77 # NEW FEATURES
78
79 * Forked from [**yt-dlc@f9401f2**](https://github.com/blackjack4494/yt-dlc/commit/f9401f2a91987068139c5f757b12fc711d4c0cee) and merged with [**youtube-dl@66ab08**](https://github.com/ytdl-org/youtube-dl/commit/66ab0814c4baa2dc79c2dd5287bc0ad61a37c5b9) ([exceptions](https://github.com/yt-dlp/yt-dlp/issues/21))
80
81 * **[SponsorBlock Integration](#sponsorblock-options)**: You can mark/remove sponsor sections in YouTube videos by utilizing the [SponsorBlock](https://sponsor.ajay.app) API
82
83 * **[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))
84
85 * **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.
86
87 * **YouTube improvements**:
88 * 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`)
89 * Fix for [n-sig based throttling](https://github.com/ytdl-org/youtube-dl/issues/29326) **\***
90 * Supports some (but not all) age-gated content without cookies
91 * Download livestreams from the start using `--live-from-start` (*experimental*)
92 * Channel URLs download all uploads of the channel, including shorts and live
93
94 * **Cookies from browser**: Cookies can be automatically extracted from all major web browsers using `--cookies-from-browser BROWSER[+KEYRING][:PROFILE][::CONTAINER]`
95
96 * **Download time range**: Videos can be downloaded partially based on either timestamps or chapters using `--download-sections`
97
98 * **Split video by chapters**: Videos can be split into multiple files based on chapters using `--split-chapters`
99
100 * **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
101
102 * **Aria2c with HLS/DASH**: You can use `aria2c` as the external downloader for DASH(mpd) and HLS(m3u8) formats
103
104 * **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)
105
106 * **New MSOs**: Philo, Spectrum, SlingTV, Cablevision, RCN etc.
107
108 * **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
109
110 * **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`)
111
112 * **Portable Configuration**: Configuration files are automatically loaded from the home and root directories. See [CONFIGURATION](#configuration) for details
113
114 * **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`
115
116 * **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
117
118 * **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
119
120 * **Plugins**: Extractors and PostProcessors can be loaded from an external file. See [plugins](#plugins) for details
121
122 * **Self updater**: The releases can be updated using `yt-dlp -U`, and downgraded using `--update-to` if required
123
124 * **Nightly builds**: [Automated nightly builds](#update-channels) can be used with `--update-to nightly`
125
126 See [changelog](Changelog.md) or [commits](https://github.com/yt-dlp/yt-dlp/commits) for the full list of changes
127
128 Features marked with a **\*** have been back-ported to youtube-dl
129
130 ### Differences in default behavior
131
132 Some of yt-dlp's default options are different from that of youtube-dl and youtube-dlc:
133
134 * yt-dlp supports only [Python 3.7+](## "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)
135 * The options `--auto-number` (`-A`), `--title` (`-t`) and `--literal` (`-l`), no longer work. See [removed options](#Removed) for details
136 * `avconv` is not supported as an alternative to `ffmpeg`
137 * yt-dlp stores config files in slightly different locations to youtube-dl. See [CONFIGURATION](#configuration) for a list of correct locations
138 * 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`
139 * 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
140 * 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
141 * 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
142 * `--no-abort-on-error` is enabled by default. Use `--abort-on-error` or `--compat-options abort-on-error` to abort on errors instead
143 * 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
144 * `--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
145 * 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
146 * `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
147 * The output of `-F` is listed in a new format. Use `--compat-options list-formats` to revert this
148 * 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
149 * 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
150 * Unavailable videos are also listed for YouTube playlists. Use `--compat-options no-youtube-unavailable-videos` to remove this
151 * 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.
152 * 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
153 * Thumbnail embedding in `mp4` is done with mutagen if possible. Use `--compat-options embed-thumbnail-atomicparsley` to force the use of AtomicParsley instead
154 * 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
155 * 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
156 * `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`
157 * 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
158 * 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
159 * 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
160 * 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
161 * 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.
162
163 For ease of use, a few more compat options are available:
164
165 * `--compat-options all`: Use all compat options (Do NOT use)
166 * `--compat-options youtube-dl`: Same as `--compat-options all,-multistreams,-playlist-match-filter`
167 * `--compat-options youtube-dlc`: Same as `--compat-options all,-no-live-chat,-no-youtube-channel-redirect,-playlist-match-filter`
168 * `--compat-options 2021`: Same as `--compat-options 2022,no-certifi,filename-sanitization,no-youtube-prefer-utc-upload-date`
169 * `--compat-options 2022`: Same as `--compat-options playlist-match-filter,no-external-downloader-progress,prefer-legacy-http-handler`. Use this to enable all future compat options

182 <!-- MANPAGE: END EXCLUDED SECTION -->
183
184 You can install yt-dlp using [the binaries](#release-files), [pip](https://pypi.org/project/yt-dlp) or one using a third-party package manager. See [the wiki](https://github.com/yt-dlp/yt-dlp/wiki/Installation) for detailed instructions
185
186
187 ## UPDATE
188 You can use `yt-dlp -U` to update if you are using the [release binaries](#release-files)
189
190 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
191
192 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
193
194 <a id="update-channels"/>
195
196 There are currently two release channels for binaries, `stable` and `nightly`.
197 `stable` is the default channel, and many of its changes have been tested by users of the nightly channel.
198 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](https://github.com/yt-dlp/yt-dlp-nightly-builds/releases).
199
200 When using `--update`/`-U`, a release binary will only update to its current channel.
201 `--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.
202
203 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.
204
205 Example usage:
206 * `yt-dlp --update-to nightly` change to `nightly` channel and update to its latest release
207 * `yt-dlp --update-to stable@2023.02.17` upgrade/downgrade to release to `stable` channel tag `2023.02.17`
208 * `yt-dlp --update-to 2023.01.06` upgrade/downgrade to tag `2023.01.06` if it exists on the current channel
209 * `yt-dlp --update-to example/yt-dlp@2023.03.01` upgrade/downgrade to the release from the `example/yt-dlp` repository, tag `2023.03.01`

257 ## DEPENDENCIES
258 Python versions 3.7+ (CPython and PyPy) are supported. Other versions and implementations may or may not work correctly.
