source .venv/birdnet-stream
pip install -r requirements.txt
```
### Setup systemd services
```bash
# Copy and Adapt templates
services="birdnet_recording.service birdnet_analyzis.service birdnet_miner.timer birdnet_miner.service"
read -r -a services_array <<<"$services"
for service in ${services_array[@]}; do
sudo cp daemon/systemd/templates/$service /etc/systemd/system/
variables="DIR USER GROUP"
for variable in $variables; do
sudo sed -i "s|<$variable>|${!variable}|g" /etc/systemd/system/$service
done
done
# Enable services
sudo systemctl daemon-reload
sudo systemctl enable --now birdnet_recording.service birdnet_analyzis.service birdnet_miner.timer
```
#### Check if services are working
```bash
# Sercices and timers status
sudo systemctl status birdnet_\*
```
```bash
# BirdNET-stream logs
sudo journalctl -feu birdnet_\*

## Setup audio streaming with icecast and ffmpeg for live spectrogram
Install icecast:
```bash
sudo apt-get install icecast2
```
Modify icecast password:
```xml
[...]
<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:
```bash
sudo systemctl enable --now icecast2
```
Adapt `config/birdnet.conf` to this configuration:
```conf
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:
```bash
sudo systemctl enable --now birdnet_streaming.service
```
Add a reverse proxy to nginx to allow https
```nginx
server {
[...]
location /stream {
proxy_pass http://localhost:8000/birdnet;
}
[...]
}
```
## Setup https certificates with dehydrated (only for public instances)
```bash
sudo apt-get install dehydrated
````
Edit `/etc/dehydrated/domains.txt` and add your domain name.
```bash
sudo vim /etc/dehydrated/domains.txt
```
Add acme-challenges alias to your nginx config:
```bash
server {
[...]
location /.well-known/acme-challenge {
alias /var/www/html/.well-known/acme-challenge;
allow all;
}
}
```
Create acme-challenge directory:
```bash
sudo mkdir -p /var/www/html/.well-known/acme-challenge
```
Adapt `/etc/dehydrated/config`, by adding this folder to the `WELLKNOWN` path:
```bash
WELLKNOWN = "/var/www/html/.well-known/acme-challenge"
```
Register to certificate issuer and accept conditions and terms:
```bash
dehydrated --register --accept-terms
```
Generate certificates:
```bash
dehydrated -c
```
Add dehydrated cron
```bash
sudo crontab -e
```
```bash
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:
```bash
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:
```bash
# 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](https://birdnet.lan/ttyd) and start streaming logs.
