77 # NEW FEATURES
78
79 * Merged with **youtube-dl v2021.12.17+ [commit/2dd6c6e](https://github.com/ytdl-org/youtube-dl/commit/2dd6c6e)** ([exceptions](https://github.com/yt-dlp/yt-dlp/issues/21)) and **youtube-dlc v2020.11.11-3+ [commit/f9401f2](https://github.com/blackjack4494/yt-dlc/commit/f9401f2a91987068139c5f757b12fc711d4c0cee)**: You get all the features and patches of [youtube-dlc](https://github.com/blackjack4494/yt-dlc) in addition to the latest [youtube-dl](https://github.com/ytdl-org/youtube-dl)
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, YouTube Music Albums/Channels ([except self-uploaded music](https://github.com/yt-dlp/yt-dlp/issues/723)), 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 * `255kbps` audio is extracted (if available) from YouTube Music when premium cookies are given
93 * Channel URLs download all uploads of the channel, including shorts and live
94
95 * **Cookies from browser**: Cookies can be automatically extracted from all major web browsers using `--cookies-from-browser BROWSER[+KEYRING][:PROFILE][::CONTAINER]`
96
97 * **Download time range**: Videos can be downloaded partially based on either timestamps or chapters using `--download-sections`
98
99 * **Split video by chapters**: Videos can be split into multiple files based on chapters using `--split-chapters`
100
101 * **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
102
103 * **Aria2c with HLS/DASH**: You can use `aria2c` as the external downloader for DASH(mpd) and HLS(m3u8) formats
104
105 * **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)
106
107 * **New MSOs**: Philo, Spectrum, SlingTV, Cablevision, RCN etc.
108
109 * **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
110
111 * **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`)
112
113 * **Portable Configuration**: Configuration files are automatically loaded from the home and root directories. See [CONFIGURATION](#configuration) for details
114
115 * **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`
116
117 * **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
118
119 * **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
120
121 * **Plugins**: Extractors and PostProcessors can be loaded from an external file. See [plugins](#plugins) for details
122
123 * **Self updater**: The releases can be updated using `yt-dlp -U`, and downgraded using `--update-to` if required
124
125 * **Nightly builds**: [Automated nightly builds](#update-channels) can be used with `--update-to nightly`
126
127 See [changelog](Changelog.md) or [commits](https://github.com/yt-dlp/yt-dlp/commits) for the full list of changes
128
129 Features marked with a **\*** have been back-ported to youtube-dl
130
131 ### Differences in default behavior
132
133 Some of yt-dlp's default options are different from that of youtube-dl and youtube-dlc:
134
135 * 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)
136 * The options `--auto-number` (`-A`), `--title` (`-t`) and `--literal` (`-l`), no longer work. See [removed options](#Removed) for details
137 * `avconv` is not supported as an alternative to `ffmpeg`
138 * yt-dlp stores config files in slightly different locations to youtube-dl. See [CONFIGURATION](#configuration) for a list of correct locations
139 * 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`
140 * 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
141 * 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
142 * 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
143 * `--no-abort-on-error` is enabled by default. Use `--abort-on-error` or `--compat-options abort-on-error` to abort on errors instead
144 * 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
145 * `--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
146 * 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
147 * `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
148 * The output of `-F` is listed in a new format. Use `--compat-options list-formats` to revert this
149 * 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
150 * 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
151 * Unavailable videos are also listed for YouTube playlists. Use `--compat-options no-youtube-unavailable-videos` to remove this
152 * 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.
153 * 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
154 * Thumbnail embedding in `mp4` is done with mutagen if possible. Use `--compat-options embed-thumbnail-atomicparsley` to force the use of AtomicParsley instead
155 * Some private fields such as filenames are removed by default from the infojson. Use `--no-clean-infojson` or `--compat-options no-clean-infojson` to revert this
156 * 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
157 * `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`
158 * 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
159 * 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
160
161 For ease of use, a few more compat options are available:
162
163 * `--compat-options all`: Use all compat options (Do NOT use)
164 * `--compat-options youtube-dl`: Same as `--compat-options all,-multistreams`
165 * `--compat-options youtube-dlc`: Same as `--compat-options all,-no-live-chat,-no-youtube-channel-redirect`
166 * `--compat-options 2021`: Same as `--compat-options 2022,no-certifi,filename-sanitization,no-youtube-prefer-utc-upload-date`
167 * `--compat-options 2022`: Same as `--compat-options no-external-downloader-progress`. Use this to enable all future compat options

180 <!-- MANPAGE: END EXCLUDED SECTION -->
181
182 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
183
184
185 ## UPDATE
186 You can use `yt-dlp -U` to update if you are using the [release binaries](#release-files)
187
188 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
189
190 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
191
192 <a id="update-channels"/>
193
194 There are currently two release channels for binaries, `stable` and `nightly`.
195 `stable` is the default channel, and many of its changes have been tested by users of the nightly channel.
196 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).
197
198 When using `--update`/`-U`, a release binary will only update to its current channel.
199 This release channel can be changed by using the `--update-to` option. `--update-to` can also be used to upgrade or downgrade to specific tags from a channel.
200
201 Example usage:
202 * `yt-dlp --update-to nightly` change to `nightly` channel and update to its latest release
203 * `yt-dlp --update-to stable@2023.02.17` upgrade/downgrade to release to `stable` channel tag `2023.02.17`
204 * `yt-dlp --update-to 2023.01.06` upgrade/downgrade to tag `2023.01.06` if it exists on the current channel

257 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.
258 -->
259
260 While all the other dependencies are optional, `ffmpeg` and `ffprobe` are highly recommended
261
262 ### Strongly recommended
263
264 * [**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)
265
266 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
267
268 **Important**: What you need is ffmpeg *binary*, **NOT** [the python package of the same name](https://pypi.org/project/ffmpeg)

294
295 To use or redistribute the dependencies, you must agree to their respective licensing terms.
296
297 The standalone release binaries are built with the Python interpreter and the packages marked with **\*** included.
298
299 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
300
301
302 ## COMPILE
303
304 ### Standalone PyInstaller Builds
305 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.
