+You can configure youtube\-dl by placing any supported command line
+option to a configuration file.
+On Linux and OS X, 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[].
+Note that by default configuration file may not exist so you may need to
+create it yourself.
+.PP
+For example, with the following configuration file youtube\-dl will
+always extract the audio, not copy the mtime, use a proxy and save all
+videos under \f[C]Movies\f[] directory in your home directory:
+.IP

+.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 a 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 only you:
+.IP
+.nf
+\f[C]
+touch\ $HOME/.netrc
+chmod\ a\-rwx,u+rw\ $HOME/.netrc
+\f[]
+.fi
+.PP
+After that you can add credentials for an extractor in the following
+format, where \f[I]extractor\f[] is the name of the 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

+.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
+\f[B]tl;dr:\f[] navigate me to examples (#format-selection-examples).
+.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 the best quality
+format of a particular file extension served as a single file, e.g.
+\f[C]\-f\ webm\f[] will download the best quality format with the
+\f[C]webm\f[] extension served as a single file.
+.PP
+You can also use special names to select particular edge case formats:
+\- \f[C]best\f[]: Select the best quality format represented by a single
+file with video and audio.
+\- \f[C]worst\f[]: Select the worst quality format represented by a
+single file with video and audio.
+\- \f[C]bestvideo\f[]: Select the best quality video\-only format (e.g.
+DASH video).
+May not be available.
+\- \f[C]worstvideo\f[]: Select the worst quality video\-only format.
+May not be available.
+\- \f[C]bestaudio\f[]: Select the best quality audio only\-format.
+May not be available.
+\- \f[C]worstaudio\f[]: Select the worst quality audio only\-format.
+May not be available.
+.PP
+For example, to download the 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 a 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 a more sophisticated example combined with the 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]mms\f[], \f[C]f4m\f[], \f[C]ism\f[], \f[C]m3u8\f[],
+or \f[C]m3u8_native\f[]) \- \f[C]format_id\f[]: A short description of
+the format
+.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 the 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 the best video\-only format, the 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 the default format selection
+(see #5447 (https://github.com/rg3/youtube-dl/issues/5447),
+#5456 (https://github.com/rg3/youtube-dl/issues/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.

+.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

+.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
+people (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 I\[aq]m getting an error when trying to use output template:
+\f[C]error:\ using\ output\ template\ conflicts\ with\ using\ title,\ video\ ID\ or\ auto\ number\f[]
+.PP
+Make sure you are not using \f[C]\-o\f[] with any of these options
+\f[C]\-t\f[], \f[C]\-\-title\f[], \f[C]\-\-id\f[], \f[C]\-A\f[] or
+\f[C]\-\-auto\-number\f[] set in command line or in a configuration
+file.
+Remove the latter if any.
+.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 web browser 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
+mpv (https://mpv.io/), 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 web browser.
+.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 and/or HTTP headers.
+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.
+You can also get necessary cookies and HTTP headers from JSON output
+obtained with \f[C]\-\-dump\-json\f[].
+.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.
+.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.
+See above (#how-do-i-update-youtube-dl) for how to update youtube\-dl.
+.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.
+See above (#how-do-i-update-youtube-dl) for how to update youtube\-dl.
+.SS Video URL contains an ampersand and I\[aq]m getting some strange
+output \f[C][1]\ 2839\f[] or
+\f[C]\[aq]v\[aq]\ is\ not\ recognized\ as\ an\ internal\ or\ external\ command\f[]
+.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[]
+.PP
+For Windows you have to use the double quotes:
+.PP
+\f[C]youtube\-dl\ "https://www.youtube.com/watch?t=4&v=BaW_jenozKc"\f[]
+.SS ExtractorError: Could not find JS function u\[aq]OF\[aq]

+.SS HTTP Error 429: Too Many Requests or 402: Payment Required
+.PP
+These two error codes indicate that the service is blocking your IP

+Contact the service and ask them to unblock your IP address, or \- if
+you have acquired a whitelisted IP address already \- use the
+\f[C]\-\-proxy\f[] or \f[C]\-\-source\-address\f[]

