NEW FEATURES
-
Forked from yt-dlc@f9401f2 and merged with youtube-dl@66ab08 (exceptions)
-
SponsorBlock Integration: You can mark/remove sponsor sections in YouTube videos by utilizing the SponsorBlock API
-
Format Sorting: 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) -
Merged with animelover1984/youtube-dl: You get most of the features and improvements from 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 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 *
- Supports some (but not all) age-gated content without cookies
- Download livestreams from the start using
--live-from-start(experimental) 255kbpsaudio is extracted (if available) from YouTube Music when premium cookies are given- Channel URLs download all uploads of the channel, including shorts and live
- Supports Clips, Stories (
-
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
aria2cas 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 or the list of supported sites
-
New MSOs: Philo, Spectrum, SlingTV, Cablevision, RCN etc.
-
Subtitle extraction from manifests: Subtitles can be extracted from streaming media manifests. See commit/be6202f for details
-
Multiple paths and output templates: You can give different output templates 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 for details
-
Output template improvements: Output templates can now have date-time formatting, numeric offsets, object traversal etc. See output template for details. Even more advanced operations can also be done with the help of
--parse-metadataand--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-filteretc -
Improvements: Regex and other operators in
--format/--match-filter, multiple--postprocessor-argsand--downloader-args, faster archive checking, more format selection options, merge multi-video/audio, multiple--config-locations,--execat different stages, etc -
Plugins: Extractors and PostProcessors can be loaded from an external file. See plugins for details
-
Self updater: The releases can be updated using
yt-dlp -U, and downgraded using--update-toif required -
Nightly builds: Automated nightly builds can be used with
--update-to nightly
See changelog or 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 3.7+, and may remove support for more versions as they become EOL; while youtube-dl still supports Python 2.6+ and 3.2+
- The options
--auto-number(-A),--title(-t) and--literal(-l), no longer work. See removed options for details avconvis not supported as an alternative toffmpeg- yt-dlp stores config files in slightly different locations to youtube-dl. See CONFIGURATION for a list of correct locations
- The default 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 is different from youtube-dl and prefers higher resolution and better codecs rather than higher bitrates. You can use the
--format-sortoption to change this to any order you prefer, or use--compat-options format-sortto use youtube-dl's sorting order - The default format selector is
bv*+ba/b. This means that if a combined video + audio format that is better than the best video-only format is found, the former will be preferred. Use-f bv+ba/bor--compat-options format-specto 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-multistreamsand--video-multistreams. You can also use--compat-options multistreamsto enable both --no-abort-on-erroris enabled by default. Use--abort-on-erroror--compat-options abort-on-errorto 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-metafilesor--compat-options no-playlist-metafilesto not write these files --add-metadataattaches theinfojsontomkvfiles in addition to writing the metadata when used with--write-info-json. Use--no-embed-info-jsonor--compat-options no-attach-info-jsonto revert this- Some metadata are embedded into different fields when using
--add-metadataas compared to youtube-dl. Most notably,commentfield contains thewebpage_urlandsynopsiscontains thedescription. You can use--parse-metadatato modify this to your liking or use--compat-options embed-metadatato revert this playlist_indexbehaves differently when used with options like--playlist-reverseand--playlist-items. See #302 for details. You can use--compat-options playlist-indexif you want to keep the earlier behavior- The output of
-Fis listed in a new format. Use--compat-options list-formatsto revert this - Live chats (if available) are considered as subtitles. Use
--sub-langs all,-live_chatto download all subtitles except live chat. You can also use--compat-options no-live-chatto 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,
/liveURLs raise an error if there are no live videos instead of silently downloading the entire channel. You may use--compat-options no-youtube-channel-redirectto revert all these redirections - Unavailable videos are also listed for YouTube playlists. Use
--compat-options no-youtube-unavailable-videosto remove this - The upload dates extracted from YouTube are in UTC when available. Use
--compat-options no-youtube-prefer-utc-upload-dateto prefer the non-UTC upload date. - If
ffmpegis used as the downloader, the downloading and merging of formats happen in a single step when possible. Use--compat-options no-direct-mergeto revert this - Thumbnail embedding in
mp4is done with mutagen if possible. Use--compat-options embed-thumbnail-atomicparsleyto force the use of AtomicParsley instead - Some internal metadata such as filenames are removed by default from the infojson. Use
--no-clean-infojsonor--compat-options no-clean-infojsonto revert this - When
--embed-subsand--write-subsare used together, the subtitles are written to disk and also embedded in the media file. You can use just--embed-substo embed the subs and automatically delete the separate file. See #630 (comment) for more info.--compat-options no-keep-subscan be used to revert this certifiwill 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-sanitizationto 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). You can use--compat-options no-external-downloader-progressto get the downloader output as-is - yt-dlp versions between 2021.09.01 and 2023.01.02 applies
--match-filterto nested playlists. This was an unintentional side-effect of 8f18ac and is fixed in d7b460. Use--compat-options playlist-match-filterto revert this
For ease of use, a few more compat options are available:
--compat-options all: Use all compat options (Do NOT use)--compat-options youtube-dl: Same as--compat-options all,-multistreams,-playlist-match-filter--compat-options youtube-dlc: Same as--compat-options all,-no-live-chat,-no-youtube-channel-redirect,-playlist-match-filter--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 playlist-match-filter,no-external-downloader-progress. Use this to enable all future compat options
INSTALLATION
You can install yt-dlp using the binaries, pip or one using a third-party package manager. See the wiki for detailed instructions
UPDATE
You can use yt-dlp -U to update if you are using the release binaries
If you installed with pip, simply re-run the same command that was used to install the program
For other third-party package managers, see the wiki or refer their documentation
There are currently two release channels for binaries, stable and nightly.
