140 ## UPDATE
141 You can use `yt-dlp -U` to update if you are using the [release binaries](#release-files)
143 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
145 For other third-party package managers, see [the wiki](https://github.com/yt-dlp/yt-dlp/wiki/Installation#third-party-package-managers) or refer their documentation
147 <a id="update-channels"></a>
149 There are currently three release channels for binaries: `stable`, `nightly` and `master`.
151 * `stable` is the default channel, and many of its changes have been tested by users of the `nightly` and `master` channels.
152 * 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).
153 * 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).
155 When using `--update`/`-U`, a release binary will only update to its current channel.
156 `--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.
158 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.
160 Example usage:
161 * `yt-dlp --update-to master` switch to the `master` channel and update to its latest release
162 * `yt-dlp --update-to stable@2023.07.06` upgrade/downgrade to release to `stable` channel tag `2023.07.06`
163 * `yt-dlp --update-to 2023.10.07` upgrade/downgrade to tag `2023.10.07` if it exists on the current channel
164 * `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`
166 **Important**: Any user experiencing an issue with the `stable` release should install or update to the `nightly` release before submitting a bug report:
167 ```
168 # To update to nightly from stable executable/binary:
169 yt-dlp --update-to nightly
171 # To install nightly with pip:
172 python3 -m pip install -U --pre yt-dlp[default]
173 ```
175 ## DEPENDENCIES
176 Python versions 3.8+ (CPython and PyPy) are supported. Other versions and implementations may or may not work correctly.
178 <!-- Python 3.5+ uses VC++14 and it is already embedded in the binary created
179 <!x-- https://www.microsoft.com/en-us/download/details.aspx?id=26999 --x>
180 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.
181 -->
183 While all the other dependencies are optional, `ffmpeg` and `ffprobe` are highly recommended
185 ### Strongly recommended
187 * [**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)
189 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
191 **Important**: What you need is ffmpeg *binary*, **NOT** [the Python package of the same name](https://pypi.org/project/ffmpeg)

228 To use or redistribute the dependencies, you must agree to their respective licensing terms.
230 The standalone release binaries are built with the Python interpreter and the packages marked with **\*** included.
232 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
235 ## COMPILE
237 ### Standalone PyInstaller Builds
238 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.
240 You can run the following commands:
242 ```
243 python3 devscripts/install_deps.py --include pyinstaller
244 python3 devscripts/make_lazy_extractors.py
245 python3 -m bundle.pyinstaller
246 ```
248 On some systems, you may need to use `py` or `python` instead of `python3`.
250 `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).
252 **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.
254 **Important**: Running `pyinstaller` directly **instead of** using `python -m bundle.pyinstaller` is **not** officially supported. This may or may not work correctly.
256 ### Platform-independent Binary (UNIX)
257 You will need the build tools `python` (3.8+), `zip`, `make` (GNU), `pandoc`\* and `pytest`\*.
259 After installing these, simply run `make`.
261 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)
263 ### Standalone Py2Exe Builds (Windows)
265 While we provide the option to build with [py2exe](https://www.py2exe.org), it is recommended to build [using PyInstaller](#standalone-pyinstaller-builds) instead since the py2exe builds **cannot contain `pycryptodomex`/`certifi` and needs VC++14** on the target computer to run.
267 If you wish to build it anyway, install Python (if it is not already installed) and you can run the following commands:
269 ```
270 py devscripts/install_deps.py --include py2exe
271 py devscripts/make_lazy_extractors.py
272 py -m bundle.py2exe
273 ```
275 ### Related scripts
277 * **`devscripts/install_deps.py`** - Install dependencies for yt-dlp.
278 * **`devscripts/update-version.py`** - Update the version number based on current date.
279 * **`devscripts/set-variant.py`** - Set the build variant of the executable.
280 * **`devscripts/make_changelog.py`** - Create a markdown changelog using short commit messages and update `CONTRIBUTORS` file.
281 * **`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=1` if you wish to forcefully disable lazy extractor loading.
283 Note: See their `--help` for more info.
285 ### Forking the project
286 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.
288 # USAGE AND OPTIONS
290 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
291 yt-dlp [OPTIONS] [--] URL [URL...]
293 `Ctrl+F` is your friend :D
294 <!-- MANPAGE: END EXCLUDED SECTION -->
296 <!-- Auto generated -->
297 ## General Options:
298 -h, --help Print this help text and exit
299 --version Print program version and exit
300 -U, --update Update this program to the latest version
301 --no-update Do not check for updates (default)
302 --update-to [CHANNEL]@[TAG] Upgrade/downgrade to a specific version.
303 CHANNEL can be a repository as well. CHANNEL
304 and TAG default to "stable" and "latest"
305 respectively if omitted; See "UPDATE" for
306 details. Supported channels: stable,
307 nightly, master
308 -i, --ignore-errors Ignore download and postprocessing errors.
309 The download will be considered successful
310 even if the postprocessing fails
311 --no-abort-on-error Continue with next video on download errors;
312 e.g. to skip unavailable videos in a
313 playlist (default)
314 --abort-on-error Abort downloading of further videos if an
315 error occurs (Alias: --no-ignore-errors)
316 --dump-user-agent Display the current user-agent and exit
317 --list-extractors List all supported extractors and exit
318 --extractor-descriptions Output descriptions of all supported
319 extractors and exit
320 --use-extractors NAMES Extractor names to use separated by commas.
321 You can also use regexes, "all", "default"
322 and "end" (end URL matching); e.g. --ies
323 "holodex.*,end,youtube". Prefix the name
324 with a "-" to exclude it, e.g. --ies
325 default,-generic. Use --list-extractors for
326 a list of extractor names. (Alias: --ies)
327 --default-search PREFIX Use this prefix for unqualified URLs. E.g.
328 "gvsearch2:python" downloads two videos from
329 google videos for the search term "python".
330 Use the value "auto" to let yt-dlp guess
331 ("auto_warning" to emit a warning when
332 guessing). "error" just throws an error. The
333 default value "fixup_error" repairs broken
334 URLs, but emits an error if this is not
335 possible instead of searching
336 --ignore-config Don't load any more configuration files
337 except those given to --config-locations.
338 For backward compatibility, if this option
339 is found inside the system configuration
340 file, the user configuration is not loaded.
341 (Alias: --no-config)