259
260 <!-- Python 3.5+ uses VC++14 and it is already embedded in the binary created
261 <!x-- https://www.microsoft.com/en-us/download/details.aspx?id=26999 --x>
262 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.
263 -->
264
265 While all the other dependencies are optional, `ffmpeg` and `ffprobe` are highly recommended
266
267 ### Strongly recommended
268
269 * [**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)
270
271 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](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
272
273 **Important**: What you need is ffmpeg *binary*, **NOT** [the python package of the same name](https://pypi.org/project/ffmpeg)

300
301 To use or redistribute the dependencies, you must agree to their respective licensing terms.
302
303 The standalone release binaries are built with the Python interpreter and the packages marked with **\*** included.
304
305 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
306
307
308 ## COMPILE
309
310 ### Standalone PyInstaller Builds
311 To build the standalone executable, you must have Python and `pyinstaller` (plus any of yt-dlp's [optional dependencies](#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.
312
313 python3 -m pip install -U pyinstaller -r requirements.txt
314 python3 devscripts/make_lazy_extractors.py
315 python3 pyinst.py
316
317 On some systems, you may need to use `py` or `python` instead of `python3`.
318
319 `pyinst.py` 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).
320
321 **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.
322
323 **Important**: Running `pyinstaller` directly **without** using `pyinst.py` is **not** officially supported. This may or may not work correctly.
324
325 ### Platform-independent Binary (UNIX)
326 You will need the build tools `python` (3.7+), `zip`, `make` (GNU), `pandoc`\* and `pytest`\*.
327
328 After installing these, simply run `make`.
329
330 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)
331
332 ### Standalone Py2Exe Builds (Windows)
333
334 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.
335
336 If you wish to build it anyway, install Python and py2exe, and then simply run `setup.py py2exe`
337
338 py -m pip install -U py2exe -r requirements.txt
339 py devscripts/make_lazy_extractors.py
340 py setup.py py2exe
341
342 ### Related scripts
343
344 * **`devscripts/update-version.py`** - Update the version number based on current date.
345 * **`devscripts/set-variant.py`** - Set the build variant of the executable.
346 * **`devscripts/make_changelog.py`** - Create a markdown changelog using short commit messages and update `CONTRIBUTORS` file.
347 * **`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.
348
349 Note: See their `--help` for more info.
350
351 ### Forking the project
352 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.

354 # USAGE AND OPTIONS
355
356 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
357 yt-dlp [OPTIONS] [--] URL [URL...]
358
359 `Ctrl+F` is your friend :D
360 <!-- MANPAGE: END EXCLUDED SECTION -->
361
362 <!-- Auto generated -->
363 ## General Options:
364 -h, --help Print this help text and exit
365 --version Print program version and exit
366 -U, --update Update this program to the latest version
367 --no-update Do not check for updates (default)
368 --update-to [CHANNEL]@[TAG] Upgrade/downgrade to a specific version.
369 CHANNEL can be a repository as well. CHANNEL
370 and TAG default to "stable" and "latest"
371 respectively if omitted; See "UPDATE" for
372 details. Supported channels: stable, nightly
373 -i, --ignore-errors Ignore download and postprocessing errors.
374 The download will be considered successful
375 even if the postprocessing fails
376 --no-abort-on-error Continue with next video on download errors;
377 e.g. to skip unavailable videos in a
378 playlist (default)
379 --abort-on-error Abort downloading of further videos if an
380 error occurs (Alias: --no-ignore-errors)
381 --dump-user-agent Display the current user-agent and exit
382 --list-extractors List all supported extractors and exit
383 --extractor-descriptions Output descriptions of all supported
384 extractors and exit
385 --use-extractors NAMES Extractor names to use separated by commas.
386 You can also use regexes, "all", "default"
387 and "end" (end URL matching); e.g. --ies
388 "holodex.*,end,youtube". Prefix the name
389 with a "-" to exclude it, e.g. --ies
390 default,-generic. Use --list-extractors for
391 a list of extractor names. (Alias: --ies)
392 --default-search PREFIX Use this prefix for unqualified URLs. E.g.
393 "gvsearch2:python" downloads two videos from
394 google videos for the search term "python".
395 Use the value "auto" to let yt-dlp guess
396 ("auto_warning" to emit a warning when
397 guessing). "error" just throws an error. The
398 default value "fixup_error" repairs broken
399 URLs, but emits an error if this is not
400 possible instead of searching
401 --ignore-config Don't load any more configuration files
402 except those given by --config-locations.
403 For backward compatibility, if this option
404 is found inside the system configuration
405 file, the user configuration is not loaded.
406 (Alias: --no-config)
407 --no-config-locations Do not load any custom configuration files
408 (default). When given inside a configuration
409 file, ignore all previous --config-locations
410 defined in the current file
411 --config-locations PATH Location of the main configuration file;
412 either the path to the config or its
413 containing directory ("-" for stdin). Can be
414 used multiple times and inside other
415 configuration files
416 --flat-playlist Do not extract the videos of a playlist,
417 only list them
418 --no-flat-playlist Fully extract the videos of a playlist
419 (default)
420 --live-from-start Download livestreams from the start.
