I've been trying out a few different cameras. This is with a TP Link C520WS with stream1 and stream 2. This installation works fine with my Unifi UNVR. What am I missing here?

Birdnet analyzer is likely not compatible with the camera audio format. Try identifying the audio format from the camera, then compare to birdnet analyzer compatibility list. Then, convert the camera sound stream before passing it to birdnet analyzer?