306
307 python3 -m pip install -U pyinstaller -r requirements.txt
308 python3 devscripts/make_lazy_extractors.py
309 python3 pyinst.py
310
311 On some systems, you may need to use `py` or `python` instead of `python3`.
312
313 `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).
314
315 **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.
316
317 **Important**: Running `pyinstaller` directly **without** using `pyinst.py` is **not** officially supported. This may or may not work correctly.
318
319 ### Platform-independent Binary (UNIX)
320 You will need the build tools `python` (3.7+), `zip`, `make` (GNU), `pandoc`\* and `pytest`\*.
321
322 After installing these, simply run `make`.
323
324 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)
325
326 ### Standalone Py2Exe Builds (Windows)
327
328 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.
329
330 If you wish to build it anyway, install Python and py2exe, and then simply run `setup.py py2exe`
331
332 py -m pip install -U py2exe -r requirements.txt
333 py devscripts/make_lazy_extractors.py
334 py setup.py py2exe
335
336 ### Related scripts
337
338 * **`devscripts/update-version.py`** - Update the version number based on current date.
339 * **`devscripts/set-variant.py`** - Set the build variant of the executable.
340 * **`devscripts/make_changelog.py`** - Create a markdown changelog using short commit messages and update `CONTRIBUTORS` file.
341 * **`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.
342
343 Note: See their `--help` for more info.
344
345 ### Forking the project
346 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.

348 # USAGE AND OPTIONS
349
350 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
351 yt-dlp [OPTIONS] [--] URL [URL...]
352
353 `Ctrl+F` is your friend :D
354 <!-- MANPAGE: END EXCLUDED SECTION -->
355
356 <!-- Auto generated -->
357 ## General Options:
358 -h, --help Print this help text and exit
359 --version Print program version and exit
360 -U, --update Update this program to the latest version
361 --no-update Do not check for updates (default)
362 --update-to [CHANNEL]@[TAG] Upgrade/downgrade to a specific version.
363 CHANNEL and TAG defaults to "stable" and
364 "latest" respectively if omitted; See
365 "UPDATE" for details. Supported channels:
366 stable, nightly
367 -i, --ignore-errors Ignore download and postprocessing errors.
368 The download will be considered successful
369 even if the postprocessing fails
370 --no-abort-on-error Continue with next video on download errors;
371 e.g. to skip unavailable videos in a
372 playlist (default)
373 --abort-on-error Abort downloading of further videos if an
374 error occurs (Alias: --no-ignore-errors)
375 --dump-user-agent Display the current user-agent and exit
376 --list-extractors List all supported extractors and exit
377 --extractor-descriptions Output descriptions of all supported
378 extractors and exit
379 --use-extractors NAMES Extractor names to use separated by commas.
380 You can also use regexes, "all", "default"
381 and "end" (end URL matching); e.g. --ies
382 "holodex.*,end,youtube". Prefix the name
383 with a "-" to exclude it, e.g. --ies
384 default,-generic. Use --list-extractors for
385 a list of extractor names. (Alias: --ies)
386 --default-search PREFIX Use this prefix for unqualified URLs. E.g.
387 "gvsearch2:python" downloads two videos from
388 google videos for the search term "python".
389 Use the value "auto" to let yt-dlp guess
390 ("auto_warning" to emit a warning when
391 guessing). "error" just throws an error. The
392 default value "fixup_error" repairs broken
393 URLs, but emits an error if this is not
394 possible instead of searching
395 --ignore-config Don't load any more configuration files
396 except those given by --config-locations.
397 For backward compatibility, if this option
398 is found inside the system configuration
399 file, the user configuration is not loaded.
400 (Alias: --no-config)
401 --no-config-locations Do not load any custom configuration files
402 (default). When given inside a configuration
403 file, ignore all previous --config-locations
404 defined in the current file
405 --config-locations PATH Location of the main configuration file;
406 either the path to the config or its
407 containing directory ("-" for stdin). Can be
408 used multiple times and inside other
409 configuration files
410 --flat-playlist Do not extract the videos of a playlist,
411 only list them
412 --no-flat-playlist Extract the videos of a playlist
413 --live-from-start Download livestreams from the start.
414 Currently only supported for YouTube
415 (Experimental)
416 --no-live-from-start Download livestreams from the current time
417 (default)
418 --wait-for-video MIN[-MAX] Wait for scheduled streams to become
419 available. Pass the minimum number of
420 seconds (or range) to wait between retries
421 --no-wait-for-video Do not wait for scheduled streams (default)
422 --mark-watched Mark videos watched (even with --simulate)
423 --no-mark-watched Do not mark videos watched (default)
424 --no-colors Do not emit color codes in output (Alias:
425 --no-colours)
426 --compat-options OPTS Options that can help keep compatibility
427 with youtube-dl or youtube-dlc
428 configurations by reverting some of the
429 changes made in yt-dlp. See "Differences in
430 default behavior" for details
431 --alias ALIASES OPTIONS Create aliases for an option string. Unless
432 an alias starts with a dash "-", it is
433 prefixed with "--". Arguments are parsed
434 according to the Python string formatting
435 mini-language. E.g. --alias get-audio,-X
436 "-S=aext:{0},abr -x --audio-format {0}"
437 creates options "--get-audio" and "-X" that
438 takes an argument (ARG0) and expands to
439 "-S=aext:ARG0,abr -x --audio-format ARG0".
440 All defined aliases are listed in the --help
441 output. Alias options can trigger more
442 aliases; so be careful to avoid defining
443 recursive options. As a safety measure, each
444 alias may be triggered a maximum of 100
445 times. This option can be used multiple times
446
447 ## Network Options:
448 --proxy URL Use the specified HTTP/HTTPS/SOCKS proxy. To
449 enable SOCKS proxy, specify a proper scheme,
450 e.g. socks5://user:pass@127.0.0.1:1080/.
