Audio Streaming to ONVIF Camera

This project allows you to stream audio from your microphone to an ONVIF-compatible IP camera using RTP (Real-time Transport Protocol). It sets up the camera to enable audio output and handles audio capture, encoding, and transmission in real-time.

Features

• Connects to an ONVIF camera and configures it for audio streaming.
• Captures audio from the microphone.
• Sends audio data over RTP to the camera.
• Allows toggling audio output on the camera via HTTP requests.

Prerequisites

Before running this script, ensure you have the following prerequisites installed:

• Python 3.x
• requests
• onvif-zeep
• pyaudio
• numpy
• msvcrt (Windows only, used for keyboard input detection)

You can install the necessary packages using pip:

pip install requests onvif-zeep pyaudio numpy

Configuration

Update the following configuration variables in the script as per your setup:

• host: IP address of the ONVIF camera.
• port: Port number for the ONVIF camera (usually 80).
• username: Username for the camera.
• password: Password for the camera.
• client_ip: IP address of the client machine from which you are running the script.

Usage

1. Ensure the ONVIF camera is connected and accessible over the network.
2. Run the script:

   python audio_streaming_to_onvif_camera.py

3. The script will:
   • Connect to the camera and configure it for audio streaming.
   • Capture audio from the microphone.
   • Send the encoded audio data to the camera via RTP.

Notes

• The script uses the msvcrt module for detecting keyboard input, which is specific to Windows. Modify this part if running on a different operating system.
• Adjust the sleep time in the main loop (time.sleep(0.02)) if necessary to match the audio capture rate and transmission timing.
