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 3.2+, 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.

youtube-dl [OPTIONS] URL [URL...]

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 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
--extractor-descriptions         Output descriptions of all supported extractors
--force-generic-extractor        Force extraction to use the generic extractor
--default-search PREFIX          Use this prefix for unqualified URLs. For example "gvsearch2:" downloads two videos 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 any supported command line option to a configuration file. On Linux, system wide configuration file is located at /etc/youtube-dl.conf and user wide configuration file at ~/.config/youtube-dl/config. On Windows, the user wide configuration file locations are %APPDATA%\youtube-dl\config.txt or C:\Users\<user name>\youtube-dl.conf. For example, with the following configration file youtube-dl will always extract the audio, not copy the mtime and use proxy:

--extract-audio
--no-mtime
--proxy 127.0.0.1:3128

You can use --ignore-config if you want to disable configuration file for a particular youtube-dl run.

Authentication with `.netrc` file

You may also want to configure automatic credentials storage for extractors that support authentication (by providing login and password with --username and --password) in order not to pass credentials as command line arguments on every youtube-dl execution and prevent tracking plain text passwords in shell command history. You can achieve this using .netrc file on per extractor basis. For that you will need to create .netrc file in your $HOME and restrict permissions to read/write by you only:

touch $HOME/.netrc
chmod a-rwx,u+rw $HOME/.netrc

After that you can add credentials for extractor in the following format, where extractor is the name of extractor in lowercase:

machine <extractor> login <login> password <password>

For example:

machine youtube login myaccount@gmail.com password my_youtube_password
machine twitch login my_twitch_account_name password my_twitch_password

To activate authentication with .netrc file you should pass --netrc to youtube-dl or to place it in configuration file.

On Windows you may also need to setup %HOME% environment variable manually.

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.
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.
format_id: The sequence will be replaced by the format code specified by --format.

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

FORMAT SELECTION

By default youtube-dl tries to download the best quality, but sometimes you may want to download other format. The simplest case is requesting a specific format, for example -f 22. You can get the list of available formats using --list-formats, you can also use a file extension (currently it supports aac, m4a, mp3, mp4, ogg, wav, webm) or the special names best, bestvideo, bestaudio and worst.

If you want to download multiple videos and they don't have the same formats available, you can specify the order of preference using slashes, as in -f 22/17/18. You can also 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. Use commas to download multiple 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. Format selectors can also be grouped using parentheses, for example if you want to download the best mp4 and webm formats with a height lower than 480 you can use -f '(mp4,webm)[height<480]'.

Since the end of April 2015 and version 2015.04.26 youtube-dl uses -f bestvideo+bestaudio/best as default format selection (see #5447, #5456). If ffmpeg or avconv are installed this results in downloading bestvideo and bestaudio separately and muxing them together into a single file giving the best overall quality available. Otherwise it falls back to best and results in downloading best available quality served as a single file. best is also needed for videos that don't come from YouTube because they don't provide the audio and video in two different files. If you want to only download some dash formats (for example if you are not interested in getting videos with a resolution higher than 1080p), you can add -f bestvideo[height<=?1080]+bestaudio/bestto your configuration file. Note that if you use youtube-dl to stream to stdout (and most likely to pipe it to your media player then), i.e. you explicitly specify output template as -o -, youtube-dl still uses -f best format selection in order to start content delivery immediately to your player and not to wait until bestvideo and bestaudio are downloaded and muxed.

If you want to preserve the old format selection behavior (prior to youtube-dl 2015.04.26), i.e. you want to download best available quality media served as a single file, you should explicitly specify your choice with -f best. You may want to add it to the configuration file in order not to type it every time you run youtube-dl.

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:

# 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 `-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, 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 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, 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 or mplayer.

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.

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.

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. See above for how to update youtube-dl.

ERROR: unable to download video

YouTube requires an additional signature since September 2012 which is not supported by old versions of youtube-dl. See above for how to update youtube-dl.

Video URL contains an ampersand and I'm getting some strange output `[1] 2839` or `'v' is not recognized as an internal or external command`

That's actually the output from your shell. Since ampersand is one of the special shell characters it's interpreted by shell preventing you from passing the whole URL to youtube-dl. To disable your shell from interpreting the ampersands (or any other special characters) you have to either put the whole URL in quotes or escape them with a backslash (which approach will work depends on your shell).