+.fi
+.PP
+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 (https://github.com/rg3/youtube-dl/issues/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 an error due to missing \f[C]MSVCR100.dll\f[]
+.PP
+To run the exe you need to install first the Microsoft Visual C++ 2010
+Redistributable Package
+(x86) (https://www.microsoft.com/en-US/download/details.aspx?id=5555).
+.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[].
+.PP
+In order to extract cookies from browser use any conforming browser
+extension for exporting cookies.
+For example,
+cookies.txt (https://chrome.google.com/webstore/detail/cookiestxt/njabckikapfpffapmjgojcnbfjonfjfg)
+(for Chrome) or Export
+Cookies (https://addons.mozilla.org/en-US/firefox/addon/export-cookies/)
+(for Firefox).
+.PP
+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 and \f[C]LF\f[]
+(\f[C]\\n\f[]) for Unix and Unix\-like systems (Linux, Mac OS, etc.).
+\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 How do I stream directly to media player?
+.PP
+You will first need to tell youtube\-dl to stream media to stdout with
+\f[C]\-o\ \-\f[], and also tell your media player to read from stdin (it
+must be capable of this for streaming) and then pipe former to latter.
+For example, streaming to vlc (http://www.videolan.org/) can be achieved
+with:
+.IP
+.nf
+\f[C]
+youtube\-dl\ \-o\ \-\ "http://www.youtube.com/watch?v=BaW_jenozKcj"\ |\ vlc\ \-
+\f[]
+.fi
+.SS How do I download only new videos from a playlist?
+.PP
+Use download\-archive feature.
+With this feature you should initially download the complete playlist
+with \f[C]\-\-download\-archive\ /path/to/download/archive/file.txt\f[]
+that will record identifiers of all the videos in a special file.
+Each subsequent run with the same \f[C]\-\-download\-archive\f[] will
+download only new videos and skip all videos that have been downloaded
+before.
+Note that only successful downloads are recorded in the file.
+.PP
+For example, at first,
+.IP
+.nf
+\f[C]
+youtube\-dl\ \-\-download\-archive\ archive.txt\ "https://www.youtube.com/playlist?list=PLwiyx1dc3P2JR9N8gQaQN_BCvlSlap7re"
+\f[]
+.fi
+.PP
+will download the complete \f[C]PLwiyx1dc3P2JR9N8gQaQN_BCvlSlap7re\f[]
+playlist and create a file \f[C]archive.txt\f[].
+Each subsequent run will only download new videos if any:
+.IP
+.nf
+\f[C]
+youtube\-dl\ \-\-download\-archive\ archive.txt\ "https://www.youtube.com/playlist?list=PLwiyx1dc3P2JR9N8gQaQN_BCvlSlap7re"
+\f[]
+.fi
+.SS Should I add \f[C]\-\-hls\-prefer\-native\f[] into my config?
+.PP
+When youtube\-dl detects an HLS video, it can download it either with
+the built\-in downloader or ffmpeg.
+Since many HLS streams are slightly invalid and ffmpeg/youtube\-dl each
+handle some invalid cases better than the other, there is an option to
+switch the downloader if needed.
+.PP
+When youtube\-dl knows that one particular downloader works better for a
+given website, that downloader will be picked.
+Otherwise, youtube\-dl will pick the best downloader for general
+compatibility, which at the moment happens to be ffmpeg.
+This choice may change in future versions of youtube\-dl, with
+improvements of the built\-in downloader and/or ffmpeg.
+.PP
+In particular, the generic extractor (used when your website is not in
+the list of supported sites by
+youtube\-dl (http://rg3.github.io/youtube-dl/supportedsites.html) cannot
+mandate one specific downloader.
+.PP
+If you put either \f[C]\-\-hls\-prefer\-native\f[] or
+\f[C]\-\-hls\-prefer\-ffmpeg\f[] into your configuration, a different
+subset of videos will fail to download correctly.
+Instead, it is much better to file an issue (https://yt-dl.org/bug) or a
+pull request which details why the native or the ffmpeg HLS downloader
+is a better choice for your use case.
+.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 Why do I need to go through that much red tape when filing bugs?
+.PP
+Before we had the issue template, despite our extensive bug reporting
+instructions (#bugs), about 80% of the issue reports we got were
+useless, for instance because people used ancient versions hundreds of
+releases old, because of simple syntactic errors (not in youtube\-dl but
+in general shell usage), because the problem was already reported
+multiple times before, because people did not actually read an error
+message, even if it said "please install ffmpeg", because people did not
+mention the URL they were trying to download and many more simple,
+easy\-to\-avoid problems, many of whom were totally unrelated to
+youtube\-dl.
+.PP
+youtube\-dl is an open\-source project manned by too few volunteers, so
+we\[aq]d rather spend time fixing bugs where we are certain none of
+those simple problems apply, and where we can be reasonably confident to
+be able to reproduce the issue without asking the reporter repeatedly.
+As such, the output of \f[C]youtube\-dl\ \-v\ YOUR_URL_HERE\f[] is
+really all that\[aq]s required to file an issue.
+The issue template also guides you through some basic steps you can do,
+such as checking that your version of youtube\-dl is current.
+.SH DEVELOPER INSTRUCTIONS

