# DESCRIPTION

**youtube-dl** is a small command-line program to download videos from
8
11
YouTube.com and a few more sites. It requires the Python interpreter, version
9
12
2.x (x being at least 6), and it is not platform specific. It should work in
10
13
your Unix box, in Windows or in Mac OS X. It is released to the public domain,
11
14
which means you can modify it, redistribute it or use it however you like.

# CONFIGURATION
116
+
117
+
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 `~/.local/config/youtube-dl.conf`.
118
+
119
+
# OUTPUT TEMPLATE
120
+
121
+
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:
122
+
123
+
-`id`: The sequence will be replaced by the video identifier.
124
+
-`url`: The sequence will be replaced by the video URL.
125
+
-`uploader`: The sequence will be replaced by the nickname of the person who uploaded the video.
126
+
-`upload_date`: The sequence will be replaced by the upload date in YYYYMMDD format.
127
+
-`title`: The sequence will be replaced by the video title.
128
+
-`ext`: The sequence will be replaced by the appropriate extension (like flv or mp4).
129
+
-`epoch`: The sequence will be replaced by the Unix epoch when creating the file.
130
+
-`autonumber`: The sequence will be replaced by a five-digit number that will be increased with each download, starting at zero.
131
+
132
+
The current default template is `%(id)s.%(ext)s`, but that will be switchted to `%(title)s-%(id)s.%(ext)s` (which can be requested with `-t` at the moment).
133
+
134
+
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:

### What is this binary file? Where has the code gone?
177
+
178
+
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`.

+
### The exe throws a *Runtime error from Visual C++*
181
+
182
+
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).