For example if your URL is https://www.youtube.com/watch?t=4&v=BaW_jenozKc you should end up with following command:

youtube-dl 'https://www.youtube.com/watch?t=4&v=BaW_jenozKc'

youtube-dl https://www.youtube.com/watch?t=4\&v=BaW_jenozKc

For Windows you have to use the double quotes:

youtube-dl "https://www.youtube.com/watch?t=4&v=BaW_jenozKc"

ExtractorError: Could not find JS function u'OF'

In February 2015, the new YouTube player contained a character sequence in a string that was misinterpreted by old versions of youtube-dl. See above for how to update youtube-dl.

HTTP Error 429: Too Many Requests or 402: Payment Required

These two error codes indicate that the service is blocking your IP address because of overuse. Contact the service and ask them to unblock your IP address, or - if you have acquired a whitelisted IP address already - use the --proxy or --source-address options to select another IP address.

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.

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 cookies file must be in Mozilla/Netscape format and the first line of cookies file must be either # HTTP Cookie File or # Netscape HTTP Cookie File. Make sure you have correct newline formatin cookies file and convert newlines if necessary to correspond 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 particular extractor does not implement it explicitly.

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):

Fork this repository
Check out the source code with git clone git@github.com:YOUR_GITHUB_USERNAME/youtube-dl.git
Start a new git branch with cd youtube-dl; git checkout -b yourextractor

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),
            # TODO more properties (see youtube_dl/extractor/common.py)
        }

Add an import in youtube_dl/extractor/__init__.py.
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.
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.
If you can, check the code with flake8.

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

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 loggerobject.

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'])

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. For discussions, join us in the irc channel #youtube-dl on freenode.

Please include the full output of youtube-dl when run with -v.

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.

Please re-read your issue once again to avoid a couple of common 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.

If your server has multiple IPs or you suspect censorship, adding --call-home may be a good idea to get more diagnostics. If the error is ERROR: Unable to extract ... and you cannot reproduce it from multiple countries, add --dump-pages (warning: this will yield a rather large output, redirect it to the file log.txt by adding >log.txt 2>&1 to your command-line) or upload the .dump files you get when you add --write-pages somewhere.

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 incapacitated 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.

我的补充说明：

chmod 755 youtube-dl

./youtube-dl --proxy socks5://127.0.0.1:10086 -f mp4 https://youtu.be/jegxKxpJ060

即可成功下载youtube video.

在windows 桌面系统上，

下载https://github.com/ytdl-org/youtube-dl/releases/download/2021.12.17/youtube-dl.exe 运行cmd.exe, 在cmd.exe里面，cd到youtube-dl.exe所在的目录，

youtube-dl.exe --proxy socks5://127.0.0.1:10086 --format mp4 https://youtu.be/jegxKxpJ060

不知为什么，我运行此命令遇到错误。

或者：先挂一个vpn(比如openvpn), 然后运行：

youtube-dl.exe https://youtu.be/jegxKxpJ060

这样就ok了。看样子此处使用socks proxy或http proxy是不合适的，最好改用vpn.

youtube-dl.exe 下载视频没有yt-dlp.exe(https://github.com/yt-dlp/yt-dlp/releases/download/2022.09.01/yt-dlp.exe)快，所以推荐使用yt-dlp.exe

sudo chmod a+rx /usr/local/bin/youtube-dl

如果你的vps没有安装 curl ，可以使用 wget 来下载。


sudo wget https://yt-dl.org/downloads/2016.07.13/youtube-dl -O /usr/local/bin/youtube-dl
sudo chmod a+rx /usr/local/bin/youtube-dl

当然你也可以用pip来安装，如果你没有pip就先安装pip， apt-get install python-pip -y


sudo pip install --upgrade youtube_dl

OS X系统安装：


sudo wget https://yt-dl.org/downloads/2016.07.13/youtube-dl.sig -O youtube-dl.sig
gpg --verify youtube-dl.sig /usr/local/bin/youtube-dl
rm youtube-dl.sig

Windows系统安装：

直接官方下载一个exe文件就行了。

Windows exe

但是，要运行这个程序还需要安装微软的运行库。

Microsoft Visual C++ 2010 Redistributable Package (x86)

基础功能介绍

Youtube-dl的官网是：http://rg3.github.io/youtube-dl/

Github项目地址是：https://github.com/rg3/youtube-dl

在这里都能看到最新最全的youtube-dl信息。

Youtube-dl支持八百多家视频网站，具体列表可以看这里：http://rg3.github.io/youtube-dl/supportedsites.html ，优酷、爱奇艺等国内视频网站也是支持的。

