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

 285 .SH FAQ
 286 .SS Can you please put the \-b option back?
 287 .PP
 288 Most people asking this question are not aware that youtube\-dl now
 289 defaults to downloading the highest available quality as reported by
 290 YouTube, which will be 1080p or 720p in some cases, so you no longer
 291 need the \f[C]\-b\f[] option.
 292 For some specific videos, maybe YouTube does not report them to be
 293 available in a specific high quality format you\[aq]re interested in.
 294 In that case, simply request it with the \f[C]\-f\f[] option and
 295 youtube\-dl will try to download it.
 296 .SS I get HTTP error 402 when trying to download a video. What\[aq]s
 297 this?
 298 .PP
 299 Apparently YouTube requires you to pass a CAPTCHA test if you download
 300 too much.
 301 We\[aq]re considering to provide a way to let you solve the
 302 CAPTCHA (https://github.com/rg3/youtube-dl/issues/154), but at the
 303 moment, your best course of action is pointing a webbrowser to the
 304 youtube URL, solving the CAPTCHA, and restart youtube\-dl.
 305 .SS I have downloaded a video but how can I play it?
 306 .PP
 307 Once the video is fully downloaded, use any video player, such as
 308 vlc (http://www.videolan.org) or mplayer (http://www.mplayerhq.hu/).
 309 .SS The links provided by youtube\-dl \-g are not working anymore
 310 .PP
 311 The URLs youtube\-dl outputs require the downloader to have the correct
 312 cookies.

 342 Since June 2012 (#342) youtube\-dl is packed as an executable zipfile,
 343 simply unzip it (might need renaming to \f[C]youtube\-dl.zip\f[] first
 344 on some systems) or clone the git repository, as laid out above.
 345 If you modify the code, you can run it by executing the
 346 \f[C]__main__.py\f[] file.
 347 To recompile the executable, run \f[C]make\ youtube\-dl\f[].
