+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 (https://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

+.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]http_dash_segments\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.

+.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"

+.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 (https://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
-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).
+(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

+\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 https://example.com/video/1234567 to
+https://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.

+.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.
