# NAME

||
youtube-dl
|
||
|
||
# SYNOPSIS
|
||
**youtube-dl** [OPTIONS] URL [URL...]
|
||
|
||
# DESCRIPTION
|
||
**youtube-dl** is a small command-line program to download videos from
|
||
YouTube.com and a few more sites. It requires the Python interpreter, version
|
||
2.6, 2.7, or 3.3+, and it is not platform specific. It should work on
|
||
your Unix box, on Windows or on Mac OS X. It is released to the public domain,
|
||
which means you can modify it, redistribute it or use it however you like.

# CONFIGURATION
|
||
|
||
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`.
|
||
|
||
# OUTPUT TEMPLATE
|
||
|
||
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:
|
||
|
||
- `id`: The sequence will be replaced by the video identifier.
|
||
- `url`: The sequence will be replaced by the video URL.
|
||
- `uploader`: The sequence will be replaced by the nickname of the person who uploaded the video.
|
||
- `upload_date`: The sequence will be replaced by the upload date in YYYYMMDD format.
|
||
- `title`: The sequence will be replaced by the video title.
|
||
- `ext`: The sequence will be replaced by the appropriate extension (like flv or mp4).
|
||
- `epoch`: The sequence will be replaced by the Unix epoch when creating the file.
|
||
- `autonumber`: The sequence will be replaced by a five-digit number that will be increased with each download, starting at zero.
|
||
|
||
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).
|
||
|
||
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:
|
||
|
||
$ youtube-dl --get-filename -o "%(title)s.%(ext)s" BaW_jenozKc
|
||
youtube-dl test video ''_ä↭𝕐.mp4 # All kinds of weird characters
|
||
$ youtube-dl --get-filename -o "%(title)s.%(ext)s" BaW_jenozKc --restrict-filenames
|
||
youtube-dl_test_video_.mp4 # A simple file name
|
||
|
||
# FAQ
|
||
|
||
### Can you please put the -b option back?
|
||
|
||
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.
|
||
|
||
### I get HTTP error 402 when trying to download a video. What's this?
|
||
|
||
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.
|
||
|
||
### I have downloaded a video but how can I play it?
|
||
|
||
Once the video is fully downloaded, use any video player, such as [vlc](http://www.videolan.org) or [mplayer](http://www.mplayerhq.hu/).
|
||
|
||
### The links provided by youtube-dl -g are not working anymore
|
||
|
||
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.
|
||
|
||
### ERROR: no fmt_url_map or conn information found in video info
|
||
|
||
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`.
|
||
|
||
### ERROR: unable to download video ###
|
||
|
||
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`.
|
||
|
||
### SyntaxError: Non-ASCII character ###
|
||
|
||
The error
|
||
|
||
File "youtube-dl", line 2
|
||
SyntaxError: Non-ASCII character '\x93' ...
|
||
|
||
means you're using an outdated version of Python. Please update to Python 2.6 or 2.7.
|
||
|
||
### What is this binary file? Where has the code gone?
|
||
|
||
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++*
|
||
|
||
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).

# BUGS
|
||
|
||
Bugs and suggestions should be reported at: <https://github.com/rg3/youtube-dl/issues>
|
||
|
||
Please include:
|
||
|
||
* 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.
|
||
* If possible re-run the command with `--verbose`, and include the full output, it is really helpful to us.
|
||
* The output of `youtube-dl --version`
|
||
* The output of `python --version`
|
||
* The name and version of your Operating System ("Ubuntu 11.04 x64" or "Windows 7 x64" is usually enough).
