\f[B]youtube\-dl\f[] [OPTIONS] URL [URL...]
.SH DESCRIPTION
.PP
\f[B]youtube\-dl\f[] 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.

.SH CONFIGURATION
.PP
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
\f[C]/etc/youtube\-dl.conf\f[] and the user wide configuration file at
\f[C]~/.config/youtube\-dl/config\f[].
On Windows, the user wide configuration file locations are
\f[C]%APPDATA%\\youtube\-dl\\config.txt\f[] or
\f[C]C:\\Users\\<user\ name>\\youtube\-dl.conf\f[].
For example, with the following configuration file youtube\-dl will
always extract the audio, not copy the mtime and use a proxy:
.IP
.nf
\f[C]
\-\-extract\-audio
\-\-no\-mtime
\-\-proxy\ 127.0.0.1:3128
\f[]
.fi
.PP
You can use \f[C]\-\-ignore\-config\f[] if you want to disable the
configuration file for a particular youtube\-dl run.
.SS Authentication with \f[C]\&.netrc\f[] file
.PP
You may also want to configure automatic credentials storage for
extractors that support authentication (by providing login and password
with \f[C]\-\-username\f[] and \f[C]\-\-password\f[]) 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 \f[C]\&.netrc\f[]
file (http://stackoverflow.com/tags/.netrc/info) on per extractor basis.
For that you will need to create a\f[C]\&.netrc\f[] file in your
\f[C]$HOME\f[] and restrict permissions to read/write by you only:
.IP
.nf
\f[C]
touch\ $HOME/.netrc
chmod\ a\-rwx,u+rw\ $HOME/.netrc
\f[]
.fi
.PP
After that you can add credentials for extractor in the following
format, where \f[I]extractor\f[] is the name of extractor in lowercase:
.IP
.nf
\f[C]
machine\ <extractor>\ login\ <login>\ password\ <password>
\f[]
.fi
.PP
For example:
.IP
.nf
\f[C]
machine\ youtube\ login\ myaccount\@gmail.com\ password\ my_youtube_password
machine\ twitch\ login\ my_twitch_account_name\ password\ my_twitch_password
\f[]
.fi
.PP
To activate authentication with the \f[C]\&.netrc\f[] file you should
pass \f[C]\-\-netrc\f[] to youtube\-dl or place it in the configuration
file (#configuration).
.PP
On Windows you may also need to setup the \f[C]%HOME%\f[] environment
variable manually.
.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 parentheses,
followed by a lowercase S.
Allowed names are:
.IP \[bu] 2
\f[C]id\f[]: Video identifier
.IP \[bu] 2
\f[C]title\f[]: Video title

For example for \f[C]\-o\ %(title)s\-%(id)s.%(ext)s\f[] and mp4 video
with title \f[C]youtube\-dl\ test\ video\f[] and id
\f[C]BaW_jenozKcj\f[] this will result in a

Output template can also contain arbitrary hierarchical path, e.g.
\f[C]\-o\ \[aq]%(playlist)s/%(playlist_index)s\ \-\ %(title)s.%(ext)s\[aq]\f[]
that will result in downloading each video in a directory corresponding

