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.
