NAME

       yt-dlp - A youtube-dl fork with additional features and patches

SYNOPSIS

       yt-dlp [OPTIONS] URL [URL...]

DESCRIPTION

       yt-dlp  is  a  youtube-dl  (https://github.com/ytdl-org/youtube-dl)  fork based on the now
       inactive youtube-dlc (https://github.com/blackjack4494/yt-dlc).  The main  focus  of  this
       project is adding new features and patches while also keeping up to date with the original
       project

OPTIONS

   General Options:
       -h, --help
              Print this help text and exit

       --version
              Print program version and exit

       -U, --update
              Update this program to the latest version

       --no-update
              Do not check for updates (default)

       --update-to [CHANNEL]@[TAG]
              Upgrade/downgrade to a specific version.  CHANNEL and TAG defaults to "stable"  and
              "latest"  respectively  if  omitted; See "UPDATE" for details.  Supported channels:
              stable, nightly

       -i, --ignore-errors
              Ignore download  and  postprocessing  errors.   The  download  will  be  considered
              successful even if the postprocessing fails

       --no-abort-on-error
              Continue  with next video on download errors; e.g.  to skip unavailable videos in a
              playlist (default)

       --abort-on-error
              Abort downloading of further videos if an error occurs (Alias: --no-ignore-errors)

       --dump-user-agent
              Display the current user-agent and exit

       --list-extractors
              List all supported extractors and exit

       --extractor-descriptions
              Output descriptions of all supported extractors and exit

       --use-extractors NAMES
              Extractor names to use separated by commas.   You  can  also  use  regexes,  "all",
              "default"  and  "end"  (end  URL  matching);  e.g.   --ies "holodex.*,end,youtube".
              Prefix the name with a "-"  to  exclude  it,  e.g.   --ies  default,-generic.   Use
              --list-extractors for a list of extractor names.  (Alias: --ies)

       --default-search PREFIX
              Use  this  prefix  for  unqualified  URLs.   E.g.  "gvsearch2:python" downloads two
              videos from google videos for the search term "python".  Use the  value  "auto"  to
              let  yt-dlp  guess  ("auto_warning" to emit a warning when guessing).  "error" just
              throws an error.  The default value "fixup_error" repairs broken URLs, but emits an
              error if this is not possible instead of searching

       --ignore-config
              Don't  load  any more configuration files except those given by --config-locations.
              For backward compatibility, if this option is found inside the system configuration
              file, the user configuration is not loaded.  (Alias: --no-config)

       --no-config-locations
              Do  not  load  any  custom  configuration  files  (default).   When  given inside a
              configuration file, ignore all previous --config-locations defined in  the  current
              file

       --config-locations PATH
              Location  of  the  main  configuration  file;  either the path to the config or its
              containing directory ("-" for stdin).  Can be used multiple times and inside  other
              configuration files

       --flat-playlist

              (Experimental)

       --no-live-from-start
              Download livestreams from the current time (default)

       --wait-for-video MIN[-MAX]
              Wait for scheduled streams to become available.  Pass the minimum number of seconds
              (or range) to wait between retries

       --no-wait-for-video
              Do not wait for scheduled streams (default)

       --mark-watched
              Mark videos watched (even with --simulate)

       --no-mark-watched
              Do not mark videos watched (default)

       --no-colors
              Do not emit color codes in output (Alias: --no-colours)

       --compat-options OPTS
              Options   that   can   help  keep  compatibility  with  youtube-dl  or  youtube-dlc
              configurations by reverting some of the changes made in yt-dlp.   See  "Differences
              in default behavior" for details

       --alias ALIASES OPTIONS
              Create aliases for an option string.  Unless an alias starts with a dash "-", it is
              prefixed with "--".  Arguments are parsed according to the Python string formatting
              mini-language.   E.g.  --alias get-audio,-X "-S=aext:{0},abr -x --audio-format {0}"
              creates options "--get-audio" and "-X" that takes an argument (ARG0) and expands to
              "-S=aext:ARG0,abr  -x  --audio-format ARG0".  All defined aliases are listed in the
              --help output.  Alias options can trigger more aliases;  so  be  careful  to  avoid
              defining  recursive  options.   As  a safety measure, each alias may be triggered a
              maximum of 100 times.  This option can be used multiple times

   Network Options:
       --proxy URL
              Use the specified HTTP/HTTPS/SOCKS proxy.  To enable SOCKS proxy, specify a  proper
              scheme, e.g.  socks5://user:pass@127.0.0.1:1080/.  Pass in an empty string (--proxy
              "") for direct connection

       --socket-timeout SECONDS
              Time to wait before giving up, in seconds

       --source-address IP
              Client-side IP address to bind to

              Make all connections via IPv6

       --enable-file-urls
              Enable file:// URLs.  This is disabled by default for security reasons.

   Geo-restriction:
       --geo-verification-proxy URL
              Use this proxy to verify the IP address for some geo-restricted sites.  The default
              proxy  specified by --proxy (or none, if the option is not present) is used for the
              actual downloading

       --geo-bypass
              Bypass geographic restriction via faking X-Forwarded-For HTTP header (default)

       --no-geo-bypass

       --geo-bypass-country CODE
              Force bypass geographic restriction with explicitly provided two-letter ISO  3166-2
              country code

       --geo-bypass-ip-block IP_BLOCK
              Force  bypass  geographic  restriction  with  explicitly  provided IP block in CIDR
              notation

   Video Selection:
       -I, --playlist-items ITEM_SPEC
              Comma separated playlist_index of the items to download.  You can specify  a  range
              using  "[START]:[STOP][:STEP]".   For  backward  compatibility,  START-STOP is also
              supported.  Use negative indices to count from  the  right  and  negative  STEP  to
              download  in  reverse  order.  E.g.  "-I 1:3,7,-5::2" used on a playlist of size 15
              will download the items at index 1,2,3,7,11,13,15

       --min-filesize SIZE
              Abort download if filesize is smaller than SIZE, e.g.  50k or 44.6M

       --max-filesize SIZE
              Abort download if filesize is larger than SIZE, e.g.  50k or 44.6M

       --date DATE
              Download only videos uploaded on this date.  The date can be "YYYYMMDD" or  in  the

              the same as --date

       --dateafter DATE
              Download  only videos uploaded on or after this date.  The date formats accepted is
              the same as --date

