NAME

       youtube-dl - download videos from youtube.com or other video platforms

SYNOPSIS

       youtube-dl [OPTIONS] URL [URL...]

DESCRIPTION

       youtube-dl  is  a small command-line program to download videos from YouTube.com and a few
       more sites.  It requires the Python interpreter, version 2.6, 2.7, or 3.2+, and it is  not
       platform  specific.   It  should  work on your Unix box, on Windows or on Mac OS X.  It is
       released to the public domain, which means you can modify it, redistribute it  or  use  it
       however you like.

OPTIONS

       -h, --help
              Print this help text and exit

       --version
              Print program version and exit

       -U, --update
              Update  this  program  to  latest  version.   Make  sure  that  you have sufficient
              permissions (run with sudo if needed)

       -i, --ignore-errors
              Continue on download errors, for example to skip unavailable videos in a playlist

       --abort-on-error
              Abort downloading of further videos (in the playlist or the  command  line)  if  an
              error occurs

       --dump-user-agent
              Display the current browser identification

       --list-extractors
              List all supported extractors

       --extractor-descriptions
              Output descriptions of all supported extractors

       --force-generic-extractor
              Force extraction to use the generic extractor

       --default-search PREFIX
              Use  this  prefix  for  unqualified  URLs.   For example "gvsearch2:" downloads two
              videos from google videos for youtube-dl "large apple".  Use the  value  "auto"  to
              let  youtube-dl  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
              Do  not read configuration files.  When given in the global configuration file /etc
              /youtube-dl.conf:  Do  not  read  the  user  configuration  in   ~/.config/youtube-

              Example: --exec 'adb push {} /sdcard/Music/ && rm {}'

       --convert-subs FORMAT
              Convert the subtitles to other format (currently supported: srt|ass|vtt)

CONFIGURATION

       You  can  configure  youtube-dl  by  placing  any  supported  command  line  option  to  a
       configuration  file.   On  Linux,  the  system  wide  configuration  file  is  located  at
       /etc/youtube-dl.conf  and the user wide configuration file at ~/.config/youtube-dl/config.
       On Windows, the user wide configuration file locations are %APPDATA%\youtube-dl\config.txt
       or  C:\Users\<user name>\youtube-dl.conf.   For  example, with the following configuration
       file youtube-dl will always extract the audio, not copy the mtime and use a proxy:

              --extract-audio
              --no-mtime
              --proxy 127.0.0.1:3128

       You can use --ignore-config if you want to disable the configuration file for a particular
       youtube-dl run.

   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 youtube-dl execution and
       prevent tracking plain text passwords in the shell command history.  You can achieve  this
       using  a  .netrc  file (http://stackoverflow.com/tags/.netrc/info) on per extractor basis.
       For that you will need to create a.netrc file in your $HOME and  restrict  permissions  to
       read/write by you only:

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

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

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

       For example:

              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  youtube-dl  or
       place it in the configuration file (#configuration).

       On Windows you may also need to setup the %HOME% environment variable manually.

OUTPUT TEMPLATE

       The  -o  option  allows users to indicate a template for the output file names.  The basic
       usage is not to set any template  arguments  when  downloading  a  single  file,  like  in
       youtube-dl -o funny_video.flv "http://some/video".    However,   it  may  contain  special
       sequences that will be replaced when downloading each video.  The special  sequences  have
       the  format  %(NAME)s.   To  clarify,  that  is  a  percent  symbol  followed by a name in
       parentheses, followed by a lowercase S.  Allowed names are:

       · id: Video identifier

       · title: Video title

       · url: Video URL

       · ext: Video filename extension

       · alt_title: A secondary title of the video

       · view_count: How many users have watched the video on the platform

       · like_count: Number of positive ratings of the video

       · dislike_count: Number of negative ratings of the video

       · repost_count: Number of reposts of the video

       · average_rating: Average rating give by users, the scale used depends on the webpage

       · comment_count: Number of comments on the video

       · age_limit: Age restriction for the video (years)

       · format: A human-readable description of the format

       · format_id: Format code specified by --format

       · format_note: Additional info about the format

       · width: Width of the video

       · height: Height of the video

       · resolution: Textual description of width and height

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

       · abr: Average audio bitrate in KBit/s

       · acodec: Name of the audio codec in use

       · asr: Audio sampling rate in Hertz

       · vbr: Average video bitrate in KBit/s

       · fps: Frame rate

       · vcodec: Name of the video codec in use

       · container: Name of the container format

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

       · filesize_approx: An estimate for the number of bytes

       · protocol: The protocol that will be used for the actual download

       · extractor: Name of the extractor

       · extractor_key: Key name of the extractor

       · epoch: Unix epoch when creating the file

       · autonumber: Five-digit number that will be increased with  each  download,  starting  at
         zero

