[FaceAI2025]

Successful run demo on Android Device , but

RtspDataListener,onRtspDataApplicationDataReceived never call back;

    private val rtspDataListener = object: RtspDataListener {
        override fun onRtspDataApplicationDataReceived(data: ByteArray, offset: Int, length: Int, timestamp: Long) {
                // nerver call back
        }
    }

we need call back data for real time AI analysis, what the best way? thank you.

onRtspDataApplicationDataReceived() is called only for RTSP devices which support application data. Usually application data contains metadata, e.g. GPS coordinates and so on. Majority of RTSP cameras do not support it.

If you want image processing, you need to use RtspImageView class which allows obtaining bitmap data.