       --match-filters FILTER
              Generic video filter.  Any "OUTPUT TEMPLATE" field can be compared with a number or
              a  string  using the operators defined in "Filtering Formats".  You can also simply
              specify a field to match if the field is present, use  "!field"  to  check  if  the
              field is not present, and "&" to check multiple conditions.  Use a "" to escape "&"
              or quotes if needed.  If used multiple times, the filter matches if atleast one  of
              the   conditions   are   met.    E.g.    --match-filter   !is_live   --match-filter
              "like_count>?100 & description~='(?i)& dogs" matches only videos that are not  live
              OR  those that have a like count more than 100 (or the like field is not available)
              and also has a description that contains the phrase "cats & dogs" (caseless).   Use
              "--match-filter -" to interactively ask whether to download each video

              http/ftp downloads, and the  native  downloader  for  dash/m3u8  downloads  (Alias:
              --external-downloader)

       --downloader-args NAME:ARGS
              Give  these  arguments to the external downloader.  Specify the downloader name and

              delimited  list  of  NAME=VALUE.   The  "when"   argument   determines   when   the
              postprocessor is invoked.  It can be one of "pre_process" (after video extraction),
              "after_filter"  (after  video  passes  filter),  "video"  (after  --format;  before
              --print/--output),  "before_dl" (before each video download), "post_process" (after
              each video download; default), "after_move" (after moving video file to it's  final
              locations),  "after_video"  (after  downloading  and  processing  all  formats of a
              video), or "playlist" (at end of playlist).  This option can be used multiple times
              to add different postprocessors

   SponsorBlock Options:
       Make  chapter entries for, or remove various segments (sponsor, introductions, etc.)  from
       downloaded YouTube videos using the SponsorBlock API (https://sponsor.ajay.app)

       --sponsorblock-mark CATS
              SponsorBlock categories to create chapters for,  separated  by  commas.   Available
              categories  are  sponsor,  intro,  outro,  selfpromo, preview, filler, interaction,
              music_offtopic, poi_highlight, chapter, all and default (=all).  You can prefix the
              category  with  a  "-"  to  exclude it.  See [1] for description of the categories.
              E.g.               --sponsorblock-mark               all,-preview               [1]

              extractors

CONFIGURATION

       You  can  configure yt-dlp by placing any supported command line option to a configuration
       file.  The configuration is loaded from the following locations:

       1. Main Configuration:

           • The file given by --config-location

       2. Portable Configuration: (Recommended for portable installations)

           • If using a binary, yt-dlp.conf in the same directory as the binary

           • If running from source-code, yt-dlp.conf in the parent directory of yt_dlp

       3. Home Configuration:

           • yt-dlp.conf in the home path given by -P

           • If -P is not given, the current directory is searched

       4. User Configuration:

           • ${XDG_CONFIG_HOME}/yt-dlp.conf${XDG_CONFIG_HOME}/yt-dlp/config (recommended on Linux/macOS)

           • ${XDG_CONFIG_HOME}/yt-dlp/config.txt${APPDATA}/yt-dlp.conf${APPDATA}/yt-dlp/config (recommended on Windows)

           • ${APPDATA}/yt-dlp/config.txt~/yt-dlp.conf~/yt-dlp.conf.txt~/.yt-dlp/config~/.yt-dlp/config.txt See also: Notes about environment variables

       5. System Configuration:

           • /etc/yt-dlp.conf/etc/yt-dlp/config/etc/yt-dlp/config.txt

       E.g.  with the following configuration file yt-dlp will always extract the audio, not copy
       the mtime, use a proxy and save all videos under YouTube directory in your home directory:

              # Lines starting with # are comments

              # Always extract audio
              -x

              # Do not copy the mtime
              --no-mtime

              # Use this proxy
              --proxy 127.0.0.1:3128

              # Save all videos under YouTube directory in your home directory
              -o ~/YouTube/%(title)s.%(ext)s

       Note: Options in configuration file are just the same options aka switches used in regular
       command line calls; thus there must be no whitespace after - or --, e.g.   -o  or  --proxy
       but  not  -  o  or -- proxy.  They must also be quoted when necessary as-if it were a UNIX
       shell.

       You can use --ignore-config  if  you  want  to  disable  all  configuration  files  for  a
       particular  yt-dlp  run.   If  --ignore-config  is found inside any configuration file, no
       further configuration will be loaded.  For example, having  the  option  in  the  portable
       configuration   file   prevents   loading   of  home,  user,  and  system  configurations.
       Additionally, (for backward compatibility) if --ignore-config is found inside  the  system
       configuration file, the user configuration is not loaded.

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

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

   Authentication with .netrc file
       You may also want to configure automatic credentials storage for extractors  that  support
       authentication  (by  providing login and password with --username and --password) in order
       not to pass credentials as command line arguments on every yt-dlp  execution  and  prevent
       tracking  plain text passwords in the shell command history.  You can achieve this using a
       .netrc file (https://stackoverflow.com/tags/.netrc/info) on a  per-extractor  basis.   For
       that you will need to create a .netrc file in --netrc-location and restrict permissions to
       read/write by only you:

              touch ${HOME}/.netrc
              chmod a-rwx,u+rw ${HOME}/.netrc

       After that you can add credentials  for  an  extractor  in  the  following  format,  where
       extractor is the name of the extractor in lowercase:

              machine <extractor> login <username> password <password>

       E.g.

              machine youtube login myaccount@gmail.com password my_youtube_password
              machine twitch login my_twitch_account_name password my_twitch_password

       To activate authentication with the .netrc file you should pass --netrc to yt-dlp or place
       it in the configuration file.

       The default location of the .netrc file is ~ (see below).

   Notes about environment variables
       • Environment variables are  normally  specified  as  ${VARIABLE}/$VARIABLE  on  UNIX  and
         %VARIABLE% on Windows; but is always shown as ${VARIABLE} in this documentation

       • yt-dlp  also  allow  using  UNIX-style  variables on Windows for path-like options; e.g.
         --output, --config-location

       • If unset, ${XDG_CONFIG_HOME} defaults to ~/.config and ${XDG_CACHE_HOME} to ~/.cache

       • On   Windows,   ~   points   to   ${HOME}   if   present;    or,    ${USERPROFILE}    or
         ${HOMEDRIVE}${HOMEPATH} otherwise

       • On  Windows,  ${USERPROFILE}  generally points to C:\Users\<user name> and ${APPDATA} to
         ${USERPROFILE}\AppData\Roaming

OUTPUT TEMPLATE

       The -o option is used to indicate a template for the output file names while -P option  is
       used to specify the path each type of file should be saved to.