       · playlist: Name or id of the playlist that contains the video

       · playlist_index:  Index  of the video in the playlist padded with leading zeros according
         to the total length of the playlist

       Available for the video that belongs to some logical chapter or section: -  chapter:  Name
       or  title  of the chapter the video belongs to - chapter_number: Number of the chapter the
       video belongs to - chapter_id: Id of the chapter the video belongs to

       Available for the video that is an episode of some series or programme: - series: Title of
       the  series  or  programme  the video episode belongs to - season: Title of the season the
       video episode belongs to - season_number: Number of the season the video  episode  belongs
       to  -  season_id:  Id  of  the season the video episode belongs to - episode: Title of the
       video episode - episode_number: Number of the video episode within a season -  episode_id:
       Id of the video episode

       Each  aforementioned  sequence  when referenced in output template will be replaced by the
       actual value corresponding to the sequence name.  Note that some of the sequences are  not
       guaranteed  to  be  present  since  they  depend  on  the  metadata obtained by particular
       extractor, such sequences will be replaced with NA.

       For example for -o %(title)s-%(id)s.%(ext)s and mp4 video with title youtube-dl test video
       and  id  BaW_jenozKcj  this  will  result in a youtube-dl test video-BaW_jenozKcj.mp4 file
       created in the current directory.

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

       To specify percent literal in 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:

       Examples (note on Windows you may need to use double quotes instead of single):

              $ youtube-dl --get-filename -o '%(title)s.%(ext)s' BaW_jenozKc
              youtube-dl test video ''_ä↭𝕐.mp4    # All kinds of weird characters

              $ youtube-dl --get-filename -o '%(title)s.%(ext)s' BaW_jenozKc --restrict-filenames
              youtube-dl_test_video_.mp4          # A simple file name

              # Download YouTube playlist videos in separate directory indexed by video order in a playlist
              $ youtube-dl -o '%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s' https://www.youtube.com/playlist?list=PLwiyx1dc3P2JR9N8gQaQN_BCvlSlap7re

              # Download Udemy course keeping each chapter in separate directory under MyVideos directory in your home
              $ youtube-dl -u user -p password -o '~/MyVideos/%(playlist)s/%(chapter_number)s - %(chapter)s/%(title)s.%(ext)s' https://www.udemy.com/java-tutorial/

              # Download entire series season keeping each series and each season in separate directory under C:/MyVideos
              $ youtube-dl -o "C:/MyVideos/%(series)s/%(season_number)s - %(season)s/%(episode_number)s - %(episode)s.%(ext)s" http://videomore.ru/kino_v_detalayah/5_sezon/367617

              # Stream the video being downloaded to stdout
              $ youtube-dl -o - BaW_jenozKc

FORMAT SELECTION

       By default youtube-dl tries to download the best available quality, i.e.  if you want  the
       best  quality you don't need to pass any special options, youtube-dl will guess it for you
       by default.

       But sometimes you may want to download in a different format, for example when you are  on
       a  slow  or  intermittent  connection.   The key mechanism for achieving this is so called
       format selection based on which you can explicitly specify desired format, select  formats
       based on some criterion or criteria, setup precedence and much more.

       The  general  syntax  for  format  selection is --format FORMAT or shorter -f 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, for example 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 best quality format of particular file extension served as a
       single file, e.g.  -f webm will download best quality format with webm extension served as
       a single file.

       You  can also use special names to select particular edge case format: - best: Select best
       quality format represented by single file with video  and  audio  -  worst:  Select  worst
       quality  format  represented  by single file with video and audio - bestvideo: Select best
       quality video only format (e.g.  DASH video), may not be available  -  worstvideo:  Select
       worst  quality  video  only  format, may not be available - bestaudio: Select best quality
       audio only format, may not be available - worstaudio:  Select  worst  quality  audio  only
       format, may not be available

       For example, to download worst quality video only format you can use -f worstvideo.

       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   slash   is
       left-associative,  i.e.   formats  on  the  left  hand  side  are  preferred,  for example
       -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 comma as a  separator,  e.g.
       -f 22,17,18  will  download  all these three formats, of course if they are available.  Or
       more      sophisticated      example      combined      with      precedence       feature
       -f 136/137/mp4/bestvideo,140/m4a/bestaudio.

       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 - width: Width of
       the video, if known - height: Height 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

       Also filtering work for comparisons = (equals), != (not  equals),  ^=  (begins  with),  $=
       (ends  with),  *=  (contains)  and  following  string meta fields: - 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, m3u8, or m3u8_native

       Note that 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 video hoster.

       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   merge   the  video  and  audio  of  two  formats  into  a  single  file  using
       -f <video-format>+<audio-format>  (requires  ffmpeg  or  avconv  installed),  for  example
       -f bestvideo+bestaudio  will  download  best video only format, best audio only format and
       mux them together with ffmpeg/avconv.