.SH FORMAT SELECTION
.PP
By default youtube\-dl tries to download the best available quality,
i.e.
if you want the best quality you \f[B]don\[aq]t need\f[] to pass any
special options, youtube\-dl will guess it for you by \f[B]default\f[].
.PP
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 \f[I]format
selection\f[] based on which you can explicitly specify desired format,
select formats based on some criterion or criteria, setup precedence and
much more.
.PP
The general syntax for format selection is \f[C]\-\-format\ FORMAT\f[]
or shorter \f[C]\-f\ FORMAT\f[] where \f[C]FORMAT\f[] is a \f[I]selector
expression\f[], i.e.
an expression that describes format or formats you would like to
download.
.PP
The simplest case is requesting a specific format, for example with
\f[C]\-f\ 22\f[] you can download the format with format code equal to
22.
You can get the list of available format codes for particular video
using \f[C]\-\-list\-formats\f[] or \f[C]\-F\f[].
Note that these format codes are extractor specific.
.PP
You can also use a file extension (currently \f[C]3gp\f[], \f[C]aac\f[],
\f[C]flv\f[], \f[C]m4a\f[], \f[C]mp3\f[], \f[C]mp4\f[], \f[C]ogg\f[],
\f[C]wav\f[], \f[C]webm\f[] are supported) to download best quality
format of particular file extension served as a single file, e.g.
\f[C]\-f\ webm\f[] will download best quality format with \f[C]webm\f[]
extension served as a single file.
.PP
You can also use special names to select particular edge case format: \-
\f[C]best\f[]: Select best quality format represented by single file
with video and audio \- \f[C]worst\f[]: Select worst quality format
represented by single file with video and audio \- \f[C]bestvideo\f[]:
Select best quality video only format (e.g.
DASH video), may not be available \- \f[C]worstvideo\f[]: Select worst
quality video only format, may not be available \- \f[C]bestaudio\f[]:
Select best quality audio only format, may not be available \-
\f[C]worstaudio\f[]: Select worst quality audio only format, may not be
available
.PP
For example, to download worst quality video only format you can use
\f[C]\-f\ worstvideo\f[].
.PP
If you want to download multiple videos and they don\[aq]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[C]\-f\ 22/17/18\f[] will download format 22 if it\[aq]s available,
otherwise it will download format 17 if it\[aq]s available, otherwise it
will download format 18 if it\[aq]s available, otherwise it will
complain that no suitable formats are available for download.
.PP
If you want to download several formats of the same video use comma as a
separator, e.g.
\f[C]\-f\ 22,17,18\f[] will download all these three formats, of course
if they are available.
Or more sophisticated example combined with precedence feature
\f[C]\-f\ 136/137/mp4/bestvideo,140/m4a/bestaudio\f[].
.PP
You can also filter the video formats by putting a condition in
brackets, as in \f[C]\-f\ "best[height=720]"\f[] (or
\f[C]\-f\ "[filesize>10M]"\f[]).
.PP
The following numeric meta fields can be used with comparisons
\f[C]<\f[], \f[C]<=\f[], \f[C]>\f[], \f[C]>=\f[], \f[C]=\f[] (equals),
\f[C]!=\f[] (not equals): \- \f[C]filesize\f[]: The number of bytes, if
known in advance \- \f[C]width\f[]: Width of the video, if known \-
\f[C]height\f[]: Height of the video, if known \- \f[C]tbr\f[]: Average
bitrate of audio and video in KBit/s \- \f[C]abr\f[]: Average audio
bitrate in KBit/s \- \f[C]vbr\f[]: Average video bitrate in KBit/s \-
\f[C]asr\f[]: Audio sampling rate in Hertz \- \f[C]fps\f[]: Frame rate
.PP
Also filtering work for comparisons \f[C]=\f[] (equals), \f[C]!=\f[]
(not equals), \f[C]^=\f[] (begins with), \f[C]$=\f[] (ends with),
\f[C]*=\f[] (contains) and following string meta fields: \-
\f[C]ext\f[]: File extension \- \f[C]acodec\f[]: Name of the audio codec
in use \- \f[C]vcodec\f[]: Name of the video codec in use \-
\f[C]container\f[]: Name of the container format \- \f[C]protocol\f[]:
The protocol that will be used for the actual download, lower\-case.
\f[C]http\f[], \f[C]https\f[], \f[C]rtsp\f[], \f[C]rtmp\f[],
\f[C]rtmpe\f[], \f[C]m3u8\f[], or \f[C]m3u8_native\f[]
.PP
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.
.PP
Formats for which the value is not known are excluded unless you put a
question mark (\f[C]?\f[]) after the operator.
You can combine format filters, so
\f[C]\-f\ "[height\ <=?\ 720][tbr>500]"\f[] selects up to 720p videos
(or videos where the height is not known) with a bitrate of at least 500
KBit/s.
.PP
You can merge the video and audio of two formats into a single file
using \f[C]\-f\ <video\-format>+<audio\-format>\f[] (requires ffmpeg or
avconv installed), for example \f[C]\-f\ bestvideo+bestaudio\f[] will
download best video only format, best audio only format and mux them
together with ffmpeg/avconv.
.PP
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[C]\-f\ \[aq](mp4,webm)[height<480]\[aq]\f[].
.PP
Since the end of April 2015 and version 2015.04.26 youtube\-dl uses
\f[C]\-f\ bestvideo+bestaudio/best\f[] as default format selection (see
#5447, #5456).
If ffmpeg or avconv are installed this results in downloading
\f[C]bestvideo\f[] and \f[C]bestaudio\f[] separately and muxing them
together into a single file giving the best overall quality available.
Otherwise it falls back to \f[C]best\f[] and results in downloading the
best available quality served as a single file.
\f[C]best\f[] is also needed for videos that don\[aq]t come from YouTube
because they don\[aq]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[C]\-f\ bestvideo[height<=?1080]+bestaudio/best\f[] to
your configuration file.
Note that if you use youtube\-dl to stream to \f[C]stdout\f[] (and most
likely to pipe it to your media player then), i.e.
you explicitly specify output template as \f[C]\-o\ \-\f[], youtube\-dl
still uses \f[C]\-f\ best\f[] format selection in order to start content
delivery immediately to your player and not to wait until
\f[C]bestvideo\f[] and \f[C]bestaudio\f[] are downloaded and muxed.
.PP
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[C]\-f\ best\f[].
You may want to add it to the configuration file (#configuration) in
order not to type it every time you run youtube\-dl.

