Debian 12 Linux Radio stream (rtmp) (Opam, gd, ffmpeg, Liquidsoap)

In this guide, we will create our own Internet radio and start broadcasting it on Youtube or Rutube (RTMP), add background animation and prepare a playlist. In this guide, we are installing as root, if you have a normal one, use the sudo command. You can order a ready-made server with this configuration on the VPS server order form.

Most frequently asked questions:

A fragment of the result of this configuration:

1. Install the necessary packages:

apt update
apt upgrade
apt-get install libfreetype6-dev
apt-get install opam
opam init

eval $(opam env)

opam switch create cs3110-2022fa ocaml-base-compiler.4.14.0

eval $(opam env)

opam depext gd ffmpeg liquidsoap
opam install gd ffmpeg liquidsoap

eval $(opam env)

2. Create folders for music, background video:

mkdir /home/radio
mkdir /home/radio/music

3. Let's create a configuration file for the radio station itself:

nano /home/radio/radio1.liq

# permission to run the script from the root user
settings.init.allow_root.set(true)

# metadata functions
song_author = ref('')
def apply_song(m) =
song_author := m["artist"]
end

song_title = ref('')
def apply_song2(m) =
song_title := m["title"]
end

def get_track_name_text()
"$(artist) - $(title)" % [ 
("artist", song_author()),    
("title", song_title())
]
end 

# audio source
audio = playlist(reload_mode="watch", "/home/
radio/music
")
audio = mksafe(audio)

# video source (gif, mp4)
background = single("/home/radio/
background.gif
")

# add logo
background = video.add_image(x=1120, y=20, width=153, height=56, file="/home/radio/
logo.png
", background)

# calling metadata
audio.on_track(apply_song) 
audio.on_track(apply_song2) 

# drawtext
background = video.add_text(color=0xFFFFFF, font="/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf", speed=0, x=50, y=50, size=26,
get_track_name_text,
background)

# mixing sources
radio = mux_video(video=background, audio)

#rtmp+codec
url = "rtmp://
Address and key from the streaming platform via RTMP protocol
"
enc = %ffmpeg(format="flv",
%video(codec="libx264", width=1280, height=720, pixel_format="yuv420p",
b="750k", maxrate="750k", minrate="750k", bufsize="1500k", profile="Main", preset="veryfast", framerate=30, g=60),
%audio(codec="aac", samplerate=44100, b="128k"))

# output
output.url(fallible=true, url=url, enc, radio)

3.1 Specify the URL variable depending on the service where you will be broadcasting:

Youtube

url = "rtmp://a.rtmp.youtube.com/live2/
Key generated by Youtube
"

Rutube

url = "rtmp://rtmp-1.brz.rutube.ru/live_push/
Key generated by Rutube
"

VK

url = "rtmp://ovsu.mycdn.me/input/
Key generated by VK
"

3.2 Check in the configuration file that the path is correct as the music folder and place your music files there, the reload_mode="watch" option says that as soon as a new file appears in the folder, it will be immediately added to the playback queue.

audio = playlist(reload_mode="watch", "/home/
radio/music
")

3.3 Specify the correct path for broadcasting video background:

background = single("/home/radio/
background.gif
")

It can be a static png, jpg picture or video animation gif, mp4. The background animation file is looped.

3.4 Specify the correct path for your channel's logo file:

background = video.add_image(x=1120, y=20, width=153, height=56, file="/home/radio/
logo.png
", background)

Edit the size and position as needed.

4. Starting the radio and checking operation:

cd /home/radio
liquidsoap radio1.liq

The processing log will appear and if there are no errors, the translation is successful, go to the page where you created it and check the work.

4.1 Creating and auto-starting a service:

cd /home
apt install git
git clone https://github.com/savonet/liquidsoap-daemon.git
cd /home/liquidsoap-daemon
./daemonize-liquidsoap.sh /home/radio/radio1.liq

4.2 Commands:

Start

systemctl start radio1-liquidsoap

Stop

systemctl stop radio1-liquidsoap

Status

systemctl status radio1-liquidsoap

Our radio is ready, you can see what happened in the video example before starting the setup. This protocol is supported by a large number of popular services.
