.SH CONFIGURATION
.PP
You can configure youtube\-dl by placing default arguments (such as
\f[C]\-\-extract\-audio\ \-\-no\-mtime\f[] to always extract the audio
and not copy the mtime) into \f[C]/etc/youtube\-dl.conf\f[] and/or
\f[C]~/.config/youtube\-dl.conf\f[].
.SH OUTPUT TEMPLATE
.PP
The \f[C]\-o\f[] 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
\f[C]youtube\-dl\ \-o\ funny_video.flv\ "http://some/video"\f[].
However, it may contain special sequences that will be replaced when
downloading each video.
The special sequences have the format \f[C]%(NAME)s\f[].
To clarify, that is a percent symbol followed by a name in parenthesis,
followed by a lowercase S.
Allowed names are:
.IP \[bu] 2
\f[C]id\f[]: The sequence will be replaced by the video identifier.
.IP \[bu] 2
\f[C]url\f[]: The sequence will be replaced by the video URL.
.IP \[bu] 2
\f[C]uploader\f[]: The sequence will be replaced by the nickname of the
person who uploaded the video.
.IP \[bu] 2
\f[C]upload_date\f[]: The sequence will be replaced by the upload date
in YYYYMMDD format.
.IP \[bu] 2
\f[C]title\f[]: The sequence will be replaced by the video title.
.IP \[bu] 2
\f[C]ext\f[]: The sequence will be replaced by the appropriate extension
(like flv or mp4).
.IP \[bu] 2
\f[C]epoch\f[]: The sequence will be replaced by the Unix epoch when
creating the file.
.IP \[bu] 2
\f[C]autonumber\f[]: The sequence will be replaced by a five\-digit
number that will be increased with each download, starting at zero.
.IP \[bu] 2
\f[C]playlist\f[]: The name or the id of the playlist that contains the
video.
.IP \[bu] 2
\f[C]playlist_index\f[]: The index of the video in the playlist, a
five\-digit number.
.PP
The current default template is \f[C]%(id)s.%(ext)s\f[], but that will
be switchted to \f[C]%(title)s\-%(id)s.%(ext)s\f[] (which can be
requested with \f[C]\-t\f[] at the moment).
.PP
In some cases, you don\[aq]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 \f[C]\-\-restrict\-filenames\f[] flag to get a
shorter title:
.IP
.nf
\f[C]
$\ youtube\-dl\ \-\-get\-filename\ \-o\ "%(title)s.%(ext)s"\ BaW_jenozKc
youtube\-dl\ test\ video\ \[aq]\[aq]_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
\f[]
.fi
.SH VIDEO SELECTION
.PP
Videos can be filtered by their upload date using the options
\f[C]\-\-date\f[], \f[C]\-\-datebefore\f[] or \f[C]\-\-dateafter\f[],
they accept dates in two formats:
.IP \[bu] 2
Absolute dates: Dates in the format \f[C]YYYYMMDD\f[].
.IP \[bu] 2
Relative dates: Dates in the format
\f[C](now|today)[+\-][0\-9](day|week|month|year)(s)?\f[]
.PP
Examples:
.IP
.nf
\f[C]
$\ youtube\-dl\ \-\-dateafter\ now\-6months\ #will\ only\ download\ the\ videos\ uploaded\ in\ the\ last\ 6\ months
$\ youtube\-dl\ \-\-date\ 19700101\ #will\ only\ download\ the\ videos\ uploaded\ in\ January\ 1,\ 1970
$\ youtube\-dl\ \-\-dateafter\ 20000101\ \-\-datebefore\ 20100101\ #will\ only\ download\ the\ videos\ uploaded\ between\ 2000\ and\ 2010

.SH FAQ
.SS Can you please put the \-b option back?
.PP
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\[aq]\[aq]re interested
in.
In that case, simply request it with the \-f option and youtube\-dl will
try to download it.
.SS I get HTTP error 402 when trying to download a video. What\[aq]s
this?
.PP
Apparently YouTube requires you to pass a CAPTCHA test if you download
too much.
We\[aq]\[aq]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.
.SS I have downloaded a video but how can I play it?
.PP
Once the video is fully downloaded, use any video player, such as
vlc (http://www.videolan.org) or mplayer (http://www.mplayerhq.hu/).
.SS The links provided by youtube\-dl \-g are not working anymore
.PP
The URLs youtube\-dl outputs require the downloader to have the correct
cookies.
Use the \f[C]\-\-cookies\f[] 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
\f[C]\-\-dump\-user\-agent\f[] to see the one in use by youtube\-dl.
.SS ERROR: no fmt_url_map or conn information found in video info
.PP
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 \f[C]sudo\ youtube\-dl\ \-\-update\f[].
.SS ERROR: unable to download video
.PP
youtube requires an additional signature since September 2012 which is
not supported by old versions of youtube\-dl.

Please update to Python 2.6 or 2.7.
.SS What is this binary file? Where has the code gone?
.PP
Since June 2012 (#342) youtube\-dl is packed as an executable zipfile,
simply unzip it (might need renaming to \f[C]youtube\-dl.zip\f[] 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
\f[C]__main__.py\f[] file.
To recompile the executable, run \f[C]make\ youtube\-dl\f[].
.SS The exe throws a \f[I]Runtime error from Visual C++\f[]
.PP
To run the exe you need to install first the Microsoft Visual C++ 2008

Your exact command line, like

A common mistake is not to escape the \f[C]&\f[].
Putting URLs in quotes should solve this problem.
