 161 # CONFIGURATION
 162
 163 You can configure youtube-dl by placing default arguments (such as `--extract-audio --no-mtime` to always extract the audio and not copy the mtime) into `/etc/youtube-dl.conf` and/or `~/.config/youtube-dl.conf`.
 164
 165 # OUTPUT TEMPLATE
 166
 167 The `-o` option allows users to indicate a template for the output file names. The basic usage is not to set any template arguments when downloading a single file, like in `youtube-dl -o funny_video.flv "http://some/video"`. However, it may contain special sequences that will be replaced when downloading each video. The special sequences have the format `%(NAME)s`. To clarify, that is a percent symbol followed by a name in parenthesis, followed by a lowercase S. Allowed names are:
 168
 169  - `id`: The sequence will be replaced by the video identifier.
 170  - `url`: The sequence will be replaced by the video URL.
 171  - `uploader`: The sequence will be replaced by the nickname of the person who uploaded the video.
 172  - `upload_date`: The sequence will be replaced by the upload date in YYYYMMDD format.
 173  - `title`: The sequence will be replaced by the video title.
 174  - `ext`: The sequence will be replaced by the appropriate extension (like flv or mp4).
 175  - `epoch`: The sequence will be replaced by the Unix epoch when creating the file.
 176  - `autonumber`: The sequence will be replaced by a five-digit number that will be increased with each download, starting at zero.
 177  - `playlist`: The name or the id of the playlist that contains the video.
 178  - `playlist_index`: The index of the video in the playlist, a five-digit number.
 179
 180 The current default template is `%(title)s-%(id)s.%(ext)s`.
 181
 182 In some cases, you don't want special characters such as 中, spaces, or &, such as when transferring the downloaded filename to a Windows system or the filename through an 8bit-unsafe channel. In these cases, add the `--restrict-filenames` flag to get a shorter title:
 183
 184     $ youtube-dl --get-filename -o "%(title)s.%(ext)s" BaW_jenozKc
 185     youtube-dl test video ''_ä↭𝕐.mp4    # All kinds of weird characters
 186     $ youtube-dl --get-filename -o "%(title)s.%(ext)s" BaW_jenozKc --restrict-filenames
 187     youtube-dl_test_video_.mp4          # A simple file name
 188
 189 # VIDEO SELECTION
 190
 191 Videos can be filtered by their upload date using the options `--date`, `--datebefore` or `--dateafter`, they accept dates in two formats:
 192
 193  - Absolute dates: Dates in the format `YYYYMMDD`.
 194  - Relative dates: Dates in the format `(now|today)[+-][0-9](day|week|month|year)(s)?`
 195
 196 Examples:
 197
 198         $ youtube-dl --dateafter now-6months #will only download the videos uploaded in the last 6 months
 199         $ youtube-dl --date 19700101 #will only download the videos uploaded in January 1, 1970
 200         $ youtube-dl --dateafter 20000101 --datebefore 20100101 #will only download the videos uploaded between 2000 and 2010
 201
 202 # FAQ
 203
 204 ### Can you please put the -b option back?
 205
 206 Most people asking this question are not aware that youtube-dl now defaults to downloading the highest available quality as reported by YouTube, which will be 1080p or 720p in some cases, so you no longer need the `-b` option. For some specific videos, maybe YouTube does not report them to be available in a specific high quality format you're interested in. In that case, simply request it with the `-f` option and youtube-dl will try to download it.
 207
 208 ### I get HTTP error 402 when trying to download a video. What's this?
 209
 210 Apparently YouTube requires you to pass a CAPTCHA test if you download too much. We're [considering to provide a way to let you solve the CAPTCHA](https://github.com/rg3/youtube-dl/issues/154), but at the moment, your best course of action is pointing a webbrowser to the youtube URL, solving the CAPTCHA, and restart youtube-dl.
 211
 212 ### I have downloaded a video but how can I play it?
 213
 214 Once the video is fully downloaded, use any video player, such as [vlc](http://www.videolan.org) or [mplayer](http://www.mplayerhq.hu/).
 215
 216 ### The links provided by youtube-dl -g are not working anymore
 217
 218 The URLs youtube-dl outputs require the downloader to have the correct cookies. Use the `--cookies` option to write the required cookies into a file, and advise your downloader to read cookies from that file. Some sites also require a common user agent to be used, use `--dump-user-agent` to see the one in use by youtube-dl.
 219
 220 ### ERROR: no fmt_url_map or conn information found in video info
 221
 222 youtube has switched to a new video info format in July 2011 which is not supported by old versions of youtube-dl. You can update youtube-dl with `sudo youtube-dl --update`.
 223
 224 ### ERROR: unable to download video ###
 225
 226 youtube requires an additional signature since September 2012 which is not supported by old versions of youtube-dl. You can update youtube-dl with `sudo youtube-dl --update`.
 227
 228 ### SyntaxError: Non-ASCII character ###
 229
 230 The error
 231
 232     File "youtube-dl", line 2
 233     SyntaxError: Non-ASCII character '\x93' ...
 234
 235 means you're using an outdated version of Python. Please update to Python 2.6 or 2.7.
 236
 237 ### What is this binary file? Where has the code gone?
 238
 239 Since June 2012 (#342) youtube-dl is packed as an executable zipfile, simply unzip it (might need renaming to `youtube-dl.zip` first on some systems) or clone the git repository, as laid out above. If you modify the code, you can run it by executing the `__main__.py` file. To recompile the executable, run `make youtube-dl`.
 240
 241 ### The exe throws a *Runtime error from Visual C++*
 242
 243 To run the exe you need to install first the [Microsoft Visual C++ 2008 Redistributable Package](http://www.microsoft.com/en-us/download/details.aspx?id=29).

 251 # BUGS
 252
 253 Bugs and suggestions should be reported at: <https://github.com/rg3/youtube-dl/issues>
 254
 255 Please include:
 256
 257 * Your exact command line, like `youtube-dl -t "http://www.youtube.com/watch?v=uHlDtZ6Oc3s&feature=channel_video_title"`. A common mistake is not to escape the `&`. Putting URLs in quotes should solve this problem.
 258 * If possible re-run the command with `--verbose`, and include the full output, it is really helpful to us.
 259 * The output of `youtube-dl --version`
 260 * The output of `python --version`
 261 * The name and version of your Operating System ("Ubuntu 11.04 x64" or "Windows 7 x64" is usually enough).