421 Currently only supported for YouTube
422 (Experimental)
423 --no-live-from-start Download livestreams from the current time
424 (default)
425 --wait-for-video MIN[-MAX] Wait for scheduled streams to become
426 available. Pass the minimum number of
427 seconds (or range) to wait between retries
428 --no-wait-for-video Do not wait for scheduled streams (default)
429 --mark-watched Mark videos watched (even with --simulate)
430 --no-mark-watched Do not mark videos watched (default)
431 --color [STREAM:]POLICY Whether to emit color codes in output,
432 optionally prefixed by the STREAM (stdout or
433 stderr) to apply the setting to. Can be one
434 of "always", "auto" (default), "never", or
435 "no_color" (use non color terminal
436 sequences). Can be used multiple times
437 --compat-options OPTS Options that can help keep compatibility
438 with youtube-dl or youtube-dlc
439 configurations by reverting some of the
440 changes made in yt-dlp. See "Differences in
441 default behavior" for details
442 --alias ALIASES OPTIONS Create aliases for an option string. Unless
443 an alias starts with a dash "-", it is
444 prefixed with "--". Arguments are parsed
445 according to the Python string formatting
446 mini-language. E.g. --alias get-audio,-X
447 "-S=aext:{0},abr -x --audio-format {0}"
448 creates options "--get-audio" and "-X" that
449 takes an argument (ARG0) and expands to
450 "-S=aext:ARG0,abr -x --audio-format ARG0".
451 All defined aliases are listed in the --help
452 output. Alias options can trigger more
453 aliases; so be careful to avoid defining
454 recursive options. As a safety measure, each
455 alias may be triggered a maximum of 100
456 times. This option can be used multiple times
457
458 ## Network Options:
459 --proxy URL Use the specified HTTP/HTTPS/SOCKS proxy. To
460 enable SOCKS proxy, specify a proper scheme,
461 e.g. socks5://user:pass@127.0.0.1:1080/.
462 Pass in an empty string (--proxy "") for
463 direct connection
464 --socket-timeout SECONDS Time to wait before giving up, in seconds
465 --source-address IP Client-side IP address to bind to
466 -4, --force-ipv4 Make all connections via IPv4
467 -6, --force-ipv6 Make all connections via IPv6
468 --enable-file-urls Enable file:// URLs. This is disabled by
469 default for security reasons.
470
471 ## Geo-restriction:
472 --geo-verification-proxy URL Use this proxy to verify the IP address for
473 some geo-restricted sites. The default proxy
474 specified by --proxy (or none, if the option
475 is not present) is used for the actual
476 downloading
477 --xff VALUE How to fake X-Forwarded-For HTTP header to
478 try bypassing geographic restriction. One of
479 "default" (only when known to be useful),
480 "never", an IP block in CIDR notation, or a
481 two-letter ISO 3166-2 country code
482
483 ## Video Selection:
484 -I, --playlist-items ITEM_SPEC Comma separated playlist_index of the items
485 to download. You can specify a range using
486 "[START]:[STOP][:STEP]". For backward
487 compatibility, START-STOP is also supported.
488 Use negative indices to count from the right
489 and negative STEP to download in reverse
490 order. E.g. "-I 1:3,7,-5::2" used on a
491 playlist of size 15 will download the items
492 at index 1,2,3,7,11,13,15
493 --min-filesize SIZE Abort download if filesize is smaller than
494 SIZE, e.g. 50k or 44.6M
495 --max-filesize SIZE Abort download if filesize is larger than
496 SIZE, e.g. 50k or 44.6M
497 --date DATE Download only videos uploaded on this date.
498 The date can be "YYYYMMDD" or in the format
499 [now|today|yesterday][-N[day|week|month|year]].
500 E.g. "--date today-2weeks" downloads only
501 videos uploaded on the same day two weeks ago
502 --datebefore DATE Download only videos uploaded on or before
503 this date. The date formats accepted is the
504 same as --date
505 --dateafter DATE Download only videos uploaded on or after
506 this date. The date formats accepted is the
507 same as --date
508 --match-filters FILTER Generic video filter. Any "OUTPUT TEMPLATE"
509 field can be compared with a number or a
510 string using the operators defined in
511 "Filtering Formats". You can also simply
512 specify a field to match if the field is
513 present, use "!field" to check if the field
514 is not present, and "&" to check multiple
515 conditions. Use a "\" to escape "&" or
516 quotes if needed. If used multiple times,
517 the filter matches if atleast one of the
518 conditions are met. E.g. --match-filter
519 !is_live --match-filter "like_count>?100 &
520 description~='(?i)\bcats \& dogs\b'" matches
521 only videos that are not live OR those that
522 have a like count more than 100 (or the like
523 field is not available) and also has a
524 description that contains the phrase "cats &
525 dogs" (caseless). Use "--match-filter -" to
526 interactively ask whether to download each
527 video
528 --no-match-filters Do not use any --match-filter (default)
529 --break-match-filters FILTER Same as "--match-filters" but stops the
530 download process when a video is rejected
531 --no-break-match-filters Do not use any --break-match-filters (default)
532 --no-playlist Download only the video, if the URL refers
533 to a video and a playlist
534 --yes-playlist Download the playlist, if the URL refers to
535 a video and a playlist
536 --age-limit YEARS Download only videos suitable for the given
537 age
538 --download-archive FILE Download only videos not listed in the
539 archive file. Record the IDs of all
540 downloaded videos in it
541 --no-download-archive Do not use archive file (default)
542 --max-downloads NUMBER Abort after downloading NUMBER files
543 --break-on-existing Stop the download process when encountering
544 a file that is in the archive
545 --break-per-input Alters --max-downloads, --break-on-existing,
546 --break-match-filter, and autonumber to
547 reset per input URL
548 --no-break-per-input --break-on-existing and similar options
549 terminates the entire download queue
550 --skip-playlist-after-errors N Number of allowed failures until the rest of
551 the playlist is skipped
552
553 ## Download Options:
554 -N, --concurrent-fragments N Number of fragments of a dash/hlsnative
555 video that should be downloaded concurrently
556 (default is 1)
557 -r, --limit-rate RATE Maximum download rate in bytes per second,
558 e.g. 50K or 4.2M
559 --throttled-rate RATE Minimum download rate in bytes per second
560 below which throttling is assumed and the