451 Pass in an empty string (--proxy "") for
452 direct connection
453 --socket-timeout SECONDS Time to wait before giving up, in seconds
454 --source-address IP Client-side IP address to bind to
455 -4, --force-ipv4 Make all connections via IPv4
456 -6, --force-ipv6 Make all connections via IPv6
457 --enable-file-urls Enable file:// URLs. This is disabled by
458 default for security reasons.
459
460 ## Geo-restriction:
461 --geo-verification-proxy URL Use this proxy to verify the IP address for
462 some geo-restricted sites. The default proxy
463 specified by --proxy (or none, if the option
464 is not present) is used for the actual
465 downloading
466 --geo-bypass Bypass geographic restriction via faking
467 X-Forwarded-For HTTP header (default)
468 --no-geo-bypass Do not bypass geographic restriction via
469 faking X-Forwarded-For HTTP header
470 --geo-bypass-country CODE Force bypass geographic restriction with
471 explicitly provided two-letter ISO 3166-2
472 country code
473 --geo-bypass-ip-block IP_BLOCK Force bypass geographic restriction with
474 explicitly provided IP block in CIDR notation
475
476 ## Video Selection:
477 -I, --playlist-items ITEM_SPEC Comma separated playlist_index of the items
478 to download. You can specify a range using
479 "[START]:[STOP][:STEP]". For backward
480 compatibility, START-STOP is also supported.
481 Use negative indices to count from the right
482 and negative STEP to download in reverse
483 order. E.g. "-I 1:3,7,-5::2" used on a
484 playlist of size 15 will download the items
485 at index 1,2,3,7,11,13,15
486 --min-filesize SIZE Abort download if filesize is smaller than
487 SIZE, e.g. 50k or 44.6M
488 --max-filesize SIZE Abort download if filesize is larger than
489 SIZE, e.g. 50k or 44.6M
490 --date DATE Download only videos uploaded on this date.
491 The date can be "YYYYMMDD" or in the format
492 [now|today|yesterday][-N[day|week|month|year]].
493 E.g. "--date today-2weeks" downloads only
494 videos uploaded on the same day two weeks ago
495 --datebefore DATE Download only videos uploaded on or before
496 this date. The date formats accepted is the
497 same as --date
498 --dateafter DATE Download only videos uploaded on or after
499 this date. The date formats accepted is the
500 same as --date
501 --match-filters FILTER Generic video filter. Any "OUTPUT TEMPLATE"
502 field can be compared with a number or a
503 string using the operators defined in
504 "Filtering Formats". You can also simply
505 specify a field to match if the field is
506 present, use "!field" to check if the field
507 is not present, and "&" to check multiple
508 conditions. Use a "\" to escape "&" or
509 quotes if needed. If used multiple times,
510 the filter matches if atleast one of the
511 conditions are met. E.g. --match-filter
512 !is_live --match-filter "like_count>?100 &
513 description~='(?i)\bcats \& dogs\b'" matches
514 only videos that are not live OR those that
515 have a like count more than 100 (or the like
516 field is not available) and also has a
517 description that contains the phrase "cats &
518 dogs" (caseless). Use "--match-filter -" to
519 interactively ask whether to download each
520 video
521 --no-match-filter Do not use any --match-filter (default)
522 --break-match-filters FILTER Same as "--match-filters" but stops the
523 download process when a video is rejected
524 --no-break-match-filters Do not use any --break-match-filters (default)
525 --no-playlist Download only the video, if the URL refers
526 to a video and a playlist
527 --yes-playlist Download the playlist, if the URL refers to
528 a video and a playlist
529 --age-limit YEARS Download only videos suitable for the given
530 age
531 --download-archive FILE Download only videos not listed in the
532 archive file. Record the IDs of all
533 downloaded videos in it
534 --no-download-archive Do not use archive file (default)
535 --max-downloads NUMBER Abort after downloading NUMBER files
536 --break-on-existing Stop the download process when encountering
537 a file that is in the archive
538 --break-per-input Alters --max-downloads, --break-on-existing,
539 --break-match-filter, and autonumber to
540 reset per input URL
541 --no-break-per-input --break-on-existing and similar options
542 terminates the entire download queue
543 --skip-playlist-after-errors N Number of allowed failures until the rest of
544 the playlist is skipped
545
546 ## Download Options:
547 -N, --concurrent-fragments N Number of fragments of a dash/hlsnative
548 video that should be downloaded concurrently
549 (default is 1)
550 -r, --limit-rate RATE Maximum download rate in bytes per second,
551 e.g. 50K or 4.2M
552 --throttled-rate RATE Minimum download rate in bytes per second
553 below which throttling is assumed and the
554 video data is re-extracted, e.g. 100K
555 -R, --retries RETRIES Number of retries (default is 10), or
556 "infinite"
557 --file-access-retries RETRIES Number of times to retry on file access
558 error (default is 3), or "infinite"
559 --fragment-retries RETRIES Number of retries for a fragment (default is
560 10), or "infinite" (DASH, hlsnative and ISM)
561 --retry-sleep [TYPE:]EXPR Time to sleep between retries in seconds
562 (optionally) prefixed by the type of retry
563 (http (default), fragment, file_access,
564 extractor) to apply the sleep to. EXPR can
565 be a number, linear=START[:END[:STEP=1]] or
566 exp=START[:END[:BASE=2]]. This option can be
567 used multiple times to set the sleep for the
568 different retry types, e.g. --retry-sleep
569 linear=1::2 --retry-sleep fragment:exp=1:20
570 --skip-unavailable-fragments Skip unavailable fragments for DASH,
571 hlsnative and ISM downloads (default)
572 (Alias: --no-abort-on-unavailable-fragments)
573 --abort-on-unavailable-fragments
574 Abort download if a fragment is unavailable
575 (Alias: --no-skip-unavailable-fragments)

589 bandwidth throttling imposed by a webserver
590 (experimental)
591 --playlist-random Download playlist videos in random order
592 --lazy-playlist Process entries in the playlist as they are
593 received. This disables n_entries,
594 --playlist-random and --playlist-reverse
595 --no-lazy-playlist Process videos in the playlist only after
596 the entire playlist is parsed (default)
597 --xattr-set-filesize Set file xattribute ytdl.filesize with
598 expected file size
599 --hls-use-mpegts Use the mpegts container for HLS videos;
600 allowing some players to play the video
601 while downloading, and reducing the chance
602 of file corruption if download is
603 interrupted. This is enabled by default for
604 live streams
605 --no-hls-use-mpegts Do not use the mpegts container for HLS
606 videos. This is default when not downloading
607 live streams
608 --download-sections REGEX Download only chapters whose title matches
609 the given regular expression. Time ranges
610 prefixed by a "*" can also be used in place
611 of chapters to download the specified range.