       Format selectors can also be grouped  using  parentheses,  for  example  if  you  want  to
       download  the  best  mp4  and  webm  formats  with  a  height  lower  than 480 you can use
       -f '(mp4,webm)[height<480]'.

       Since   the   end   of   April   2015   and    version    2015.04.26    youtube-dl    uses
       -f bestvideo+bestaudio/best  as default format selection (see #5447, #5456).  If ffmpeg or
       avconv are installed this results in downloading bestvideo and  bestaudio  separately  and
       muxing  them  together  into  a  single  file  giving  the best overall quality available.
       Otherwise it falls back to best and results in  downloading  the  best  available  quality
       served  as  a  single  file.   best is also needed for videos that don't come from YouTube
       because they don't provide the audio and video in two different files.   If  you  want  to
       only  download  some DASH formats (for example if you are not interested in getting videos
       with      a      resolution      higher      than      1080p),      you      can       add
       -f bestvideo[height<=?1080]+bestaudio/best  to  your configuration file.  Note that if you
       use youtube-dl to stream to stdout (and most likely to pipe it to your media player then),
       i.e.  you explicitly specify output template as -o -, youtube-dl still uses -f best format
       selection in order to start content delivery immediately to your player and  not  to  wait
       until bestvideo and bestaudio are downloaded and muxed.

       If  you  want  to  preserve  the  old  format  selection  behavior  (prior  to  youtube-dl
       2015.04.26), i.e.  you want to download the best  available  quality  media  served  as  a
       single  file, you should explicitly specify your choice with -f best.  You may want to add
       it to the configuration file (#configuration) in order not to type it every time  you  run
       youtube-dl.

       Examples (note on Windows you may need to use double quotes instead of single):

              # Download best mp4 format available or any other best if no mp4 available
              $ youtube-dl -f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best'

              # Download best format available but not better that 480p
              $ youtube-dl -f 'bestvideo[height<=480]+bestaudio/best[height<=480]'

              # Download best video only format but no bigger that 50 MB
              $ youtube-dl -f 'best[filesize<50M]'

              # Download best format available via direct link over HTTP/HTTPS protocol
              $ youtube-dl -f '(bestvideo+bestaudio/best)[protocol^=http]'

VIDEO SELECTION

       Videos  can  be  filtered  by  their upload date using the options --date, --datebefore or
       --dateafter.  They accept dates in two formats:

       · Absolute dates: Dates in the format YYYYMMDD.

       · Relative dates: Dates in the format (now|today)[+-][0-9](day|week|month|year)(s)?

       Examples:

              # Download only the videos uploaded in the last 6 months
              $ youtube-dl --dateafter now-6months

              # Download only the videos uploaded on January 1, 1970
              $ youtube-dl --date 19700101

              $ # Download only the videos uploaded in the 200x decade
              $ youtube-dl --dateafter 20000101 --datebefore 20091231

FAQ

   How do I update youtube-dl?
       If you've followed our  manual  installation  instructions  (http://rg3.github.io/youtube-
       dl/download.html), you can simply run youtube-dl -U (or, on Linux, sudo youtube-dl -U).

       If you have used pip, a simple sudo pip install -U youtube-dl is sufficient to update.

       If  you  have  installed  youtube-dl  using a package manager like apt-get or yum, use the
       standard system update mechanism to update.  Note that  distribution  packages  are  often
       outdated.  As a rule of thumb, youtube-dl releases at least once a month, and often weekly
       or even  daily.   Simply  go  to  http://yt-dl.org/  to  find  out  the  current  version.
       Unfortunately,  there  is  nothing  we  youtube-dl  developers can do if your distribution
       serves a really outdated version.  You can (and should) complain to your  distribution  in
       their bugtracker or support forum.

       As a last resort, you can also uninstall the version installed by your package manager and
       follow our manual installation instructions.  For that, remove the distribution's package,
       with a line like

              sudo apt-get remove -y youtube-dl

       Afterwards,      simply      follow      our      manual     installation     instructions
       (http://rg3.github.io/youtube-dl/download.html):

              sudo wget https://yt-dl.org/latest/youtube-dl -O /usr/local/bin/youtube-dl
              sudo chmod a+x /usr/local/bin/youtube-dl
              hash -r

       Again, from then on you'll be able to update with sudo youtube-dl -U.

   I'm getting an error
       Unable to extract OpenGraph title on YouTube playlists

       YouTube changed their playlist format in March 2014 and later on, so you'll need at  least
       youtube-dl 2014.07.25 to download all YouTube videos.

       If  you  have  installed  youtube-dl  with  a package manager, pip, setup.py or a tarball,
       please use that to update.  Note that Ubuntu packages do not seem to get updated  anymore.
       Since  we  are not affiliated with Ubuntu, there is little we can do.  Feel free to report
       bugs   (https://bugs.launchpad.net/ubuntu/+source/youtube-dl/+filebug)   to   the   Ubuntu
       packaging                               guys                               (mailto:ubuntu-
       motu@lists.ubuntu.com?subject=outdated%20version%20of%20youtube-dl) - all they have to  do
       is update the package to a somewhat recent version.  See above for a way to update.