       The  simplest  usage  of -o is not to set any template arguments when downloading a single
       file, like in yt-dlp -o funny_video.flv "https://some/video" (hard-coding  file  extension
       like this is not recommended and could break some post-processing).

       It  may however also contain special sequences that will be replaced when downloading each
       video.  The special sequences may be  formatted  according  to  Python  string  formatting
       operations           (https://docs.python.org/3/library/stdtypes.html#printf-style-string-
       formatting), e.g.  %(NAME)s or %(NAME)05d.  To clarify, that is a percent symbol  followed
       by a name in parentheses, followed by formatting operations.

       The  field  names  themselves (the part inside the parenthesis) can also have some special
       formatting:

       1. Object traversal: The dictionaries and lists available in metadata can be traversed  by
          using  a dot . separator; e.g.  %(tags.0)s, %(subtitles.en.-1.ext)s.  You can do Python
          slicing with colon :; E.g.  %(id.3:7:-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

       2. 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

       3. 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

       4. Alternatives:  Alternate  fields  can  be  specified  separated   with   a   ,.    E.g.
          %(release_date>%Y,upload_date>%Y|Unknown)s

       5. Replacement: A replacement value can be specified using a & separator.  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.

       6. 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

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

       8. Unicode normalization: The format type U can be  used  for  NFC  Unicode  normalization
          (https://docs.python.org/3/library/unicodedata.html#unicodedata.normalize).         The
          alternate form flag (#) changes the normalization to NFD and the conversion flag +  can
          be used for NFKC/NFKD compatibility equivalence normalization.  E.g.  %(title)+.100U is
          NFKC

       To summarize, the general syntax for a field is:

              %(name[.keys][addition][>strf][,alternate][&replacement][|default])[flags][width][.precision][length]type

       Additionally, you can set different  output  templates  for  the  various  metadata  files
       separately from the general output template by specifying the type of file followed by the
       template separated by a colon  :.   The  different  file  types  supported  are  subtitle,
       thumbnail,   description,   annotation   (deprecated),   infojson,   link,   pl_thumbnail,
       pl_description,  pl_infojson,  chapter,  pl_video.   E.g.    -o   "%(title)s.%(ext)s"   -o
       "thumbnail:%(title)s\%(title)s.%(ext)s"  will put the thumbnails in a folder with the same
       name as the video.  If any of the templates is empty,  that  type  of  file  will  not  be
       written.  E.g.  --write-thumbnail -o "thumbnail:" will write thumbnails only for playlists
       and not for video.

       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.

       yt-dlp test video-BaW_jenozKc.mp4 file created in the current directory.

       Note:  Some  of  the  sequences  are not guaranteed to be present since they depend on the
       metadata obtained by a  particular  extractor.   Such  sequences  will  be  replaced  with
       placeholder value provided with --output-na-placeholder (NA by default).

       Tip: Look at the -j output to identify which fields are available for the particular URL

       For     numeric     sequences     you     can     use     numeric    related    formatting
       (https://docs.python.org/3/library/stdtypes.html#printf-style-string-formatting);     e.g.
       %(view_count)05d  will  result  in  a  string  with  view  count padded with zeros up to 5
       characters, like in 00042.

       Output   templates   can   also   contain   arbitrary   hierarchical   path,   e.g.     -o
       "%(playlist)s/%(playlist_index)s  -  %(title)s.%(ext)s"  which  will result in downloading
       each video in a directory corresponding to this path template.  Any missing directory will
       be automatically created for you.

       To use percent literals in an output template use %%.  To output to stdout use -o -.

       The current default template is %(title)s [%(id)s].%(ext)s.

       In  some  cases,  you don't want special characters such as 中, spaces, or &, such as when
       transferring the downloaded filename to a Windows system or the filename through an  8bit-
       unsafe channel.  In these cases, add the --restrict-filenames flag to get a shorter title.

              # Stream the video being downloaded to stdout
              $ yt-dlp -o - BaW_jenozKc

FORMAT SELECTION

       By  default,  yt-dlp  tries  to  download the best available quality if you don't pass any
       options.  This is generally equivalent to using -f bestvideo*+bestaudio/best.  However, if
       multiple  audiostreams is enabled (--audio-multistreams), the default format changes to -f
       bestvideo+bestaudio/best.  Similarly, if ffmpeg is unavailable, or if you  use  yt-dlp  to
       stream to stdout (-o -), the default becomes -f best/bestvideo+bestaudio.

       Deprecation  warning:  Latest versions of yt-dlp can stream multiple formats to the stdout
       simultaneously using ffmpeg.  So, in future versions, the default for this will be set  to
       -f  bv*+ba/b similar to normal downloads.  If you want to preserve the -f b/bv+ba setting,
       it is recommended to explicitly specify it in the configuration options.

       The general syntax for format selection is -f FORMAT (or --format FORMAT) where FORMAT  is
       a selector expression, i.e.  an expression that describes format or formats you would like
       to download.

       The simplest case is requesting a specific format; e.g.  with -f 22 you can  download  the
       format  with  format code equal to 22.  You can get the list of available format codes for
       particular video using --list-formats or -F.  Note that these format codes  are  extractor
       specific.

       You  can also use a file extension (currently 3gp, aac, flv, m4a, mp3, mp4, ogg, wav, webm
       are supported) to download the best quality format of a particular file  extension  served
       as  a  single  file,  e.g.   -f  webm  will download the best quality format with the webm
       extension served as a single file.