367 optionally prefixed by the STREAM (stdout or
368 stderr) to apply the setting to. Can be one
369 of "always", "auto" (default), "never", or
370 "no_color" (use non color terminal
371 sequences). Can be used multiple times
372 --compat-options OPTS Options that can help keep compatibility
373 with youtube-dl or youtube-dlc
374 configurations by reverting some of the
375 changes made in yt-dlp. See "Differences in
376 default behavior" for details
377 --alias ALIASES OPTIONS Create aliases for an option string. Unless
378 an alias starts with a dash "-", it is
379 prefixed with "--". Arguments are parsed
380 according to the Python string formatting
381 mini-language. E.g. --alias get-audio,-X
382 "-S=aext:{0},abr -x --audio-format {0}"
383 creates options "--get-audio" and "-X" that
384 takes an argument (ARG0) and expands to
385 "-S=aext:ARG0,abr -x --audio-format ARG0".
386 All defined aliases are listed in the --help
387 output. Alias options can trigger more
388 aliases; so be careful to avoid defining
389 recursive options. As a safety measure, each
390 alias may be triggered a maximum of 100
391 times. This option can be used multiple times
393 ## Network Options:
394 --proxy URL Use the specified HTTP/HTTPS/SOCKS proxy. To
395 enable SOCKS proxy, specify a proper scheme,
396 e.g. socks5://user:pass@127.0.0.1:1080/.
397 Pass in an empty string (--proxy "") for
398 direct connection
399 --socket-timeout SECONDS Time to wait before giving up, in seconds
400 --source-address IP Client-side IP address to bind to
401 --impersonate CLIENT[:OS] Client to impersonate for requests. E.g.
402 chrome, chrome-110, chrome:windows-10. Pass
403 --impersonate="" to impersonate any client.
404 --list-impersonate-targets List available clients to impersonate.
405 -4, --force-ipv4 Make all connections via IPv4
406 -6, --force-ipv6 Make all connections via IPv6
407 --enable-file-urls Enable file:// URLs. This is disabled by
408 default for security reasons.
410 ## Geo-restriction:
411 --geo-verification-proxy URL Use this proxy to verify the IP address for
412 some geo-restricted sites. The default proxy
413 specified by --proxy (or none, if the option
414 is not present) is used for the actual
415 downloading
416 --xff VALUE How to fake X-Forwarded-For HTTP header to
417 try bypassing geographic restriction. One of
418 "default" (only when known to be useful),
419 "never", an IP block in CIDR notation, or a
420 two-letter ISO 3166-2 country code
422 ## Video Selection:
423 -I, --playlist-items ITEM_SPEC Comma separated playlist_index of the items
424 to download. You can specify a range using
425 "[START]:[STOP][:STEP]". For backward
426 compatibility, START-STOP is also supported.
427 Use negative indices to count from the right
428 and negative STEP to download in reverse
429 order. E.g. "-I 1:3,7,-5::2" used on a
430 playlist of size 15 will download the items
431 at index 1,2,3,7,11,13,15
432 --min-filesize SIZE Abort download if filesize is smaller than
433 SIZE, e.g. 50k or 44.6M
434 --max-filesize SIZE Abort download if filesize is larger than
435 SIZE, e.g. 50k or 44.6M
436 --date DATE Download only videos uploaded on this date.
437 The date can be "YYYYMMDD" or in the format
438 [now|today|yesterday][-N[day|week|month|year]].
439 E.g. "--date today-2weeks" downloads only
440 videos uploaded on the same day two weeks ago
441 --datebefore DATE Download only videos uploaded on or before
442 this date. The date formats accepted is the
443 same as --date
444 --dateafter DATE Download only videos uploaded on or after
445 this date. The date formats accepted is the
446 same as --date
447 --match-filters FILTER Generic video filter. Any "OUTPUT TEMPLATE"
448 field can be compared with a number or a
449 string using the operators defined in
450 "Filtering Formats". You can also simply
451 specify a field to match if the field is
452 present, use "!field" to check if the field
453 is not present, and "&" to check multiple
454 conditions. Use a "\" to escape "&" or
455 quotes if needed. If used multiple times,
456 the filter matches if atleast one of the
457 conditions are met. E.g. --match-filter
458 !is_live --match-filter "like_count>?100 &
459 description~='(?i)\bcats \& dogs\b'" matches
460 only videos that are not live OR those that
461 have a like count more than 100 (or the like
462 field is not available) and also has a
463 description that contains the phrase "cats &

883 used. (currently supported: best (default),
884 aac, alac, flac, m4a, mp3, opus, vorbis,
885 wav). You can specify multiple rules using
886 similar syntax as --remux-video
887 --audio-quality QUALITY Specify ffmpeg audio quality to use when
888 converting the audio with -x. Insert a value
889 between 0 (best) and 10 (worst) for VBR or a

893 gif, mkv, mov, mp4, webm, aac, aiff, alac,
894 flac, m4a, mka, mp3, ogg, opus, vorbis,
895 wav). If target container does not support
896 the video/audio codec, remuxing will fail.
897 You can specify multiple rules; e.g.
898 "aac>m4a/mov>mp4/mkv" will remux aac to m4a,
899 mov to mp4 and anything else to mkv
900 --recode-video FORMAT Re-encode the video into another format if

915 FFmpeg and FFprobe. You can also specify
916 "PP+EXE:ARGS" to give the arguments to the
917 specified executable only when being used by
918 the specified postprocessor. Additionally,
919 for ffmpeg/ffprobe, "_i"/"_o" can be
920 appended to the prefix optionally followed
921 by a number to pass the argument before the
922 specified input/output file, e.g. --ppa
923 "Merger+ffmpeg_i1:-v quiet". You can use
924 this option multiple times to give different
925 arguments to different postprocessors.