   Do I always have to pass -citw?
       By  default,  youtube-dl  intends  to  have  the best options (incidentally, if you have a
       convincing case that these should be different, please file an  issue  where  you  explain
       that (https://yt-dl.org/bug)).  Therefore, it is unnecessary and sometimes harmful to copy
       long option strings from webpages.  In particular, the only option out of  -citw  that  is
       regularly useful is -i.

   Can you please put the -b option back?
       Most people asking this question are not aware that youtube-dl now defaults to downloading
       the highest available quality as reported by YouTube, which will be 1080p or 720p in  some
       cases,  so you no longer need the -b option.  For some specific videos, maybe YouTube does
       not report them to be available in a specific high quality format  you're  interested  in.
       In that case, simply request it with the -f option and youtube-dl will try to download it.

   I get HTTP error 402 when trying to download a video. What's
       this?

       Apparently  YouTube  requires  you to pass a CAPTCHA test if you download too much.  We're
       considering to provide a way to let you solve the CAPTCHA (https://github.com/rg3/youtube-
       dl/issues/154),  but at the moment, your best course of action is pointing a webbrowser to
       the youtube URL, solving the CAPTCHA, and restart youtube-dl.

   Do I need any other programs?
       youtube-dl works fine on its  own  on  most  sites.   However,  if  you  want  to  convert
       video/audio,  you'll need avconv (https://libav.org/) or ffmpeg (https://www.ffmpeg.org/).
       On some sites - most notably YouTube - videos can be retrieved in a higher quality  format
       without  sound.  youtube-dl will detect whether avconv/ffmpeg is present and automatically
       pick the best option.

       Videos or video formats streamed via RTMP protocol can only be  downloaded  when  rtmpdump
       (https://rtmpdump.mplayerhq.hu/)  is  installed.  Downloading MMS and RTSP videos requires
       either mplayer (http://mplayerhq.hu/) or mpv (https://mpv.io/) to be installed.

   I have downloaded a video but how can I play it?
       Once  the  video  is   fully   downloaded,   use   any   video   player,   such   as   vlc
       (http://www.videolan.org) or mplayer (http://www.mplayerhq.hu/).

   I extracted a video URL with -g, but it does not play on
       another machine / in my webbrowser.

       It  depends a lot on the service.  In many cases, requests for the video (to download/play
       it) must come from the same IP address and with  the  same  cookies.   Use  the  --cookies
       option  to  write  the  required  cookies  into a file, and advise your downloader to read
       cookies from that file.  Some sites also require a common  user  agent  to  be  used,  use
       --dump-user-agent to see the one in use by youtube-dl.

       It  may  be  beneficial  to  use IPv6; in some cases, the restrictions are only applied to
       IPv4.  Some services (sometimes only for a subset of videos) do not restrict the video URL
       by IP address, cookie, or user-agent, but these are the exception rather than the rule.

       Please  bear in mind that some URL protocols are not supported by browsers out of the box,
       including RTMP.  If you are using -g, your own downloader must support these as well.

       If you want to play the video on a machine that is not running youtube-dl, you  can  relay
       the  video  content  from  the  machine  that  runs  youtube-dl.   You can use -o - to let
       youtube-dl stream a video to stdout, or simply allow the  player  to  download  the  files
       written by youtube-dl in turn.

   ERROR: no fmt_url_map or conn information found in video info
       YouTube has switched to a new video info format in July 2011 which is not supported by old
       versions of  youtube-dl.   See  above  (#how-do-i-update-youtube-dl)  for  how  to  update
       youtube-dl.

   ERROR: unable to download video
       YouTube  requires  an  additional signature since September 2012 which is not supported by
       old versions of youtube-dl.  See above (#how-do-i-update-youtube-dl)  for  how  to  update
       youtube-dl.

   Video URL contains an ampersand and I'm getting some strange
       output [1] 2839 or 'v' is not recognized as an internal or external command

       That's  actually  the output from your shell.  Since ampersand is one of the special shell
       characters it's interpreted by the shell preventing you from  passing  the  whole  URL  to
       youtube-dl.   To disable your shell from interpreting the ampersands (or any other special
       characters) you have to either put the whole URL in quotes or escape them with a backslash
       (which approach will work depends on your shell).

       For  example if your URL is https://www.youtube.com/watch?t=4&v=BaW_jenozKc you should end
       up with following command:

       youtube-dl 'https://www.youtube.com/watch?t=4&v=BaW_jenozKc'

       or

       youtube-dl https://www.youtube.com/watch?t=4\&v=BaW_jenozKc

       For Windows you have to use the double quotes:

       youtube-dl "https://www.youtube.com/watch?t=4&v=BaW_jenozKc"

   ExtractorError: Could not find JS function u'OF'
       In February 2015, the new YouTube player contained a character sequence in a  string  that
       was misinterpreted by old versions of youtube-dl.  See above (#how-do-i-update-youtube-dl)
       for how to update youtube-dl.

