LIQUIDSOAP(1)

NAME
liquidsoap - a multimedia streaming language

SYNOPSIS
liquidsoap [ options ] [ script | expression ]

DESCRIPTION
Liquidsoap is a programming language for describing multimedia streaming systems. It is very flexible, making simple things simple but giving a lot of control for advanced uses. Liquidsoap supports audio, video and MIDI streams, and a wide range of input/output operators including Icecast and various soundcard APIs. It can perform a broad range of signal processing, combine streams in various ways, support custom transitions, generate sound procedurally... and all this can be assembled as you wish. Input files can be accessed remotely, or even be synthesized on the fly using external scripts such as speech synthesis. Finally, interaction with a running liquidsoap instance is possible via telnet or socket.

Liquidsoap scripts passed on the command line will be evaluated: they shall be used to define the streaming system to be ran. It is possible to pass multiple scripts; they will all be ran successively, and definitions from one script can be used in subsequent ones. A script will be read from standard input if - is given as script filename. Information about scripting liquidsoap is available on our website: http://liquidsoap.info/ .

If the parameter is not a file it will be treated as an expression which will be executed. It is a convenient way to test simple one-line scripts. When running only one-liners, the default is to log messages directly on stdout rather than to a file.

OPTIONS

-   Read script from standard input.

--  Stop parsing the command-line and pass subsequent items to the script.

--debug
    Print debugging log messages.

--dynamic-plugins-dir path
    Directory where to look for plugins.

--errors-as-warnings
    Issue warnings instead of fatal errors for unused variables and ignored expressions. If you are not sure about it, it is better to not use it.

--interactive
    Start an interactive interpreter.

--list-plugins
    List all plugins (builtin scripting values, supported formats and protocols).

--list-plugins-xml
    List all plugins (builtin scripting values, supported formats and protocols), output as XML.

--no-stdlib
    Do not load pervasive script libraries.

--version
    Display Liquidsoap’s version.

--build-config
    Display Liquidsoap’s build config.

-c, --check
    Check and evaluate scripts but do not perform any streaming.

-cl, --check-lib
    Like --check but treats all scripts and expressions as libraries, so that unused toplevel variables are not reported.

-d, --daemon
    Run in daemon mode.

-f, --force-start
    For advanced dynamic uses: force liquidsoap to start even when no active source is initially defined.

-h plugin
    Print the description of a plugin, eg. a builtin scripting function.

-i  Display inferred types.

-p, –parse-only
    Parse scripts but do not type-check and run them.

-q, --quiet
    Do not print log messages on standard output.

-r filename
    Process a request.

-T, --disable-telnet
    Disable the telnet server.

-U, --disable-unix-socket
    Disable the unix socket.

-t, --enable-telnet
    Enable the telnet server.

-u, --enable-unix-socket
    Enable the unix socket.

-v, --verbose
    Print log messages on standard output.

--list-settings
    Show all settings with their documentation.

-help, --help Display this list of options
