+On Windows, how should I set up ffmpeg and youtube-dl? Where should I put the exe files?
+
+If you put youtube-dl and ffmpeg in the same directory that you're
+running the command from, it will work, but that's rather cumbersome.
+
+To make a different directory work - either for ffmpeg, or for
+youtube-dl, or for both - simply create the directory (say, C:\bin, or
+C:\Users\<User name>\bin), put all the executables directly in there,
+and then set your PATH environment variable to include that directory.
+
+From then on, after restarting your shell, you will be able to access
+both youtube-dl and ffmpeg (and youtube-dl will be able to find ffmpeg)
+by simply typing youtube-dl or ffmpeg, no matter what directory you're
+in.
+
+How do I put downloads into a specific folder?
+
+Use the -o to specify an output template, for example
+-o "/home/user/videos/%(title)s-%(id)s.%(ext)s". If you want this for
+all of your downloads, put the option into your configuration file.
+
+How do I download a video starting with a -?
+
+Either prepend http://www.youtube.com/watch?v= or separate the ID from
+the options with --:
+
+ youtube-dl -- -wNyEUrxzFU
+ youtube-dl "http://www.youtube.com/watch?v=-wNyEUrxzFU"
+
+How do I pass cookies to youtube-dl?
+
+Use the --cookies option, for example
+--cookies /path/to/cookies/file.txt. Note that the cookies file must be
+in Mozilla/Netscape format and the first line of the cookies file must
+be either # HTTP Cookie File or # Netscape HTTP Cookie File. Make sure
+you have correct newline format in the cookies file and convert newlines
+if necessary to correspond with your OS, namely CRLF (\r\n) for Windows,
+LF (\n) for Linux and CR (\r) for Mac OS. HTTP Error 400: Bad Request
+when using --cookies is a good sign of invalid newline format.
+
+Passing cookies to youtube-dl is a good way to workaround login when a
+particular extractor does not implement it explicitly. Another use case
+is working around CAPTCHA some websites require you to solve in
+particular cases in order to get access (e.g. YouTube, CloudFlare).
+
+Can you add support for this anime video site, or site which shows current movies for free?
+
+As a matter of policy (as well as legality), youtube-dl does not include
+support for services that specialize in infringing copyright. As a rule
+of thumb, if you cannot easily find a video that the service is quite
+obviously allowed to distribute (i.e. that has been uploaded by the
+creator, the creator's distributor, or is published under a free
+license), the service is probably unfit for inclusion to youtube-dl.
+
+A note on the service that they don't host the infringing content, but
+just link to those who do, is evidence that the service should NOT be
+included into youtube-dl. The same goes for any DMCA note when the whole
+front page of the service is filled with videos they are not allowed to
+distribute. A "fair use" note is equally unconvincing if the service
+shows copyright-protected videos in full without authorization.
+
+Support requests for services that DO purchase the rights to distribute
+their content are perfectly fine though. If in doubt, you can simply
+include a source that mentions the legitimate purchase of content.
+
+How can I speed up work on my issue?
+
+(Also known as: Help, my important issue not being solved!) The
+youtube-dl core developer team is quite small. While we do our best to
+solve as many issues as possible, sometimes that can take quite a while.
+To speed up your issue, here's what you can do:
+
+First of all, please do report the issue at our issue tracker. That
+allows us to coordinate all efforts by users and developers, and serves
+as a unified point. Unfortunately, the youtube-dl project has grown too
+large to use personal email as an effective communication channel.
+
+Please read the bug reporting instructions below. A lot of bugs lack all
+the necessary information. If you can, offer proxy, VPN, or shell access
+to the youtube-dl developers. If you are able to, test the issue from
+multiple computers in multiple countries to exclude local censorship or
+misconfiguration issues.
+
+If nobody is interested in solving your issue, you are welcome to take
+matters into your own hands and submit a pull request (or coerce/pay
+somebody else to do so).
+
+Feel free to bump the issue from time to time by writing a small comment
+("Issue is still present in youtube-dl version ...from France, but fixed
+from Belgium"), but please not more than once a month. Please do not
+declare your issue as important or urgent.
+
+How can I detect whether a given URL is supported by youtube-dl?
+
+For one, have a look at the list of supported sites. Note that it can
+sometimes happen that the site changes its URL scheme (say, from
+http://example.com/video/1234567 to http://example.com/v/1234567 ) and
+youtube-dl reports an URL of a service in that list as unsupported. In
+that case, simply report a bug.
+
+It is _not_ possible to detect whether a URL is supported or not. That's
+because youtube-dl contains a generic extractor which matches ALL URLs.
+You may be tempted to disable, exclude, or remove the generic extractor,
+but the generic extractor not only allows users to extract videos from
+lots of websites that embed a video from another service, but may also
+be used to extract video from a service that it's hosting itself.
+Therefore, we neither recommend nor support disabling, excluding, or
+removing the generic extractor.
+
+If you want to find out whether a given URL is supported, simply call
+youtube-dl with it. If you get no videos back, chances are the URL is
+either not referring to a video or unsupported. You can find out which
+by examining the output (if you run youtube-dl on the console) or
+catching an UnsupportedError exception if you run it from a Python
+program.
+
+
+
+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:
+
+ # 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)
+ webpage = self._download_webpage(url, video_id)
+
+ # TODO more code goes here, for example ...
+ title = self._html_search_regex(r'<h1>(.+?)</h1>', webpage, 'title')
+
+ return {
+ 'id': video_id,
+ 'title': title,
+ 'description': self._og_search_description(webpage),
+ 'uploader': self._search_regex(r'<div[^>]+id="uploader"[^>]*>([^<]+)<', webpage, 'uploader', fatal=False),
+ # 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 then be named TestDownload.test_YourExtractor,
+ TestDownload.test_YourExtractor_1,
+ TestDownload.test_YourExtractor_2, etc.
+7. Have a look at youtube_dl/extractor/common.py for possible helper
+ methods and a detailed description of what your extractor should and
+ may return. Add tests and code for as many as you want.
+8. If you can, check the code with flake8.
+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'
+ $ git push origin yourextractor
+
+10. Finally, create a pull request. We'll then review and merge it.
+
+In any case, thank you very much for your contributions!

+
+
+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:
+
+ from __future__ import unicode_literals
+ 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.
+
+Here's a more complete example of a program that outputs only errors
+(and a short message after the download is finished), and
+downloads/converts the video to an mp3 file:
+
+ from __future__ import unicode_literals
+ import youtube_dl
+
+
+ class MyLogger(object):
+ def debug(self, msg):
+ pass
+
+ def warning(self, msg):
+ pass
+
+ def error(self, msg):
+ print(msg)
+
+
+ def my_hook(d):
+ if d['status'] == 'finished':
+ print('Done downloading, now converting ...')
+
+
+ ydl_opts = {
+ 'format': 'bestaudio/best',
+ 'postprocessors': [{
+ 'key': 'FFmpegExtractAudio',
+ 'preferredcodec': 'mp3',
+ 'preferredquality': '192',
+ }],
+ 'logger': MyLogger(),
+ 'progress_hooks': [my_hook],
+ }
+ with youtube_dl.YoutubeDL(ydl_opts) as ydl:
+ ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])