下载视频

以下教程均以 这个youtube视频链接为例 https://www.youtube.com/watch?v=jK5coaM2X9g

最基础的下载视频的方法很简单，直接 youtube-dl URL


youtube-dl https://www.youtube.com/watch?v=jK5coaM2X9g

这样就会自动选择一个最好的视频格式和清晰度下载到 当前的文件夹 了。

如果想把这个视频的所有格式都下载下来怎么办？

下载全部格式


youtube-dl  --all-formats https://www.youtube.com/watch?v=jK5coaM2X9g

–all-formats ：添加这个参数之后，所有存在的格式全部下载；

但是你又不想全部下载，想挑选指定视频的格式和清晰度怎么办？

列出视频的所有格式/清晰度

–list-formats/-F：这是一个列清单参数，执行后并不会下载视频，但能知道这个目标视频都有哪些格式存在，这样就可以有选择的下载啦！


youtube-dl --list-formats https://www.youtube.com/watch?v=jK5coaM2X9g

然后就会看到一大片的视频格式，如果你要下载其中一个，请看前面第一列的编号ID。

下载指定格式视频

-f + 编号：通过上一步获取到了所有视频格式的列表，第一列就是编号对应着不同的格式，例如我想下载22号那个mp4格式分辨率为1280*720的视频，则按下面的命令就可以轻松指定下载视频哦；


youtube-dl -f 22 https://www.youtube.com/watch?v=jK5coaM2X9g

离线下载/后台下载

我发现Toutube-dl不带有后台下载的功能，或者说我没找到命令，不过没事，可以试用 screen 来实现。

首先如果你没有安装 screen 的话请先安装。

Debian/Ubuntu系统安装：


apt-get update
apt-get install screen

Centos系统安装：


yum update
yum  install screen

然后用 -S 创建一个活动，这时候你就进入了这个活动中，你就可以去下载视频了，这时候即使关闭ssh也不会断开下载。


screen -S video

如果你不小心关闭ssh或者想要重新查看 video活动，可以用 -r 来重新进入这个活动


screen -r video

VPS中在线播放

这个其实很简单，HTML5本身就可以去播放指定格式的视频，所以我们只需要搭建一个nginx或者apache，把视频下载到默认虚拟主机的文件夹里，就可以在线观看了.

需要注意的是，HTML5支持在线播放的格式有限，建议下载 mp4 和 Webm 格式的，免得HTML5无法在线播放。

我们这里以apache为例，先安装apache。

Debian/Ubuntu系统安装：


apt-get install apache2 -y

Centos系统安装：


yum install httpd -y

然后去 /var/www 目录下载视频。


cd /var/www

下载好了之后用 ls -a 查看当前目录下的文件，找到你的视频文件名称，比如：233.mp4

然后打开网页： http://你的VPS_IP/233.mp4

就可以在线观看了。

当然这样看视频也会有一些不方便，不能方便的选视频.

当然你也可以直接使用 apache/nginx 自带的列表功能，开启方法很简单，只要删掉/var/www目录下的index.html文件，这时候访问你的 http://vps_IP/ 就可以看到一个简陋的列表了。


rm -rf /var/www/index.html

如果你安装的是nginx （通过apt-get install -y 、 yum install nginx -y 安装的才是），那默认的虚拟主机文件夹是 /usr/share/nginx/www


rm -rf /usr/share/nginx/www/index.html

如果你安装的是上面我说的 lnmp.rog 中的lnmp一键包，那默认虚拟主机文件夹就是 /home/wwwroot/default


rm -rf /home/wwwroot/default/index.html

youtube-dl

youtube-dl是一个使用python编写的脚本，可以下载热门视频网站的视频。在Linux系统下可以一健下载Youtube、Youku、Tudou等热门网站的视频等。

介绍安装及使用方法，以使用debian系统下为例

1、在SSH命令行下

curl -L https://yt-dl.org/downloads/latest/youtube-dl -o /usr/local/bin/youtube-dl
chmod a+rx /usr/local/bin/youtube-dl

