CONFIGURATION

       You can configure youtube-dl by placing default arguments (such as --extract-audio --no-mtime  to  always
       extract the audio and not copy the mtime) into /etc/youtube-dl.conf and/or ~/.config/youtube-dl.conf.  On
       Windows,    the    configuration    file    locations     are     %APPDATA%\youtube-dl\config.txt     and
       C:\Users\<Yourname>\youtube-dl.conf.

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 parenthesis, followed by a lowercase S.  Allowed names
       are:

       • id: The sequence will be replaced by the video identifier.

       • url: The sequence will be replaced by the video URL.

       • uploader: The sequence will be replaced by the nickname of the person who uploaded the video.

       • upload_date: The sequence will be replaced by the upload date in YYYYMMDD format.

       • title: The sequence will be replaced by the video title.

       • ext: The sequence will be replaced by the appropriate extension (like flv or mp4).

       • epoch: The sequence will be replaced by the Unix epoch when creating the file.

       • autonumber: The sequence will be replaced by a five-digit number  that  will  be  increased  with  each
         download, starting at zero.

       • playlist: The name or the id of the playlist that contains the video.

       • playlist_index: The index of the video in the playlist, a five-digit number.

       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:

              $ 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

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

FAQ

   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.

   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/).

   The links provided by youtube-dl -g are not working anymore
       The URLs youtube-dl outputs require the downloader to have the correct 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.

   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.  You can update youtube-dl with sudo youtube-dl --update.

   ERROR: unable to download video
       youtube requires an additional signature since September 2012 which is not supported by old  versions  of
       youtube-dl.  You can update youtube-dl with sudo youtube-dl --update.

   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).

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, copy any recently modified (https://github.com/rg3/youtube-
       dl/commits/master/youtube_dl/extractor)   file   in    youtube_dl/extractor,    add    an    import    in
       youtube_dl/extractor/__init__.py                                         (https://github.com/rg3/youtube-
       dl/blob/master/youtube_dl/extractor/__init__.py).  Have a look  at  youtube_dl/common/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 return  (https://github.com/rg3/youtube-
       dl/blob/master/youtube_dl/extractor/common.py#L38).     Don't    forget    to    run   the   tests   with
       python test/test_download.py Test_Download.test_YourExtractor!  For a detailed tutorial,  refer  to  this
       blog post (http://filippo.io/add-support-for-a-new-video-site-to-youtube-dl/).

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.

       Please  include  the full output of the command when run with --verbose.  The output (including the first
       lines)  contain  important  debugging  information.   Issues  without  the  full  output  are  often  not
       reproducible and therefore do not get solved in short order, if ever.

       For discussions, join us in the irc channel #youtube-dl on freenode.

       When  you  submit a request, please re-read it once to avoid a couple of 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 commiter 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.

       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 at https://github.com/rg3/youtube-dl/search?type=Issues .  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 incapicated 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.
