Setup audio streaming with icecast and ffmpeg for live spectrogram

Install icecast:

sudo apt-get install icecast2

Modify icecast password:

[...]
<authentication>
    <!-- Sources log in with username 'source' -->
    <source-password>secret</source-password>
    <!-- Relays log in with username 'relay' -->
	<relay-password>secret</relay-password>
    <!-- Admin logs in with the username given below -->
    <admin-user>birdnet</admin-user>
    <admin-password>secret</admin-password>
</authentication>
[...]

Launch and enable icecast:

sudo systemctl enable --now icecast2

Adapt config/birdnet.conf to this configuration:

ICECAST_USER=source
ICECAST_PASSWORD=secret # change this to the password you set above
ICECAST_PORT=8000
ICECAST_HOST=localhost
ICECAST_MOUNT=stream

Launch and enable audio streamer daemon:

sudo systemctl enable --now birdnet_streaming.service

Add a reverse proxy to nginx to allow https

server {
    [...]

    location /stream {
        proxy_pass http://localhost:8000/birdnet;
    }

    [...]
}

Setup https certificates with dehydrated (only for public instances)

sudo apt-get install dehydrated

Edit /etc/dehydrated/domains.txt and add your domain name.

sudo vim /etc/dehydrated/domains.txt

Add acme-challenges alias to your nginx config:

server {
    [...]

    location /.well-known/acme-challenge {
        alias /var/www/html/.well-known/acme-challenge;
        allow all;
    }
}

Create acme-challenge directory:

sudo mkdir -p /var/www/html/.well-known/acme-challenge

Adapt /etc/dehydrated/config, by adding this folder to the WELLKNOWN path:

WELLKNOWN = "/var/www/html/.well-known/acme-challenge"

dehydrated --register --accept-terms

Generate certificates:

dehydrated -c

Add dehydrated cron

sudo crontab -e

00 00 01 * * dehydrated -c

(This updates the certicates every first day of the month, feel free to adapt to your needs.)

Setup ttyd to stream audio to webapp

Change to a dedicated folder, build and install ttyd:

cd /opt
sudo wget wget https://github.com/tsl0922/ttyd/releases/download/1.7.1/ttyd.x86_64 # Change to your architecture and get last version
sudo mv ttyd.x86_64 ttyd
sudo chmod +x ttyd

Set up birdnet_ttyd systemd service to start as a daemon:

# Copy service template
sudo cp ./daemon/systemd/templates/birdnet_ttyd.service /etc/systemd/system/birdnet_ttyd.service
# Edit template and adapt placeholders
sudo vim /etc/systemd/system/birdnet_ttyd.service
# Enable and start ttyd service
sudo systemctl daemon-reload
sudo systemctl enable --now birdnet_ttyd.service

Then go to https://birdnet.lan/ttyd and start streaming logs.