如何提示错误，请安装curl

apt-get install curl

2、运行youtube-dl,如果提示错误，请安装Python

apt-get install python

youtube-dl 升级最新版本

youtube-dl -U

3、用法

youtube-dl URL

URL换成具体某个视频的URL就可以直接下载了。注意，youtube-dl会默认下载视频到当前执行命令的目录下。

4、youtube-dl的一个激动人心的功能：支持读取下载链接列表文件。

这意味着我可以先把所有下载链接整理好后放进一个txt文件，然后让youtube-dl去读取这个txt文件就行了，接下来它就会自动下载全部的视频

5、在Putty命令行界面中创建一个专门的目录用于存放下载的视频文件，然后CD至此目录下，创建一个包含所有下载链接的txt文件（使用vi命令即可）。

在此目录下，执行下列命令，下载多个文件：

youtube-dl -c -i -a video_url.txt

youtube-dl提供了很多有用的附加参数，这里用到的是：

-a 参数表示读取外部链接文件。
-c 断点续传（如果由于意外原因下载中断了，再次启动下载命令时，可以实现断点续传）
-i 忽略报错（如果出现某些链接无法打开或者下载的问题，会自动绕过，继续下载其他视频）

编译自　|　https://www.howtoforge.com/tutorial/install-and-use-youtube-dl-on-ubuntu-1604/
　作者　|　Hitesh Jethva
　译者　|　lujun9972

Youtube-dl 是一个自由开源的命令行视频下载工具，可以用来从 Youtube 等类似的网站上下载视频，目前它支持的网站除了 Youtube 还有 Facebook、Dailymotion、Google Video、Yahoo 等等。它构架于 pygtk 之上，需要 Python 的支持来运行。它支持很多操作系统，包括 Windows、Mac 以及 Unix。Youtube-dl 还有断点续传、下载整个频道或者整个播放清单中的视频、添加自定义的标题、代理等等其他功能。

本文中，我们将来学习如何在 Ubuntu 16.04 上安装并使用 Youtube-dl 和 Youtube-dlg。我们还会学习如何以不同质量，不同格式来下载 Youtube 中的视频。

前置需求

◈ 一台运行 Ubuntu 16.04 的服务器。

◈ 非 root 用户但拥有 sudo 特权。

让我们首先用下面命令升级系统到最新版：


sudo apt-get update -y
sudo apt-get upgrade -y

然后重启系统应用这些变更。

安装 Youtube-dl

默认情况下，Youtube-dl 并不在 Ubuntu-16.04 仓库中。你需要从官网上来下载它。使用 curl 命令可以进行下载：

首先，使用下面命令安装 curl：


sudo apt-get install curl -y

然后，下载 youtube-dl 的二进制包：


curl -L https://yt-dl.org/latest/youtube-dl -o /usr/bin/youtube-dl

接着，用下面命令更改 youtube-dl 二进制包的权限：


sudo chmod 755 /usr/bin/youtube-dl

youtube-dl 算是安装好了，现在可以进行下一步了。

使用 Youtube-dl

运行下面命令会列出 youtube-dl 的所有可选项：


youtube-dl --h

youtube-dl 支持多种视频格式，像 Mp4，WebM，3gp，以及 FLV 都支持。你可以使用下面命令列出指定视频所支持的所有格式：


youtube-dl -F https://www.youtube.com/watch?v=j_JgXJ-apXs

如下所示，你会看到该视频所有可能的格式：

137          mp4        1920x1080  DASH video 2217k , avc1.640028, 24fps, video only, 15.28MiB
17           3gp        176x144    small , mp4v.20.3, mp4a.40.2@ 24k
36           3gp        320x180    small , mp4v.20.3, mp4a.40.2
43           webm       640x360    medium , vp8.0, vorbis@128k
18           mp4        640x360    medium , avc1.42001E, mp4a.40.2@ 96k
22           mp4        1280x720   hd720 , avc1.64001F, mp4a.40.2@192k (best)

然后使用 -f 指定你想要下载的格式，如下所示：


youtube-dl -f 18 https://www.youtube.com/watch?v=j_JgXJ-apXs

该命令会下载 640x360 分辨率的 mp4 格式的视频：


[youtube] j_JgXJ-apXs: Downloading webpage
[youtube] j_JgXJ-apXs: Downloading video info webpage
[youtube] j_JgXJ-apXs: Extracting video information
[youtube] j_JgXJ-apXs: Downloading MPD manifest
[download] Destination: B.A. PASS 2 Trailer no 2 _ Filmybox-j_JgXJ-apXs.mp4
[download] 100% of 6.90MiB in 00:47

