I installed liquidsoap in Ubuntu 20.04, and querying the plugins, it looks like the output.shoutcast plugin is missing. It was working when I was on Ubuntu 18.04.
# which liquidsoap
/usr/bin/liquidsoap
# liquidsoap -h output.shoutcast
Plugin not found!
# liquidsoap --list-plugins-xml | grep -o "<label>output\..*"

Description: audio streaming language
Liquidsoap is a powerful tool for building complex audio streaming systems,
typically targeting internet radios (e.g. icecast streams).
.
It consists of a simple script language, in which you can create, combine and
transform audio sources. Its design makes liquidsoap flexible and easily
extensible.
.
Some of the typical uses are:
* dynamically generating playlists depending on the time or other factors
* having smooth transitions between songs
* adding jingles periodically
* applying effects on the sound like volume normalization
* reencoding the stream at various qualities
* remotely controlling the stream