   HTTP Error 429: Too Many Requests or 402: Payment Required
       These two error codes indicate that the service is blocking your  IP  address  because  of
       overuse.   Contact  the  service and ask them to unblock your IP address, or - if you have
       acquired a whitelisted IP address already - use the --proxy  or  --source-address  options
       (#network-options) to select another IP address.

   SyntaxError: Non-ASCII character
       The error

              File "youtube-dl", line 2
              SyntaxError: Non-ASCII character '\x93' ...

       means you're using an outdated version of Python.  Please update to Python 2.6 or 2.7.

   What is this binary file? Where has the code gone?
       Since  June  2012  (#342)  youtube-dl  is packed as an executable zipfile, simply unzip it
       (might need renaming to youtube-dl.zip first on some systems) or clone the git repository,
       as  laid  out  above.  If you modify the code, you can run it by executing the __main__.py
       file.  To recompile the executable, run make youtube-dl.

   The exe throws a Runtime error from Visual C++
       To run the exe you need to install first the Microsoft  Visual  C++  2008  Redistributable
       Package (http://www.microsoft.com/en-us/download/details.aspx?id=29).

   On Windows, how should I set up ffmpeg and youtube-dl? Where should
       I put the exe files?

       If  you  put  youtube-dl  and ffmpeg in the same directory that you're running the command
       from, it will work, but that's rather cumbersome.

       To make a different directory work - either for ffmpeg, or for youtube-dl, or for  both  -
       simply  create  the  directory  (say,  C:\bin,  or  C:\Users\<User name>\bin), put all the
       executables  directly  in  there,  and   then   set   your   PATH   environment   variable
       (https://www.java.com/en/download/help/path.xml) to include that directory.

       From  then on, after restarting your shell, you will be able to access both youtube-dl and
       ffmpeg (and youtube-dl will be able to find ffmpeg) by simply typing youtube-dl or ffmpeg,
       no matter what directory you're in.

   How do I put downloads into a specific folder?
       Use   the   -o   to   specify   an   output   template   (#output-template),  for  example
       -o "/home/user/videos/%(title)s-%(id)s.%(ext)s".   If  you  want  this  for  all  of  your
       downloads, put the option into your configuration file (#configuration).

   How do I download a video starting with a -?
       Either  prepend  http://www.youtube.com/watch?v=  or separate the ID from the options with
       --:

              youtube-dl -- -wNyEUrxzFU
              youtube-dl "http://www.youtube.com/watch?v=-wNyEUrxzFU"

   How do I pass cookies to youtube-dl?
       Use the --cookies option, for example --cookies /path/to/cookies/file.txt.  Note that  the
       cookies  file  must  be  in Mozilla/Netscape format and the first line of the cookies file
       must be either # HTTP Cookie File or  # Netscape HTTP Cookie File.   Make  sure  you  have
       correct  newline  format  (https://en.wikipedia.org/wiki/Newline)  in the cookies file and
       convert newlines if necessary to correspond with your OS, namely CRLF (\r\n) for  Windows,
       LF  (\n)  for  Linux  and  CR  (\r)  for  Mac  OS.  HTTP Error 400: Bad Request when using
       --cookies is a good sign of invalid newline format.

       Passing cookies to youtube-dl is  a  good  way  to  workaround  login  when  a  particular
       extractor  does  not  implement it explicitly.  Another use case is working around CAPTCHA
       (https://en.wikipedia.org/wiki/CAPTCHA) some websites require you to solve  in  particular
       cases in order to get access (e.g.  YouTube, CloudFlare).

   Can you add support for this anime video site, or site which shows
       current movies for free?

       As  a  matter  of  policy  (as  well as legality), youtube-dl does not include support for
       services that specialize in infringing copyright.  As a  rule  of  thumb,  if  you  cannot
       easily  find a video that the service is quite obviously allowed to distribute (i.e.  that
       has been uploaded by the creator, the creator's distributor, or is published under a  free
       license), the service is probably unfit for inclusion to youtube-dl.

       A  note on the service that they don't host the infringing content, but just link to those
       who do, is evidence that the service should not be included  into  youtube-dl.   The  same
       goes for any DMCA note when the whole front page of the service is filled with videos they
       are not allowed to distribute.  A "fair use" note is equally unconvincing if  the  service
       shows copyright-protected videos in full without authorization.

       Support  requests for services that do purchase the rights to distribute their content are
       perfectly fine though.  If in doubt, you can simply include a  source  that  mentions  the
       legitimate purchase of content.