955 for details. Supported values of "WHEN" are
956 the same as that of --use-postprocessor
957 (default: pre_process)
958 --replace-in-metadata [WHEN:]FIELDS REGEX REPLACE
959 Replace text in a metadata field using the
960 given regex. This option can be used
961 multiple times. Supported values of "WHEN"

964 --xattrs Write metadata to the video file's xattrs
965 (using dublin core and xdg standards)
966 --concat-playlist POLICY Concatenate videos in a playlist. One of
967 "never", "always", or "multi_video"
968 (default; only when the videos form a single
969 show). All the video files must have same
970 codecs and number of streams to be
971 concatable. The "pl_video:" prefix can be
972 used with "--paths" and "--output" to set
973 the output filename for the concatenated
974 files. See "OUTPUT TEMPLATE" for details
975 --fixup POLICY Automatically correct known faults of the
976 file. One of never (do nothing), warn (only
977 emit a warning), detect_or_warn (the
978 default; fix file if we can, warn
979 otherwise), force (try fixing even if file
980 already exists)
981 --ffmpeg-location PATH Location of the ffmpeg binary; either the
982 path to the binary or its containing directory

984 when to execute it, separated by a ":".
985 Supported values of "WHEN" are the same as
986 that of --use-postprocessor (default:
987 after_move). Same syntax as the output
988 template can be used to pass any field as
989 arguments to the command. If no fields are
990 passed, %(filepath,_filename|)q is appended
991 to the end of the command. This option can
992 be used multiple times
993 --no-exec Remove any previously defined --exec
994 --convert-subs FORMAT Convert the subtitles to another format
995 (currently supported: ass, lrc, srt, vtt)
996 (Alias: --convert-subtitles)

999 can specify multiple rules using similar
1000 syntax as --remux-video
1001 --split-chapters Split video into multiple files based on
1002 internal chapters. The "chapter:" prefix can
1003 be used with "--paths" and "--output" to set
1004 the output filename for the split files. See
1005 "OUTPUT TEMPLATE" for details
1006 --no-split-chapters Do not split video based on chapters (default)
1007 --remove-chapters REGEX Remove chapters whose title matches the
1008 given regular expression. The syntax is the
1009 same as --download-sections. This option can
1010 be used multiple times

1012 (default)
1013 --force-keyframes-at-cuts Force keyframes at cuts when
1014 downloading/splitting/removing sections.
1015 This is slow due to needing a re-encode, but
1016 the resulting video may have fewer artifacts
1017 around the cuts
1018 --no-force-keyframes-at-cuts Do not force keyframes around the chapters
1019 when cutting/splitting (default)
1020 --use-postprocessor NAME[:ARGS]
1021 The (case sensitive) name of plugin
1022 postprocessors to be enabled, and
1023 (optionally) arguments to be passed to it,
1024 separated by a colon ":". ARGS are a
1025 semicolon ";" delimited list of NAME=VALUE.
1026 The "when" argument determines when the
1027 postprocessor is invoked. It can be one of
1028 "pre_process" (after video extraction),
1029 "after_filter" (after video passes filter),
1030 "video" (after --format; before
1031 --print/--output), "before_dl" (before each
1032 video download), "post_process" (after each
1033 video download; default), "after_move"
1034 (after moving video file to it's final
1035 locations), "after_video" (after downloading
1036 and processing all formats of a video), or
1037 "playlist" (at end of playlist). This option
1038 can be used multiple times to add different
1039 postprocessors
1041 ## SponsorBlock Options:
1042 Make chapter entries for, or remove various segments (sponsor,
1043 introductions, etc.) from downloaded YouTube videos using the
1044 [SponsorBlock API](https://sponsor.ajay.app)

1056 --sponsorblock-remove CATS SponsorBlock categories to be removed from
1057 the video file, separated by commas. If a
1058 category is present in both mark and remove,
1059 remove takes precedence. The syntax and
1060 available categories are the same as for
1061 --sponsorblock-mark except that "default"
1062 refers to "all,-filler" and poi_highlight,
1063 chapter are not available
1064 --sponsorblock-chapter-title TEMPLATE