+.SS youtube\-dl coding conventions
+.PP
+This section introduces a guide lines for writing idiomatic, robust and
+future\-proof extractor code.
+.PP
+Extractors are very fragile by nature since they depend on the layout of
+the source data provided by 3rd party media hosters out of your control
+and this layout tends to change.
+As an extractor implementer your task is not only to write code that
+will extract media links and metadata correctly but also to minimize
+dependency on the source\[aq]s layout and even to make the code foresee
+potential future changes and be ready for that.
+This is important because it will allow the extractor not to break on
+minor layout changes thus keeping old youtube\-dl versions working.
+Even though this breakage issue is easily fixed by emitting a new
+version of youtube\-dl with a fix incorporated, all the previous
+versions become broken in all repositories and distros\[aq] packages
+that may not be so prompt in fetching the update from us.
+Needless to say, some non rolling release distros may never receive an
+update at all.
+.SS Mandatory and optional metafields
+.PP
+For extraction to work youtube\-dl relies on metadata your extractor
+extracts and provides to youtube\-dl expressed by an information
+dictionary (https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/common.py#L75-L257)
+or simply \f[I]info dict\f[].
+Only the following meta fields in the \f[I]info dict\f[] are considered
+mandatory for a successful extraction process by youtube\-dl:
+.IP \[bu] 2
+\f[C]id\f[] (media identifier)
+.IP \[bu] 2
+\f[C]title\f[] (media title)
+.IP \[bu] 2
+\f[C]url\f[] (media download URL) or \f[C]formats\f[]
+.PP
+In fact only the last option is technically mandatory (i.e.
+if you can\[aq]t figure out the download location of the media the
+extraction does not make any sense).
+But by convention youtube\-dl also treats \f[C]id\f[] and \f[C]title\f[]
+as mandatory.
+Thus the aforementioned metafields are the critical data that the
+extraction does not make any sense without and if any of them fail to be
+extracted then the extractor is considered completely broken.
+.PP
+Any
+field (https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/common.py#L149-L257)
+apart from the aforementioned ones are considered \f[B]optional\f[].
+That means that extraction should be \f[B]tolerant\f[] to situations
+when sources for these fields can potentially be unavailable (even if
+they are always available at the moment) and \f[B]future\-proof\f[] in
+order not to break the extraction of general purpose mandatory fields.
+.SS Example
+.PP
+Say you have some source dictionary \f[C]meta\f[] that you\[aq]ve
+fetched as JSON with HTTP request and it has a key \f[C]summary\f[]:
+.IP
+.nf
+\f[C]
+meta\ =\ self._download_json(url,\ video_id)
+\f[]
+.fi
+.PP
+Assume at this point \f[C]meta\f[]\[aq]s layout is:
+.IP
+.nf
+\f[C]
+{
+\ \ \ \ ...
+\ \ \ \ "summary":\ "some\ fancy\ summary\ text",
+\ \ \ \ ...
+}
+\f[]
+.fi
+.PP
+Assume you want to extract \f[C]summary\f[] and put it into the
+resulting info dict as \f[C]description\f[].
+Since \f[C]description\f[] is an optional meta field you should be ready
+that this key may be missing from the \f[C]meta\f[] dict, so that you
+should extract it like:
+.IP
+.nf
+\f[C]
+description\ =\ meta.get(\[aq]summary\[aq])\ \ #\ correct
+\f[]
+.fi
+.PP
+and not like:
+.IP
+.nf
+\f[C]
+description\ =\ meta[\[aq]summary\[aq]]\ \ #\ incorrect
+\f[]
+.fi
+.PP
+The latter will break extraction process with \f[C]KeyError\f[] if
+\f[C]summary\f[] disappears from \f[C]meta\f[] at some later time but
+with the former approach extraction will just go ahead with
+\f[C]description\f[] set to \f[C]None\f[] which is perfectly fine
+(remember \f[C]None\f[] is equivalent to the absence of data).
+.PP
+Similarly, you should pass \f[C]fatal=False\f[] when extracting optional
+data from a webpage with \f[C]_search_regex\f[],
+\f[C]_html_search_regex\f[] or similar methods, for instance:
+.IP
+.nf
+\f[C]
+description\ =\ self._search_regex(
+\ \ \ \ r\[aq]<span[^>]+id="title"[^>]*>([^<]+)<\[aq],
+\ \ \ \ webpage,\ \[aq]description\[aq],\ fatal=False)