.SH FAQ
.SS How do I update youtube\-dl?
.PP
If you\[aq]ve followed our manual installation
instructions (http://rg3.github.io/youtube-dl/download.html), you can
simply run \f[C]youtube\-dl\ \-U\f[] (or, on Linux,
\f[C]sudo\ youtube\-dl\ \-U\f[]).
.PP
If you have used pip, a simple
\f[C]sudo\ pip\ install\ \-U\ youtube\-dl\f[] is sufficient to update.
.PP
If you have installed youtube\-dl using a package manager like
\f[I]apt\-get\f[] or \f[I]yum\f[], 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.
.PP
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\[aq]s package, with a line like
.IP
.nf
\f[C]
sudo\ apt\-get\ remove\ \-y\ youtube\-dl
\f[]
.fi
.PP
Afterwards, simply follow our manual installation
instructions (http://rg3.github.io/youtube-dl/download.html):
.IP
.nf
\f[C]
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
\f[]
.fi
.PP
Again, from then on you\[aq]ll be able to update with
\f[C]sudo\ youtube\-dl\ \-U\f[].
.SS I\[aq]m getting an error
\f[C]Unable\ to\ extract\ OpenGraph\ title\f[] on YouTube playlists
.PP
YouTube changed their playlist format in March 2014 and later on, so
you\[aq]ll need at least youtube\-dl 2014.07.25 to download all YouTube
videos.
.PP
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.
.SS Do I always have to pass \f[C]\-citw\f[]?
.PP
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 \f[C]\-citw\f[] that is regularly
useful is \f[C]\-i\f[].
.SS Can you please put the \f[C]\-b\f[] 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 \f[C]\-b\f[] option.
For some specific videos, maybe YouTube does not report them to be
available in a specific high quality format you\[aq]re interested in.
In that case, simply request it with the \f[C]\-f\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]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 Do I need any other programs?
.PP
youtube\-dl works fine on its own on most sites.
However, if you want to convert video/audio, you\[aq]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.
.PP
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.
.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 I extracted a video URL with \f[C]\-g\f[], but it does not play on
another machine / in my webbrowser.
.PP
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 \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.
.PP
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.
.PP
Please bear in mind that some URL protocols are \f[B]not\f[] supported
by browsers out of the box, including RTMP.
If you are using \f[C]\-g\f[], your own downloader must support these as
well.
.PP
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 \f[C]\-o\ \-\f[] to let youtube\-dl stream a video to
stdout, or simply allow the player to download the files written by
youtube\-dl in turn.