1087 (default)
1088 --extractor-args IE_KEY:ARGS Pass ARGS arguments to the IE_KEY extractor.
1089 See "EXTRACTOR ARGUMENTS" for details. You
1090 can use this option multiple times to give
1091 arguments for different extractors
1093 # CONFIGURATION
1095 You can configure yt-dlp by placing any supported command line option to a configuration file. The configuration is loaded from the following locations:
1097 1. **Main Configuration**:
1098 * The file given to `--config-location`
1099 1. **Portable Configuration**: (Recommended for portable installations)
1100 * If using a binary, `yt-dlp.conf` in the same directory as the binary
1101 * If running from source-code, `yt-dlp.conf` in the parent directory of `yt_dlp`
1102 1. **Home Configuration**:
1103 * `yt-dlp.conf` in the home path given to `-P`
1104 * If `-P` is not given, the current directory is searched
1105 1. **User Configuration**:
1106 * `${XDG_CONFIG_HOME}/yt-dlp.conf`
1107 * `${XDG_CONFIG_HOME}/yt-dlp/config` (recommended on Linux/macOS)
1108 * `${XDG_CONFIG_HOME}/yt-dlp/config.txt`
1109 * `${APPDATA}/yt-dlp.conf`
1110 * `${APPDATA}/yt-dlp/config` (recommended on Windows)
1111 * `${APPDATA}/yt-dlp/config.txt`
1112 * `~/yt-dlp.conf`
1113 * `~/yt-dlp.conf.txt`
1114 * `~/.yt-dlp/config`
1115 * `~/.yt-dlp/config.txt`
1117 See also: [Notes about environment variables](#notes-about-environment-variables)
1118 1. **System Configuration**:
1119 * `/etc/yt-dlp.conf`
1120 * `/etc/yt-dlp/config`
1121 * `/etc/yt-dlp/config.txt`
1123 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:
1124 ```
1125 # Lines starting with # are comments
1127 # Always extract audio
1128 -x
1130 # Do not copy the mtime
1131 --no-mtime
1133 # Use this proxy
1134 --proxy 127.0.0.1:3128
1136 # Save all videos under YouTube directory in your home directory
1137 -o ~/YouTube/%(title)s.%(ext)s
1138 ```
1140 **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.
1142 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.
1144 ### Configuration file encoding
1146 The configuration files are decoded according to the UTF BOM if present, and in the encoding from system locale otherwise.
1148 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.
1150 ### Authentication with netrc
1152 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:
1153 ```
1154 touch ${HOME}/.netrc
1155 chmod a-rwx,u+rw ${HOME}/.netrc
1156 ```
1157 After that you can add credentials for an extractor in the following format, where *extractor* is the name of the extractor in lowercase:
1158 ```
1159 machine <extractor> login <username> password <password>
1160 ```
1161 E.g.
1162 ```
1163 machine youtube login myaccount@gmail.com password my_youtube_password
1164 machine twitch login my_twitch_account_name password my_twitch_password
1165 ```
1166 To activate authentication with the `.netrc` file you should pass `--netrc` to yt-dlp or place it in the [configuration file](#configuration).
1168 The default location of the .netrc file is `~` (see below).
1170 As an alternative to using the `.netrc` file, which has the disadvantage of keeping your passwords in a plain text file, you can configure a custom shell command to provide the credentials for an extractor. This is done by providing the `--netrc-cmd` parameter, it shall output the credentials in the netrc format and return `0` on success, other values will be treated as an error. `{}` in the command will be replaced by the name of the extractor to make it possible to select the credentials for the right extractor.
1172 E.g. To use an encrypted `.netrc` file stored as `.authinfo.gpg`
1173 ```
1174 yt-dlp --netrc-cmd 'gpg --decrypt ~/.authinfo.gpg' https://www.youtube.com/watch?v=BaW_jenozKc
1175 ```
1178 ### Notes about environment variables
1179 * Environment variables are normally specified as `${VARIABLE}`/`$VARIABLE` on UNIX and `%VARIABLE%` on Windows; but is always shown as `${VARIABLE}` in this documentation
1180 * yt-dlp also allow using UNIX-style variables on Windows for path-like options; e.g. `--output`, `--config-location`
1181 * If unset, `${XDG_CONFIG_HOME}` defaults to `~/.config` and `${XDG_CACHE_HOME}` to `~/.cache`
1182 * On Windows, `~` points to `${HOME}` if present; or, `${USERPROFILE}` or `${HOMEDRIVE}${HOMEPATH}` otherwise
1183 * On Windows, `${USERPROFILE}` generally points to `C:\Users\<user name>` and `${APPDATA}` to `${USERPROFILE}\AppData\Roaming`
1185 # OUTPUT TEMPLATE
1187 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.
1189 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
1190 **tl;dr:** [navigate me to examples](#output-template-examples).
1191 <!-- MANPAGE: END EXCLUDED SECTION -->
1193 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).
1195 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.
1197 The field names themselves (the part inside the parenthesis) can also have some special formatting:
1199 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:-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
1201 1. **Arithmetic**: Simple arithmetic can be done on numeric fields using `+`, `-` and `*`. E.g. `%(playlist_index+10)03d`, `%(n_entries+1-playlist_index)d`
1203 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`
1205 1. **Alternatives**: Alternate fields can be specified separated with a `,`. E.g. `%(release_date>%Y,upload_date>%Y|Unknown)s`
1207 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`
1209 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`
1211 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)
1213 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
1215 To summarize, the general syntax for a field is:
1216 ```
1217 %(name[.keys][addition][>strf][,alternate][&replacement][|default])[flags][width][.precision][length]type
1218 ```
1220 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.
1222 <a id="outtmpl-postprocess-note"></a>
1224 **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.

1360 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.
1362 **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).
1364 **Tip**: Look at the `-j` output to identify which fields are available for the particular URL
1366 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`.
1368 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.
1370 To use percent literals in an output template use `%%`. To output to stdout use `-o -`.
1372 The current default template is `%(title)s [%(id)s].%(ext)s`.
1374 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.