613 multiple times to download multiple
614 sections, e.g. --download-sections
615 "*10:15-inf" --download-sections "intro"
616 --downloader [PROTO:]NAME Name or path of the external downloader to
617 use (optionally) prefixed by the protocols
618 (http, ftp, m3u8, dash, rstp, rtmp, mms) to
619 use it for. Currently supports native,
620 aria2c, avconv, axel, curl, ffmpeg, httpie,
621 wget. You can use this option multiple times
622 to set different downloaders for different
623 protocols. E.g. --downloader aria2c
624 --downloader "dash,m3u8:native" will use
625 aria2c for http/ftp downloads, and the
626 native downloader for dash/m3u8 downloads
627 (Alias: --external-downloader)
628 --downloader-args NAME:ARGS Give these arguments to the external
629 downloader. Specify the downloader name and
630 the arguments separated by a colon ":". For
631 ffmpeg, arguments can be passed to different
632 positions using the same syntax as
633 --postprocessor-args. You can use this
634 option multiple times to give different
635 arguments to different downloaders (Alias:
636 --external-downloader-args)
637
638 ## Filesystem Options:
639 -a, --batch-file FILE File containing URLs to download ("-" for
640 stdin), one URL per line. Lines starting
641 with "#", ";" or "]" are considered as
642 comments and ignored
643 --no-batch-file Do not read URLs from batch file (default)
644 -P, --paths [TYPES:]PATH The paths where the files should be
645 downloaded. Specify the type of file and the
646 path separated by a colon ":". All the same
647 TYPES as --output are supported.
648 Additionally, you can also provide "home"
649 (default) and "temp" paths. All intermediary
650 files are first downloaded to the temp path
651 and then the final files are moved over to
652 the home path after download is finished.
653 This option is ignored if --output is an
654 absolute path
655 -o, --output [TYPES:]TEMPLATE Output filename template; see "OUTPUT
656 TEMPLATE" for details
657 --output-na-placeholder TEXT Placeholder for unavailable fields in
658 "OUTPUT TEMPLATE" (default: "NA")
659 --restrict-filenames Restrict filenames to only ASCII characters,
660 and avoid "&" and spaces in filenames
661 --no-restrict-filenames Allow Unicode characters, "&" and spaces in
662 filenames (default)
663 --windows-filenames Force filenames to be Windows-compatible
664 --no-windows-filenames Make filenames Windows-compatible only if
665 using Windows (default)
666 --trim-filenames LENGTH Limit the filename length (excluding
667 extension) to the specified number of
668 characters
669 -w, --no-overwrites Do not overwrite any files
670 --force-overwrites Overwrite all video and metadata files. This
671 option includes --no-continue
672 --no-force-overwrites Do not overwrite the video, but overwrite
673 related files (default)
674 -c, --continue Resume partially downloaded files/fragments

1173 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:
1174 ```
1175 # Lines starting with # are comments
1176
1177 # Always extract audio
1178 -x
1179
1180 # Do not copy the mtime
1181 --no-mtime
1182
1183 # Use this proxy
1184 --proxy 127.0.0.1:3128
1185
1186 # Save all videos under YouTube directory in your home directory
1187 -o ~/YouTube/%(title)s.%(ext)s
1188 ```
1189
1190 **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.
1191
1192 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.
1193
1194 ### Configuration file encoding
1195
1196 The configuration files are decoded according to the UTF BOM if present, and in the encoding from system locale otherwise.
1197
1198 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.
1199
1200 ### Authentication with `.netrc` file
1201
1202 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:
1203 ```
1204 touch ${HOME}/.netrc
1205 chmod a-rwx,u+rw ${HOME}/.netrc
1206 ```
1207 After that you can add credentials for an extractor in the following format, where *extractor* is the name of the extractor in lowercase:
1208 ```
1209 machine <extractor> login <username> password <password>
1210 ```
1211 E.g.
1212 ```
1213 machine youtube login myaccount@gmail.com password my_youtube_password
1214 machine twitch login my_twitch_account_name password my_twitch_password
1215 ```
1216 To activate authentication with the `.netrc` file you should pass `--netrc` to yt-dlp or place it in the [configuration file](#configuration).
1217
1218 The default location of the .netrc file is `~` (see below).
1219
1220 ### Notes about environment variables
1221 * Environment variables are normally specified as `${VARIABLE}`/`$VARIABLE` on UNIX and `%VARIABLE%` on Windows; but is always shown as `${VARIABLE}` in this documentation
1222 * yt-dlp also allow using UNIX-style variables on Windows for path-like options; e.g. `--output`, `--config-location`
1223 * If unset, `${XDG_CONFIG_HOME}` defaults to `~/.config` and `${XDG_CACHE_HOME}` to `~/.cache`
1224 * On Windows, `~` points to `${HOME}` if present; or, `${USERPROFILE}` or `${HOMEDRIVE}${HOMEPATH}` otherwise
1225 * On Windows, `${USERPROFILE}` generally points to `C:\Users\<user name>` and `${APPDATA}` to `${USERPROFILE}\AppData\Roaming`
1226
1227 # OUTPUT TEMPLATE
1228
1229 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.
