Audio, video and data channel server

This repository is an example of working with WebRTC and WebSockets using different development stacks. The examples implement the transmission of video, audio and data channel to the server and their reverse transmission to the client. It also performs some image processing on the video frames using OpenCV.

Running

First install the required packages:

$ pip install aiohttp aiortc opencv-python

When you start the example, it will create an HTTP server which you can connect to from your browser:

$ python server.py

You can then browse to the following page with your browser:

http://127.0.0.1:8080

Once you click Start the browser will send the audio and video from its webcam to the server.

The server will play a pre-recorded audio clip and send the received video back to the browser, optionally applying a transform to it.

In parallel to media streams, the browser sends a 'ping' message over the data channel, and the server replies with 'pong'.

Additional options

If you want to enable verbose logging, run:

$ python server.py -v