如果你想以 mp3 音频的格式下载 Youtube 视频，也可以做到：


youtube-dl https://www.youtube.com/watch?v=j_JgXJ-apXs -x --audio-format mp3

你也可以下载指定频道中的所有视频，只需要把频道的 URL 放到后面就行，如下所示：


youtube-dl -citw https://www.youtube.com/channel/UCatfiM69M9ZnNhOzy0jZ41A

若你的网络需要通过代理，那么可以使用 --proxy 来下载视频：


youtube-dl --proxy http://proxy-ip:port https://www.youtube.com/watch?v=j_JgXJ-apXs

若想一条命令下载多个 Youtube 视频，那么首先把所有要下载的 Youtube 视频 URL 存在一个文件中（假设这个文件叫 youtube-list.txt），然后运行下面命令：


youtube-dl -a youtube-list.txt

安装 Youtube-dl GUI

若你想要图形化的界面，那么 youtube-dlg 是你最好的选择。youtube-dlg 是一款由 wxPython 所写的免费而开源的 youtube-dl 界面。

该工具默认也不在 Ubuntu 16.04 仓库中。因此你需要为它添加 PPA。


sudo add-apt-repository ppa:nilarimogard/webupd8

下一步，更新软件包仓库并安装 youtube-dlg：


sudo apt-get update -y
sudo apt-get install youtube-dlg -y

安装好 Youtube-dl 后，就能在 Unity Dash 中启动它了：

现在你只需要将 URL 粘贴到上图中的 URL 域就能下载视频了。Youtube-dlg 对于那些不太懂命令行的人来说很有用。

结语

恭喜你！你已经成功地在 Ubuntu 16.04 服务器上安装好了 youtube-dl 和 youtube-dlg。你可以很方便地从 Youtube 及任何 youtube-dl 支持的网站上以任何格式和任何大小下载视频了。

youtube-dl 的作用在于，可以将 YouTube 等视频网站的各种视频全部下载下来，虽然它的名字只写了 YouTube，但其实支持现在大多数的视频网站。

那么该如何使用呢？
使用方法
以Windows系统为例，需要安装python，所以我们前往python官网，下载python的安装包来安装，python官网：
https://www.python.org/

安装好后，在键盘按下“win”+r输入cmd，调出命令窗口，输入python，如果出现版本信息，说明python安装成功了，咱们就可以进行下一步.
然后前往youtube-dl官网，将youtube-dl的安装包下载下来.
下载 “youtube-dl.exe”，将它放在一个文件夹当中。接着，开启这个文件夹，在空白处按住 “shift”键并点击右键，在快捷菜单中选择 “在此处打开 Powershell 窗口”
在命令窗口输入cmd，我们就可以使用youtube-dl来下载视频啦.
比如想下载一个YouTube视频，只需要打开一个YouTube视频地址，复制粘贴后，在命令窗口输入这样的命令：
youtube-dl https://www.youtube.com/watch?v=qVYL7p2L3IQ

按下回车，youtube-dl 就会自动解析网页上的视频，然后默认下载最高画质的视频源到同一个目录下。待到 youtube-dl 提示下载 100% 完成，就可以在本地打开视频观看了。

下载速度超快，不到一分钟，100M的视频就下载好了，你说快不快，比我想象的还要强大。

这是 youtube-dl 最简单的使用方法，它的功能当然不止于此。在 youtube-dl 的官方主页上，详细列出了 youtube-dl 的各种功能以及调用方法。

温馨提示

不仅支持YouTube，还支持其他视频网站，你可以试试pornhub，xvideos之类的成人网站，或许有惊喜哦。

--------------

看到在GitHub上有人据此制作了一个图形界面的YouTube-dl的图形界面应用，免去了输入代码的麻烦，入门门槛极低，非常适合小白，分享给大家。

不仅仅能下载youtube，youtube-dl在线视频下载神器

YouTuBe视频下载方法多种多样，相关的下载工具网上也有很多，比如阿刚之前介绍过的YouTube Video Downloader就是一款使用简便功能强大的下载工具。那么今天再给大家介绍一款轻量级的youtube下载神器–youtube-dl

Youtube-dl是github上的一个开源项目，它是一款轻量级的命令行下载工具。是的，就跟之前介绍的Aria2一样youtube-dl没有GUI图形界面，只有粗糙的命令行。但youtube-dl功能却非常强大，可以直接解析下载youtube多清晰度视频，它还支持包括优酷土豆BBC等国内外上百个视频网站的下载，甚至还支持XXX网站的视频解析与下载，比如Xvideos网上面的小视频…咳咳…..

youtube-dl是一款跨平台多源命令行下载工具，支持Windows、Mac OSX和Linux。阿刚这里简单说下在windows下的安装和使用。

为YouTube-dl创建环境变量

如果你懂Dos命令的话，你可以直接打开CMD使用它，不过为了方便我们可以为其创建环境变量。在Windows系统环境变量Path中填写youtube-dl.exe的路径。例如D:\Program Files\youtube,图中所示为windows10系统环境变量.