stable is the default channel, and many of its changes have been tested by users of the nightly channel.
The nightly channel has releases built after each push to the master branch, and will have the most recent fixes and additions, but also have more risk of regressions. They are available in their own repo.
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 nightlychange tonightlychannel and update to its latest releaseyt-dlp --update-to stable@2023.02.17upgrade/downgrade to release tostablechannel tag2023.02.17yt-dlp --update-to 2023.01.06upgrade/downgrade to tag2023.01.06if it exists on the current channelyt-dlp --update-to example/yt-dlp@2023.03.01upgrade/downgrade to the release from theexample/yt-dlprepository, tag2023.03.01

DEPENDENCIES
Python versions 3.7+ (CPython and PyPy) are supported. Other versions and implementations may or may not work correctly.
While all the other dependencies are optional, ffmpeg and ffprobe are highly recommended
Strongly recommended
-
ffmpeg and ffprobe - Required for merging separate video and audio files as well as for various post-processing tasks. License depends on the build
There are bugs in ffmpeg that causes various issues when used alongside yt-dlp. Since ffmpeg is such an important dependency, we provide custom builds with patches for some of these issues at yt-dlp/FFmpeg-Builds. See the readme 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

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 if needed). Once you have all the necessary dependencies installed, simply run pyinst.py. The executable will be built for the same architecture (x86/ARM, 32/64 bit) as the Python used.
python3 -m pip install -U pyinstaller -r requirements.txt
python3 devscripts/make_lazy_extractors.py
python3 pyinst.py
On some systems, you may need to use py or python instead of python3.
pyinst.py accepts any arguments that can be passed to pyinstaller, such as --onefile/-F or --onedir/-D, which is further documented here.
Note: Pyinstaller versions below 4.4 do not support Python installed from the Windows store without using a virtual environment.
Important: Running pyinstaller directly without using pyinst.py is not officially supported. This may or may not work correctly.
Platform-independent Binary (UNIX)
You will need the build tools python (3.7+), 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)
Standalone Py2Exe Builds (Windows)
While we provide the option to build with py2exe, it is recommended to build using PyInstaller instead since the py2exe builds cannot contain pycryptodomex/certifi and needs VC++14 on the target computer to run.
If you wish to build it anyway, install Python and py2exe, and then simply run setup.py py2exe
py -m pip install -U py2exe -r requirements.txt
py devscripts/make_lazy_extractors.py
py setup.py py2exe
Related scripts

Running this before building the binaries (any variant) will improve their startup performance. Set the environment variableYTDLP_NO_LAZY_EXTRACTORS=1if you wish 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 to automatically build the selected version(s) as artifacts. Alternatively, you can run the release workflow or enable the nightly workflow to create full (pre-)releases.
USAGE AND OPTIONS
yt-dlp [OPTIONS] [--] URL [URL...]
Ctrl+F is your friend :D
General Options:
-h, --help Print this help text and exit
--version Print program version and exit
-U, --update Update this program to the latest version
--no-update Do not check for updates (default)
--update-to [CHANNEL]@[TAG] Upgrade/downgrade to a specific version.
CHANNEL can be a repository as well. CHANNEL
and TAG default to "stable" and "latest"
respectively if omitted; See "UPDATE" for
details. Supported channels: stable, nightly
-i, --ignore-errors Ignore download and postprocessing errors.