1413 # Stream the video being downloaded to stdout
1414 $ yt-dlp -o - BaW_jenozKc
1415 ```
1417 # FORMAT SELECTION
1419 By default, yt-dlp tries to download the best available quality if you **don't** pass any options.
1420 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`.
1422 **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.
1424 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.
1426 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
1427 **tl;dr:** [navigate me to examples](#format-selection-examples).
1428 <!-- MANPAGE: END EXCLUDED SECTION -->
1430 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.
1432 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.
1434 You can use `-f -` to interactively provide the format selector *for each video*
1436 You can also use special names to select particular edge case formats:
1438 - `all`: Select **all formats** separately
1439 - `mergeall`: Select and **merge all formats** (Must be used with `--audio-multistreams`, `--video-multistreams` or both)
1440 - `b*`, `best*`: Select the best quality format that **contains either** a video or an audio or both (ie; `vcodec!=none or acodec!=none`)
1441 - `b`, `best`: Select the best quality format that **contains both** video and audio. Equivalent to `best*[vcodec!=none][acodec!=none]`
1442 - `bv`, `bestvideo`: Select the best quality **video-only** format. Equivalent to `best*[acodec=none]`
1443 - `bv*`, `bestvideo*`: Select the best quality format that **contains video**. It may also contain audio. Equivalent to `best*[vcodec!=none]`
1444 - `ba`, `bestaudio`: Select the best quality **audio-only** format. Equivalent to `best*[vcodec=none]`
1445 - `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))
1446 - `w*`, `worst*`: Select the worst quality format that contains either a video or an audio
1447 - `w`, `worst`: Select the worst quality format that contains both video and audio. Equivalent to `worst*[vcodec!=none][acodec!=none]`
1448 - `wv`, `worstvideo`: Select the worst quality video-only format. Equivalent to `worst*[acodec=none]`
1449 - `wv*`, `worstvideo*`: Select the worst quality format that contains video. It may also contain audio. Equivalent to `worst*[vcodec!=none]`
1450 - `wa`, `worstaudio`: Select the worst quality audio-only format. Equivalent to `worst*[vcodec=none]`
1451 - `wa*`, `worstaudio*`: Select the worst quality format that contains audio. It may also contain video. Equivalent to `worst*[acodec!=none]`
1453 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.
1455 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.
1457 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.
1459 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`.
1461 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.
1463 **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
1465 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`.
1467 ## Filtering Formats
1469 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`).
1471 The following numeric meta fields can be used with comparisons `<`, `<=`, `>`, `>=`, `=` (equals), `!=` (not equals):
1473 - `filesize`: The number of bytes, if known in advance
1474 - `filesize_approx`: An estimate for the number of bytes
1475 - `width`: Width of the video, if known
1476 - `height`: Height of the video, if known
1477 - `aspect_ratio`: Aspect ratio of the video, if known
1478 - `tbr`: Average bitrate of audio and video in [kbps](## "1000 bits/sec")
1479 - `abr`: Average audio bitrate in [kbps](## "1000 bits/sec")
1480 - `vbr`: Average video bitrate in [kbps](## "1000 bits/sec")
1481 - `asr`: Audio sampling rate in Hertz
1482 - `fps`: Frame rate
1483 - `audio_channels`: The number of audio channels
1484 - `stretched_ratio`: `width:height` of the video's pixels, if not square
1486 Also filtering work for comparisons `=` (equals), `^=` (starts with), `$=` (ends with), `*=` (contains), `~=` (matches regex) and following string meta fields:
1488 - `url`: Video URL
1489 - `ext`: File extension
1490 - `acodec`: Name of the audio codec in use
1491 - `vcodec`: Name of the video codec in use
1492 - `container`: Name of the container format
1493 - `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`)
1494 - `language`: Language code
1495 - `dynamic_range`: The dynamic range of the video
1496 - `format_id`: A short description of the format
1497 - `format`: A human-readable description of the format
1498 - `format_note`: Additional info about the format
1499 - `resolution`: Textual description of width and height
1501 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 `._-`.
1503 **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.
1505 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.
1507 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.
1509 ## Sorting Formats
1511 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...`.
1513 The available fields are:
1515 - `hasvid`: Gives priority to formats that have a video stream
1516 - `hasaud`: Gives priority to formats that have an audio stream
1517 - `ie_pref`: The format preference
1518 - `lang`: The language preference
1519 - `quality`: The quality of the format
1520 - `source`: The preference of the source
1521 - `proto`: Protocol used for download (`https`/`ftps` > `http`/`ftp` > `m3u8_native`/`m3u8` > `http_dash_segments`> `websocket_frag` > `mms`/`rtsp` > `f4f`/`f4m`)
1522 - `vcodec`: Video Codec (`av01` > `vp9.2` > `vp9` > `h265` > `h264` > `vp8` > `h263` > `theora` > other)
1523 - `acodec`: Audio Codec (`flac`/`alac` > `wav`/`aiff` > `opus` > `vorbis` > `aac` > `mp4a` > `mp3` > `ac4` > `eac3` > `ac3` > `dts` > other)
1524 - `codec`: Equivalent to `vcodec,acodec`
1525 - `vext`: Video Extension (`mp4` > `mov` > `webm` > `flv` > other). If `--prefer-free-formats` is used, `webm` is preferred.
1526 - `aext`: Audio Extension (`m4a` > `aac` > `mp3` > `ogg` > `opus` > `webm` > other). If `--prefer-free-formats` is used, the order changes to `ogg` > `opus` > `webm` > `mp3` > `m4a` > `aac`
1527 - `ext`: Equivalent to `vext,aext`
1528 - `filesize`: Exact filesize, if known in advance
1529 - `fs_approx`: Approximate filesize
1530 - `size`: Exact filesize if available, otherwise approximate filesize
1531 - `height`: Height of video
1532 - `width`: Width of video
1533 - `res`: Video resolution, calculated as the smallest dimension.
1534 - `fps`: Framerate of video
1535 - `hdr`: The dynamic range of the video (`DV` > `HDR12` > `HDR10+` > `HDR10` > `HLG` > `SDR`)
1536 - `channels`: The number of audio channels
1537 - `tbr`: Total average bitrate in [kbps](## "1000 bits/sec")
1538 - `vbr`: Average video bitrate in [kbps](## "1000 bits/sec")
1539 - `abr`: Average audio bitrate in [kbps](## "1000 bits/sec")
1540 - `br`: Average bitrate in [kbps](## "1000 bits/sec"), `tbr`/`vbr`/`abr`
1541 - `asr`: Audio sample rate in Hz
1543 **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.
1545 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.
1547 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.
1549 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.
1551 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`.
1553 **Tip**: You can use the `-v -F` to see how the formats have been sorted (worst to best).
1555 ## Format Selection examples
1557 ```bash
1558 # Download and merge the best video-only format and the best audio-only format,
1559 # or download the best combined format if video-only format is not available
1560 $ yt-dlp -f "bv+ba/b"
1562 # Download best format that contains video,
1563 # and if it doesn't already have an audio stream, merge it with best audio-only format
1564 $ yt-dlp -f "bv*+ba/b"
1566 # Same as above
1567 $ yt-dlp
1569 # Download the best video-only format and the best audio-only format without merging them
1570 # For this case, an output template should be used since
1571 # by default, bestvideo and bestaudio will have the same file name.
1572 $ yt-dlp -f "bv,ba" -o "%(title)s.f%(format_id)s.%(ext)s"
1574 # Download and merge the best format that has a video stream,
1575 # and all audio-only formats into one file