环境变量创建之后我们便可以在CMD命令中输入：youtube-dl -h 查看youtube-dl的各项命令。

youtube-dl命令

youtube-dl命令参数较多，输入-h可查看其支持的各种命令，下面是常用的几个参数:

youtube-dl --list-extractors #查看支持网站列表

youtube-dl -U #程序升级

youtube-dl --get-format URL #获取视频格式

youtube-dl -F URL #获取所有格式（目前仅支持YouTube）

命令参数较多，大家可以查看youtube.dl官方说明文档查阅相关命令。阿刚这里以某个MV为例简单说明一下如何使用youtube-dl。

如果视频有多种清晰度可选择，可以使用-F命令获取视频所有的格式。

youtube-dl默认下载质量最优的视频，比如这个视频中直接指明720P为最好（best），虽然视频有1080P的，但youtube默认的1080视频音频与视频分离，所以如果要下载1080P视频，我们需要分别指定视频和音频。比如图中Video ID为137， Audio ID为251，所以下载的命令如下：

youtube-dl -f 137+251 http://www.youtube.com/watch?v=n-BXNXvTvV4

youtube-dl同样可以下载优酷视频，优酷的视频都被分割为多个Flv片段，下载之后需要自己合成，另外-F命令只限于youtube网站，其他视频网站无法通过此命令获取视频的所有格式信息。这一点让人遗憾，不过经测试下载优酷视频可以达到宽带最高下载速度，这点要比国内那些同类软件要优秀的多。

第三方编译版

如果你受不了youtube-dl枯燥乏味的命令行，那么不妨试试下面这款第三方编译后的youtube-DLG，各项设置都一目了然，省去你键入命令行的步骤。你只需粘贴视频地址，即可实现下载。

工具默认选项比较多，基本上包括了youtube-dl常用命令行所能实现的功能，比如默认下载的视频清晰度，转码，以及字幕下载等等。如果你不喜欢命令行操作的话，那么不妨试试这个小工具。

总结

总的来说youtube-dl是款功能强大的在线下载工具，支持上百个全球视频网站的下载，如果你有海外视频下载的需求，youtube-dl绝对是你的首选.

youtube-dl

Youtube-dl是谷歌github上的一个开源项目，它是一款轻量级的命令行下载实用工具，阿刚曾在乐软博客里文章<不仅仅是youtube>一文章，详细介绍过Youtube-dl。

作为一款命令行视频下载神器，Youtube-dl功能强大，可解析下载包括youtube、youku、腾讯视频、爱奇艺等国内外上百个视频网站，它甚至还支持XXX网站的视频解析与下载，比如阿刚经常用它下载XXX片子~~

youtube-dl支持Winodws ，linux和mac平台。安装配置简单，在Windows平台上，你只需下载youtube-dl.exe并为其创建系统变量，就可以通过CMD输入youtube-dl命令来下载视频了。

youtube-dl支持的命令众多，在Github项目主页上大家可以查阅命令，或者直接键入Youtube-dl -h查看帮助说明:

youtube-dl --list-extractors #查看支持网站列表

youtube-dl -U #程序升级

youtube-dl --get-format URL #获取视频格式

youtube-dl -F URL #获取所有格式

youtube-dl -o 输出路径

如果你要下载视频，只需键入命令”youtube-dl +视频地址”

默认情况下，youtube-dl会自动选择下载最高画质。

需要说明的是，一般在线视频网站视频都是被分割成多个小段，youtube-dl下载之后会自动调用ffmpeg来合并视频。如果你没有安装ffmpeg，那么你必须自己合并视频。

FFmpeg是一个自由软件，可以运行音频和视频多种格式的录影、转换、流功能，包含了libavcodec ─这是一个用于多个项目中音频和视频的解码器库，以及libavformat——一个音频与视频格式转换库。

不管是在线流媒体，视频播放/录制，视频转码一般都有ffmpeg的身影，只是由于ffmpeg是命令行工具，有一定学习成本，不被大部分人所知，我们更耳熟能详的是诸如格式工厂之类的音视频转换软件，但实际上格式工厂使用的就是ffmpeg编码技术。