   How can I speed up work on my issue?
       (Also  known as: Help, my important issue not being solved!) The youtube-dl core developer
       team is quite small.  While we do our best to solve as many issues as possible,  sometimes
       that can take quite a while.  To speed up your issue, here's what you can do:

       First  of  all,  please do report the issue at our issue tracker (https://yt-dl.org/bugs).
       That allows us to coordinate all efforts by users and developers, and serves as a  unified
       point.  Unfortunately, the youtube-dl project has grown too large to use personal email as
       an effective communication channel.

       Please read the bug reporting instructions (#bugs) below.  A lot  of  bugs  lack  all  the
       necessary  information.   If  you can, offer proxy, VPN, or shell access to the youtube-dl
       developers.  If you are able to, test  the  issue  from  multiple  computers  in  multiple
       countries to exclude local censorship or misconfiguration issues.

       If  nobody  is interested in solving your issue, you are welcome to take matters into your
       own hands and submit a pull request (or coerce/pay somebody else to do so).

       Feel free to bump the issue from time to time by writing a small comment ("Issue is  still
       present  in  youtube-dl  version  ...from France, but fixed from Belgium"), but please not
       more than once a month.  Please do not declare your issue as important or urgent.

   How can I detect whether a given URL is supported by youtube-dl?
       For one, have a look at the list of supported sites (docs/supportedsites.md).   Note  that
       it   can   sometimes   happen   that   the   site   changes  its  URL  scheme  (say,  from
       http://example.com/video/1234567 to http://example.com/v/1234567 ) and youtube-dl  reports
       an URL of a service in that list as unsupported.  In that case, simply report a bug.

       It is not possible to detect whether a URL is supported or not.  That's because youtube-dl
       contains a generic extractor which matches all URLs.   You  may  be  tempted  to  disable,
       exclude,  or remove the generic extractor, but the generic extractor not only allows users
       to extract videos from lots of websites that embed a video from another service,  but  may
       also  be  used  to  extract  video from a service that it's hosting itself.  Therefore, we
       neither recommend nor support disabling, excluding, or removing the generic extractor.

       If you want to find out whether a given URL is supported, simply call youtube-dl with  it.
       If  you  get  no  videos  back,  chances are the URL is either not referring to a video or
       unsupported.  You can find out which by examining the output (if you run youtube-dl on the
       console) or catching an UnsupportedError exception if you run it from a Python program.

DEVELOPER INSTRUCTIONS

       Most   users   do   not   need   to   build   youtube-dl   and  can  download  the  builds
       (http://rg3.github.io/youtube-dl/download.html) or get them from their distribution.

       To run youtube-dl as a developer, you don't need to build anything either.  Simply execute

              python -m youtube_dl

       To run the test, simply invoke your favorite test runner, or execute a test file directly;
       any of the following work:

              python -m unittest discover
              python test/test_download.py
              nosetests

       If you want to create a build of youtube-dl yourself, you'll need

       · python

       · make

       · pandoc

       · zip

       · nosetests

   Adding support for a new site
       If  you  want to add support for a new site, you can follow this quick list (assuming your
       service is called yourextractor):

        1. Fork this repository (https://github.com/rg3/youtube-dl/fork)

        2. Check            out            the            source            code             with
           git clone git@github.com:YOUR_GITHUB_USERNAME/youtube-dl.git

        3. Start a new git branch with cd youtube-dl; git checkout -b yourextractor

        4. Start with this simple template and save it to youtube_dl/extractor/yourextractor.py:

                  # coding: utf-8
                  from __future__ import unicode_literals

                  from .common import InfoExtractor

                  class YourExtractorIE(InfoExtractor):
                      _VALID_URL = r'https?://(?:www\.)?yourextractor\.com/watch/(?P<id>[0-9]+)'
                      _TEST = {
                          'url': 'http://yourextractor.com/watch/42',
                          'md5': 'TODO: md5 sum of the first 10241 bytes of the video file (use --test)',
                          'info_dict': {
                              'id': '42',
                              'ext': 'mp4',
                              'title': 'Video title goes here',
                              'thumbnail': 're:^https?://.*\.jpg$',
                              # TODO more properties, either as:
                              # * A value
                              # * MD5 checksum; start the string with md5:
                              # * A regular expression; start the string with re:
                              # * Any Python type (for example int or float)
                          }
                      }

                      def _real_extract(self, url):
                          video_id = self._match_id(url)
                          webpage = self._download_webpage(url, video_id)

                          # TODO more code goes here, for example ...
                          title = self._html_search_regex(r'<h1>(.+?)</h1>', webpage, 'title')

                          return {
                              'id': video_id,
                              'title': title,
                              'description': self._og_search_description(webpage),
                              'uploader': self._search_regex(r'<div[^>]+id="uploader"[^>]*>([^<]+)<', webpage, 'uploader', fatal=False),
                              # TODO more properties (see youtube_dl/extractor/common.py)
                          }

        5. Add  an  import  in  youtube_dl/extractor/__init__.py (https://github.com/rg3/youtube-
           dl/blob/master/youtube_dl/extractor/__init__.py).