The download will be considered successful
even if the postprocessing fails
--no-abort-on-error Continue with next video on download errors;
e.g. to skip unavailable videos in a
playlist (default)
--abort-on-error Abort downloading of further videos if an
error occurs (Alias: --no-ignore-errors)
--dump-user-agent Display the current user-agent and exit
--list-extractors List all supported extractors and exit
--extractor-descriptions Output descriptions of all supported
extractors and exit
--use-extractors NAMES Extractor names to use separated by commas.
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.
"gvsearch2:python" downloads two videos from
google videos for the search term "python".
Use the value "auto" to let yt-dlp guess
("auto_warning" to emit a warning when
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 by --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
--flat-playlist Do not extract the videos of a playlist,
only list them
--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). 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
-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 is the
same as --date
--dateafter DATE Download only videos uploaded on or after
this date. The date formats accepted is 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 atleast one of the
conditions are met. E.g. --match-filter
!is_live --match-filter "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-filter -" to
interactively ask whether to download each
video
--no-match-filters Do not use any --match-filter (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
--break-per-input Alters --max-downloads, --break-on-existing,
--break-match-filter, 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)
-r, --limit-rate RATE Maximum download rate in bytes per second,
e.g. 50K or 4.2M
--throttled-rate RATE Minimum download rate in bytes per second
below which throttling is assumed and the
video data is re-extracted, e.g. 100K
-R, --retries RETRIES Number of retries (default is 10), or
"infinite"
--file-access-retries RETRIES Number of times to retry on file access
error (default is 3), or "infinite"
--fragment-retries RETRIES Number of retries for a fragment (default is
10), or "infinite" (DASH, hlsnative and ISM)
--retry-sleep [TYPE:]EXPR Time to sleep between retries in seconds
(optionally) prefixed by the type of retry
(http (default), fragment, file_access,
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
different retry types, e.g. --retry-sleep
linear=1::2 --retry-sleep fragment:exp=1:20
--skip-unavailable-fragments Skip unavailable fragments for DASH,
hlsnative and ISM downloads (default)
(Alias: --no-abort-on-unavailable-fragments)
--abort-on-unavailable-fragments
Abort download if a fragment is unavailable
(Alias: --no-skip-unavailable-fragments)
--keep-fragments Keep downloaded fragments on disk after
downloading is finished
--no-keep-fragments Delete downloaded fragments after
downloading is finished (default)
--buffer-size SIZE Size of download buffer, e.g. 1024 or 16K
(default is 1024)
--resize-buffer The buffer size is automatically resized
from an initial value of --buffer-size
(default)
--no-resize-buffer Do not automatically adjust the buffer size
--http-chunk-size SIZE Size of a chunk for chunk-based HTTP
downloading, e.g. 10485760 or 10M (default
is disabled). May be useful for bypassing
bandwidth throttling imposed by a webserver
(experimental)
--playlist-random Download playlist videos in random order
--lazy-playlist Process entries in the playlist as they are
received. This disables n_entries,

CONFIGURATION
You can configure yt-dlp by placing any supported command line option to a configuration file. The configuration is loaded from the following locations:
-
Main Configuration:
- The file given by
--config-location
- The file given by
-
Portable Configuration: (Recommended for portable installations)
- If using a binary,
yt-dlp.confin the same directory as the binary - If running from source-code,
yt-dlp.confin the parent directory ofyt_dlp
- If using a binary,
-
Home Configuration:
yt-dlp.confin the home path given by-P- If
-Pis not given, the current directory is searched
-
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
-
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 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 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.
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
${VARIABLE}/$VARIABLEon UNIX and%VARIABLE%on Windows; but is always shown as${VARIABLE}in this documentation - yt-dlp also allow using UNIX-style variables on Windows for path-like options; e.g.
--output,--config-location - If unset,
${XDG_CONFIG_HOME}defaults to~/.configand${XDG_CACHE_HOME}to~/.cache - On Windows,
~points to${HOME}if present; or,${USERPROFILE}or${HOMEDRIVE}${HOMEPATH}otherwise - On Windows,
${USERPROFILE}generally points toC:\Users\<user name>and${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.
tl;dr: navigate me to examples.