       You can use -f - to interactively provide the format selector for each video

       You can also use special names to select particular edge case formats:

       • all: Select all formats separately

       • mergeall: Select and merge all formats (Must be used with --audio-multistreams, --video-
         multistreams or both)

       • b*,  best*:  Select  the best quality format that contains either a video or an audio or
         both (ie; vcodec!=none or acodec!=none)

       • b, best: Select the best quality format that contains both video and audio.   Equivalent
         to best*[vcodec!=none][acodec!=none]bv,   bestvideo:   Select   the   best   quality   video-only   format.   Equivalent  to
         best*[acodec=none]bv*, bestvideo*: Select the best quality  format  that  contains  video.   It  may  also
         contain audio.  Equivalent to best*[vcodec!=none]ba,   bestaudio:   Select   the   best   quality   audio-only   format.   Equivalent  to
         best*[vcodec=none]ba*, bestaudio*: Select the best quality  format  that  contains  audio.   It  may  also
         contain  video.   Equivalent to best*[acodec!=none] (Do not use! (https://github.com/yt-
         dlp/yt-dlp/issues/979#issuecomment-919629354))

       • w*, worst*: Select the worst quality format that contains either a video or an audio

       • w, worst:  Select  the  worst  quality  format  that  contains  both  video  and  audio.
         Equivalent to worst*[vcodec!=none][acodec!=none]wv,   worstvideo:   Select   the   worst   quality  video-only  format.   Equivalent  to
         worst*[acodec=none]wv*, worstvideo*: Select the worst quality format that  contains  video.   It  may  also
         contain audio.  Equivalent to worst*[vcodec!=none]wa,   worstaudio:   Select   the   worst   quality  audio-only  format.   Equivalent  to
         worst*[vcodec=none]wa*, worstaudio*: Select the worst quality format that  contains  audio.   It  may  also
         contain video.  Equivalent to worst*[acodec!=none]

       For  example,  to  download the worst quality video-only format you can use -f worstvideo.
       It is however recommended not to use worst and related options.  When your format selector
       is  worst,  the format which is worst in all respects is selected.  Most of the time, what
       you actually want is the video with the smallest filesize instead.   So  it  is  generally
       better  to  use  -S  +size or more rigorously, -S +size,+br,+res,+fps instead of -f worst.
       See Sorting Formats for more details.

       You can select the n'th best format of a  type  by  using  best<type>.<n>.   For  example,
       best.2  will  select  the  2nd best combined format.  Similarly, bv*.3 will select the 3rd
       best format that contains a video stream.

       If you want to download multiple videos, and they don't have the same  formats  available,
       you can specify the order of preference using slashes.  Note that formats on the left hand
       side are preferred; e.g.  -f 22/17/18 will download format 22 if it's available, otherwise
       it will download format 17 if it's available, otherwise it will download format 18 if it's
       available, otherwise it will complain that no suitable formats are available for download.

       If you want to download several formats of the same video use a comma as a separator, e.g.
       -f  22,17,18 will download all these three formats, of course if they are available.  Or a
       more   sophisticated    example    combined    with    the    precedence    feature:    -f
       136/137/mp4/bestvideo,140/m4a/bestaudio.

       You  can  merge  the  video  and  audio  of  multiple  formats into a single file using -f
       <format1>+<format2>+... (requires ffmpeg installed);  e.g.   -f  bestvideo+bestaudio  will
       download the best video-only format, the best audio-only format and mux them together with
       ffmpeg.

       Deprecation warning: Since the below described behavior is complex and  counter-intuitive,
       this  will  be  removed  and multistreams will be enabled by default in the future.  A new
       operator will be instead added to limit formats to single audio/video

       Unless --video-multistreams is used, all formats with a video stream except the first  one
       are  ignored.   Similarly,  unless --audio-multistreams is used, all formats with an audio
       stream except the first one  are  ignored.   E.g.   -f  bestvideo+best+bestaudio  --video-
       multistreams  --audio-multistreams  will  download  and  merge  all  3 given formats.  The
       resulting  file  will  have   2   video   streams   and   2   audio   streams.    But   -f
       bestvideo+best+bestaudio  --no-video-multistreams  will  download and merge only bestvideo
       and bestaudio.  best is ignored since another format containing a video stream (bestvideo)
       has  already  been  selected.   The  order  of  the  formats  is  therefore important.  -f
       best+bestaudio --no-audio-multistreams will download only  best  while  -f  bestaudio+best
       --no-audio-multistreams will ignore best and download only bestaudio.

   Filtering Formats
       You  can  also  filter  the  video  formats  by  putting a condition in brackets, as in -f
       "best[height=720]" (or -f "[filesize>10M]").

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

       • filesize: The number of bytes, if known in advance

       • filesize_approx: An estimate for the number of bytes

       • width: Width of the video, if known

       • height: Height of the video, if known

       • aspect_ratio: Aspect ratio of the video, if known

       • tbr: Average bitrate of audio and video in KBit/s

       • abr: Average audio bitrate in KBit/s

       • vbr: Average video bitrate in KBit/s

       • asr: Audio sampling rate in Hertz

       • fps: Frame rate

       • audio_channels: The number of audio channels

       • stretched_ratio: width:height of the video's pixels, if not square

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

       • url: Video URL

       • ext: File extension

       • acodec: Name of the audio codec in use

       • vcodec: Name of the video codec in use

       • container: Name of the container format

       • protocol: The protocol that will be used for  the  actual  download,  lower-case  (http,
         https, rtsp, rtmp, rtmpe, mms, f4m, ism, http_dash_segments, m3u8, or m3u8_native)

       • language: Language code

       • dynamic_range: The dynamic range of the video

       • format_id: A short description of the format

       • format: A human-readable description of the format

       • format_note: Additional info about the format

       • resolution: Textual description of width and height

       Any  string  comparison  may  be  prefixed with negation ! in order to produce an opposite
       comparison, e.g.  !*= (does not contain).  The comparand of a string comparison  needs  to
       be  quoted with either double or single quotes if it contains spaces or special characters
       other than ._-.

       Note: None of the aforementioned meta fields are  guaranteed  to  be  present  since  this
       solely  depends  on  the  metadata  obtained  by  particular extractor, i.e.  the metadata
       offered by the website.  Any other field made available by the extractor can also be  used
       for filtering.

       Formats  for  which the value is not known are excluded unless you put a question mark (?)
       after the operator.  You can  combine  format  filters,  so  -f  "[height<=?720][tbr>500]"
       selects  up  to 720p videos (or videos where the height is not known) with a bitrate of at
       least 500 KBit/s.  You can also use the filters with all  to  download  all  formats  that
       satisfy the filter, e.g.  -f "all[vcodec=none]" selects all audio-only formats.

       Format  selectors can also be grouped using parentheses; e.g.  -f "(mp4,webm)[height<480]"
       will download the best pre-merged mp4 and webm formats with a height lower than 480.