+\f[]
+.fi
+.PP
+With \f[C]fatal\f[] set to \f[C]False\f[] if \f[C]_search_regex\f[]
+fails to extract \f[C]description\f[] it will emit a warning and
+continue extraction.
+.PP
+You can also pass \f[C]default=<some\ fallback\ value>\f[], for example:
+.IP
+.nf
+\f[C]
+description\ =\ self._search_regex(
+\ \ \ \ r\[aq]<span[^>]+id="title"[^>]*>([^<]+)<\[aq],
+\ \ \ \ webpage,\ \[aq]description\[aq],\ default=None)
+\f[]
+.fi
+.PP
+On failure this code will silently continue the extraction with
+\f[C]description\f[] set to \f[C]None\f[].
+That is useful for metafields that may or may not be present.
+.SS Provide fallbacks
+.PP
+When extracting metadata try to do so from multiple sources.
+For example if \f[C]title\f[] is present in several places, try
+extracting from at least some of them.
+This makes it more future\-proof in case some of the sources become
+unavailable.
+.SS Example
+.PP
+Say \f[C]meta\f[] from the previous example has a \f[C]title\f[] and you
+are about to extract it.
+Since \f[C]title\f[] is a mandatory meta field you should end up with
+something like:
+.IP
+.nf
+\f[C]
+title\ =\ meta[\[aq]title\[aq]]
+\f[]
+.fi
+.PP
+If \f[C]title\f[] disappears from \f[C]meta\f[] in future due to some
+changes on the hoster\[aq]s side the extraction would fail since
+\f[C]title\f[] is mandatory.
+That\[aq]s expected.
+.PP
+Assume that you have some another source you can extract \f[C]title\f[]
+from, for example \f[C]og:title\f[] HTML meta of a \f[C]webpage\f[].
+In this case you can provide a fallback scenario:
+.IP
+.nf
+\f[C]
+title\ =\ meta.get(\[aq]title\[aq])\ or\ self._og_search_title(webpage)
+\f[]
+.fi
+.PP
+This code will try to extract from \f[C]meta\f[] first and if it fails
+it will try extracting \f[C]og:title\f[] from a \f[C]webpage\f[].
+.SS Make regular expressions flexible
+.PP
+When using regular expressions try to write them fuzzy and flexible.
+.SS Example
+.PP
+Say you need to extract \f[C]title\f[] from the following HTML code:
+.IP
+.nf
+\f[C]
+<span\ style="position:\ absolute;\ left:\ 910px;\ width:\ 90px;\ float:\ right;\ z\-index:\ 9999;"\ class="title">some\ fancy\ title</span>
+\f[]
+.fi
+.PP
+The code for that task should look similar to:
+.IP
+.nf
+\f[C]
+title\ =\ self._search_regex(
+\ \ \ \ r\[aq]<span[^>]+class="title"[^>]*>([^<]+)\[aq],\ webpage,\ \[aq]title\[aq])
+\f[]
+.fi
+.PP
+Or even better:
+.IP
+.nf
+\f[C]
+title\ =\ self._search_regex(
+\ \ \ \ r\[aq]<span[^>]+class=(["\\\[aq]])title\\1[^>]*>(?P<title>[^<]+)\[aq],
+\ \ \ \ webpage,\ \[aq]title\[aq],\ group=\[aq]title\[aq])
+\f[]
+.fi
+.PP
+Note how you tolerate potential changes in the \f[C]style\f[]
+attribute\[aq]s value or switch from using double quotes to single for
+\f[C]class\f[] attribute:
+.PP
+The code definitely should not look like:
+.IP
+.nf
+\f[C]
+title\ =\ self._search_regex(
+\ \ \ \ r\[aq]<span\ style="position:\ absolute;\ left:\ 910px;\ width:\ 90px;\ float:\ right;\ z\-index:\ 9999;"\ class="title">(.*?)</span>\[aq],
+\ \ \ \ webpage,\ \[aq]title\[aq],\ group=\[aq]title\[aq])
+\f[]
+.fi
+.SS Use safe conversion functions
+.PP
+Wrap all extracted numeric data into safe functions from \f[C]utils\f[]:
+\f[C]int_or_none\f[], \f[C]float_or_none\f[].
+Use them for string to number conversions as well.
+.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 options available, have a look at
+\f[C]youtube_dl/YoutubeDL.py\f[] (https://github.com/rg3/youtube-dl/blob/master/youtube_dl/YoutubeDL.py#L129-L279).
+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):
+\ \ \ \ \ \ \ \ pass

+\ \ \ \ def\ warning(self,\ msg):
+\ \ \ \ \ \ \ \ pass
+
+\ \ \ \ def\ error(self,\ msg):
+\ \ \ \ \ \ \ \ print(msg)
+
+
+def\ my_hook(d):
+\ \ \ \ if\ d[\[aq]status\[aq]]\ ==\ \[aq]finished\[aq]:
+\ \ \ \ \ \ \ \ print(\[aq]Done\ downloading,\ now\ converting\ ...\[aq])
+
+
+ydl_opts\ =\ {

+\f[B]Do not post screenshots of verbose logs; only plain text is
+acceptable.\f[]
+.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#options).
+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, White house 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.