        6. Run python test/test_download.py TestDownload.test_YourExtractor.  This should fail at
           first, but you can continually re-run it until you're done.  If you decide to add more
           than one test, then rename _TEST to _TESTS and make it into a  list  of  dictionaries.
           The      tests     will     then     be     named     TestDownload.test_YourExtractor,
           TestDownload.test_YourExtractor_1, TestDownload.test_YourExtractor_2, etc.

        7. Have  a  look   at   youtube_dl/extractor/common.py   (https://github.com/rg3/youtube-
           dl/blob/master/youtube_dl/extractor/common.py)  for  possible  helper  methods  and  a
           detailed   description   of   what   your   extractor   should    and    may    return
           (https://github.com/rg3/youtube-
           dl/blob/master/youtube_dl/extractor/common.py#L62-L200).  Add tests and  code  for  as
           many as you want.

        8. If you can, check the code with flake8 (https://pypi.python.org/pypi/flake8).

        9. When  the  tests  pass, add (http://git-scm.com/docs/git-add) the new files and commit
           (http://git-scm.com/docs/git-commit) them and push  (http://git-scm.com/docs/git-push)
           the result, like this:

                  $ git add youtube_dl/extractor/__init__.py
                  $ git add youtube_dl/extractor/yourextractor.py
                  $ git commit -m '[yourextractor] Add new extractor'
                  $ git push origin yourextractor

       10. Finally,  create  a  pull  request  (https://help.github.com/articles/creating-a-pull-
           request).  We'll then review and merge it.

       In any case, thank you very much for your contributions!

EMBEDDING YOUTUBE-DL

       youtube-dl makes the best effort to be a good command-line program,  and  thus  should  be
       callable from any programming language.  If you encounter any problems parsing its output,
       feel free to create a report (https://github.com/rg3/youtube-dl/issues/new).

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

              from __future__ import unicode_literals
              import youtube_dl

              ydl_opts = {}
              with youtube_dl.YoutubeDL(ydl_opts) as ydl:
                  ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])

       Most likely, you'll want to use various options.  For a list of what can be done,  have  a
       look          at          youtube_dl/YoutubeDL.py         (https://github.com/rg3/youtube-
       dl/blob/master/youtube_dl/YoutubeDL.py#L121-L269).  For a start, if you want to  intercept
       youtube-dl's output, set a logger object.

       Here's  a more complete example of a program that outputs only errors (and a short message
       after the download is finished), and downloads/converts the video to an mp3 file:

              from __future__ import unicode_literals
              import youtube_dl

              class MyLogger(object):
                  def debug(self, msg):
                      pass

                  def warning(self, msg):
                      pass

                  def error(self, msg):
                      print(msg)

              def my_hook(d):
                  if d['status'] == 'finished':
                      print('Done downloading, now converting ...')

              ydl_opts = {
                  'format': 'bestaudio/best',
                  'postprocessors': [{
                      'key': 'FFmpegExtractAudio',
                      'preferredcodec': 'mp3',
                      'preferredquality': '192',
                  }],
                  'logger': MyLogger(),
                  'progress_hooks': [my_hook],
              }
              with youtube_dl.YoutubeDL(ydl_opts) as ydl:
                  ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])

BUGS

       Bugs and suggestions should be  reported  at:  <https://github.com/rg3/youtube-dl/issues>.
       Unless  you  were  prompted so or there is another pertinent reason (e.g.  GitHub fails to
       accept the bug  report),  please  do  not  send  bug  reports  via  personal  email.   For
       discussions,  join us in the IRC channel #youtube-dl (irc://chat.freenode.net/#youtube-dl)
       on freenode (webchat (http://webchat.freenode.net/?randomnick=1&channels=youtube-dl)).

       Please include the full output of youtube-dl when run with -v, i.e.  add -v flag  to  your
       command  line,  copy  the  whole  output  and post it in the issue body wrapped in ``` for
       better formatting.  It should look similar to this:

       The output (including the first lines) contains important debugging  information.   Issues
       without  the  full  output  are  often not reproducible and therefore do not get solved in
       short order, if ever.

       Please re-read your issue once again to avoid a couple of common  mistakes  (you  can  and
       should use this as a checklist):

   Is the description of the issue itself sufficient?
       We  often  get  issue  reports  that  we  cannot  really decipher.  While in most cases we
       eventually get the required information after asking back multiple times,  this  poses  an
       unnecessary  drain  on  our  resources.  Many contributors, including myself, are also not
       native speakers, so we may misread some parts.