561 video data is re-extracted, e.g. 100K
562 -R, --retries RETRIES Number of retries (default is 10), or
563 "infinite"
564 --file-access-retries RETRIES Number of times to retry on file access
565 error (default is 3), or "infinite"
566 --fragment-retries RETRIES Number of retries for a fragment (default is
567 10), or "infinite" (DASH, hlsnative and ISM)
568 --retry-sleep [TYPE:]EXPR Time to sleep between retries in seconds
569 (optionally) prefixed by the type of retry
570 (http (default), fragment, file_access,
571 extractor) to apply the sleep to. EXPR can
572 be a number, linear=START[:END[:STEP=1]] or
573 exp=START[:END[:BASE=2]]. This option can be
574 used multiple times to set the sleep for the
575 different retry types, e.g. --retry-sleep
576 linear=1::2 --retry-sleep fragment:exp=1:20
577 --skip-unavailable-fragments Skip unavailable fragments for DASH,
578 hlsnative and ISM downloads (default)
579 (Alias: --no-abort-on-unavailable-fragments)
580 --abort-on-unavailable-fragments
581 Abort download if a fragment is unavailable
582 (Alias: --no-skip-unavailable-fragments)
583 --keep-fragments Keep downloaded fragments on disk after
584 downloading is finished
585 --no-keep-fragments Delete downloaded fragments after
586 downloading is finished (default)

596 bandwidth throttling imposed by a webserver
597 (experimental)
598 --playlist-random Download playlist videos in random order
599 --lazy-playlist Process entries in the playlist as they are
600 received. This disables n_entries,
601 --playlist-random and --playlist-reverse
602 --no-lazy-playlist Process videos in the playlist only after
603 the entire playlist is parsed (default)
604 --xattr-set-filesize Set file xattribute ytdl.filesize with
605 expected file size
606 --hls-use-mpegts Use the mpegts container for HLS videos;
607 allowing some players to play the video
608 while downloading, and reducing the chance
609 of file corruption if download is
610 interrupted. This is enabled by default for
611 live streams
612 --no-hls-use-mpegts Do not use the mpegts container for HLS
613 videos. This is default when not downloading
614 live streams
615 --download-sections REGEX Download only chapters that match the
616 regular expression. A "*" prefix denotes
617 time-range instead of chapter. Negative
618 timestamps are calculated from the end.
619 "*from-url" can be used to download between
620 the "start_time" and "end_time" extracted
621 from the URL. Needs ffmpeg. This option can
622 be used multiple times to download multiple
623 sections, e.g. --download-sections
624 "*10:15-inf" --download-sections "intro"
625 --downloader [PROTO:]NAME Name or path of the external downloader to
626 use (optionally) prefixed by the protocols
627 (http, ftp, m3u8, dash, rstp, rtmp, mms) to
628 use it for. Currently supports native,
629 aria2c, avconv, axel, curl, ffmpeg, httpie,
630 wget. You can use this option multiple times
631 to set different downloaders for different
632 protocols. E.g. --downloader aria2c
633 --downloader "dash,m3u8:native" will use
634 aria2c for http/ftp downloads, and the

1151 # CONFIGURATION
1152
1153 You can configure yt-dlp by placing any supported command line option to a configuration file. The configuration is loaded from the following locations:
1154
1155 1. **Main Configuration**:
1156 * The file given by `--config-location`
1157 1. **Portable Configuration**: (Recommended for portable installations)
1158 * If using a binary, `yt-dlp.conf` in the same directory as the binary
1159 * If running from source-code, `yt-dlp.conf` in the parent directory of `yt_dlp`
1160 1. **Home Configuration**:
1161 * `yt-dlp.conf` in the home path given by `-P`
1162 * If `-P` is not given, the current directory is searched
1163 1. **User Configuration**:
1164 * `${XDG_CONFIG_HOME}/yt-dlp.conf`
1165 * `${XDG_CONFIG_HOME}/yt-dlp/config` (recommended on Linux/macOS)
1166 * `${XDG_CONFIG_HOME}/yt-dlp/config.txt`
1167 * `${APPDATA}/yt-dlp.conf`
1168 * `${APPDATA}/yt-dlp/config` (recommended on Windows)
1169 * `${APPDATA}/yt-dlp/config.txt`
1170 * `~/yt-dlp.conf`
1171 * `~/yt-dlp.conf.txt`
1172 * `~/.yt-dlp/config`
1173 * `~/.yt-dlp/config.txt`
1174
1175 See also: [Notes about environment variables](#notes-about-environment-variables)
1176 1. **System Configuration**:
1177 * `/etc/yt-dlp.conf`
1178 * `/etc/yt-dlp/config`
1179 * `/etc/yt-dlp/config.txt`
1180
1181 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:
1182 ```
1183 # Lines starting with # are comments
1184
1185 # Always extract audio
1186 -x
1187
1188 # Do not copy the mtime
1189 --no-mtime
1190
1191 # Use this proxy
1192 --proxy 127.0.0.1:3128
1193
1194 # Save all videos under YouTube directory in your home directory
1195 -o ~/YouTube/%(title)s.%(ext)s
1196 ```
1197
1198 **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.
1199
1200 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.
1201
1202 ### Configuration file encoding
1203
1204 The configuration files are decoded according to the UTF BOM if present, and in the encoding from system locale otherwise.
1205
1206 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.
1207
1208 ### Authentication with netrc
1209
1210 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:
1211 ```
1212 touch ${HOME}/.netrc
1213 chmod a-rwx,u+rw ${HOME}/.netrc
1214 ```
1215 After that you can add credentials for an extractor in the following format, where *extractor* is the name of the extractor in lowercase:
1216 ```
1217 machine <extractor> login <username> password <password>
1218 ```
1219 E.g.
1220 ```
1221 machine youtube login myaccount@gmail.com password my_youtube_password
1222 machine twitch login my_twitch_account_name password my_twitch_password
1223 ```
1224 To activate authentication with the `.netrc` file you should pass `--netrc` to yt-dlp or place it in the [configuration file](#configuration).
1225
1226 The default location of the .netrc file is `~` (see below).
1227
1228 As an alternative to using the `.netrc` file, which has the disadvantage of keeping your passwords in a plain text file, you can configure a custom shell command to provide the credentials for an extractor. This is done by providing the `--netrc-cmd` parameter, it shall output the credentials in the netrc format and return `0` on success, other values will be treated as an error. `{}` in the command will be replaced by the name of the extractor to make it possible to select the credentials for the right extractor.
