  11 DESCRIPTION
  12 ===========
  13
  14 youtube-dl is a small command-line program to download videos from
  15 YouTube.com and a few more sites. It requires the Python interpreter,
  16 version 2.6, 2.7, or 3.3+, and it is not platform specific. It should
  17 work on your Unix box, on Windows or on Mac OS X. It is released to the
  18 public domain, which means you can modify it, redistribute it or use it
  19 however you like.

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

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