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, 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:
-
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:-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%()srefers 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-jto see such fields -
Addition: Addition and subtraction of numeric fields can be done using
+and-respectively. E.g.%(playlist_index+10)03d,%(n_entries+1-playlist_index)d -
Date/time Formatting: Date/time fields can be formatted according to strftime formatting 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 -
Alternatives: Alternate fields can be specified separated with a
,. E.g.%(release_date>%Y,upload_date>%Y|Unknown)s -
Replacement: A replacement value can be specified using a
&separator according to thestr.formatmini-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 -
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 -
More Conversions: In addition to the normal format types
diouxXeEfFgGcrs, yt-dlp additionally supports converting toB= Bytes,j= json (flag#for pretty-printing,+for Unicode),h= HTML escaping,l= a comma separated list (flag#for\nnewline-separated),q= a string quoted for the terminal (flag#to split a list into different arguments),D= add Decimal suffixes (e.g. 10M) (flag#to use 1024 as factor), andS= Sanitize as filename (flag#for restricted) -
Unicode normalization: The format type
Ucan be used for NFC Unicode normalization. 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)+.100Uis 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.
Note: Due to post-processing (i.e. merging etc.), the actual output filename might differ. Use --print after_move:filepath to get the name after all post-processing is complete.

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; 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.
tl;dr: navigate me to examples.
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 separatelymergeall: Select and merge all formats (Must be used with--audio-multistreams,--video-multistreamsor both)b*,best*: Select the best quality format that contains either a video or an audio or both (ie;vcodec!=none or acodec!=none)b,best: Select the best quality format that contains both video and audio. Equivalent tobest*[vcodec!=none][acodec!=none]bv,bestvideo: Select the best quality video-only format. Equivalent tobest*[acodec=none]bv*,bestvideo*: Select the best quality format that contains video. It may also contain audio. Equivalent tobest*[vcodec!=none]ba,bestaudio: Select the best quality audio-only format. Equivalent tobest*[vcodec=none]ba*,bestaudio*: Select the best quality format that contains audio. It may also contain video. Equivalent tobest*[acodec!=none](Do not use!)w*,worst*: Select the worst quality format that contains either a video or an audiow,worst: Select the worst quality format that contains both video and audio. Equivalent toworst*[vcodec!=none][acodec!=none]wv,worstvideo: Select the worst quality video-only format. Equivalent toworst*[acodec=none]wv*,worstvideo*: Select the worst quality format that contains video. It may also contain audio. Equivalent toworst*[vcodec!=none]wa,worstaudio: Select the worst quality audio-only format. Equivalent toworst*[vcodec=none]wa*,worstaudio*: Select the worst quality format that contains audio. It may also contain video. Equivalent toworst*[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 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 advancefilesize_approx: An estimate for the number of byteswidth: Width of the video, if knownheight: Height of the video, if knownaspect_ratio: Aspect ratio of the video, if knowntbr: Average bitrate of audio and video in KBit/sabr: Average audio bitrate in KBit/svbr: Average video bitrate in KBit/sasr: Audio sampling rate in Hertzfps: Frame rateaudio_channels: The number of audio channelsstretched_ratio:width:heightof 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 URLext: File extensionacodec: Name of the audio codec in usevcodec: Name of the video codec in usecontainer: Name of the container formatprotocol: The protocol that will be used for the actual download, lower-case (http,https,rtsp,rtmp,rtmpe,mms,f4m,ism,http_dash_segments,m3u8, orm3u8_native)language: Language codedynamic_range: The dynamic range of the videoformat_id: A short description of the formatformat: A human-readable description of the formatformat_note: Additional info about the formatresolution: 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 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 KBit/s. 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 streamhasaud: Gives priority to formats that have an audio streamie_pref: The format preferencelang: The language preferencequality: The quality of the formatsource: The preference of the sourceproto: 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 tovcodec,acodecvext: Video Extension (mp4>mov>webm>flv> other). If--prefer-free-formatsis used,webmis preferred.aext: Audio Extension (m4a>aac>mp3>ogg>opus>webm> other). If--prefer-free-formatsis used, the order changes toogg>opus>webm>mp3>m4a>aacext: Equivalent tovext,aextfilesize: Exact filesize, if known in advancefs_approx: Approximate filesizesize: Exact filesize if available, otherwise approximate filesizeheight: Height of videowidth: Width of videores: Video resolution, calculated as the smallest dimension.fps: Framerate of videohdr: The dynamic range of the video (DV>HDR12>HDR10+>HDR10>HLG>SDR)channels: The number of audio channelstbr: Total average bitrate in KBit/svbr: Average video bitrate in KBit/sabr: Average audio bitrate in KBit/sbr: Average bitrate in KBit/s,tbr/vbr/abrasr: Audio sample rate in Hz
Deprecation warning: Many of these fields have (currently undocumented) aliases, that may be removed in a future version. It is recommended to use only the documented field names.
