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.x (x being at least 6), and it is not platform specific. It
-should work in your Unix box, in Windows or in Mac OS X. It is released
-to the public domain, which means you can modify it, redistribute it or
-use it however you like.
+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.
OPTIONS
=======
- -h, --help print this help text and exit
- --version print program version and exit
- -U, --update update this program to latest version
- -i, --ignore-errors continue on download errors
- -r, --rate-limit LIMIT download rate limit (e.g. 50k or 44.6m)
- -R, --retries RETRIES number of retries (default is 10)
- --buffer-size SIZE size of download buffer (e.g. 1024 or 16k) (default
- is 1024)
- --no-resize-buffer do not automatically adjust the buffer size. By
- default, the buffer size is automatically resized
- from an initial value of SIZE.
- --dump-user-agent display the current browser identification
- --user-agent UA specify a custom user agent
- --list-extractors List all supported extractors and the URLs they
- would handle
+ -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
+ 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
+ --list-extractors List all supported extractors and the URLs

+ from google videos for youtube-dl "large
+ apple". Use the value "auto" to let
+ youtube-dl guess ("auto_warning" to emit a
+ warning when guessing). "error" just throws
+ an error. The default value "fixup_error"
+ repairs broken URLs, but emits an error if
+ this is not possible instead of searching.

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 ~/.local/config/youtube-dl.conf.
+mtime) into /etc/youtube-dl.conf and/or ~/.config/youtube-dl/config. On
+Windows, the configuration file locations are
+%APPDATA%\youtube-dl\config.txt and C:\Users\<Yourname>\youtube-dl.conf.
OUTPUT TEMPLATE
===============
the file.
- autonumber: The sequence will be replaced by a five-digit number
that will be increased with each download, starting at zero.
+- playlist: The name or the id of the playlist that contains the
+ video.
+- playlist_index: The index of the video in the playlist, a five-digit
+ number.
-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).
+The current default template is %(title)s-%(id)s.%(ext)s.
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
+``` {.bash}
+$ 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
+```
+
+VIDEO SELECTION
+===============
+
+Videos can be filtered by their upload date using the options --date,
+--datebefore or --dateafter, they accept dates in two formats:
+
+- Absolute dates: Dates in the format YYYYMMDD.
+- Relative dates: Dates in the format
+ (now|today)[+-][0-9](day|week|month|year)(s)?
+
+Examples:
+
+``` {.bash}
+# Download only the videos uploaded in the last 6 months
+$ youtube-dl --dateafter now-6months
+
+# Download only the videos uploaded on January 1, 1970
+$ youtube-dl --date 19700101
+
+$ # will only download the videos uploaded in the 200x decade
+$ youtube-dl --dateafter 20000101 --datebefore 20091231
+```
FAQ
===
+How do I update youtube-dl?
+
+If you've followed our manual installation instructions, you can simply
+run youtube-dl -U (or, on Linux, sudo youtube-dl -U).
+
+If you have used pip, a simple sudo pip install -U youtube-dl is
+sufficient to update.
+
+If you have installed youtube-dl using a package manager like apt-get or
+yum, use the standard system update mechanism to update. Note that
+distribution packages are often outdated. As a rule of thumb, youtube-dl
+releases at least once a month, and often weekly or even daily. Simply
+go to http://yt-dl.org/ to find out the current version. Unfortunately,
+there is nothing we youtube-dl developers can do if your distributions
+serves a really outdated version. You can (and should) complain to your
+distribution in their bugtracker or support forum.
+
+As a last resort, you can also uninstall the version installed by your
+package manager and follow our manual installation instructions. For
+that, remove the distribution's package, with a line like
+
+ sudo apt-get remove -y youtube-dl
+
+Afterwards, simply follow our manual installation instructions:
+
+ sudo wget https://yt-dl.org/latest/youtube-dl -O /usr/local/bin/youtube-dl
+ sudo chmod a+x /usr/local/bin/youtube-dl
+ hash -r
+
+Again, from then on you'll be able to update with sudo youtube-dl -U.
+
+I'm getting an error Unable to extract OpenGraph title on YouTube playlists
+
+YouTube changed their playlist format in March 2014 and later on, so
+you'll need at least youtube-dl 2014.07.25 to download all YouTube
+videos.
+
+If you have installed youtube-dl with a package manager, pip, setup.py
+or a tarball, please use that to update. Note that Ubuntu packages do
+not seem to get updated anymore. Since we are not affiliated with
+Ubuntu, there is little we can do. Feel free to report bugs to the
+Ubuntu packaging guys - all they have to do is update the package to a
+somewhat recent version. See above for a way to update.
+
+Do I always have to pass in --max-quality FORMAT, or -citw?
+
+By default, youtube-dl intends to have the best options (incidentally,
+if you have a convincing case that these should be different, please
+file an issue where you explain that). Therefore, it is unnecessary and
+sometimes harmful to copy long option strings from webpages. In
+particular, --max-quality limits the video quality (so if you want the
+best quality, do NOT pass it in), and the only option out of -citw that
+is regularly useful is -i.
+
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
+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
+too much. We're considering to provide a way to let you solve the
CAPTCHA, but at the moment, your best course of action is pointing a
webbrowser to the youtube URL, solving the CAPTCHA, and restart
youtube-dl.
To run the exe you need to install first the Microsoft Visual C++ 2008
Redistributable Package.
+DEVELOPER INSTRUCTIONS
+======================
+
+Most users do not need to build youtube-dl and can download the builds
+or get them from their distribution.
