This repository contains the TLIS streamserver in the form of Docker microservices. It is composed of the following containers:

1. Icecast (audio stream server)
2. Liquidsoap (fallback stream generator)
3. Filebrowser (for managing fallback audio files)

Start the server using docker compose up.

The Icecast web interface is exposed on host port 8000. On port 8080, you will find a simple web-based fileserver which you can use to upload music and jingles for the fallback stream.

First, it is necessary to open the fileserver web interface, login as admin:admin and change the default admin password. It is also recommended to create a non-admin user, which should then be used to manage the audio files.

NOTE: Do not change the folder structure! Only upload/modify/delete music files in the existing directories. There is a single directory for jingles and 4 directories for different time segments of the day.

NOTE: Until you upload some music files, the fallback stream will be up but you will only hear a test tone and white noise.

• 8000: icecast web interface, also used for publishing audio (streaming from studio)
• 8080: filebrowser

• fallback-music volume is shared between liquidsoap and filebrowser

• explore better ways to manage icecast passwords in this project
• idea for a v2: for switching between studio and fallback, use the liquidsoap script. This should result in smoother changeovers, also there would always be exactly 1 public-facing active icecast mountpoint. This would also simplify listener count logging.
  • current icecast mountpoint order: tlis > studio > fallback
  • proposed mountpoint order: tlis > mix > live > studio
    • liquidsoap takes live and studio as inputs, generates fallback and outputs to mix. If liquidsoap (mix) fails, icecast will automatically switch to live or studio, if they're up.
