:

* `--compat-options allow-unsafe-ext`: Allow files with any extension (including unsafe ones) to be downloaded ([GHSA-79w7-vh3h-8g4j](<https://github.com/yt-dlp/yt-dlp/security/advisories/GHSA-79w7-vh3h-8g4j>))

    > :warning: Only use if a valid file download is rejected because its extension is detected as uncommon
    >
    > **This option can enable remote code execution! Consider [opening an issue](<https://github.com/yt-dlp/yt-dlp/issues/new/choose>) instead!**

### 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
    --get-id                         --print id
    --get-thumbnail                  --print thumbnail
    -e, --get-title                  --print title
    -g, --get-url                    --print urls
    --match-title REGEX              --match-filters "title ~= (?i)REGEX"
    --reject-title REGEX             --match-filters "title !~= (?i)REGEX"
    --min-views COUNT                --match-filters "view_count >=? COUNT"
    --max-views COUNT                --match-filters "view_count <=? COUNT"
    --break-on-reject                Use --break-match-filters
    --user-agent UA                  --add-headers "User-Agent:UA"
    --referer URL                    --add-headers "Referer:URL"
    --playlist-start NUMBER          -I NUMBER:
    --playlist-end NUMBER            -I :NUMBER
    --playlist-reverse               -I ::-1
    --no-playlist-reverse            Default
    --no-colors                      --color no_color

#### Not recommended
While these options still work, their use is not recommended since there are other alternatives to achieve the same

    --force-generic-extractor        --ies generic,default
    --exec-before-download CMD       --exec "before_dl:CMD"
    --no-exec-before-download        --no-exec