.PP
That\[aq]s actually the output from your shell.
Since ampersand is one of the special shell characters it\[aq]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).
.PP
For example if your URL is
https://www.youtube.com/watch?t=4&v=BaW_jenozKc you should end up with
following command:
.PP
\f[C]youtube\-dl\ \[aq]https://www.youtube.com/watch?t=4&v=BaW_jenozKc\[aq]\f[]
.PP
or
.PP
\f[C]youtube\-dl\ https://www.youtube.com/watch?t=4\\&v=BaW_jenozKc\f[]

means you\[aq]re using an outdated version of Python.
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
Redistributable
Package (http://www.microsoft.com/en-us/download/details.aspx?id=29).
.SS On Windows, how should I set up ffmpeg and youtube\-dl? Where should
I put the exe files?
.PP
If you put youtube\-dl and ffmpeg in the same directory that you\[aq]re
running the command from, it will work, but that\[aq]s rather
cumbersome.
.PP
To make a different directory work \- either for ffmpeg, or for
youtube\-dl, or for both \- simply create the directory (say,
\f[C]C:\\bin\f[], or \f[C]C:\\Users\\<User\ name>\\bin\f[]), 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.
.PP
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 \f[C]youtube\-dl\f[] or \f[C]ffmpeg\f[], no
matter what directory you\[aq]re in.
.SS How do I put downloads into a specific folder?
.PP
Use the \f[C]\-o\f[] to specify an output template (#output-template),
for example \f[C]\-o\ "/home/user/videos/%(title)s\-%(id)s.%(ext)s"\f[].
If you want this for all of your downloads, put the option into your
configuration file (#configuration).
.SS How do I download a video starting with a \f[C]\-\f[]?
.PP
Either prepend \f[C]http://www.youtube.com/watch?v=\f[] or separate the
ID from the options with \f[C]\-\-\f[]:
.IP
.nf
\f[C]
youtube\-dl\ \-\-\ \-wNyEUrxzFU
youtube\-dl\ "http://www.youtube.com/watch?v=\-wNyEUrxzFU"
\f[]
.fi
.SS How do I pass cookies to youtube\-dl?
.PP
Use the \f[C]\-\-cookies\f[] option, for example
\f[C]\-\-cookies\ /path/to/cookies/file.txt\f[].
Note that the cookies file must be in Mozilla/Netscape format and the
first line of the cookies file must be either
\f[C]#\ HTTP\ Cookie\ File\f[] or
\f[C]#\ Netscape\ HTTP\ Cookie\ File\f[].
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
\f[C]CRLF\f[] (\f[C]\\r\\n\f[]) for Windows, \f[C]LF\f[] (\f[C]\\n\f[])
for Linux and \f[C]CR\f[] (\f[C]\\r\f[]) for Mac OS.
\f[C]HTTP\ Error\ 400:\ Bad\ Request\f[] when using \f[C]\-\-cookies\f[]
is a good sign of invalid newline format.
.PP
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).
.SS Can you add support for this anime video site, or site which shows
current movies for free?
.PP
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\[aq]s distributor, or
is published under a free license), the service is probably unfit for
inclusion to youtube\-dl.
.PP
A note on the service that they don\[aq]t host the infringing content,
but just link to those who do, is evidence that the service should
\f[B]not\f[] 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.
.PP
Support requests for services that \f[B]do\f[] 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.
.SS How can I speed up work on my issue?
.PP
(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\[aq]s what you can do:
.PP
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.
.PP
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.
.PP
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).
.PP
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 \f[C]important\f[] or
\f[C]urgent\f[].
.SS How can I detect whether a given URL is supported by youtube\-dl?
.PP
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.
.PP
It is \f[I]not\f[] possible to detect whether a URL is supported or not.
That\[aq]s because youtube\-dl contains a generic extractor which
matches \f[B]all\f[] 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\[aq]s hosting itself.
Therefore, we neither recommend nor support disabling, excluding, or
removing the generic extractor.
.PP
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 \f[C]UnsupportedError\f[] exception if
you run it from a Python program.
.SH DEVELOPER INSTRUCTIONS
.PP
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.