1230
1231 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
1232 **tl;dr:** [navigate me to examples](#output-template-examples).
1233 <!-- MANPAGE: END EXCLUDED SECTION -->
1234
1235 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).
1236
1237 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.
1238
1239 The field names themselves (the part inside the parenthesis) can also have some special formatting:
1240
1241 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
1242
1243 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`
1244
1245 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`
1246
1247 1. **Alternatives**: Alternate fields can be specified separated with a `,`. E.g. `%(release_date>%Y,upload_date>%Y|Unknown)s`
1248
1249 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`
1250
1251 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`
1252
1253 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)
1254
1255 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
1256
1257 To summarize, the general syntax for a field is:
1258 ```
1259 %(name[.keys][addition][>strf][,alternate][&replacement][|default])[flags][width][.precision][length]type
1260 ```
1261
1262 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.
1263
1264 <a id="outtmpl-postprocess-note"/>
1265
1266 **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.

1384
1385 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.
1386
1387 **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).
1388
1389 **Tip**: Look at the `-j` output to identify which fields are available for the particular URL
1390
1391 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`.
1392
1393 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.
1394
1395 To use percent literals in an output template use `%%`. To output to stdout use `-o -`.
1396
1397 The current default template is `%(title)s [%(id)s].%(ext)s`.
1398
1399 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.
1400

1438 # Stream the video being downloaded to stdout
1439 $ yt-dlp -o - BaW_jenozKc
1440 ```
1441
1442 # FORMAT SELECTION
1443
1444 By default, yt-dlp tries to download the best available quality if you **don't** pass any options.
1445 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`.
1446
1447 **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.
1448
1449 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.
1450
1451 <!-- MANPAGE: BEGIN EXCLUDED SECTION -->
1452 **tl;dr:** [navigate me to examples](#format-selection-examples).
1453 <!-- MANPAGE: END EXCLUDED SECTION -->
1454
1455 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.
1456
1457 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.
1458
1459 You can use `-f -` to interactively provide the format selector *for each video*
1460
1461 You can also use special names to select particular edge case formats:
1462
1463 - `all`: Select **all formats** separately
1464 - `mergeall`: Select and **merge all formats** (Must be used with `--audio-multistreams`, `--video-multistreams` or both)
1465 - `b*`, `best*`: Select the best quality format that **contains either** a video or an audio or both (ie; `vcodec!=none or acodec!=none`)
1466 - `b`, `best`: Select the best quality format that **contains both** video and audio. Equivalent to `best*[vcodec!=none][acodec!=none]`
1467 - `bv`, `bestvideo`: Select the best quality **video-only** format. Equivalent to `best*[acodec=none]`
1468 - `bv*`, `bestvideo*`: Select the best quality format that **contains video**. It may also contain audio. Equivalent to `best*[vcodec!=none]`
1469 - `ba`, `bestaudio`: Select the best quality **audio-only** format. Equivalent to `best*[vcodec=none]`
1470 - `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))
1471 - `w*`, `worst*`: Select the worst quality format that contains either a video or an audio
1472 - `w`, `worst`: Select the worst quality format that contains both video and audio. Equivalent to `worst*[vcodec!=none][acodec!=none]`
1473 - `wv`, `worstvideo`: Select the worst quality video-only format. Equivalent to `worst*[acodec=none]`
1474 - `wv*`, `worstvideo*`: Select the worst quality format that contains video. It may also contain audio. Equivalent to `worst*[vcodec!=none]`
1475 - `wa`, `worstaudio`: Select the worst quality audio-only format. Equivalent to `worst*[vcodec=none]`
1476 - `wa*`, `worstaudio*`: Select the worst quality format that contains audio. It may also contain video. Equivalent to `worst*[acodec!=none]`
1477
1478 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.
1479
1480 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.
1481
1482 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.
1483
1484 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`.
1485
1486 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.
1487
1488 **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
1489
1490 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`.
1491
1492 ## Filtering Formats
1493
1494 You can also filter the video formats by putting a condition in brackets, as in `-f "best[height=720]"` (or `-f "[filesize>10M]"`).
1495
1496 The following numeric meta fields can be used with comparisons `<`, `<=`, `>`, `>=`, `=` (equals), `!=` (not equals):
1497
1498 - `filesize`: The number of bytes, if known in advance
1499 - `filesize_approx`: An estimate for the number of bytes
1500 - `width`: Width of the video, if known
1501 - `height`: Height of the video, if known
1502 - `aspect_ratio`: Aspect ratio of the video, if known
1503 - `tbr`: Average bitrate of audio and video in KBit/s
1504 - `abr`: Average audio bitrate in KBit/s
1505 - `vbr`: Average video bitrate in KBit/s
1506 - `asr`: Audio sampling rate in Hertz
1507 - `fps`: Frame rate
1508 - `audio_channels`: The number of audio channels
1509 - `stretched_ratio`: `width:height` of the video's pixels, if not square
1510
1511 Also filtering work for comparisons `=` (equals), `^=` (starts with), `$=` (ends with), `*=` (contains), `~=` (matches regex) and following string meta fields:
1512
1513 - `url`: Video URL
1514 - `ext`: File extension
1515 - `acodec`: Name of the audio codec in use
1516 - `vcodec`: Name of the video codec in use
1517 - `container`: Name of the container format
1518 - `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`)
1519 - `language`: Language code
1520 - `dynamic_range`: The dynamic range of the video
1521 - `format_id`: A short description of the format
1522 - `format`: A human-readable description of the format
1523 - `format_note`: Additional info about the format
1524 - `resolution`: Textual description of width and height
1525
1526 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 `._-`.