All fields, unless specified otherwise, are sorted in descending order. To reverse this, prefix the field with a +. 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 behaviour can be changed by using --format-sort-force. Apart from these, the default order used is: lang,quality,res,fps,hdr:12,vcodec:vp9.2,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 has vcodec:vp9.2; i.e. av1 is not preferred. Similarly, the default for hdr is hdr:12; i.e. dolby vision is not preferred. These choices are made since DV and AV1 formats are not yet fully compatible with most devices. This may be changed in the future as more devices become capable of smoothly playing back these formats.
If your format selector is worst, the last item is selected after sorting. This means it will select the format that is worst in all respects. Most of the time, what you actually want is the video with the smallest filesize instead. So it is generally better to use -f best -S +size,+br,+res,+fps.
Tip: You can use the -v -F to see how the formats have been sorted (worst to best).
Format Selection examples
# 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.

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. Backreferences 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 to extract data from, and the format to interpret it as, separated by a colon :. Either a python regular expression with named capture groups, a single field name, or a similar syntax to the 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 viceversa. Also, any field thus created can be used in the 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_urlsto 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 tometa_descriptionfield will be added to thedescriptionfield in the file - you can use this to set a different "description" and "synopsis". To modify the metadata of individual streams, use themeta<n>_prefix (e.g.meta1_language). Any value set to themeta_field will overwrite all default values.
Note: Metadata modification happens before format selection, post-extraction and other post-processing operations. Some fields may be added or changed during these steps, overriding your changes.
For reference, these are the fields yt-dlp adds by default to the file metadata:
| Metadata fields | From |
|---|---|
title |
track or title |
date |
upload_date |
description, synopsis |
description |
purl, comment |
webpage_url |
track |
track_number |
artist |
artist, creator, uploader or uploader_id |
genre |
genre |
album |
album |
album_artist |
album_artist |
disc |
disc_number |
show |
series |
season_number |
season_number |
episode_id |
episode or episode_id |
episode_sort |
episode_number |
language of each stream |
the format's language |
Note: The file format may not support some of these fields
Modifying metadata examples
# 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=android_embedded,web;include_live_dash" --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,descriptionetc) of this language code (case-sensitive). By default, the video primary language metadata is preferred, with a fallback toentranslated. See youtube.py for list of supported content language codesskip: One or more ofhls,dashortranslated_substo skip extraction of the m3u8 manifests, dash manifests and auto-translated subtitles respectivelyplayer_client: Clients to extract video data from. The main clients areweb,androidandioswith variants_music,_embedded,_embedscreen,_creator(e.g.web_embedded); andmweb,mweb_embedscreenandtv_embedded(agegate bypass) with no variants. By default,ios,android,webis used, buttv_embeddedandcreatorvariants are added as required for age-gated videos. Similarly, the music variants are added formusic.youtube.comurls. You can useallto use all the clients, anddefaultfor the default clients.player_skip: Skip some network requests that are generally needed for robust extraction. One or more ofconfigs(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 for more detailsplayer_params: YouTube player parameters to use for player requests. Will overwrite any default ones set by yt-dlp.comment_sort:topornew(default) - choose comment sorting mode (on YouTube's side)max_comments: Limit the amount of comments to gather. Comma-separated list of integers representingmax-comments,max-parents,max-replies,max-replies-per-thread. Default isall,all,all,all- E.g.

- E.g.
formats: Change the types of formats to return.dashy(convert HTTP to DASH),duplicate(identical content but different URLs or protocol; includesdashy),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 othersinnertube_key: Innertube API key to use for all API requestsraise_incomplete_data:Incomplete Data Receivedraises an error instead of reporting a warning

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 builtin 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.
See the wiki for some known plugins
Installing Plugins
Plugins can be installed using various methods and locations.
-
Configuration directories: Plugin packages (containing a
yt_dlp_pluginsnamespace folder) can be dropped into the following standard configuration locations:- 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/
- User Plugins
-
Executable location: Plugin packages can similarly be installed in a
yt-dlp-pluginsdirectory 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/
- Binary: where
-
pip and other locations in
PYTHONPATH- Plugin packages can be installed and managed using
pip. See yt-dlp-sample-plugins for an example.- Note: plugin files between plugin packages installed with pip must have unique filenames.
- Any path in
PYTHONPATHis searched in for theyt_dlp_pluginsnamespace folder.- Note: This does not apply for Pyinstaller/py2exe builds.
- Plugin packages can be installed and managed using
.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.zipwheremypluginpkg.zipcontainsyt_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 repo for a template plugin package and the 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 repectively. 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 as a topic to your repository for discoverability.
See the 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:
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 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 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