   Sorting Formats
       You can change the criteria for being considered the best  by  using  -S  (--format-sort).
       The general format for this is --format-sort field1,field2....

       The available fields are:

       • hasvid: Gives priority to formats that have a video stream

       • hasaud: Gives priority to formats that have an audio stream

       • ie_pref: The format preference

       • lang: The language preference

       • quality: The quality of the format

       • source: The preference of the source

       • proto:   Protocol  used  for  download  (https/ftps  >  http/ftp  >  m3u8_native/m3u8  >
         http_dash_segments> websocket_frag > mms/rtsp > f4f/f4m)

       • vcodec: Video Codec (av01 > vp9.2 > vp9 > h265 > h264 > vp8 > h263 > theora > other)

       • acodec: Audio Codec (flac/alac > wav/aiff > opus > vorbis > aac > mp4a >  mp3  >  ac4  >
         eac3 > ac3 > dts > other)

       • codec: Equivalent to vcodec,acodecvext:  Video  Extension  (mp4  > mov > webm > flv > other).  If --prefer-free-formats is
         used, webm is preferred.

       • 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 > aacext: Equivalent to vext,aextfilesize: Exact filesize, if known in advance

       • fs_approx: Approximate filesize calculated from the manifests

       • size: Exact filesize if available, otherwise approximate filesize

       • height: Height of video

       • width: Width of video

       • res: Video resolution, calculated as the smallest dimension.

       • fps: Framerate of video

       • hdr: The dynamic range of the video (DV > HDR12 > HDR10+ > HDR10 > HLG > SDR)

       • channels: The number of audio channels

       • tbr: Total average bitrate in KBit/s

       • vbr: Average video bitrate in KBit/s

       • abr: Average audio bitrate in KBit/s

       • br: Equivalent to using tbr,vbr,abrasr: Audio sample rate in Hz

       Deprecation  warning: Many of these fields have (currently undocumented) aliases, that may
       be removed in a future version.  It is recommended to use only the documented field names.

       All fields, unless specified otherwise, are sorted in descending order.  To reverse  this,
       prefix  the  field  with  a  +.   E.g.   +res prefers format with the smallest resolution.
       Additionally, you can suffix a preferred value for the fields, separated  by  a  :.   E.g.
       res:720 prefers larger videos, but no larger than 720p and the smallest video if there are
       no videos less than 720p.  For codec and ext, you can provide two  preferred  values,  the
       first   for  video  and  the  second  for  audio.   E.g.   +codec:avc:m4a  (equivalent  to
       +vcodec:avc,+acodec:m4a) sets the video codec preference to h264 > h265 > vp9  >  vp9.2  >
       av01  > vp8 > h263 > theora and audio codec preference to mp4a > aac > vorbis > opus > mp3
       > ac3 > dts.  You can also make the sorting prefer the nearest values to the  provided  by
       using ~ as the delimiter.  E.g.  filesize~1G prefers the format with filesize closest to 1
       GiB.

       The fields hasvid and ie_pref are always given highest priority in  sorting,  irrespective
       of  the  user-defined  order.  This behaviour can be changed by using --format-sort-force.
       Apart       from       these,       the        default        order        used        is:
       lang,quality,res,fps,hdr:12,vcodec:vp9.2,channels,acodec,size,br,asr,proto,ext,hasaud,source,id.
       The extractors may override this default order, but they cannot override the user-provided
       order.

       Note  that  the  default  has  vcodec:vp9.2;  i.e.   av1 is not preferred.  Similarly, the
       default for hdr is hdr:12; i.e.  dolby vision is not preferred.  These  choices  are  made
       since  DV  and  AV1  formats  are not yet fully compatible with most devices.  This may be
       changed in the future as more devices  become  capable  of  smoothly  playing  back  these
       formats.

       If  your format selector is worst, the last item is selected after sorting.  This means it
       will select the format that is worst in all respects.  Most of the time, what you actually
       want is the video with the smallest filesize instead.  So it is generally better to use -f
       best -S +size,+br,+res,+fps.

       Tip: You can use the -v -F to see how the formats have been sorted (worst to best).

MODIFYING METADATA

       The metadata obtained by the extractors can be  modified  by  using  --parse-metadata  and
       --replace-in-metadata

       --replace-in-metadata  FIELDS  REGEX REPLACE is used to replace text in any metadata field
       using  python   regular   expression   (https://docs.python.org/3/library/re.html#regular-
       expression-syntax).                                                         Backreferences
       (https://docs.python.org/3/library/re.html?highlight=backreferences#re.sub) can be used in
       the replace string for advanced use.

       The general syntax of --parse-metadata FROM:TO is to give the name of a field or an output
       template 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  (only  %(field)s  formatting is supported) can be used for TO.  The
       option can be used multiple times to parse and modify various fields.

       Note that these options preserve their relative order, allowing replacements to be made in
       parsed  fields  and  viceversa.   Also,  any  field thus created can be used in the output
       template and will also affect the media file's metadata added when using --embed-metadata.

       This option also has a few special uses:

       • You can download an additional URL based on the metadata  of  the  currently  downloaded
         video.   To do this, set the field additional_urls to the URL that you want to download.
         E.g.   --parse-metadata   "description:(?P<additional_urls>https?://www\.vimeo\.com/\d+)
         will download the first vimeo video found in the description

       • You can use this to change the metadata that is embedded in the media file.  To do this,
         set the value of the corresponding field with a meta_ prefix.  For  example,  any  value
         you  set  to meta_description field will be added to the description field in the file -
         you can use this to set  a  different  "description"  and  "synopsis".   To  modify  the
         metadata  of  individual  streams,  use the meta<n>_ prefix (e.g.  meta1_language).  Any
         value set to the meta_ field will overwrite all default values.

       Note: Metadata modification happens before format  selection,  post-extraction  and  other
       post-processing  operations.   Some  fields  may  be  added or changed during these steps,
       overriding your changes.

