An example `liquidsoap` configuration file with two input streams and two output streams to `icecast`.

liquidsoap.liq

#!/usr/bin/liquidsoap

# Activate the live stream input
set('harbor.bind_addr', '0.0.0.0')

# Configure input A
input_a = input.harbor(
    'input_a',
    port=8001,
    password='bigproblem'
)

# Configure input B
input_b = input.harbor(
    'input_b',
    port=8002,
    password='bigproblem'
)

# Send input A to icecast
output.icecast(
    %mp3(bitrate=192),
    input_a,
    host=getenv('ICECAST_HOST'),
    port=int_of_string(getenv('ICECAST_PORT')),
    password=getenv('ICECAST_SOURCE_PASSWORD'),
    mount='stream-a.mp3',
    name='',
    genre='',
    description='',
    url='',
    fallible=true
)

# Send input B to icecast
output.icecast(
    %mp3(bitrate=192),
    input_b,
    host=getenv('ICECAST_HOST'),
    port=int_of_string(getenv('ICECAST_PORT')),
    password=getenv('ICECAST_SOURCE_PASSWORD'),
    mount='stream-b.mp3',
    name='',
    genre='',
    description='',
    url='',
    fallible=true
)

Please do, someday I would like to have working examples with local media files in a repository.