.SH EMBEDDING YOUTUBE\-DL
.PP
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).
.PP
From a Python program, you can embed youtube\-dl in a more powerful
fashion, like this:
.IP
.nf
\f[C]
from\ __future__\ import\ unicode_literals
import\ youtube_dl

ydl_opts\ =\ {}
with\ youtube_dl.YoutubeDL(ydl_opts)\ as\ ydl:
\ \ \ \ ydl.download([\[aq]http://www.youtube.com/watch?v=BaW_jenozKc\[aq]])
\f[]
.fi
.PP
Most likely, you\[aq]ll want to use various options.
For a list of what can be done, have a look at
\f[C]youtube_dl/YoutubeDL.py\f[] (https://github.com/rg3/youtube-dl/blob/master/youtube_dl/YoutubeDL.py#L121-L269).
For a start, if you want to intercept youtube\-dl\[aq]s output, set a
\f[C]logger\f[] object.
.PP
Here\[aq]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:
.IP
.nf
\f[C]
from\ __future__\ import\ unicode_literals
import\ youtube_dl


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

\ \ \ \ def\ warning(self,\ msg):
\ \ \ \ \ \ \ \ pass

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


def\ my_hook(d):

.PP
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.
.PP
Please re\-read your issue once again to avoid a couple of common
mistakes (you can and should use this as a checklist):
.SS Is the description of the issue itself sufficient?
.PP
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.
.PP
So please elaborate on what feature you are requesting, or what bug you
want to be fixed.
Make sure that it\[aq]s obvious
.IP \[bu] 2
What the problem is
.IP \[bu] 2
How it could be fixed
.IP \[bu] 2
How your proposed solution would look like
.PP
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\[aq]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.
.PP
For bug reports, this means that your report should contain the
\f[I]complete\f[] output of youtube\-dl when called with the
\f[C]\-v\f[] 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.
.PP
If your server has multiple IPs or you suspect censorship, adding
\f[C]\-\-call\-home\f[] may be a good idea to get more diagnostics.
If the error is \f[C]ERROR:\ Unable\ to\ extract\ ...\f[] and you cannot
reproduce it from multiple countries, add \f[C]\-\-dump\-pages\f[]
(warning: this will yield a rather large output, redirect it to the file
\f[C]log.txt\f[] by adding \f[C]>log.txt\ 2>&1\f[] to your
command\-line) or upload the \f[C]\&.dump\f[] files you get when you add
\f[C]\-\-write\-pages\f[] somewhere (https://gist.github.com/).
.PP
\f[B]Site support requests must contain an example URL\f[].
An example URL is a URL you might want to download, like
\f[C]http://www.youtube.com/watch?v=BaW_jenozKc\f[].
There should be an obvious video present.
Except under very special circumstances, the main page of a video
service (e.g.
\f[C]http://www.youtube.com/\f[]) is \f[I]not\f[] an example URL.
.SS Are you using the latest version?
.PP
Before reporting any issue, type \f[C]youtube\-dl\ \-U\f[].
This should report that you\[aq]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.
.SS Is the issue already documented?
.PP
Make sure that someone has not already opened the issue you\[aq]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.
.SS Why are existing options not enough?
.PP
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 \f[I]not\f[] solve your problem.
.SS Is there enough context in your bug report?
.PP
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).
.PP
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.
.SS Does the issue involve one problem, and one problem only?
.PP
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.
.PP
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\[aq]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.
.SS Is anyone going to need the feature?
.PP
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.
.SS Is your question about youtube\-dl?
.PP
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\[aq]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.