1527
1528 **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.
1529
1530 Formats for which the value is not known are excluded unless you put a question mark (`?`) after the operator. You can combine format filters, so `-f "[height<=?720][tbr>500]"` selects up to 720p videos (or videos where the height is not known) with a bitrate of at least 500 KBit/s. You can also use the filters with `all` to download all formats that satisfy the filter, e.g. `-f "all[vcodec=none]"` selects all audio-only formats.
1531
1532 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.
1533
1534 ## Sorting Formats
1535
1536 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...`.
1537
1538 The available fields are:
1539
1540 - `hasvid`: Gives priority to formats that have a video stream
1541 - `hasaud`: Gives priority to formats that have an audio stream
1542 - `ie_pref`: The format preference
1543 - `lang`: The language preference
1544 - `quality`: The quality of the format
1545 - `source`: The preference of the source
1546 - `proto`: Protocol used for download (`https`/`ftps` > `http`/`ftp` > `m3u8_native`/`m3u8` > `http_dash_segments`> `websocket_frag` > `mms`/`rtsp` > `f4f`/`f4m`)
1547 - `vcodec`: Video Codec (`av01` > `vp9.2` > `vp9` > `h265` > `h264` > `vp8` > `h263` > `theora` > other)
1548 - `acodec`: Audio Codec (`flac`/`alac` > `wav`/`aiff` > `opus` > `vorbis` > `aac` > `mp4a` > `mp3` > `ac4` > `eac3` > `ac3` > `dts` > other)
1549 - `codec`: Equivalent to `vcodec,acodec`
1550 - `vext`: Video Extension (`mp4` > `mov` > `webm` > `flv` > other). If `--prefer-free-formats` is used, `webm` is preferred.
1551 - `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`
1552 - `ext`: Equivalent to `vext,aext`
1553 - `filesize`: Exact filesize, if known in advance
1554 - `fs_approx`: Approximate filesize calculated from the manifests
1555 - `size`: Exact filesize if available, otherwise approximate filesize
1556 - `height`: Height of video
1557 - `width`: Width of video
1558 - `res`: Video resolution, calculated as the smallest dimension.
1559 - `fps`: Framerate of video
1560 - `hdr`: The dynamic range of the video (`DV` > `HDR12` > `HDR10+` > `HDR10` > `HLG` > `SDR`)
1561 - `channels`: The number of audio channels
1562 - `tbr`: Total average bitrate in KBit/s
1563 - `vbr`: Average video bitrate in KBit/s
1564 - `abr`: Average audio bitrate in KBit/s
1565 - `br`: Equivalent to using `tbr,vbr,abr`
1566 - `asr`: Audio sample rate in Hz
1567
1568 **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.
1569
1570 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.
1571
1572 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.
1573
1574 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.
1575
1576 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`.
1577
1578 **Tip**: You can use the `-v -F` to see how the formats have been sorted (worst to best).
1579
1580 ## Format Selection examples
1581
1582 ```bash
1583 # Download and merge the best video-only format and the best audio-only format,

1592 $ yt-dlp
1593
1594 # Download the best video-only format and the best audio-only format without merging them

1700 $ yt-dlp -S "+res:480,codec,br"
1701 ```
1702
1703 # MODIFYING METADATA
1704
1705 The metadata obtained by the extractors can be modified by using `--parse-metadata` and `--replace-in-metadata`
1706
1707 `--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.
1708
1709 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.
1710
1711 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`.
1712
1713 This option also has a few special uses:
1714
1715 * 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
1716
1717 * 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.
1718
1719 **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.
1720
1721 For reference, these are the fields yt-dlp adds by default to the file metadata:
1722
1723 Metadata fields | From
1724 :--------------------------|:------------------------------------------------
1725 `title` | `track` or `title`
1726 `date` | `upload_date`
1727 `description`, `synopsis` | `description`
1728 `purl`, `comment` | `webpage_url`
1729 `track` | `track_number`
1730 `artist` | `artist`, `creator`, `uploader` or `uploader_id`
1731 `genre` | `genre`
1732 `album` | `album`
1733 `album_artist` | `album_artist`
1734 `disc` | `disc_number`
1735 `show` | `series`
1736 `season_number` | `season_number`
1737 `episode_id` | `episode` or `episode_id`
1738 `episode_sort` | `episode_number`
1739 `language` of each stream | the format's `language`
1740
1741 **Note**: The file format may not support some of these fields
1742
1743
1744 ## Modifying metadata examples
1745
1746 ```bash
1747 # Interpret the title as "Artist - Title"
1748 $ yt-dlp --parse-metadata "title:%(artist)s - %(title)s"
1749
1750 # Regex example
1751 $ yt-dlp --parse-metadata "description:Artist - (?P<artist>.+)"
1752
1753 # Set title as "Series name S01E05"
1754 $ yt-dlp --parse-metadata "%(series)s S%(season_number)02dE%(episode_number)02d:%(title)s"
1755
1756 # Prioritize uploader as the "artist" field in video metadata
1757 $ yt-dlp --parse-metadata "%(uploader|)s:%(meta_artist)s" --embed-metadata
1758
1759 # Set "comment" field in video metadata using description instead of webpage_url,
1760 # handling multiple lines correctly
1761 $ yt-dlp --parse-metadata "description:(?s)(?P<meta_comment>.+)" --embed-metadata
1762
1763 # Do not set any "synopsis" in the video metadata
1764 $ yt-dlp --parse-metadata ":(?P<meta_synopsis>)"
1765
1766 # Remove "formats" field from the infojson by setting it to an empty string
1767 $ yt-dlp --parse-metadata ":(?P<formats>)" -j
1768
1769 # Replace all spaces and "_" in title and uploader with a `-`
1770 $ yt-dlp --replace-in-metadata "title,uploader" "[ _]" "-"
1771
1772 ```
1773
1774 # EXTRACTOR ARGUMENTS
1775
1776 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"`
1777
1778 Note: In CLI, `ARG` can use `-` instead of `_`; e.g. `youtube:player-client"` becomes `youtube:player_client"`
1779
1780 The following extractors use this feature:
1781
1782 #### youtube
1783 * `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
1784 * `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
1785 * `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` and `tv_embedded` (agegate bypass) with no variants. By default, `android,web` is used, but `tv_embedded` and `creator` variants are added as required for age-gated videos. Similarly, the music variants are added for `music.youtube.com` urls. You can use `all` to use all the clients, and `default` for the default clients.