1229
1230 E.g. To use an encrypted `.netrc` file stored as `.authinfo.gpg`
1231 ```
1232 yt-dlp --netrc-cmd 'gpg --decrypt ~/.authinfo.gpg' https://www.youtube.com/watch?v=BaW_jenozKc
1233 ```
1234
1235
1236 ### Notes about environment variables
1237 * Environment variables are normally specified as `${VARIABLE}`/`$VARIABLE` on UNIX and `%VARIABLE%` on Windows; but is always shown as `${VARIABLE}` in this documentation
1238 * yt-dlp also allow using UNIX-style variables on Windows for path-like options; e.g. `--output`, `--config-location`
1239 * If unset, `${XDG_CONFIG_HOME}` defaults to `~/.config` and `${XDG_CACHE_HOME}` to `~/.cache`
1240 * On Windows, `~` points to `${HOME}` if present; or, `${USERPROFILE}` or `${HOMEDRIVE}${HOMEPATH}` otherwise
1241 * On Windows, `${USERPROFILE}` generally points to `C:\Users\<user name>` and `${APPDATA}` to `${USERPROFILE}\AppData\Roaming`
1242
1243 # OUTPUT TEMPLATE
1244
1245 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.
1246
1247 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
1248 **tl;dr:** [navigate me to examples](#output-template-examples).
1249 <!-- MANPAGE: END EXCLUDED SECTION -->
1250
1251 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).
1252
1253 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.
1254
1255 The field names themselves (the part inside the parenthesis) can also have some special formatting:
1256
1257 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
1258
1259 1. **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`
1260
1261 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`
1262
1263 1. **Alternatives**: Alternate fields can be specified separated with a `,`. E.g. `%(release_date>%Y,upload_date>%Y|Unknown)s`
1264
1265 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`
1266
1267 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`
1268
1269 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)
1270
1271 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
1272
1273 To summarize, the general syntax for a field is:
1274 ```
1275 %(name[.keys][addition][>strf][,alternate][&replacement][|default])[flags][width][.precision][length]type
1276 ```
1277
1278 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.
1279
1280 <a id="outtmpl-postprocess-note"/>
1281
1282 **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.

1404
1405 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.
1406
1407 **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).
1408
1409 **Tip**: Look at the `-j` output to identify which fields are available for the particular URL
1410
1411 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`.
1412
1413 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.
1414
1415 To use percent literals in an output template use `%%`. To output to stdout use `-o -`.
1416
1417 The current default template is `%(title)s [%(id)s].%(ext)s`.
1418
1419 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.
1420

1462 # FORMAT SELECTION
1463
1464 By default, yt-dlp tries to download the best available quality if you **don't** pass any options.
1465 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`.
1466
1467 **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.
1468
1469 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.
1470
1471 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
1472 **tl;dr:** [navigate me to examples](#format-selection-examples).
1473 <!-- MANPAGE: END EXCLUDED SECTION -->
1474
1475 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.
1476
1477 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.
1478
1479 You can use `-f -` to interactively provide the format selector *for each video*
1480
1481 You can also use special names to select particular edge case formats:
1482
1483 - `all`: Select **all formats** separately
1484 - `mergeall`: Select and **merge all formats** (Must be used with `--audio-multistreams`, `--video-multistreams` or both)
1485 - `b*`, `best*`: Select the best quality format that **contains either** a video or an audio or both (ie; `vcodec!=none or acodec!=none`)
1486 - `b`, `best`: Select the best quality format that **contains both** video and audio. Equivalent to `best*[vcodec!=none][acodec!=none]`
1487 - `bv`, `bestvideo`: Select the best quality **video-only** format. Equivalent to `best*[acodec=none]`
1488 - `bv*`, `bestvideo*`: Select the best quality format that **contains video**. It may also contain audio. Equivalent to `best*[vcodec!=none]`
1489 - `ba`, `bestaudio`: Select the best quality **audio-only** format. Equivalent to `best*[vcodec=none]`
1490 - `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))
1491 - `w*`, `worst*`: Select the worst quality format that contains either a video or an audio
1492 - `w`, `worst`: Select the worst quality format that contains both video and audio. Equivalent to `worst*[vcodec!=none][acodec!=none]`
1493 - `wv`, `worstvideo`: Select the worst quality video-only format. Equivalent to `worst*[acodec=none]`
1494 - `wv*`, `worstvideo*`: Select the worst quality format that contains video. It may also contain audio. Equivalent to `worst*[vcodec!=none]`
1495 - `wa`, `worstaudio`: Select the worst quality audio-only format. Equivalent to `worst*[vcodec=none]`
1496 - `wa*`, `worstaudio*`: Select the worst quality format that contains audio. It may also contain video. Equivalent to `worst*[acodec!=none]`
1497
1498 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.
1499
1500 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.
1501
1502 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.
1503
1504 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`.
1505
1506 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.
1507
1508 **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
1509
1510 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`.
1511
1512 ## Filtering Formats
1513
1514 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`).
1515
1516 The following numeric meta fields can be used with comparisons `<`, `<=`, `>`, `>=`, `=` (equals), `!=` (not equals):
1517
1518 - `filesize`: The number of bytes, if known in advance
1519 - `filesize_approx`: An estimate for the number of bytes
1520 - `width`: Width of the video, if known
1521 - `height`: Height of the video, if known
1522 - `aspect_ratio`: Aspect ratio of the video, if known
1523 - `tbr`: Average bitrate of audio and video in KBit/s
1524 - `abr`: Average audio bitrate in KBit/s
1525 - `vbr`: Average video bitrate in KBit/s
1526 - `asr`: Audio sampling rate in Hertz
1527 - `fps`: Frame rate
1528 - `audio_channels`: The number of audio channels
1529 - `stretched_ratio`: `width:height` of the video's pixels, if not square
1530
1531 Also filtering work for comparisons `=` (equals), `^=` (starts with), `$=` (ends with), `*=` (contains), `~=` (matches regex) and following string meta fields:
1532
1533 - `url`: Video URL
1534 - `ext`: File extension
1535 - `acodec`: Name of the audio codec in use
1536 - `vcodec`: Name of the video codec in use
1537 - `container`: Name of the container format
1538 - `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`)
1539 - `language`: Language code
1540 - `dynamic_range`: The dynamic range of the video
1541 - `format_id`: A short description of the format
1542 - `format`: A human-readable description of the format
1543 - `format_note`: Additional info about the format
1544 - `resolution`: Textual description of width and height
1545
1546 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 `._-`.