       For reference, these are the fields yt-dlp adds by default to the file metadata:

       Metadata fields             From
       ──────────────────────────────────────────────────────────────────────────
       title                       track or title

       purl, comment               webpage_url
       track                       track_number
       artist                      artist, creator, uploader or uploader_id

       Note: The file format may not support some of these fields

   Modifying metadata examples
              # Interpret the title as "Artist - Title"
              $ yt-dlp --parse-metadata "title:%(artist)s - %(title)s"

              # Regex example
              $ yt-dlp --parse-metadata "description:Artist - (?P<artist>.+)"

              # Set title as "Series name S01E05"
              $ yt-dlp --parse-metadata "%(series)s S%(season_number)02dE%(episode_number)02d:%(title)s"

              # Prioritize uploader as the "artist" field in video metadata
              $ yt-dlp --parse-metadata "%(uploader|)s:%(meta_artist)s" --embed-metadata

              # Set "comment" field in video metadata using description instead of webpage_url,
              # handling multiple lines correctly
              $ yt-dlp --parse-metadata "description:(?s)(?P<meta_comment>.+)" --embed-metadata

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

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

              # Replace all spaces and "_" in title and uploader with a `-`
              $ yt-dlp --replace-in-metadata "title,uploader" "[ _]" "-"

EXTRACTOR ARGUMENTS

       Some extractors accept additional arguments which can  be  passed  using  --extractor-args
       KEY:ARGS.   ARGS is a ; (semicolon) separated string of ARG=VAL1,VAL2.  E.g.  --extractor-
       args    "youtube:player-client=android_embedded,web;include_live_dash"    --extractor-args
       "funimation:version=uncut"

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

       The following extractors use this feature:

   youtubelang: Prefer translated metadata (title, description etc) of this language  code  (case-
         sensitive).   By  default,  the  video  primary  language  metadata is preferred, with a
         fallback   to   en   translated.     See    youtube.py    (https://github.com/yt-dlp/yt-
         dlp/blob/c26f9b991a0681fd3ea548d535919cec1fbbd430/yt_dlp/extractor/youtube.py#L381-L390)
         for list of supported content language codes

       • skip: One or more of hls, dash  or  translated_subs  to  skip  extraction  of  the  m3u8
         manifests,  dash  manifests and auto-translated subtitles (https://github.com/yt-dlp/yt-
         dlp/issues/4090#issuecomment-1158102032) respectively

       • player_client: Clients to extract video data from.  The main clients  are  web,  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.

       • 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

         • 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

       • include_incomplete_formats:  Extract  formats that cannot be downloaded completely (live
         dash and post-live m3u8)

       • innertube_host:   Innertube   API   host   to   use   for   all   API   requests;   e.g.
         studio.youtube.com,  youtubei.googleapis.com.   Note  that  cookies  exported  from  one
         subdomain will not work on others

       • innertube_key: Innertube API key to use for all API requests

   youtubetab (YouTube playlists, channels, feeds, etc.)skip: One or more of webpage (skip  initial  webpage  download),  authcheck  (allow  the
         download  of  playlists  requiring authentication when no initial webpage is downloaded.
         This may cause unwanted behavior, see #1122 (https://github.com/yt-dlp/yt-dlp/pull/1122)
         for more details)

       • approximate_date:  Extract approximate upload_date and timestamp in flat-playlist.  This
         may cause date-based filters to be slightly off

   crunchyrollbeta (Crunchyroll)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_v2hardsub: Preference order for which hardsub versions to extract, or all (default: None =
         no hardsubs), e.g.  crunchyrollbeta:hardsub=en-US,None

   vikichannelvideo_types: Types of videos to download - one  or  more  of  episodes,  movies,  clips,
         trailers

   niconicosegment_duration:  Segment duration in milliseconds for HLS-DMC formats.  Use it at your

   tiktokapi_hostname: Hostname to use for mobile API requests, e.g.  api-h2.tiktokv.comapp_version: App  version  to  call  mobile  APIs  with  -  should  be  set  along  with
         manifest_app_version, e.g.  20.2.1manifest_app_version: Numeric app version to call mobile APIs with, e.g.  221

   rokfinchanneltab: Which tab to download - one of new, top, videos, podcasts, streams, stacks

   twitterforce_graphql: Force usage of the GraphQL API.  By default it will only be used if login
         cookies are provided

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

INSTALLATION

       You  can  install  yt-dlp using the binaries, 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

   UPDATE
       You can use yt-dlp -U to update if you are using the release binaries

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

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

       There  are currently two release channels for binaries, stable and nightly.  stable is the
       default channel, and many of its changes have been tested by users of the nightly channel.
       The nightly channel has releases built after each push to the master branch, and will have
       the most recent fixes and additions, but also have more risk  of  regressions.   They  are
       available in their own repo (https://github.com/yt-dlp/yt-dlp-nightly-builds/releases).

       When  using  --update/-U,  a release binary will only update to its current channel.  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.

       Example  usage:  *  yt-dlp --update-to nightly change to nightly channel and update to its
       latest release * yt-dlp --update-to  stable@2023.02.17  upgrade/downgrade  to  release  to
       stable  channel  tag  2023.02.17  * yt-dlp --update-to 2023.01.06 upgrade/downgrade to tag
       2023.01.06 if it exists on the current channel

       Note: The manpages, shell completion files etc.  are available inside the  source  tarball
       (https://github.com/yt-dlp/yt-dlp/releases/latest/download/yt-dlp.tar.gz)

   DEPENDENCIES
       Python versions 3.7+ (CPython and PyPy) are supported.  Other versions and implementations
       may or may not work correctly.

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

   Strongly recommendedffmpeg and ffprobe (https://www.ffmpeg.org) - Required for merging  separate  video  and
         audio  files as well as for various post-processing tasks.  License depends on the build
         (https://www.ffmpeg.org/legal.html)

         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

         Important:  What  you  need  is  ffmpeg  binary, NOT the python package of the same name

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

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

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

   COMPILE
   Standalone PyInstaller Builds
       To build the standalone executable, you must have Python and pyinstaller (plus any of  yt-
       dlp's  optional  dependencies  if  needed).   Once you have all the necessary dependencies
       installed, simply run pyinst.py.  The executable will be built for the  same  architecture
       (x86/ARM, 32/64 bit) as the Python used.

              python3 -m pip install -U pyinstaller -r requirements.txt
              python3 devscripts/make_lazy_extractors.py
              python3 pyinst.py

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

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

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

       Important:  Running  pyinstaller  directly  without  using  pyinst.py  is  not  officially
       supported.  This may or may not work correctly.

   Platform-independent Binary (UNIX)
       You will need the build tools python (3.7+), zip, make (GNU), pandoc* and pytest*.