1676 ```
1678 # MODIFYING METADATA
1680 The metadata obtained by the extractors can be modified by using `--parse-metadata` and `--replace-in-metadata`
1682 `--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.
1684 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.
1686 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](#output-template) and will also affect the media file's metadata added when using `--embed-metadata`.
1688 This option also has a few special uses:
1690 * 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
1692 * 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.
1694 **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.
1696 For reference, these are the fields yt-dlp adds by default to the file metadata:
1698 Metadata fields | From
1699 :--------------------------|:------------------------------------------------
1700 `title` | `track` or `title`
1701 `date` | `upload_date`
1702 `description`, `synopsis` | `description`
1703 `purl`, `comment` | `webpage_url`
1704 `track` | `track_number`
1705 `artist` | `artist`, `artists`, `creator`, `creators`, `uploader` or `uploader_id`
1706 `composer` | `composer` or `composers`
1707 `genre` | `genre` or `genres`
1708 `album` | `album`
1709 `album_artist` | `album_artist` or `album_artists`
1710 `disc` | `disc_number`
1711 `show` | `series`
1712 `season_number` | `season_number`
1713 `episode_id` | `episode` or `episode_id`
1714 `episode_sort` | `episode_number`
1715 `language` of each stream | the format's `language`
1717 **Note**: The file format may not support some of these fields
1720 ## Modifying metadata examples
1722 ```bash
1723 # Interpret the title as "Artist - Title"
1724 $ yt-dlp --parse-metadata "title:%(artist)s - %(title)s"
1726 # Regex example
1727 $ yt-dlp --parse-metadata "description:Artist - (?P<artist>.+)"
1729 # Set title as "Series name S01E05"
1730 $ yt-dlp --parse-metadata "%(series)s S%(season_number)02dE%(episode_number)02d:%(title)s"
1732 # Prioritize uploader as the "artist" field in video metadata
1733 $ yt-dlp --parse-metadata "%(uploader|)s:%(meta_artist)s" --embed-metadata
1735 # Set "comment" field in video metadata using description instead of webpage_url,
1736 # handling multiple lines correctly
1737 $ yt-dlp --parse-metadata "description:(?s)(?P<meta_comment>.+)" --embed-metadata
1739 # Do not set any "synopsis" in the video metadata
1740 $ yt-dlp --parse-metadata ":(?P<meta_synopsis>)"
1742 # Remove "formats" field from the infojson by setting it to an empty string
1743 $ yt-dlp --parse-metadata "video::(?P<formats>)" --write-info-json
1745 # Replace all spaces and "_" in title and uploader with a `-`
1746 $ yt-dlp --replace-in-metadata "title,uploader" "[ _]" "-"
1748 ```
1750 # EXTRACTOR ARGUMENTS
1752 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"`
1754 Note: In CLI, `ARG` can use `-` instead of `_`; e.g. `youtube:player-client"` becomes `youtube:player_client"`
1756 The following extractors use this feature:
1758 #### youtube
1759 * `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
1760 * `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
1761 * `player_client`: Clients to extract video data from. The main clients are `web`, `android` and `ios` with variants `_music`, `_embedded`, `_embedscreen`, `_creator` (e.g. `web_embedded`); and `mweb`, `mweb_embedscreen` and `tv_embedded` (agegate bypass) with no variants. By default, `ios,android,web` is used, but `tv_embedded` and `creator` variants are added as required for age-gated videos. Similarly, the music variants are added for `music.youtube.com` urls. You can use `all` to use all the clients, and `default` for the default clients.
1762 * `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
1763 * `player_params`: YouTube player parameters to use for player requests. Will overwrite any default ones set by yt-dlp.
1764 * `comment_sort`: `top` or `new` (default) - choose comment sorting mode (on YouTube's side)
1765 * `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`
1766 * 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
1767 * `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)
1768 * `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
1769 * `innertube_key`: Innertube API key to use for all API requests
1770 * `raise_incomplete_data`: `Incomplete Data Received` raises an error instead of reporting a warning
1772 #### youtubetab (YouTube playlists, channels, feeds, etc.)
1773 * `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)
1774 * `approximate_date`: Extract approximate `upload_date` and `timestamp` in flat-playlist. This may cause date-based filters to be slightly off
1776 #### generic
1777 * `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`. Does not apply to ffmpeg
1778 * `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`
1779 * `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
1780 * `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`
1782 #### funimation
1783 * `language`: Audio languages to extract, e.g. `funimation:language=english,japanese`
1784 * `version`: The video version to extract - `uncut` or `simulcast`
1786 #### crunchyrollbeta (Crunchyroll)
1787 * `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`
1789 #### vikichannel
1790 * `video_types`: Types of videos to download - one or more of `episodes`, `movies`, `clips`, `trailers`
1792 #### niconico
1793 * `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.**
1795 #### youtubewebarchive
1796 * `check_all`: Try to check more at the cost of more requests. One or more of `thumbnails`, `captures`
1798 #### gamejolt
1799 * `comment_sort`: `hot` (default), `you` (cookies needed), `top`, `new` - choose comment sorting mode (on GameJolt's side)
1801 #### hotstar
1802 * `res`: resolution to ignore - one or more of `sd`, `hd`, `fhd`
1803 * `vcodec`: vcodec to ignore - one or more of `h264`, `h265`, `dvh265`
1804 * `dr`: dynamic range to ignore - one or more of `sdr`, `hdr10`, `dv`
1806 #### niconicochannelplus
1807 * `max_comments`: Maximum number of comments to extract - default is `120`
1809 #### tiktok
1810 * `api_hostname`: Hostname to use for mobile API calls, e.g. `api22-normal-c-alisg.tiktokv.com`
1811 * `app_name`: Default app name to use with mobile API calls, e.g. `trill`
1812 * `app_version`: Default app version to use with mobile API calls - should be set along with `manifest_app_version`, e.g. `34.1.2`
1813 * `manifest_app_version`: Default numeric app version to use with mobile API calls, e.g. `2023401020`
1814 * `aid`: Default app ID to use with API calls, e.g. `1180`
1815 * `app_info`: 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`
1817 #### rokfinchannel
1818 * `tab`: Which tab to download - one of `new`, `top`, `videos`, `podcasts`, `streams`, `stacks`
1820 #### twitter
1821 * `api`: Select one of `graphql` (default), `legacy` or `syndication` as the API for tweet extraction. Has no effect if logged in
1823 #### stacommu, wrestleuniverse
1824 * `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
1826 #### twitch

