RTSP Streaming

[hpk60]

As a mobile device, I set up a Raspberry Pi 0W as RTSP device. It connects over VPN to my home network, where I can hear the stream as follows: rtsp://192.168.5.206:8554/mic
When I add this to the config under RTSP stream URLs and then try to listen the stream on birdnet-go, I get a 404 html error.
What else do I need to configure, that I can use an RTSP Stream instead of the local mic?

VLC Player shows:

Codec: MPEG AAC Audio
Typ: Audio
Channels: Stereo
Rate: 48000 Hz
Bits: 32

can you please share a screenshot of Audio Settings page and error you are seeing?

Hi Tomi (@tphakala),

thanks for answering so fast! Here it is:

The error pops up, as soon as I click the microphone and chose the green start button to play the rtps stream

That is odd. Could you send a support bundle from Settings > Support > [Generate & Upload] button so I could take a look at logs what is happening

you'll have it:

I sent you the access informations, @tphakala you can login and have a look

Got it thanks, I do see same 404 error: "Server returned 404 Not Found". Looking at your screenshot and your error description IP address of RTSP server should be 192.168.5.206 but in logs it is rtsp://192.168.5.205:8554 (note 205, not 206). Remove RTSP URL and add it again with correct IP, I think there may be a UI bug which allows you to edit IP of already configured RTSP stream but it is not really applied.

Sorry about that. This afternoon, when I tested, I did it with another birdnet-go Raspi, and I sent you the log.
This evening, I started a test device to debug and let you see, what happens. However, RTSP Server is definitely 192.168.5.206, 205 was a test system a few days ago. Here how it is running at the moment:

You might have a look at birdnetgo1 I sent you the URL and settings password to access it via internet.
Thanks for your help, @tphakala

Yes I believe you that 192.168.5.206 is the correct RTSP server, but BirdNET-Go (or FFmpeg which it is using for RTSP connection) is trying to connect to 205 instead. Please reconfigure RTSP URL in BirdNET-Go and remember to save settings.

I just deleted the rtsp link and reentered it again, restartet birdnetgo raspi, but still html 404 error.

That's really odd. 205 was a test a few days ago, that was not successful. so I started from scratch and built up a new RTSP streamer, with a new IP (206). And, as you can see on the screenshot with the error message above, birdnetgo1 has configured 206.

same is true, when I look at the config.yaml file:

rtsp:
    transport: tcp
    urls:
        - rtsp://192.168.5.206:8554/mic
    health:
        healthydatathreshold: 60
        monitoringinterval: 30
    ffmpegparameters: []

So I guess, reconfiguring in the birdnetgo app, does not reconfigure ffmpeg?

Where can I change the ffmpeg settings, @tphakala ?

[hpk60]

Okay, I did a fresh installation to get rid of any false config infos from the testing phase and chose rtsp stream right from the beginning.
Now, everything is running as it should!
Thanks for your support.

Another information:
I can connect to birdnet-go rPI locally or through a proxy server. Locally (192.168.5.114:8080), I can listen to the stream, when I connect through the proxy (birdnetgo.myurl.com) I cannot listen to the stream. But that's a proxy issue, not a birdnet-go one.
Just in case someone faces the same issue.

One more question: Using rtsp, on birdnet-go rPI 4B the CPU goes up to ~85%. Are there optimized settings for balancing the load between the rtsp streamer and birdnet-go? What is the optimal codec to use on the rtsp server for birdnet-go?