       After installing these, simply run make.

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

   Standalone Py2Exe Builds (Windows)
       While  we  provide  the  option  to  build  with  py2exe  (https://www.py2exe.org),  it is
       recommended to build using PyInstaller instead since  the  py2exe  builds  cannot  contain
       pycryptodomex/certifi and needs VC++14 on the target computer to run.

       If  you  wish  to build it anyway, install Python and py2exe, and then simply run setup.py
       py2exe

              py -m pip install -U py2exe -r requirements.txt
              py devscripts/make_lazy_extractors.py
              py setup.py py2exe

   Forking the project
       If you fork the project on GitHub, you can run your fork's build workflow to automatically

       workflow or enable the nightly workflow to create full (pre-)releases.

PLUGINS

       Note that all plugins are imported even if not invoked,  and  that  there  are  no  checks
       performed on plugin code.  Use plugins at your own risk and only if you trust the code!

       Plugins  can be of <type>s extractor or postprocessor.  - Extractor plugins do not need to
       be enabled from the CLI and are automatically invoked when the input URL is  suitable  for
       it.   -  Extractor plugins take priority over builtin extractors.  - Postprocessor plugins
       can be invoked using --use-postprocessor NAME.

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

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

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

       yt-dlp  looks for these yt_dlp_plugins namespace folders in many locations (see below) and
       loads in plugins from all of them.

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

   Installing Plugins
       Plugins can be installed using various methods and locations.

       1. Configuration directories:  Plugin  packages  (containing  a  yt_dlp_plugins  namespace
          folder) can be dropped into the following standard configuration locations:

           • User Plugins${XDG_CONFIG_HOME}/yt-dlp/plugins/<package  name>/yt_dlp_plugins/  (recommended on
               Linux/macOS)

             • ${XDG_CONFIG_HOME}/yt-dlp-plugins/<package name>/yt_dlp_plugins/${APPDATA}/yt-dlp/plugins/<package name>/yt_dlp_plugins/ (recommended on Windows)

             • ${APPDATA}/yt-dlp-plugins/<package name>/yt_dlp_plugins/~/.yt-dlp/plugins/<package name>/yt_dlp_plugins/~/yt-dlp-plugins/<package name>/yt_dlp_plugins/System Plugins/etc/yt-dlp/plugins/<package name>/yt_dlp_plugins//etc/yt-dlp-plugins/<package name>/yt_dlp_plugins/

       2. Executable location: Plugin packages can similarly be  installed  in  a  yt-dlp-plugins
          directory under the executable location:

           • Binary:      where     <root-dir>/yt-dlp.exe,     <root-dir>/yt-dlp-plugins/<package
             name>/yt_dlp_plugins/

           • Source:  where   <root-dir>/yt_dlp/__main__.py,   <root-dir>/yt-dlp-plugins/<package
             name>/yt_dlp_plugins/

       3. pip and other locations in PYTHONPATH

           • Plugin  packages  can be installed and managed using pip.  See yt-dlp-sample-plugins
             (https://github.com/yt-dlp/yt-dlp-sample-plugins) for an example.

             • Note: plugin files between plugin packages installed with  pip  must  have  unique
               filenames.

           • Any path in PYTHONPATH is searched in for the yt_dlp_plugins namespace folder.

             • Note: This does not apply for Pyinstaller/py2exe builds.

       .zip,  .egg  and  .whl archives containing a yt_dlp_plugins namespace folder in their root
       are   also   supported   as   plugin    packages.     *    e.g.     ${XDG_CONFIG_HOME}/yt-
       dlp/plugins/mypluginpkg.zip            where            mypluginpkg.zip           contains
       yt_dlp_plugins/<type>/myplugin.py

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

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

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

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

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

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

EMBEDDING YT-DLP

       yt-dlp makes the best effort to be  a  good  command-line  program,  and  thus  should  be
       callable from any programming language.

       Your  program  should  avoid  parsing  the  normal  stdout since they may change in future
       versions.  Instead they should use  options  such  as  -J,  --print,  --progress-template,
       --exec etc to create console output that you can reliably reproduce and parse.

       From a Python program, you can embed yt-dlp in a more powerful fashion, like this:

              from yt_dlp import YoutubeDL

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

       Most  likely, you'll want to use various options.  For a list of options available, have a
       look at yt_dlp/YoutubeDL.py.

       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

   Embedding examples
   Extracting information
              import json

NEW FEATURES

       • 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)

       • SponsorBlock  Integration:  You  can  mark/remove  sponsor sections in YouTube videos by
         utilizing the SponsorBlock (https://sponsor.ajay.app) API

       • Format Sorting: The default format sorting options have  been  changed  so  that  higher
         resolution  and  better  codecs  will  be  now  preferred instead of simply using larger
         bitrate.  Furthermore, you can now specify the sort order using  -S.   This  allows  for
         much easier format selection than what is possible by simply using --format (examples)

       • Merged  with  animelover1984/youtube-dl:  You  get most of the features and improvements
         from animelover1984/youtube-dl (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.

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

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

       • yt-dlp supports only Python 3.7+, and may remove  support  for  more  versions  as  they
         become  EOL (https://devguide.python.org/versions/#python-release-cycle); while youtube-
         dl  still  supports   Python   2.6+   and   3.2+   (https://github.com/ytdl-org/youtube-
         dl/issues/30568#issue-1118238743)

       • The  options  --auto-number  (-A), --title (-t) and --literal (-l), no longer work.  See
         removed options for details

       • avconv is not supported as an alternative to ffmpeg

       • yt-dlp  stores  config  files  in  slightly  different  locations  to  youtube-dl.   See
         CONFIGURATION for a list of correct locations

       • The  default output template is %(title)s [%(id)s].%(ext)s.  There is no real reason for
         this change.  This was changed before yt-dlp was ever made public and now there  are  no
         plans  to  change  it  back to %(title)s-%(id)s.%(ext)s.  Instead, you may use --compat-
         options filename

       • The default format sorting is different from youtube-dl and  prefers  higher  resolution
         and  better codecs rather than higher bitrates.  You can use the --format-sort option to
         change this to any order you prefer, or use --compat-options format-sort to use youtube-
         dl's sorting order

