 178 .SH CONFIGURATION
 179 .PP
 180 You can configure youtube\-dl by placing default arguments (such as
 181 \f[C]\-\-extract\-audio\ \-\-no\-mtime\f[] to always extract the audio
 182 and not copy the mtime) into \f[C]/etc/youtube\-dl.conf\f[] and/or
 183 \f[C]~/.config/youtube\-dl.conf\f[].
 184 .SH OUTPUT TEMPLATE
 185 .PP
 186 The \f[C]\-o\f[] option allows users to indicate a template for the
 187 output file names.
 188 The basic usage is not to set any template arguments when downloading a
 189 single file, like in
 190 \f[C]youtube\-dl\ \-o\ funny_video.flv\ "http://some/video"\f[].
 191 However, it may contain special sequences that will be replaced when
 192 downloading each video.
 193 The special sequences have the format \f[C]%(NAME)s\f[].
 194 To clarify, that is a percent symbol followed by a name in parenthesis,
 195 followed by a lowercase S.
 196 Allowed names are:
 197 .IP \[bu] 2
 198 \f[C]id\f[]: The sequence will be replaced by the video identifier.
 199 .IP \[bu] 2
 200 \f[C]url\f[]: The sequence will be replaced by the video URL.
 201 .IP \[bu] 2
 202 \f[C]uploader\f[]: The sequence will be replaced by the nickname of the
 203 person who uploaded the video.
 204 .IP \[bu] 2
 205 \f[C]upload_date\f[]: The sequence will be replaced by the upload date
 206 in YYYYMMDD format.
 207 .IP \[bu] 2
 208 \f[C]title\f[]: The sequence will be replaced by the video title.
 209 .IP \[bu] 2
 210 \f[C]ext\f[]: The sequence will be replaced by the appropriate extension
 211 (like flv or mp4).
 212 .IP \[bu] 2
 213 \f[C]epoch\f[]: The sequence will be replaced by the Unix epoch when
 214 creating the file.
 215 .IP \[bu] 2
 216 \f[C]autonumber\f[]: The sequence will be replaced by a five\-digit
 217 number that will be increased with each download, starting at zero.
 218 .IP \[bu] 2
 219 \f[C]playlist\f[]: The name or the id of the playlist that contains the
 220 video.
 221 .IP \[bu] 2
 222 \f[C]playlist_index\f[]: The index of the video in the playlist, a
 223 five\-digit number.
 224 .PP
 225 The current default template is \f[C]%(id)s.%(ext)s\f[], but that will
 226 be switchted to \f[C]%(title)s\-%(id)s.%(ext)s\f[] (which can be
 227 requested with \f[C]\-t\f[] at the moment).
 228 .PP
 229 In some cases, you don\[aq]t want special characters such as 中, spaces,
 230 or &, such as when transferring the downloaded filename to a Windows
 231 system or the filename through an 8bit\-unsafe channel.
 232 In these cases, add the \f[C]\-\-restrict\-filenames\f[] flag to get a
 233 shorter title:
 234 .IP
 235 .nf
 236 \f[C]
 237 $\ youtube\-dl\ \-\-get\-filename\ \-o\ "%(title)s.%(ext)s"\ BaW_jenozKc

 263 .SH FAQ
 264 .SS Can you please put the \-b option back?
 265 .PP
 266 Most people asking this question are not aware that youtube\-dl now
 267 defaults to downloading the highest available quality as reported by
 268 YouTube, which will be 1080p or 720p in some cases, so you no longer
 269 need the \-b option.
 270 For some specific videos, maybe YouTube does not report them to be
 271 available in a specific high quality format you\[aq]\[aq]re interested
 272 in.
 273 In that case, simply request it with the \-f option and youtube\-dl will
 274 try to download it.
 275 .SS I get HTTP error 402 when trying to download a video. What\[aq]s
 276 this?
 277 .PP
 278 Apparently YouTube requires you to pass a CAPTCHA test if you download
 279 too much.
 280 We\[aq]\[aq]re considering to provide a way to let you solve the
 281 CAPTCHA (https://github.com/rg3/youtube-dl/issues/154), but at the
 282 moment, your best course of action is pointing a webbrowser to the
 283 youtube URL, solving the CAPTCHA, and restart youtube\-dl.
 284 .SS I have downloaded a video but how can I play it?
 285 .PP
 286 Once the video is fully downloaded, use any video player, such as
 287 vlc (http://www.videolan.org) or mplayer (http://www.mplayerhq.hu/).
 288 .SS The links provided by youtube\-dl \-g are not working anymore
 289 .PP
 290 The URLs youtube\-dl outputs require the downloader to have the correct
 291 cookies.
 292 Use the \f[C]\-\-cookies\f[] option to write the required cookies into a
 293 file, and advise your downloader to read cookies from that file.
 294 Some sites also require a common user agent to be used, use
 295 \f[C]\-\-dump\-user\-agent\f[] to see the one in use by youtube\-dl.

 321 Since June 2012 (#342) youtube\-dl is packed as an executable zipfile,
 322 simply unzip it (might need renaming to \f[C]youtube\-dl.zip\f[] first
 323 on some systems) or clone the git repository, as laid out above.
 324 If you modify the code, you can run it by executing the
 325 \f[C]__main__.py\f[] file.
 326 To recompile the executable, run \f[C]make\ youtube\-dl\f[].
 327 .SS The exe throws a \f[I]Runtime error from Visual C++\f[]
 328 .PP
 329 To run the exe you need to install first the Microsoft Visual C++ 2008
 330 Redistributable
 331 Package (http://www.microsoft.com/en-us/download/details.aspx?id=29).

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