1547
1548 **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.
1549
1550 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.
1551
1552 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.
1553
1554 ## Sorting Formats
1555
1556 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...`.
1557
1558 The available fields are:
1559
1560 - `hasvid`: Gives priority to formats that have a video stream
1561 - `hasaud`: Gives priority to formats that have an audio stream
1562 - `ie_pref`: The format preference
1563 - `lang`: The language preference
1564 - `quality`: The quality of the format
1565 - `source`: The preference of the source
1566 - `proto`: Protocol used for download (`https`/`ftps` > `http`/`ftp` > `m3u8_native`/`m3u8` > `http_dash_segments`> `websocket_frag` > `mms`/`rtsp` > `f4f`/`f4m`)
1567 - `vcodec`: Video Codec (`av01` > `vp9.2` > `vp9` > `h265` > `h264` > `vp8` > `h263` > `theora` > other)
1568 - `acodec`: Audio Codec (`flac`/`alac` > `wav`/`aiff` > `opus` > `vorbis` > `aac` > `mp4a` > `mp3` > `ac4` > `eac3` > `ac3` > `dts` > other)
1569 - `codec`: Equivalent to `vcodec,acodec`
1570 - `vext`: Video Extension (`mp4` > `mov` > `webm` > `flv` > other). If `--prefer-free-formats` is used, `webm` is preferred.
1571 - `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`
1572 - `ext`: Equivalent to `vext,aext`
1573 - `filesize`: Exact filesize, if known in advance
1574 - `fs_approx`: Approximate filesize
1575 - `size`: Exact filesize if available, otherwise approximate filesize
1576 - `height`: Height of video
1577 - `width`: Width of video
1578 - `res`: Video resolution, calculated as the smallest dimension.
1579 - `fps`: Framerate of video
1580 - `hdr`: The dynamic range of the video (`DV` > `HDR12` > `HDR10+` > `HDR10` > `HLG` > `SDR`)
1581 - `channels`: The number of audio channels
1582 - `tbr`: Total average bitrate in KBit/s
1583 - `vbr`: Average video bitrate in KBit/s
1584 - `abr`: Average audio bitrate in KBit/s
1585 - `br`: Average bitrate in KBit/s, `tbr`/`vbr`/`abr`
1586 - `asr`: Audio sample rate in Hz
1587
1588 **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.
1589
1590 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.
1591
1592 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.
1593
1594 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.
1595
1596 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`.
1597
1598 **Tip**: You can use the `-v -F` to see how the formats have been sorted (worst to best).

1722
1723 # MODIFYING METADATA
1724
1725 The metadata obtained by the extractors can be modified by using `--parse-metadata` and `--replace-in-metadata`
1726
1727 `--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.
1728
1729 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.
1730
1731 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`.
1732
1733 This option also has a few special uses:
1734
1735 * 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
1736
1737 * 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.
1738
1739 **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.
1740
1741 For reference, these are the fields yt-dlp adds by default to the file metadata:
1742
1743 Metadata fields | From
1744 :--------------------------|:------------------------------------------------
1745 `title` | `track` or `title`
1746 `date` | `upload_date`
1747 `description`, `synopsis` | `description`
1748 `purl`, `comment` | `webpage_url`
1749 `track` | `track_number`
1750 `artist` | `artist`, `creator`, `uploader` or `uploader_id`
1751 `genre` | `genre`
1752 `album` | `album`
1753 `album_artist` | `album_artist`
1754 `disc` | `disc_number`
1755 `show` | `series`
1756 `season_number` | `season_number`
1757 `episode_id` | `episode` or `episode_id`
1758 `episode_sort` | `episode_number`
1759 `language` of each stream | the format's `language`
1760
1761 **Note**: The file format may not support some of these fields

1766 ```bash
1767 # Interpret the title as "Artist - Title"
1768 $ yt-dlp --parse-metadata "title:%(artist)s - %(title)s"
1769
1770 # Regex example
1771 $ yt-dlp --parse-metadata "description:Artist - (?P<artist>.+)"
1772
1773 # Set title as "Series name S01E05"
1774 $ yt-dlp --parse-metadata "%(series)s S%(season_number)02dE%(episode_number)02d:%(title)s"
1775
1776 # Prioritize uploader as the "artist" field in video metadata
1777 $ yt-dlp --parse-metadata "%(uploader|)s:%(meta_artist)s" --embed-metadata
1778
1779 # Set "comment" field in video metadata using description instead of webpage_url,
1780 # handling multiple lines correctly
1781 $ yt-dlp --parse-metadata "description:(?s)(?P<meta_comment>.+)" --embed-metadata
1782
1783 # Do not set any "synopsis" in the video metadata
1784 $ yt-dlp --parse-metadata ":(?P<meta_synopsis>)"
1785
1786 # Remove "formats" field from the infojson by setting it to an empty string
1787 $ yt-dlp --parse-metadata "video::(?P<formats>)" --write-info-json
1788
1789 # Replace all spaces and "_" in title and uploader with a `-`
1790 $ yt-dlp --replace-in-metadata "title,uploader" "[ _]" "-"
1791
1792 ```
1793
1794 # EXTRACTOR ARGUMENTS
1795
1796 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"`
1797
1798 Note: In CLI, `ARG` can use `-` instead of `_`; e.g. `youtube:player-client"` becomes `youtube:player_client"`
1799
1800 The following extractors use this feature:
1801
1802 #### youtube
1803 * `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
1804 * `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
1805 * `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.