       • The  default  format  selector is bv*+ba/b.  This means that if a combined video + audio
         format that is better than the best video-only format  is  found,  the  former  will  be
         preferred.  Use -f bv+ba/b or --compat-options format-spec to revert this

       • Unlike  youtube-dlc, yt-dlp does not allow merging multiple audio/video streams into one
         file by default (since this conflicts with the use  of  -f  bv*+ba).   If  needed,  this
         feature  must  be  enabled using --audio-multistreams and --video-multistreams.  You can
         also use --compat-options multistreams to enable both

       • --no-abort-on-error is enabled by default.   Use  --abort-on-error  or  --compat-options
         abort-on-error to abort on errors instead

       • When  writing  metadata  files  such  as  thumbnails,  description or infojson, the same
         information (if available) is also  written  for  playlists.   Use  --no-write-playlist-
         metafiles or --compat-options no-playlist-metafiles to not write these files

       • --add-metadata  attaches  the  infojson to mkv files in addition to writing the metadata
         when used with --write-info-json.   Use  --no-embed-info-json  or  --compat-options  no-
         attach-info-json to revert this

       • Some  metadata  are embedded into different fields when using --add-metadata as compared
         to youtube-dl.  Most notably,  comment  field  contains  the  webpage_url  and  synopsis
         contains the description.  You can use --parse-metadata to modify this to your liking or
         use --compat-options embed-metadata to revert this

       • playlist_index behaves differently when used with options  like  --playlist-reverse  and
         --playlist-items.   See  #302 (https://github.com/yt-dlp/yt-dlp/issues/302) for details.
         You can use --compat-options playlist-index if you want to keep the earlier behavior

       • The output of -F is listed in a new format.  Use --compat-options list-formats to revert
         this

       • Live  chats  (if available) are considered as subtitles.  Use --sub-langs all,-live_chat
         to download all subtitles except live chat.  You can also use --compat-options  no-live-
         chat to prevent any live chat/danmaku from downloading

       • YouTube  channel  URLs download all uploads of the channel.  To download only the videos
         in a specific tab, pass the tab's URL.  If the channel does not show the requested  tab,
         an  error  will  be raised.  Also, /live URLs raise an error if there are no live videos
         instead of silently downloading the entire channel.  You may  use  --compat-options  no-
         youtube-channel-redirect to revert all these redirections

       • Unavailable  videos  are  also  listed  for YouTube playlists.  Use --compat-options no-
         youtube-unavailable-videos to remove this

       • The   upload   dates   extracted   from   YouTube   are   in    UTC    when    available
         (https://github.com/yt-dlp/yt-
         dlp/blob/89e4d86171c7b7c997c77d4714542e0383bf0db0/yt_dlp/extractor/youtube.py#L3898-L3900).
         Use  --compat-options  no-youtube-prefer-utc-upload-date  to  prefer  the non-UTC upload
         date.

       • If ffmpeg is used as the downloader, the downloading and merging of formats happen in  a
         single step when possible.  Use --compat-options no-direct-merge to revert this

       • Thumbnail  embedding  in  mp4  is  done  with mutagen if possible.  Use --compat-options
         embed-thumbnail-atomicparsley to force the use of AtomicParsley instead

       • Some 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

       • When  --embed-subs and --write-subs are used together, the subtitles are written to disk
         and also embedded in the media file.  You can use just --embed-subs to  embed  the  subs
         and  automatically delete the separate file.  See #630 (comment) (https://github.com/yt-
         dlp/yt-dlp/issues/630#issuecomment-893659460) for more info.  --compat-options  no-keep-
         subs can be used to revert this

       • certifi will be used for SSL root certificates, if installed.  If you want to use system
         certificates (e.g.  self-signed), use --compat-options no-certifi

       • yt-dlp's sanitization of invalid characters in filenames is  different/smarter  than  in
         youtube-dl.   You  can  use --compat-options filename-sanitization to revert to youtube-
         dl's behavior

       • yt-dlp tries to parse the external downloader outputs into the standard progress  output
         if  possible  (Currently  implemented: [STRIKEOUT: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

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

       • --compat-options all: Use all compat options (Do NOT use)

       • --compat-options youtube-dl: Same as --compat-options all,-multistreams--compat-options  youtube-dlc:  Same  as --compat-options all,-no-live-chat,-no-youtube-
         channel-redirect--compat-options    2021:    Same    as    --compat-options    2022,no-certifi,filename-
         sanitization,no-youtube-prefer-utc-upload-date--compat-options  2022:  Same  as --compat-options no-external-downloader-progress.  Use
         this to enable all future compat options

DEPRECATED OPTIONS

       These are all the deprecated options and the  current  alternative  to  achieve  the  same
       effect

   Almost redundant options
       While  these  options  are  almost  the  same  as  their  new counterparts, there are some
       differences that prevents them being redundant

              -j, --dump-json                  --print "%()j"
              -F, --list-formats               --print formats_table
              --list-thumbnails                --print thumbnails_table --print playlist:thumbnails_table
              --list-subs                      --print automatic_captions_table --print subtitles_table

   Redundant options
       While these options are redundant, they are still expected to be used due to their ease of
       use

              --get-description                --print description
              --get-duration                   --print duration_string
              --get-filename                   --print filename
              --get-format                     --print format
              --get-id                         --print id
              --get-thumbnail                  --print thumbnail
              -e, --get-title                  --print title
              -g, --get-url                    --print urls
              --match-title REGEX              --match-filter "title ~= (?i)REGEX"
              --reject-title REGEX             --match-filter "title !~= (?i)REGEX"
              --min-views COUNT                --match-filter "view_count >=? COUNT"
              --max-views COUNT                --match-filter "view_count <=? COUNT"
              --break-on-reject                Use --break-match-filter
              --user-agent UA                  --add-header "User-Agent:UA"
              --referer URL                    --add-header "Referer:URL"
              --playlist-start NUMBER          -I NUMBER:
              --playlist-end NUMBER            -I :NUMBER
              --playlist-reverse               -I ::-1
              --no-playlist-reverse            Default

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

              --force-generic-extractor        --ies generic,default
              --exec-before-download CMD       --exec "before_dl:CMD"

              --autonumber-size NUMBER         Use string formatting, e.g. %(autonumber)03d
              --autonumber-start NUMBER        Use internal field formatting like %(autonumber+NUMBER)s
              --id                             -o "%(id)s.%(ext)s"