1843 # PLUGINS
1845 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!**
1847 Plugins can be of `<type>`s `extractor` or `postprocessor`.
1848 - Extractor plugins do not need to be enabled from the CLI and are automatically invoked when the input URL is suitable for it.
1849 - Extractor plugins take priority over builtin extractors.
1850 - Postprocessor plugins can be invoked using `--use-postprocessor NAME`.
1853 Plugins are loaded from the namespace packages `yt_dlp_plugins.extractor` and `yt_dlp_plugins.postprocessor`.
1855 In other words, the file structure on the disk looks something like:
1857 yt_dlp_plugins/
1858 extractor/
1859 myplugin.py
1860 postprocessor/
1861 myplugin.py
1863 yt-dlp looks for these `yt_dlp_plugins` namespace folders in many locations (see below) and loads in plugins from **all** of them.
1865 See the [wiki for some known plugins](https://github.com/yt-dlp/yt-dlp/wiki/Plugins)
1867 ## Installing Plugins
1869 Plugins can be installed using various methods and locations.
1871 1. **Configuration directories**:
1872 Plugin packages (containing a `yt_dlp_plugins` namespace folder) can be dropped into the following standard [configuration locations](#configuration):
1873 * **User Plugins**
1874 * `${XDG_CONFIG_HOME}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Linux/macOS)
1875 * `${XDG_CONFIG_HOME}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1876 * `${APPDATA}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Windows)
1877 * `${APPDATA}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1878 * `~/.yt-dlp/plugins/<package name>/yt_dlp_plugins/`
1879 * `~/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1880 * **System Plugins**
1881 * `/etc/yt-dlp/plugins/<package name>/yt_dlp_plugins/`
1882 * `/etc/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1883 2. **Executable location**: Plugin packages can similarly be installed in a `yt-dlp-plugins` directory under the executable location (recommended for portable installations):
1884 * Binary: where `<root-dir>/yt-dlp.exe`, `<root-dir>/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1885 * Source: where `<root-dir>/yt_dlp/__main__.py`, `<root-dir>/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1887 3. **pip and other locations in `PYTHONPATH`**
1888 * 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.
1889 * Note: plugin files between plugin packages installed with pip must have unique filenames.
1890 * Any path in `PYTHONPATH` is searched in for the `yt_dlp_plugins` namespace folder.
1891 * Note: This does not apply for Pyinstaller/py2exe builds.
1894 `.zip`, `.egg` and `.whl` archives containing a `yt_dlp_plugins` namespace folder in their root are also supported as plugin packages.
1895 * e.g. `${XDG_CONFIG_HOME}/yt-dlp/plugins/mypluginpkg.zip` where `mypluginpkg.zip` contains `yt_dlp_plugins/<type>/myplugin.py`
1897 Run yt-dlp with `--verbose` to check if the plugin has been loaded.
1899 ## Developing Plugins
1901 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.
1903 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`).
1905 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.
1907 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.
1909 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.
1911 # EMBEDDING YT-DLP
1913 yt-dlp makes the best effort to be a good command-line program, and thus should be callable from any programming language.
1915 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.
1917 From a Python program, you can embed yt-dlp in a more powerful fashion, like this:
1919 ```python
1920 from yt_dlp import YoutubeDL
1922 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
1923 with YoutubeDL() as ydl:
1924 ydl.download(URLS)
1925 ```
1927 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.
1929 **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)
1931 ## Embedding examples
1933 #### Extracting information
1935 ```python
1936 import json
1937 import yt_dlp
1939 URL = 'https://www.youtube.com/watch?v=BaW_jenozKc'
1941 # ℹ️ See help(yt_dlp.YoutubeDL) for a list of available options and public functions
1942 ydl_opts = {}
1943 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
1944 info = ydl.extract_info(URL, download=False)
1946 # ℹ️ ydl.sanitize_info makes the info json-serializable
1947 print(json.dumps(ydl.sanitize_info(info)))
1948 ```
1949 #### Download using an info-json
1951 ```python
1952 import yt_dlp
1954 INFO_FILE = 'path/to/video.info.json'

