DESCRIPTION

nextdl is a 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 macOS. It is released to the public domain, which means you can modify it, redistribute it or use it however you like.

--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 nextdl 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.
--ignore-config                      Do not read configuration files. When

                                     proxy. To enable SOCKS proxy, specify a
                                     proper scheme. For example
                                     socks5://127.0.0.1:1080/. Pass in an
                                     empty string (--proxy "") for direct

Geo Restriction:

--geo-verification-proxy URL         Use this proxy to verify the IP address
                                     for some geo-restricted sites. The
                                     default proxy specified by --proxy (or
                                     none, if the option is not present) is
                                     used for the actual downloading.
--geo-bypass                         Bypass geographic restriction via

--geo-bypass-ip-block IP_BLOCK       Force bypass geographic restriction
                                     with explicitly provided IP block in
                                     CIDR notation

Video Selection:


NUMBER (like “comment_count > 12”, also works with >=, <, <=, !=, =) to compare against a number, key = ‘LITERAL’ (like “uploader = ‘Mike Smith'”, also works with !=) to match against a string literal and & to require multiple matches. Values which are not known are excluded unless you put a question mark (?) after the operator. For example, to only match videos that have been liked more than 100 times and disliked less than 50 times (or the dislike functionality is not available at the given service), but who also have a description, use –match-filter “like_count > 100 & dislike_count

--playlist-start NUMBER              Playlist video to start at (default is
                                     1)

                                     last)

                                     playlist-items 1,2,5,8" if you want to
                                     download videos indexed 1, 2, 5, 8 in
                                     the playlist. You can specify range: "
                                     --playlist-items 1-3,7,10-13", it will
                                     download the videos at index 1, 2, 3,
                                     7, 10, 11, 12 and 13.

                                     (see the "OUTPUT TEMPLATE" for a list
                                     of available keys) to match if the key
                                     is present, !key to check if the key is

                                     put a question mark (?) after the
                                     operator. For example, to only match
                                     videos that have been liked more than
                                     100 times and disliked less than 50

                                     not available at the given service),
                                     but who also have a description, use

CONFIGURATION

You can configure nextdl by placing any supported command line option to a configuration file. On Linux and macOS, the system wide configuration file is located at /etc/nextdl.conf and the user wide configuration file at ~/.config/nextdl/config. On Windows, the user wide configuration file locations are %APPDATA%\nextdl\config.txt or C:\Users\ \nextdl.conf . Note that by default configuration file may not exist so you may need to create it yourself.

For example, with the following configuration file nextdl will always extract the audio, not copy the mtime, use a proxy and save all videos under Movies directory in your home directory:

# Lines starting with # are comments

# Always extract audio
-x

# Do not copy the mtime
--no-mtime

# Use this proxy
--proxy 127.0.0.1:3128

# Save all videos under Movies directory in your home directory
-o ~/Movies/%(title)s.%(ext)s

Note that options in configuration file are just the same options aka switches used in regular command line calls thus there must be no whitespace after - or --, e.g. -o or --proxy but not - o or -- proxy.

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

You can also use --config-location if you want to use custom configuration file for a particular nextdl 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 nextdl execution and prevent tracking plain text passwords in the shell command history. You can achieve this using a .netrc file on a per extractor basis. For that you will need to create a .netrc file in your $HOME and restrict permissions to read/write by only you:

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

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

<div class="snippet-clipboard-content position-relative overflow-auto" data-snippet-clipboard-copy-content="machine login password ">

machine 
        
          login 
         
           password