       So please elaborate on what feature you are requesting, or what bug you want to be  fixed.
       Make sure that it's obvious

       · What the problem is

       · How it could be fixed

       · How your proposed solution would look like

       If  your  report  is shorter than two lines, it is almost certainly missing some of these,
       which makes it hard for us to respond to it.  We're often too polite to  close  the  issue
       outright,  but  the missing info makes misinterpretation likely.  As a committer myself, I
       often get frustrated by these issues, since the only possible way for me to  move  forward
       on them is to ask for clarification over and over.

       For  bug  reports,  this  means  that  your  report  should contain the complete output of
       youtube-dl when called with the -v flag.  The error message you get for (most)  bugs  even
       says  so,  but  you  would  not  believe  how  many of our bug reports do not contain this
       information.

       If your server has multiple IPs or you suspect censorship, adding  --call-home  may  be  a
       good  idea  to get more diagnostics.  If the error is ERROR: Unable to extract ... and you
       cannot reproduce it from multiple countries, add --dump-pages (warning: this will yield  a
       rather  large  output,  redirect  it  to  the file log.txt by adding >log.txt 2>&1 to your
       command-line) or upload the .dump files you  get  when  you  add  --write-pages  somewhere
       (https://gist.github.com/).

       Site support requests must contain an example URL.  An example URL is a URL you might want
       to download, like http://www.youtube.com/watch?v=BaW_jenozKc.  There should be an  obvious
       video  present.  Except under very special circumstances, the main page of a video service
       (e.g.  http://www.youtube.com/) is not an example URL.

   Are you using the latest version?
       Before  reporting  any  issue,  type  youtube-dl -U.   This  should  report  that   you're
       up-to-date.   About  20% of the reports we receive are already fixed, but people are using
       outdated versions.  This goes for feature requests as well.

   Is the issue already documented?
       Make sure that someone has not already opened the issue you're trying to open.  Search  at
       the  top  of  the  window  or  browse  the  GitHub Issues (https://github.com/rg3/youtube-
       dl/search?type=Issues) of this repository.  If there is  an  issue,  feel  free  to  write
       something  along  the lines of "This affects me as well, with version 2015.01.01.  Here is
       some more information on the issue: ...".  While some issues may be old, a new  post  into
       them often spurs rapid activity.

   Why are existing options not enough?
       Before requesting a new feature, please have a quick peek at the list of supported options
       (https://github.com/rg3/youtube-dl/blob/master/README.md#synopsis).  Many feature requests
       are for features that actually exist already!  Please, absolutely do show off your work in
       the issue report and detail how the existing similar options do not solve your problem.

   Is there enough context in your bug report?
       People want to solve problems, and often think they do us a favor by breaking  down  their
       larger  problems  (e.g.   wanting  to skip already downloaded files) to a specific request
       (e.g.  requesting us to look whether the file exists before downloading  the  info  page).
       However,  what  often  happens  is  that  they  break down the problem into two steps: One
       simple, and one impossible (or extremely complicated one).

       We are then presented with a very complicated request when the original problem  could  be
       solved  far  easier,  e.g.   by recording the downloaded video IDs in a separate file.  To
       avoid this, you must include the greater context where it is non-obvious.  In  particular,
       every  feature  request  that  does  not  consist  of adding support for a new site should
       contain a use case scenario that explains in what situation the missing feature  would  be
       useful.

   Does the issue involve one problem, and one problem only?
       Some of our users seem to think there is a limit of issues they can or should open.  There
       is no limit of issues they can or should open.  While it may seem appealing to be able  to
       dump  all  your  issues  into  one  ticket, that means that someone who solves one of your
       issues cannot mark the issue as closed.  Typically, reporting a bunch of issues  leads  to
       the  ticket lingering since nobody wants to attack that behemoth, until someone mercifully
       splits the issue into multiple ones.

       In particular, every site support request issue should only pertain  to  services  at  one
       site  (generally under a common domain, but always using the same backend technology).  Do
       not request support for vimeo user videos, Whitehouse podcasts, and Google Plus  pages  in
       the  same  issue.   Also,  make  sure  that  you  don't post bug reports alongside feature
       requests.  As a rule of thumb, a feature request does not include  outputs  of  youtube-dl
       that are not immediately related to the feature at hand.  Do not post reports of a network
       error alongside the request for a new video service.

   Is anyone going to need the feature?
       Only post features that you (or an  incapacitated  friend  you  can  personally  talk  to)
       require.   Do  not  post  features because they seem like a good idea.  If they are really
       useful, they will be requested by someone who requires them.

   Is your question about youtube-dl?
       It may sound strange, but  some  bug  reports  we  receive  are  completely  unrelated  to
       youtube-dl  and relate to a different or even the reporter's own application.  Please make
       sure that you are actually using youtube-dl.  If you are using a UI for youtube-dl, report
       the  bug to the maintainer of the actual application providing the UI.  On the other hand,
       if your UI for youtube-dl fails in some way you believe is related to youtube-dl,  by  all
       means, go ahead and report the bug.