1806 * `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
1807 * `player_params`: YouTube player parameters to use for player requests. Will overwrite any default ones set by yt-dlp.
1808 * `comment_sort`: `top` or `new` (default) - choose comment sorting mode (on YouTube's side)
1809 * `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`
1810 * 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
1811 * `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)
1812 * `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
1813 * `innertube_key`: Innertube API key to use for all API requests
1814 * `raise_incomplete_data`: `Incomplete Data Received` raises an error instead of reporting a warning
1815
1816 #### youtubetab (YouTube playlists, channels, feeds, etc.)
1817 * `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)
1818 * `approximate_date`: Extract approximate `upload_date` and `timestamp` in flat-playlist. This may cause date-based filters to be slightly off
1819
1820 #### generic
1821 * `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
1822 * `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`
1823 * `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
1824 * `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`
1825
1826 #### funimation
1827 * `language`: Audio languages to extract, e.g. `funimation:language=english,japanese`
1828 * `version`: The video version to extract - `uncut` or `simulcast`
1829
1830 #### crunchyrollbeta (Crunchyroll)
1831 * `format`: Which stream type(s) to extract (default: `adaptive_hls`). Potentially useful values include `adaptive_hls`, `adaptive_dash`, `vo_adaptive_hls`, `vo_adaptive_dash`, `download_hls`, `download_dash`, `multitrack_adaptive_hls_v2`
1832 * `hardsub`: Preference order for which hardsub versions to extract, or `all` (default: `None` = no hardsubs), e.g. `crunchyrollbeta:hardsub=en-US,None`
1833
1834 #### vikichannel
1835 * `video_types`: Types of videos to download - one or more of `episodes`, `movies`, `clips`, `trailers`
1836
1837 #### niconico
1838 * `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.**
1839
1840 #### youtubewebarchive
1841 * `check_all`: Try to check more at the cost of more requests. One or more of `thumbnails`, `captures`
1842
1843 #### gamejolt
1844 * `comment_sort`: `hot` (default), `you` (cookies needed), `top`, `new` - choose comment sorting mode (on GameJolt's side)
1845
1846 #### hotstar
1847 * `res`: resolution to ignore - one or more of `sd`, `hd`, `fhd`
1848 * `vcodec`: vcodec to ignore - one or more of `h264`, `h265`, `dvh265`
1849 * `dr`: dynamic range to ignore - one or more of `sdr`, `hdr10`, `dv`

1855 * `api_hostname`: Hostname to use for mobile API requests, e.g. `api-h2.tiktokv.com`
1856 * `app_version`: App version to call mobile APIs with - should be set along with `manifest_app_version`, e.g. `20.2.1`
1857 * `manifest_app_version`: Numeric app version to call mobile APIs with, e.g. `221`
1858
1859 #### rokfinchannel

1861
1862 #### twitter
1863 * `api`: Select one of `graphql` (default), `legacy` or `syndication` as the API for tweet extraction. Has no effect if logged in
1864
1865 #### stacommu, wrestleuniverse
1866 * `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
1867
1868 #### twitch
1869 * `client_id`: Client ID value to be sent with GraphQL requests, e.g. `twitch:client_id=kimne78kx3ncx6brgo4mv6wki5h1ko`

1882 # PLUGINS
1883
1884 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!**
1885
1886 Plugins can be of `<type>`s `extractor` or `postprocessor`.
1887 - Extractor plugins do not need to be enabled from the CLI and are automatically invoked when the input URL is suitable for it.
1888 - Extractor plugins take priority over builtin extractors.
1889 - Postprocessor plugins can be invoked using `--use-postprocessor NAME`.
1890
1891
1892 Plugins are loaded from the namespace packages `yt_dlp_plugins.extractor` and `yt_dlp_plugins.postprocessor`.
1893
1894 In other words, the file structure on the disk looks something like:
1895
1896 yt_dlp_plugins/
1897 extractor/
1898 myplugin.py
1899 postprocessor/
1900 myplugin.py
1901
1902 yt-dlp looks for these `yt_dlp_plugins` namespace folders in many locations (see below) and loads in plugins from **all** of them.
1903
1904 See the [wiki for some known plugins](https://github.com/yt-dlp/yt-dlp/wiki/Plugins)
1905
1906 ## Installing Plugins
1907
1908 Plugins can be installed using various methods and locations.
1909
1910 1. **Configuration directories**:
1911 Plugin packages (containing a `yt_dlp_plugins` namespace folder) can be dropped into the following standard [configuration locations](#configuration):
1912 * **User Plugins**
1913 * `${XDG_CONFIG_HOME}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Linux/macOS)
1914 * `${XDG_CONFIG_HOME}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1915 * `${APPDATA}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Windows)
1916 * `${APPDATA}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1917 * `~/.yt-dlp/plugins/<package name>/yt_dlp_plugins/`
1918 * `~/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1919 * **System Plugins**
1920 * `/etc/yt-dlp/plugins/<package name>/yt_dlp_plugins/`
1921 * `/etc/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1922 2. **Executable location**: Plugin packages can similarly be installed in a `yt-dlp-plugins` directory under the executable location (recommended for portable installations):
1923 * Binary: where `<root-dir>/yt-dlp.exe`, `<root-dir>/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1924 * Source: where `<root-dir>/yt_dlp/__main__.py`, `<root-dir>/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1925
1926 3. **pip and other locations in `PYTHONPATH`**
1927 * 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.
1928 * Note: plugin files between plugin packages installed with pip must have unique filenames.
1929 * Any path in `PYTHONPATH` is searched in for the `yt_dlp_plugins` namespace folder.
1930 * Note: This does not apply for Pyinstaller/py2exe builds.
1931
1932
1933 `.zip`, `.egg` and `.whl` archives containing a `yt_dlp_plugins` namespace folder in their root are also supported as plugin packages.