1786 * `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
1787 * `comment_sort`: `top` or `new` (default) - choose comment sorting mode (on YouTube's side)
1788 * `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`
1789 * 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
1790 * `include_duplicate_formats`: Extract formats with identical content but different URLs or protocol. This is useful if some of the formats are unavailable or throttled.
1791 * `include_incomplete_formats`: Extract formats that cannot be downloaded completely (live dash and post-live m3u8)
1792 * `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
1793 * `innertube_key`: Innertube API key to use for all API requests
1794
1795 #### youtubetab (YouTube playlists, channels, feeds, etc.)
1796 * `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)
1797 * `approximate_date`: Extract approximate `upload_date` and `timestamp` in flat-playlist. This may cause date-based filters to be slightly off
1798
1799 #### generic
1800 * `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
1801 * `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`
1802 * `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
1803 * `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`
1804
1805 #### funimation
1806 * `language`: Audio languages to extract, e.g. `funimation:language=english,japanese`
1807 * `version`: The video version to extract - `uncut` or `simulcast`
1808
1809 #### crunchyrollbeta (Crunchyroll)
1810 * `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`
1811 * `hardsub`: Preference order for which hardsub versions to extract, or `all` (default: `None` = no hardsubs), e.g. `crunchyrollbeta:hardsub=en-US,None`
1812
1813 #### vikichannel
1814 * `video_types`: Types of videos to download - one or more of `episodes`, `movies`, `clips`, `trailers`
1815
1816 #### niconico
1817 * `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.**
1818
1819 #### youtubewebarchive

1821
1822 #### gamejolt
1823 * `comment_sort`: `hot` (default), `you` (cookies needed), `top`, `new` - choose comment sorting mode (on GameJolt's side)
1824
1825 #### hotstar
1826 * `res`: resolution to ignore - one or more of `sd`, `hd`, `fhd`
1827 * `vcodec`: vcodec to ignore - one or more of `h264`, `h265`, `dvh265`
1828 * `dr`: dynamic range to ignore - one or more of `sdr`, `hdr10`, `dv`
1829

1846 # PLUGINS
1847
1848 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!**
1849
1850 Plugins can be of `<type>`s `extractor` or `postprocessor`.
1851 - Extractor plugins do not need to be enabled from the CLI and are automatically invoked when the input URL is suitable for it.
1852 - Extractor plugins take priority over builtin extractors.
1853 - Postprocessor plugins can be invoked using `--use-postprocessor NAME`.
1854
1855
1856 Plugins are loaded from the namespace packages `yt_dlp_plugins.extractor` and `yt_dlp_plugins.postprocessor`.
1857
1858 In other words, the file structure on the disk looks something like:
1859
1860 yt_dlp_plugins/
1861 extractor/
1862 myplugin.py
1863 postprocessor/
1864 myplugin.py
1865
1866 yt-dlp looks for these `yt_dlp_plugins` namespace folders in many locations (see below) and loads in plugins from **all** of them.
1867
1868 See the [wiki for some known plugins](https://github.com/yt-dlp/yt-dlp/wiki/Plugins)
1869
1870 ## Installing Plugins
1871
1872 Plugins can be installed using various methods and locations.
1873
1874 1. **Configuration directories**:
1875 Plugin packages (containing a `yt_dlp_plugins` namespace folder) can be dropped into the following standard [configuration locations](#configuration):
1876 * **User Plugins**
1877 * `${XDG_CONFIG_HOME}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Linux/macOS)
1878 * `${XDG_CONFIG_HOME}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1879 * `${APPDATA}/yt-dlp/plugins/<package name>/yt_dlp_plugins/` (recommended on Windows)
1880 * `${APPDATA}/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1881 * `~/.yt-dlp/plugins/<package name>/yt_dlp_plugins/`
1882 * `~/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1883 * **System Plugins**
1884 * `/etc/yt-dlp/plugins/<package name>/yt_dlp_plugins/`
1885 * `/etc/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1886 2. **Executable location**: Plugin packages can similarly be installed in a `yt-dlp-plugins` directory under the executable location:
1887 * Binary: where `<root-dir>/yt-dlp.exe`, `<root-dir>/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1888 * Source: where `<root-dir>/yt_dlp/__main__.py`, `<root-dir>/yt-dlp-plugins/<package name>/yt_dlp_plugins/`
1889
1890 3. **pip and other locations in `PYTHONPATH`**
1891 * 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.
1892 * Note: plugin files between plugin packages installed with pip must have unique filenames.
1893 * Any path in `PYTHONPATH` is searched in for the `yt_dlp_plugins` namespace folder.
1894 * Note: This does not apply for Pyinstaller/py2exe builds.
1895
1896
1897 `.zip`, `.egg` and `.whl` archives containing a `yt_dlp_plugins` namespace folder in their root are also supported as plugin packages.
1898 * e.g. `${XDG_CONFIG_HOME}/yt-dlp/plugins/mypluginpkg.zip` where `mypluginpkg.zip` contains `yt_dlp_plugins/<type>/myplugin.py`
1899
1900 Run yt-dlp with `--verbose` to check if the plugin has been loaded.
1901
1902 ## Developing Plugins
1903
1904 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.
