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

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

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

 348 \f[C]youtube\-dl\ \-t\ "http://www.youtube.com/watch?v=uHlDtZ6Oc3s&feature=channel_video_title"\f[].
 349 A common mistake is not to escape the \f[C]&\f[].
 350 Putting URLs in quotes should solve this problem.
