Testing alongside BirdNET-Pi

[farski]

Hi @tphakala

How feasible is it to test this alongside BirdNET-Pi on the same Pi? I assume it should be fine, but I haven't seen an obvious way to set the web port, so that may be the only thing that conflicts.

I only have one Pi at the moment that I can get actual results with, but if I can get this running on there I can probably help out with some UI work.

Thanks for all your work on this

Hi, yes I think you can share same RPI with BirdNET-Pi and BirdNET-Go. On BirdNET-Go web server port is configurable, it defaults to 8080 which will not conflict with BirdNET-Pi.

[tphakala]

Config file changes over versions are not handled well, or at all at the moment. Locale setting has indeed moved to birdnet node, and if you have config file created by older version app startup fails. Please backup old config file to another location and let birdnet-go to create new config file, after that you can reconfigure defaults with your specific settings and it should work.

Tflite library is indeed 64-bit only, provided file should work on RPI 3 with 64-bit OS, at least I have been using it successfully, although by current dev system is RPI 5 with latest RPI OS.

Can you give a hint where to configure the webserver. Birdnet-Go seems to run fine aside of birdnet-pi on an Raspberry 3b, but no webserver is running, and the debug output says also nothing about.

[Shellfishgene]

Did you compile from source? The current binaries don't have the webserver yet.

[Smo-RBR]

ah, okay. I fiddled around in the code, added the config for the webserver in config file, and nothing happened :)

[tphakala]

New binary release for RPI containing web ui is now uploaded to releases section

actually testing BirdNET-Pi and birdnet-go in parallel on a raspberry Pi4 (8G RAM).
I'm listenig live with BirdNET-PI, birdnet-go does realtime analysis (-t 0.1 in order to increase biodiversity in my backyard ;)
System load is about 1.5, processing time as reported by birdnet-go is about 200 - 300ms
nice!

Finally got a chance to spend some time on this, here's some notes mostly for myself, but may be useful for other early testers:

• Set up a fresh Bookworm Lite 64 bit SD card
• Grabbed the 20240215 snapshot
• Installed pulseaudio via apt (had to reboot to get that working) and set the pulse daemon config
• Set lat/long in the BirdNET config file
• birdnet-go realtime was giving me a bunch of SoX not found errors trying to generate spectrograms, so I also did apt install sox, but now I have SoX command failed errors instead

I also tried to make the following systemd service

[Unit]
Description=BirdNET-Go realtime analysis
After=network.target
StartLimitIntervalSec=0

[Service]
Type=simple
Restart=always
RestartSec=5
User=birdnet
ExecStart=/home/birdnet/birdnet-go realtime

[Install]
WantedBy=multi-user.target

I very rarely use systemd, so I'm pretty bad at it, but not matter what I did trying to run birdnet-go through there resulted in open webui.log: permission denied

Going to let it run over the weekend, will report back.

Any news on comparison? Performance wise?

First of all, awesome work here, so great to see an actively developed - and improving - instance for BirdNET.

Quick question on BirdNET-Pi / birdnet-go dual setup: how are guys configuring pulse or sox or whatever to send the mic to both? I'm fine on http/UI end, that was easy, can't figure the sound piece.

[tphakala]

There indeed seems to be issues with sharing sound device between BirdNET-Pi services and BirdNET-Go, problem @farski reported is this exact issue. I will try to solve this.

[unosonic]

it would be really helpful if one could choose a specific ALSA source, in case you have several input devices present.
so far I have configured a virtual alsa pcm device like this in /etc/asound.conf

pcm.birdmic {
    type dsnoop
    ipc_key 1234
    ipc_key_add_uid false
    ipc_perm 0666
    slave {
        pcm "hw:MYHARDWARESOUNDCARDID"   # your actual device
        channels 2
        rate 48000
        period_size 1024
        buffer_size 4096
    }
}
pcm.!default
{
    type asym
    playback.pcm
    {
        type plug
        slave.pcm "dmix"
    }
    capture.pcm
    {
        type plug
        slave.pcm "birdmic"
    }
}

that way I can choose "birdmic" in birdnet-pi and it also works in birdnet-go, since I've made it the default ALSA source.

[tphakala]

@DMontgomery40 I did a lot of testing today and found root cause of issues, please see my reply at #37.

@unosonic I agree, I need to study how ALSA source can be set in malgo (miniaudio go library).

[DMontgomery40]

Awesome thanks!! I was actually just going to update that this fixed it for me, and then just saw your solution, the .asoundrc is a bit more elegant but now I'm scared to tough anything since it's working

in the screenshot below, that is the dsnoop device, had no idea i could just write "dsnoop" !

[unosonic]

I've had no success in using dsnoop device directly, it did not work for shared mic access, no idea why. But I'm using this custom dsnoop as described above successfully on several raspberry pi zeros, also together with pulseaudio. /etc/pulse/default.pa:
load-module module-alsa-source device=birdmic