1905
1906 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`).
1907
1908 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.
1909
1910 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.
1911
1912 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.
1913
1914 # EMBEDDING YT-DLP
1915
1916 yt-dlp makes the best effort to be a good command-line program, and thus should be callable from any programming language.
1917
1918 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.
1919
1920 From a Python program, you can embed yt-dlp in a more powerful fashion, like this:
1921
1922 ```python
1923 from yt_dlp import YoutubeDL
1924
1925 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
1926 with YoutubeDL() as ydl:
1927 ydl.download(URLS)
1928 ```
1929
1930 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#L184).
1931
1932 **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)
1933
1934 ## Embedding examples
1935
1936 #### Extracting information
1937
1938 ```python
1939 import json
1940 import yt_dlp
1941
1942 URL = 'https://www.youtube.com/watch?v=BaW_jenozKc'
1943
1944 # ℹ️ See help(yt_dlp.YoutubeDL) for a list of available options and public functions
1945 ydl_opts = {}
1946 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
1947 info = ydl.extract_info(URL, download=False)
1948
1949 # ℹ️ ydl.sanitize_info makes the info json-serializable
1950 print(json.dumps(ydl.sanitize_info(info)))
1951 ```
1952 #### Download using an info-json
1953
1954 ```python
1955 import yt_dlp
1956
1957 INFO_FILE = 'path/to/video.info.json'
1958
1959 with yt_dlp.YoutubeDL() as ydl:
1960 error_code = ydl.download_with_info_file(INFO_FILE)
1961
1962 print('Some videos failed to download' if error_code
1963 else 'All videos successfully downloaded')
1964 ```
1965
1966 #### Extract audio
1967
1968 ```python
1969 import yt_dlp
1970
1971 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
1972
1973 ydl_opts = {
1974 'format': 'm4a/bestaudio/best',
1975 # ℹ️ See help(yt_dlp.postprocessor) for a list of available Postprocessors and their arguments
1976 'postprocessors': [{ # Extract audio using ffmpeg
1977 'key': 'FFmpegExtractAudio',
1978 'preferredcodec': 'm4a',
1979 }]
1980 }
1981
1982 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
1983 error_code = ydl.download(URLS)
1984 ```
1985
1986 #### Filter videos
1987
1988 ```python
1989 import yt_dlp
1990
1991 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
1992
1993 def longer_than_a_minute(info, *, incomplete):
1994 """Download only videos longer than a minute (or with unknown duration)"""
1995 duration = info.get('duration')
1996 if duration and duration < 60:
1997 return 'The video is too short'
1998
1999 ydl_opts = {
2000 'match_filter': longer_than_a_minute,
2001 }
2002
2003 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
2004 error_code = ydl.download(URLS)
2005 ```
2006
2007 #### Adding logger and progress hook
2008
2009 ```python
2010 import yt_dlp
2011
2012 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
2013
2014 class MyLogger:
2015 def debug(self, msg):
2016 # For compatibility with youtube-dl, both debug and info are passed into debug
2017 # You can distinguish them by the prefix '[debug] '
2018 if msg.startswith('[debug] '):
2019 pass
2020 else:
2021 self.info(msg)
2022
2023 def info(self, msg):
2024 pass
2025
2026 def warning(self, msg):
2027 pass
2028
2029 def error(self, msg):
2030 print(msg)
2031
2032
2033 # ℹ️ See "progress_hooks" in help(yt_dlp.YoutubeDL)
2034 def my_hook(d):
2035 if d['status'] == 'finished':
2036 print('Done downloading, now post-processing ...')
2037
2038
2039 ydl_opts = {
2040 'logger': MyLogger(),
2041 'progress_hooks': [my_hook],
2042 }
2043
2044 with yt_dlp.YoutubeDL(ydl_opts) as ydl:
2045 ydl.download(URLS)
2046 ```
2047
2048 #### Add a custom PostProcessor
2049
2050 ```python
2051 import yt_dlp
2052
2053 URLS = ['https://www.youtube.com/watch?v=BaW_jenozKc']
2054
2055 # ℹ️ See help(yt_dlp.postprocessor.PostProcessor)
2056 class MyCustomPP(yt_dlp.postprocessor.PostProcessor):
2057 def run(self, info):
2058 self.to_screen('Doing stuff')
2059 return [], info
2060
2061
2062 with yt_dlp.YoutubeDL() as ydl:
2063 # ℹ️ "when" can take any value in yt_dlp.utils.POSTPROCESS_WHEN
2064 ydl.add_post_processor(MyCustomPP(), when='pre_process')
2065 ydl.download(URLS)
2066 ```
2067
2068
2069 #### Use a custom format selector
2070
2071 ```python
2072 import yt_dlp
2073
2074 URL = ['https://www.youtube.com/watch?v=BaW_jenozKc']
2075
2076 def format_selector(ctx):
2077 """ Select the best video and the best audio that won't result in an mkv.
2078 NOTE: This is just an example and does not handle all cases """
2079
2080 # formats are already sorted worst to best
2081 formats = ctx.get('formats')[::-1]
2082
2083 # acodec='none' means there is no audio
2084 best_video = next(f for f in formats
2085 if f['vcodec'] != 'none' and f['acodec'] == 'none')
2086
2087 # find compatible audio extension
2088 audio_ext = {'mp4': 'm4a', 'webm': 'webm'}[best_video['ext']]
2089 # vcodec='none' means there is no video
2090 best_audio = next(f for f in formats if (
2091 f['acodec'] != 'none' and f['vcodec'] == 'none' and f['ext'] == audio_ext))
2092
2093 # These are the minimum required fields for a merged format
2094 yield {
2095 'format_id': f'{best_video["format_id"]}+{best_audio["format_id"]}',
2096 'ext': best_video['ext'],
2097 'requested_formats': [best_video, best_audio],
2098 # Must be + separated list of protocols