+
+To run youtube-dl as a developer, you don't need to build anything
+either. Simply execute
+
+ python -m youtube_dl
+
+To run the test, simply invoke your favorite test runner, or execute a
+test file directly; any of the following work:
+
+ python -m unittest discover
+ python test/test_download.py
+ nosetests
+
+If you want to create a build of youtube-dl yourself, you'll need
+
+- python
+- make
+- pandoc
+- zip
+- nosetests
+
+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
+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:
+
+ ``` {.python}
+ # coding: utf-8
+ from __future__ import unicode_literals
+
+ 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 10241 bytes of the video file (use --test)',
+ 'info_dict': {
+ 'id': '42',
+ 'ext': 'mp4',
+ 'title': 'Video title goes here',
+ 'thumbnail': 're:^https?://.*\.jpg$',
+ # 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):
+ video_id = self._match_id(url)
+
+ # 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.
+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. If you decide to add more than one test, then rename
+ _TEST to _TESTS and make it into a list of dictionaries. The tests
+ will be then be named TestDownload.test_YourExtractor,
+ TestDownload.test_YourExtractor_1,
+ TestDownload.test_YourExtractor_2, etc.
+7. Have a look at youtube_dl/common/extractor/common.py for possible
+ helper methods and a detailed description of what your extractor
+ should return. Add tests and code for as many as you want.
+8. If you can, check the code with pyflakes (a good idea) and pep8
+ (optional, ignore E501).
+9. When the tests pass, add the new files and commit them and push 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'

+EMBEDDING YOUTUBE-DL
+====================
+
+youtube-dl makes the best effort to be a good command-line program, and
+thus should be callable from any programming language. If you encounter
+any problems parsing its output, feel free to create a report.
+
+From a Python program, you can embed youtube-dl in a more powerful
+fashion, like this:
+
+ import youtube_dl
+
+ ydl_opts = {}
+ with youtube_dl.YoutubeDL(ydl_opts) as ydl:
+ ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])
+
+Most likely, you'll want to use various options. For a list of what can
+be done, have a look at youtube_dl/YoutubeDL.py. For a start, if you
+want to intercept youtube-dl's output, set a logger object.
+
+BUGS
+====
+
+Bugs and suggestions should be reported at:
+https://github.com/rg3/youtube-dl/issues . Unless you were prompted so
+or there is another pertinent reason (e.g. GitHub fails to accept the
+bug report), please do not send bug reports via personal email.
+
+Please include the full output of the command when run with --verbose.
+The output (including the first lines) contain important debugging
+information. Issues without the full output are often not reproducible
+and therefore do not get solved in short order, if ever.
+
+For discussions, join us in the irc channel #youtube-dl on freenode.
+
+When you submit a request, please re-read it once to avoid a couple of
+mistakes (you can and should use this as a checklist):
+
+Is the description of the issue itself sufficient?
+
+We often get issue reports that we cannot really decipher. While in most
+cases we eventually get the required information after asking back
+multiple times, this poses an unnecessary drain on our resources. Many
+contributors, including myself, are also not native speakers, so we may
+misread some parts.
+
+So please elaborate on what feature you are requesting, or what bug you
+want to be fixed. Make sure that it's obvious
+
+- What the problem is
+- How it could be fixed
+- How your proposed solution would look like
+
+If your report is shorter than two lines, it is almost certainly missing
+some of these, which makes it hard for us to respond to it. We're often
+too polite to close the issue outright, but the missing info makes
+misinterpretation likely. As a commiter myself, I often get frustrated
+by these issues, since the only possible way for me to move forward on
+them is to ask for clarification over and over.
+
+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. 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?
+
+Make sure that someone has not already opened the issue you're trying to
+open. Search at the top of the window or at
+https://github.com/rg3/youtube-dl/search?type=Issues . If there is an
+issue, feel free to write something along the lines of "This affects me
+as well, with version 2015.01.01. Here is some more information on the
+issue: ...". While some issues may be old, a new post into them often
+spurs rapid activity.
+
+Why are existing options not enough?
+
+Before requesting a new feature, please have a quick peek at the list of
+supported options. Many feature requests are for features that actually
+exist already! Please, absolutely do show off your work in the issue
+report and detail how the existing similar options do not solve your
+problem.
+
+Is there enough context in your bug report?
+
+People want to solve problems, and often think they do us a favor by
+breaking down their larger problems (e.g. wanting to skip already
+downloaded files) to a specific request (e.g. requesting us to look
+whether the file exists before downloading the info page). However, what
+often happens is that they break down the problem into two steps: One
+simple, and one impossible (or extremely complicated one).
+
+We are then presented with a very complicated request when the original
+problem could be solved far easier, e.g. by recording the downloaded
+video IDs in a separate file. To avoid this, you must include the
+greater context where it is non-obvious. In particular, every feature
+request that does not consist of adding support for a new site should
+contain a use case scenario that explains in what situation the missing
+feature would be useful.
+
+Does the issue involve one problem, and one problem only?
+
+Some of our users seem to think there is a limit of issues they can or
+should open. There is no limit of issues they can or should open. While
+it may seem appealing to be able to dump all your issues into one
+ticket, that means that someone who solves one of your issues cannot
+mark the issue as closed. Typically, reporting a bunch of issues leads
+to the ticket lingering since nobody wants to attack that behemoth,
+until someone mercifully splits the issue into multiple ones.
+
+In particular, every site support request issue should only pertain to
+services at one site (generally under a common domain, but always using
+the same backend technology). Do not request support for vimeo user
+videos, Whitehouse podcasts, and Google Plus pages in the same issue.
+Also, make sure that you don't post bug reports alongside feature
+requests. As a rule of thumb, a feature request does not include outputs
+of youtube-dl that are not immediately related to the feature at hand.
+Do not post reports of a network error alongside the request for a new
+video service.
+
+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.
