[alishe79]

I wanna send audio to unv or any vendor camera support play sound in camera. easy_onvif support this ? if yes, how can i stream audio to camera using easy_onvif ?

Hello @alishe79,

This library and Onvif in general does not have any direct support for sending audio to a device.

You can use easy_onvif to get the RTSP audio stream uri, then you'll have to find another library to send or receive audio on that stream. Here's some sample code in c-sharp that i was able to find - how-to-send-audio-on-rtsp-backchannel

You might also be able to test sending an audio stream to the device with the command line tool - ffmpeg

@faithoflifedev my default class, use mobile microphone .

        try {
            classifier = AudioClassifier.createFromFileAndOptions(context, currentModel, options)
            tensorAudio = classifier.createInputTensorAudio()
            recorder = classifier.createAudioRecord()
            startAudioClassification()
        } catch (e: IllegalStateException) {
            listener.onError(
                "Audio Classifier failed to initialize. See error logs for details"
            )

            Log.e("AudioClassification", "TFLite failed to load with error: " + e.message)
        }
