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.fm/
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-pervasives
- Do not load pervasive script libraries.
- --version
- Display liquidsoap's version.
- -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.
- --conf-descr-key key
- Describe a configuration key.
- --conf-descr
- Show all configuration keys with their documentation.
- --conf-descr-liqi
- Show all configuration keys with their documentation in liqi
(documentation wiki) format.
- --conf-dump
- Dump the configuration state
- -help, --help
- Display this list of options
