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

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

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

 357 A common mistake is not to escape the \f[C]&\f[].
