Video Format Options:
---------------------

- preference using slashes: "-f 22/17/18".
- "-f mp4" and "-f flv" are also supported.
- You can also use the special names "best",
- "bestvideo", "bestaudio", "worst",
- "worstvideo" and "worstaudio". By default,
- youtube-dl will pick the best quality.
+ preference using slashes, as in -f 22/17/18
+ . Instead of format codes, you can select
+ by extension for the extensions aac, m4a,
+ mp3, mp4, ogg, wav, webm. You can also use
+ the special names "best", "bestvideo",
+ "bestaudio", "worst". You can filter the
+ video results by putting a condition in
+ brackets, as in -f "best[height=720]" (or
+ -f "[filesize>10M]"). This works for
+ filesize, height, width, tbr, abr, vbr,
+ asr, and fps and the comparisons <, <=, >,
+ >=, =, != and for ext, acodec, vcodec,
+ container, and protocol and the comparisons
+ =, != . Formats for which the value is not
+ known are excluded unless you put a
+ question mark (?) after the operator. You
+ can combine format filters, so -f "[height
+ <=? 720][tbr>500]" selects up to 720p
+ videos (or videos where the height is not
+ known) with a bitrate of at least 500
+ KBit/s. By default, youtube-dl will pick
+ the best quality. Use commas to download
+ multiple audio formats, such as -f
+ 136/137/mp4/bestvideo,140/m4a/bestaudio.
+ You can merge the video and audio of two
+ formats into a single file using -f <video-
+ format>+<audio-format> (requires ffmpeg or
+ avconv), for example -f
+ bestvideo+bestaudio.
--all-formats download all available video formats
--prefer-free-formats prefer free video formats unless a specific
one is requested
--max-quality FORMAT highest quality format to download
-F, --list-formats list all available formats
+ --youtube-skip-dash-manifest Do not download the DASH manifest on
+ YouTube videos
+ --merge-output-format FORMAT If a merge is required (e.g.
+ bestvideo+bestaudio), output to given
+ container format. One of mkv, mp4, ogg,
+ webm, flv.Ignored if no merge is required

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+distribution packages are often outdated.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
Once the video is fully downloaded, use any video player, such as vlc or
mplayer.
-The links provided by youtube-dl -g are not working anymore
+I extracted a video URL with -g, but it does not play on another machine / in my webbrowser.
+
+It depends a lot on the service. In many cases, requests for the video
+(to download/play it) must come from the same IP address and with the
+same 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.
+
+It may be beneficial to use IPv6; in some cases, the restrictions are
+only applied to IPv4. Some services (sometimes only for a subset of
+videos) do not restrict the video URL by IP address, cookie, or
+user-agent, but these are the exception rather than the rule.
-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.
+Please bear in mind that some URL protocols are not supported by
+browsers out of the box, including RTMP. If you are using -g, your own
+downloader must support these as well.
+
+If you want to play the video on a machine that is not running
+youtube-dl, you can relay the video content from the machine that runs
+youtube-dl. You can use -o - to let youtube-dl stream a video to stdout,
+or simply allow the player to download the files written by youtube-dl
+in turn.

SyntaxError: Non-ASCII character
To run the exe you need to install first the Microsoft Visual C++ 2008
Redistributable Package.
+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"
+
+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 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
======================
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)
- }
+ ``` {.python}

+ _TEST = {
+ 'url': 'http://yourextractor.com/watch/42',
+ 'md5': 'TODO: md5 sum of the first 10241 bytes of the video file (use --test)',

+ }
- def _real_extract(self, url):
- mobj = re.match(self._VALID_URL, url)

+ ```
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.

+ _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.

- (optional, ignore E501).

+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:
+
+``` {.python}
+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:
+
+``` {.python}
+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'])
+```
