 167
 168 CONFIGURATION
 169 =============
 170
 171 You can configure youtube-dl by placing default arguments (such as
 172 --extract-audio --no-mtime to always extract the audio and not copy the
 173 mtime) into /etc/youtube-dl.conf and/or ~/.config/youtube-dl.conf.
 174
 175 OUTPUT TEMPLATE
 176 ===============
 177
 178 The -o option allows users to indicate a template for the output file
 179 names. The basic usage is not to set any template arguments when
 180 downloading a single file, like in
 181 youtube-dl -o funny_video.flv "http://some/video". However, it may
 182 contain special sequences that will be replaced when downloading each
 183 video. The special sequences have the format %(NAME)s. To clarify, that
 184 is a percent symbol followed by a name in parenthesis, followed by a
 185 lowercase S. Allowed names are:
 186
 187 -   id: The sequence will be replaced by the video identifier.
 188 -   url: The sequence will be replaced by the video URL.
 189 -   uploader: The sequence will be replaced by the nickname of the
 190     person who uploaded the video.
 191 -   upload_date: The sequence will be replaced by the upload date in
 192     YYYYMMDD format.
 193 -   title: The sequence will be replaced by the video title.
 194 -   ext: The sequence will be replaced by the appropriate extension
 195     (like flv or mp4).
 196 -   epoch: The sequence will be replaced by the Unix epoch when creating
 197     the file.
 198 -   autonumber: The sequence will be replaced by a five-digit number
 199     that will be increased with each download, starting at zero.
 200 -   playlist: The name or the id of the playlist that contains the
 201     video.
 202 -   playlist_index: The index of the video in the playlist, a five-digit
 203     number.
 204
 205 The current default template is %(id)s.%(ext)s, but that will be
 206 switchted to %(title)s-%(id)s.%(ext)s (which can be requested with -t at
 207 the moment).
 208
 209 In some cases, you don't want special characters such as 中, spaces, or
 210 &, such as when transferring the downloaded filename to a Windows system
 211 or the filename through an 8bit-unsafe channel. In these cases, add the
 212 --restrict-filenames flag to get a shorter title:
 213
 214     $ youtube-dl --get-filename -o "%(title)s.%(ext)s" BaW_jenozKc
 215     youtube-dl test video ''_ä↭𝕐.mp4    # All kinds of weird characters
 216     $ youtube-dl --get-filename -o "%(title)s.%(ext)s" BaW_jenozKc --restrict-filenames
 217     youtube-dl_test_video_.mp4          # A simple file name
 218
 219 VIDEO SELECTION
 220 ===============
 221
 222 Videos can be filtered by their upload date using the options --date,
 223 --datebefore or --dateafter, they accept dates in two formats:
 224
 225 -   Absolute dates: Dates in the format YYYYMMDD.
 226 -   Relative dates: Dates in the format
 227     (now|today)[+-][0-9](day|week|month|year)(s)?
 228
 229 Examples:
 230
 231     $ youtube-dl --dateafter now-6months #will only download the videos uploaded in the last 6 months
 232     $ youtube-dl --date 19700101 #will only download the videos uploaded in January 1, 1970
 233     $ youtube-dl --dateafter 20000101 --datebefore 20100101 #will only download the videos uploaded between 2000 and 2010
 234
 235 FAQ
 236 ===
 237
 238 Can you please put the -b option back?
 239
 240 Most people asking this question are not aware that youtube-dl now
 241 defaults to downloading the highest available quality as reported by
 242 YouTube, which will be 1080p or 720p in some cases, so you no longer
 243 need the -b option. For some specific videos, maybe YouTube does not
 244 report them to be available in a specific high quality format you''re
 245 interested in. In that case, simply request it with the -f option and
 246 youtube-dl will try to download it.
 247
 248 I get HTTP error 402 when trying to download a video. What's this?
 249
 250 Apparently YouTube requires you to pass a CAPTCHA test if you download
 251 too much. We''re considering to provide a way to let you solve the
 252 CAPTCHA, but at the moment, your best course of action is pointing a
 253 webbrowser to the youtube URL, solving the CAPTCHA, and restart
 254 youtube-dl.
 255
 256 I have downloaded a video but how can I play it?
 257
 258 Once the video is fully downloaded, use any video player, such as vlc or
 259 mplayer.
 260
 261 The links provided by youtube-dl -g are not working anymore
 262
 263 The URLs youtube-dl outputs require the downloader to have the correct
 264 cookies. Use the --cookies option to write the required cookies into a
 265 file, and advise your downloader to read cookies from that file. Some
 266 sites also require a common user agent to be used, use --dump-user-agent
 267 to see the one in use by youtube-dl.
 268
 269 ERROR: no fmt_url_map or conn information found in video info
 270
 271 youtube has switched to a new video info format in July 2011 which is
 272 not supported by old versions of youtube-dl. You can update youtube-dl
 273 with sudo youtube-dl --update.
 274
 275 ERROR: unable to download video
 276
 277 youtube requires an additional signature since September 2012 which is
 278 not supported by old versions of youtube-dl. You can update youtube-dl
 279 with sudo youtube-dl --update.
 280
 281 SyntaxError: Non-ASCII character
 282
 283 The error
 284
 285     File "youtube-dl", line 2
 286     SyntaxError: Non-ASCII character '\x93' ...
 287
 288 means you're using an outdated version of Python. Please update to
 289 Python 2.6 or 2.7.
 290
 291 What is this binary file? Where has the code gone?
 292
 293 Since June 2012 (#342) youtube-dl is packed as an executable zipfile,
 294 simply unzip it (might need renaming to youtube-dl.zip first on some
 295 systems) or clone the git repository, as laid out above. If you modify
 296 the code, you can run it by executing the __main__.py file. To recompile
 297 the executable, run make youtube-dl.
 298
 299 The exe throws a Runtime error from Visual C++
 300
 301 To run the exe you need to install first the Microsoft Visual C++ 2008
 302 Redistributable Package.

 313 BUGS
 314 ====
 315
 316 Bugs and suggestions should be reported at:
 317 https://github.com/rg3/youtube-dl/issues
 318
 319 Please include:
 320
 321 -   Your exact command line, like
 322     youtube-dl -t "http://www.youtube.com/watch?v=uHlDtZ6Oc3s&feature=channel_video_title".
 323     A common mistake is not to escape the &. Putting URLs in quotes
 324     should solve this problem.
 325 -   If possible re-run the command with --verbose, and include the full
 326     output, it is really helpful to us.
 327 -   The output of youtube-dl --version
 328 -   The output of python --version
 329 -   The name and version of your Operating System ("Ubuntu 11.04 x64" or
 330     "Windows 7 x64" is usually enough).
