# 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
which means you can modify it, redistribute it or use it however you like.
# OPTIONS
- -h, --help print this help text and exit
- --version print program version and exit
- -U, --update update this program to latest version. Make sure
- that you have sufficient permissions (run with
- sudo if needed)
- -i, --ignore-errors continue on download errors, for example to to
- skip unavailable videos in a playlist
- --abort-on-error Abort downloading of further videos (in the
- playlist or the command line) if an error occurs
- --dump-user-agent display the current browser identification
- --user-agent UA specify a custom user agent
- --referer REF specify a custom referer, use if the video access
- is restricted to one domain
- --list-extractors List all supported extractors and the URLs they
- would handle
- --extractor-descriptions Output descriptions of all supported extractors
- --proxy URL Use the specified HTTP/HTTPS proxy. Pass in an
- empty string (--proxy "") for direct connection
- --no-check-certificate Suppress HTTPS certificate validation.
- --cache-dir DIR Location in the filesystem where youtube-dl can
- store downloaded information permanently. By
- default $XDG_CACHE_HOME/youtube-dl or ~/.cache
- /youtube-dl .
- --no-cache-dir Disable filesystem caching
- --bidi-workaround Work around terminals that lack bidirectional
- text support. Requires fribidi executable in PATH

+ access is restricted to one domain
+ --add-header FIELD:VALUE specify a custom HTTP header and its value,

+ connection
+ --no-check-certificate Suppress HTTPS certificate validation.
+ --prefer-insecure Use an unencrypted connection to retrieve
+ information about the video. (Currently
+ supported only for YouTube)
+ --cache-dir DIR Location in the filesystem where youtube-dl
+ can store some downloaded information

+ --socket-timeout None Time to wait before giving up, in seconds
+ --bidi-workaround Work around terminals that lack
+ bidirectional text support. Requires bidiv
+ or fribidi executable in PATH

+ from google videos for youtube-dl "large
+ apple". Use the value "auto" to let
+ youtube-dl guess. The default value "error"
+ just throws an error.
+ --ignore-config Do not read configuration files. When given
+ in the global configuration file /etc
+ /youtube-dl.conf: do not read the user
+ configuration in ~/.config/youtube-dl.conf
+ (%APPDATA%/youtube-dl/config.txt on

# 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`. On Windows, the configuration file locations are `%APPDATA%\youtube-dl\config.txt` and `C:\Users\<Yourname>\youtube-dl.conf`.

+# DEVELOPER INSTRUCTIONS
-youtube-dl is released into the public domain by the copyright holders.
+Most users do not need to build youtube-dl and can [download the builds](http://rg3.github.io/youtube-dl/download.html) or get them from their distribution.
-This README file was originally written by Daniel Bolton (<https://github.com/dbbolton>) and is likewise released into the public domain.
+To run youtube-dl as a developer, you don't need to build anything either. Simply execute

+
+### Adding support for a new site
+
+If you want to add support for a new site, you can follow this quick list (assuming your service is called `yourextractor`):
+
+1. [Fork this repository](https://github.com/rg3/youtube-dl/fork)
+2. Check out the source code with `git clone git@github.com:YOUR_GITHUB_USERNAME/youtube-dl.git`
+3. Start a new git branch with `cd youtube-dl; git checkout -b yourextractor`
+4. Start with this simple template and save it to `youtube_dl/extractor/yourextractor.py`:
+
+ # coding: utf-8
+ from __future__ import unicode_literals
+
+ import re
+
+ from .common import InfoExtractor
+
+
+ class YourExtractorIE(InfoExtractor):
+ _VALID_URL = r'https?://(?:www\.)?yourextractor\.com/watch/(?P<id>[0-9]+)'
+ _TEST = {
+ 'url': 'http://yourextractor.com/watch/42',
+ 'md5': 'TODO: md5 sum of the first 10KiB of the video file',
+ 'info_dict': {
+ 'id': '42',
+ 'ext': 'mp4',
+ 'title': 'Video title goes here',
+ # TODO more properties, either as:
+ # * A value
+ # * MD5 checksum; start the string with md5:
+ # * A regular expression; start the string with re:
+ # * Any Python type (for example int or float)
+ }
+ }
+
+ def _real_extract(self, url):
+ mobj = re.match(self._VALID_URL, url)
+ video_id = mobj.group('id')
+
+ # TODO more code goes here, for example ...
+ webpage = self._download_webpage(url, video_id)
+ title = self._html_search_regex(r'<h1>(.*?)</h1>', webpage, 'title')
+
+ return {
+ 'id': video_id,
+ 'title': title,
+ # TODO more properties (see youtube_dl/extractor/common.py)
+ }
+
+
+5. Add an import in [`youtube_dl/extractor/__init__.py`](https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/__init__.py).
+6. Run `python test/test_download.py TestDownload.test_YourExtractor`. This *should fail* at first, but you can continually re-run it until you're done.
+7. Have a look at [`youtube_dl/common/extractor/common.py`](https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/common.py) for possible helper methods and a [detailed description of what your extractor should return](https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/common.py#L38). Add tests and code for as many as you want.
+8. If you can, check the code with [pyflakes](https://pypi.python.org/pypi/pyflakes) (a good idea) and [pep8](https://pypi.python.org/pypi/pep8) (optional, ignore E501).
+9. When the tests pass, [add](https://www.kernel.org/pub/software/scm/git/docs/git-add.html) the new files and [commit](https://www.kernel.org/pub/software/scm/git/docs/git-commit.html) them and [push](https://www.kernel.org/pub/software/scm/git/docs/git-push.html) the result, like this:
+
+ $ git add youtube_dl/extractor/__init__.py
+ $ git add youtube_dl/extractor/yourextractor.py
+ $ git commit -m '[yourextractor] Add new extractor'
+ $ git push origin yourextractor
+
+10. Finally, [create a pull request](https://help.github.com/articles/creating-a-pull-request). We'll then review and merge it.
+
+In any case, thank you very much for your contributions!
# BUGS
For bug reports, this means that your report should contain the *complete* output of youtube-dl when called with the -v flag. The error message you get for (most) bugs even says so, but you would not believe how many of our bug reports do not contain this information.
-Site support requests must contain an example URL. An example URL is a URL you might want to download, like http://www.youtube.com/watch?v=BaW_jenozKc . There should be an obvious video present. Except under very special circumstances, the main page of a video service (e.g. http://www.youtube.com/ ) is *not* an example URL.

### Are you using the latest version?
-Before reporting any issue, type youtube-dl -U. This should report that you're up-to-date. Ábout 20% of the reports we receive are already fixed, but people are using outdated versions. This goes for feature requests as well.
+Before reporting any issue, type youtube-dl -U. This should report that you're up-to-date. About 20% of the reports we receive are already fixed, but people are using outdated versions. This goes for feature requests as well.
### Is the issue already documented?
### Is anyone going to need the feature?
Only post features that you (or an incapicated friend you can personally talk to) require. Do not post features because they seem like a good idea. If they are really useful, they will be requested by someone who requires them.
+
+### Is your question about youtube-dl?
+
+It may sound strange, but some bug reports we receive are completely unrelated to youtube-dl and relate to a different or even the reporter's own application. Please make sure that you are actually using youtube-dl. If you are using a UI for youtube-dl, report the bug to the maintainer of the actual application providing the UI. On the other hand, if your UI for youtube-dl fails in some way you believe is related to youtube-dl, by all means, go ahead and report the bug.
