## 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.)
