What's the best way to have BirdNet-Go start on boot up, but in a terminal window rather than as a background service?

Depends on a OS I guess, but why you need to start in terminal window instead of background service?

Raspberry Pi OS. In a terminal window to see what is going on with a quick glance via VNC e.g. dog -> owl false positive rejection.

Okay, in this case I would still start birdnet-go as a service, you can follow console output with journalctl.

Create a systemd config file /etc/systemd/system/birdnet-go.service, below is a config template you can use

[Unit]
Description=BirdNET-Go Analyzer Service

[Service]
ExecStart=/home/thakala/birdnet-go realtime
Restart=on-failure
User=thakala
Group=thakala
WorkingDirectory=/home/thakala

[Install]
WantedBy=multi-user.target

Replace User, Group, ExecStart and WorkingDirectory to match your system.

To reload systemd config run

# systemctl daemon-reload

Enable birdnet-go service start on boot run (systemctl start birdnet-go will start it on demand)

# systemctl enable birdnet-go

And to follow console output with journalctl run

# journalctl -t birdnet-go -f

-t matches logs from birdnet-go process, -f keeps following output and prints all log messages as they are received from birdnet-go

Not sure if this is best practice, but I set my docker container to always run which will automatically restart it on a crash or a system reboot. Added this to the runtime command.
--restart=always

Another option is --restart unless-stopped.

Always is fine too, but if you restart the Docker daemon the container will restart if you've manually stopped it.
details here - https://docs.docker.com/config/containers/start-containers-automatically/

The unzipped files are loacted here: /home/tom/birdnet

File /etc/systemd/system/birdnet-go.service contains:

[Unit]
Description=BirdNET-Go Analyzer Service

[Service]
ExecStart=/home/tom/birdnet/birdnet-go realtime
Restart=on-failure
User=tom

WorkingDirectory=/home/tom/birdnet

[Install]

Works perfectly fine if I run ./birdnet-go realtime from the install folder.

Although your provided log lines are truncated and are missing some key information, (code=exited, status=200/CHDIR) indicates that your working directory setting is incorrect. Please check your install directory path.

That's the full log. And /home/tom/birdnet is the correct directory.

Is there a permission problem for the soundcard?

It's been a while, so I don't know if I was having the exact same problem, but I also was having a bunch of weird permissions issues when trying to set up a systemd service for this. Once the work on Docker deploys started, I didn't spend any more time on it because once things stabilize I will likely use that. For now I've just been running birdnet-go realtime &. I check the web UI often enough that I notice pretty quickly if it's gone down. But I tried a whole bunch of different things (sudo, not sudo, keeping it in /opt vs /home, different users and groups, etc) and never got it working the way I wanted. But I also don't know my way around systemd very well, so I may have been missing something very obvious.

@tomlut thank you, now there is enough logs so I was able to debug, I installed full RPI OS and was able to reproduce this. Problem is caused by Raspberry PI's integrated sound device and fact that you have full Raspberry Pi install, I have not hit this as I am using RPi OS Lite install and by habit I always disable unused devices, which is kind of poor practice when you try to develop something for others to use ..

There are few fixes, if you do not need Raspberry Pi's audio playback just disable onboard audio devices. Edit /boot/firmware/config.txt

change dtparam=audio=on to off

dtparam=audio=off

add noaudio to dtoverlay=vc4-kms-v3d

dtoverlay=vc4-kms-v3d,noaudio

and reboot.

If you need to use onboard audio playback add create .asoundrc file in your home director (/home/tom) and add following content

pcm.!default {
  type asym
  playback.pcm {
    type plug
    slave.pcm "hw:0,0"
  }
  capture.pcm {
    type plug
    slave.pcm "hw:2,0"
  }
}

ctl.!default {
  type hw
  card 2
}

This will make second audio card (which should be your USB Sound Card) as default capture device.

I will try to fix birdnet-go code so that it would always prefer USB Sound Card's over RPI sound device.

I do not need audio so I gave the first option a go.

Worked perfectly. Thank you. 👍
