+.SH FORMAT SELECTION
+.PP
+By default youtube\-dl tries to download the best quality, but sometimes
+you may want to download in a different format.
+The simplest case is requesting a specific format, for example
+\f[C]\-f\ 22\f[].
+You can get the list of available formats using
+\f[C]\-\-list\-formats\f[], you can also use a file extension (currently
+it supports aac, m4a, mp3, mp4, ogg, wav, webm) or the special names
+\f[C]best\f[], \f[C]bestvideo\f[], \f[C]bestaudio\f[] and
+\f[C]worst\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, as in \f[C]\-f\ 22/17/18\f[].
+You can also filter the video results by putting a condition in
+brackets, as in \f[C]\-f\ "best[height=720]"\f[] (or
+\f[C]\-f\ "[filesize>10M]"\f[]).
+This works for filesize, height, width, tbr, abr, vbr, asr, and fps and
+the comparisons <, <=, >, >=, =, != and for ext, acodec, vcodec,
+container, and protocol and the comparisons =, != .
+Formats for which the value is not known are excluded unless you put a
+question mark (?) 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.
+Use commas to download multiple formats, such as
+\f[C]\-f\ 136/137/mp4/bestvideo,140/m4a/bestaudio\f[].
+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), for example \f[C]\-f\ bestvideo+bestaudio\f[].
+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.

-The URLs youtube\-dl outputs require the downloader to have the correct

+Passing cookies to youtube\-dl is a good way to workaround login when a

+.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

+.SH BUGS
+.PP
+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.

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

+.PP
+\f[B]Please include the full output of youtube\-dl when run with
+\f[C]\-v\f[]\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 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.
+.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
+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 \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 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.
+.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.