1934 * e.g. `${XDG_CONFIG_HOME}/yt-dlp/plugins/mypluginpkg.zip` where `mypluginpkg.zip` contains `yt_dlp_plugins/<type>/myplugin.py`
1935
1936 Run yt-dlp with `--verbose` to check if the plugin has been loaded.
1937
1938 ## Developing Plugins
1939
1940 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.
1941
1942 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`).
1943
1944 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.
1945
1946 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.
1947
1948 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.
1949
1950 # EMBEDDING YT-DLP
1951
1952 yt-dlp makes the best effort to be a good command-line program, and thus should be callable from any programming language.
1953
1954 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.
1955
1956 From a Python program, you can embed yt-dlp in a more powerful fashion, like this:
1957
1958 ```python
1959 from yt_dlp import YoutubeDL
1960
1961 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
1962 with YoutubeDL() as ydl:
1963 ydl.download(URLS)
1964 ```
1965
1966 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.
1967
1968 **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)
1969
1970 ## Embedding examples
1971
1972 #### Extracting information
1973
1974 ```python
1975 import json
1976 import yt_dlp
1977
1978 URL = 'https://www.youtube.com/watch?v=BaW_jenozKc'
1979
1980 # ℹ️ See help(yt_dlp.YoutubeDL) for a list of available options and public functions
1981 ydl_opts = {}
1982 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
1983 info = ydl.extract_info(URL, download=False)
1984
1985 # ℹ️ ydl.sanitize_info makes the info json-serializable
1986 print(json.dumps(ydl.sanitize_info(info)))
1987 ```
1988 #### Download using an info-json
1989
1990 ```python
1991 import yt_dlp
1992
1993 INFO_FILE = 'path/to/video.info.json'
1994
1995 with yt_dlp.YoutubeDL() as ydl:
1996 error_code = ydl.download_with_info_file(INFO_FILE)
1997
1998 print('Some videos failed to download' if error_code
1999 else 'All videos successfully downloaded')
2000 ```
2001
2002 #### Extract audio
2003
2004 ```python
2005 import yt_dlp
2006
2007 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
2008
2009 ydl_opts = {
2010 'format': 'm4a/bestaudio/best',
2011 # ℹ️ See help(yt_dlp.postprocessor) for a list of available Postprocessors and their arguments
2012 'postprocessors': [{ # Extract audio using ffmpeg
2013 'key': 'FFmpegExtractAudio',
2014 'preferredcodec': 'm4a',
2015 }]
2016 }
2017
2018 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
2019 error_code = ydl.download(URLS)
2020 ```
2021
2022 #### Filter videos
2023
2024 ```python
2025 import yt_dlp
2026
2027 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
2028
2029 def longer_than_a_minute(info, *, incomplete):
2030 """Download only videos longer than a minute (or with unknown duration)"""
2031 duration = info.get('duration')
2032 if duration and duration < 60:
2033 return 'The video is too short'
2034
2035 ydl_opts = {
2036 'match_filter': longer_than_a_minute,
2037 }
2038
2039 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
2040 error_code = ydl.download(URLS)
2041 ```
2042
2043 #### Adding logger and progress hook
2044
2045 ```python
2046 import yt_dlp
2047
2048 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
2049
2050 class MyLogger:
2051 def debug(self, msg):
2052 # For compatibility with youtube-dl, both debug and info are passed into debug
2053 # You can distinguish them by the prefix '[debug] '
2054 if msg.startswith('[debug] '):
2055 pass
2056 else:
2057 self.info(msg)
2058
2059 def info(self, msg):
2060 pass
2061
2062 def warning(self, msg):
2063 pass
2064
2065 def error(self, msg):
2066 print(msg)
2067
2068
2069 # ℹ️ See "progress_hooks" in help(yt_dlp.YoutubeDL)
2070 def my_hook(d):
2071 if d['status'] == 'finished':
2072 print('Done downloading, now post-processing ...')
2073
2074
2075 ydl_opts = {
2076 'logger': MyLogger(),
2077 'progress_hooks': [my_hook],
2078 }
2079
2080 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
2081 ydl.download(URLS)
2082 ```
2083
2084 #### Add a custom PostProcessor
2085
2086 ```python
2087 import yt_dlp
2088
2089 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
2090
2091 # ℹ️ See help(yt_dlp.postprocessor.PostProcessor)
2092 class MyCustomPP(yt_dlp.postprocessor.PostProcessor):
2093 def run(self, info):
2094 self.to_screen('Doing stuff')
2095 return [], info
2096
2097
2098 with yt_dlp.YoutubeDL() as ydl:
2099 # ℹ️ "when" can take any value in yt_dlp.utils.POSTPROCESS_WHEN
2100 ydl.add_post_processor(MyCustomPP(), when='pre_process')
2101 ydl.download(URLS)
2102 ```
2103
2104
2105 #### Use a custom format selector
2106
2107 ```python
2108 import yt_dlp
2109
2110 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
2111
2112 def format_selector(ctx):
2113 """ Select the best video and the best audio that won't result in an mkv.
2114 NOTE: This is just an example and does not handle all cases """
2115
2116 # formats are already sorted worst to best
2117 formats = ctx.get('formats')[::-1]
2118
2119 # acodec='none' means there is no audio
2120 best_video = next(f for f in formats
2121 if f['vcodec'] != 'none' and f['acodec'] == 'none')
2122
2123 # find compatible audio extension
2124 audio_ext = {'mp4': 'm4a', 'webm': 'webm'}[best_video['ext']]
2125 # vcodec='none' means there is no video
2126 best_audio = next(f for f in formats if (
2127 f['acodec'] != 'none' and f['vcodec'] == 'none' and f['ext'] == audio_ext))
2128
2129 # These are the minimum required fields for a merged format

2149 # DEPRECATED OPTIONS
2150
2151 These are all the deprecated options and the current alternative to achieve the same effect
2152
2153 #### Almost redundant options
2154 While these options are almost the same as their new counterparts, there are some differences that prevents them being redundant
2155
2156 -j, --dump-json --print "%()j"
2157 -F, --list-formats --print formats_table
2158 --list-thumbnails --print thumbnails_table --print playlist:thumbnails_table