2109 # CHANGES FROM YOUTUBE-DL
2111 ### New features
2113 * Forked from [**yt-dlc@f9401f2**](https://github.com/blackjack4494/yt-dlc/commit/f9401f2a91987068139c5f757b12fc711d4c0cee) and merged with [**youtube-dl@be008e6**](https://github.com/ytdl-org/youtube-dl/commit/be008e657d79832642e2158557c899249c9e31cd) ([exceptions](https://github.com/yt-dlp/yt-dlp/issues/21))
2115 * **[SponsorBlock Integration](#sponsorblock-options)**: You can mark/remove sponsor sections in YouTube videos by utilizing the [SponsorBlock](https://sponsor.ajay.app) API
2117 * **[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))
2119 * **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.
2121 * **YouTube improvements**:
2122 * 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`)
2123 * Fix for [n-sig based throttling](https://github.com/ytdl-org/youtube-dl/issues/29326) **\***
2124 * Supports some (but not all) age-gated content without cookies
2125 * Download livestreams from the start using `--live-from-start` (*experimental*)
2126 * Channel URLs download all uploads of the channel, including shorts and live
2128 * **Cookies from browser**: Cookies can be automatically extracted from all major web browsers using `--cookies-from-browser BROWSER[+KEYRING][:PROFILE][::CONTAINER]`
2130 * **Download time range**: Videos can be downloaded partially based on either timestamps or chapters using `--download-sections`
2132 * **Split video by chapters**: Videos can be split into multiple files based on chapters using `--split-chapters`
2134 * **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
2136 * **Aria2c with HLS/DASH**: You can use `aria2c` as the external downloader for DASH(mpd) and HLS(m3u8) formats
2138 * **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)
2140 * **New MSOs**: Philo, Spectrum, SlingTV, Cablevision, RCN etc.
2142 * **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
2144 * **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`)
2146 * **Portable Configuration**: Configuration files are automatically loaded from the home and root directories. See [CONFIGURATION](#configuration) for details
2148 * **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`
2150 * **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-filter` etc
2152 * **Improvements**: Regex and other operators in `--format`/`--match-filter`, multiple `--postprocessor-args` and `--downloader-args`, faster archive checking, more [format selection options](#format-selection), merge multi-video/audio, multiple `--config-locations`, `--exec` at different stages, etc
2154 * **Plugins**: Extractors and PostProcessors can be loaded from an external file. See [plugins](#plugins) for details
2156 * **Self updater**: The releases can be updated using `yt-dlp -U`, and downgraded using `--update-to` if required
2158 * **Automated builds**: [Nightly/master builds](#update-channels) can be used with `--update-to nightly` and `--update-to master`
2160 See [changelog](Changelog.md) or [commits](https://github.com/yt-dlp/yt-dlp/commits) for the full list of changes
2162 Features marked with a **\*** have been back-ported to youtube-dl
2164 ### Differences in default behavior
2166 Some of yt-dlp's default options are different from that of youtube-dl and youtube-dlc:
2168 * yt-dlp supports only [Python 3.8+](## "Windows 7"), and *may* 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)
2169 * The options `--auto-number` (`-A`), `--title` (`-t`) and `--literal` (`-l`), no longer work. See [removed options](#Removed) for details
2170 * `avconv` is not supported as an alternative to `ffmpeg`
2171 * yt-dlp stores config files in slightly different locations to youtube-dl. See [CONFIGURATION](#configuration) for a list of correct locations
2172 * 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`
2173 * 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
2174 * 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
2175 * 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
2176 * `--no-abort-on-error` is enabled by default. Use `--abort-on-error` or `--compat-options abort-on-error` to abort on errors instead
2177 * 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
2178 * `--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
2179 * 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
2180 * `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
2181 * The output of `-F` is listed in a new format. Use `--compat-options list-formats` to revert this
2182 * 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
2183 * 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
2184 * Unavailable videos are also listed for YouTube playlists. Use `--compat-options no-youtube-unavailable-videos` to remove this
2185 * 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.
2186 * 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
2187 * Thumbnail embedding in `mp4` is done with mutagen if possible. Use `--compat-options embed-thumbnail-atomicparsley` to force the use of AtomicParsley instead
2188 * 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
2189 * 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
2190 * `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`
2191 * 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
2192 * ~~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~~
2193 * yt-dlp versions between 2021.09.01 and 2023.01.02 applies `--match-filter` 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
2194 * 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
2195 * 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.
2196 * The sub-modules `swfinterp`, `casefold` are removed.
2198 For ease of use, a few more compat options are available:
2200 * `--compat-options all`: Use all compat options (Do NOT use)
2201 * `--compat-options youtube-dl`: Same as `--compat-options all,-multistreams,-playlist-match-filter,-manifest-filesize-approx`
2202 * `--compat-options youtube-dlc`: Same as `--compat-options all,-no-live-chat,-no-youtube-channel-redirect,-playlist-match-filter,-manifest-filesize-approx`
2203 * `--compat-options 2021`: Same as `--compat-options 2022,no-certifi,filename-sanitization,no-youtube-prefer-utc-upload-date`
2204 * `--compat-options 2022`: Same as `--compat-options 2023,playlist-match-filter,no-external-downloader-progress,prefer-legacy-http-handler,manifest-filesize-approx`
2205 * `--compat-options 2023`: Currently does nothing. Use this to enable all future compat options
