ComfyStream WebRTC C++ Client

This repository contains my test code for connecting an C++ WebRTC client to an python WebRTC server.

Prerequisites

• Python 3.11
• Conda
• CMake
• Build Essentials (for Linux)
• nlohmann_json
• LibDataChannel
• OpenCV
• FFmpeg

Testing Instructions

1. Set up a Python environment and install dependencies:

   conda create -n webrtc_test python=3.11
   conda activate webrtc_test
   pip install -r requirements.txt

2. Start the Python WebRTC server:

   python3 webrtc_server.py

3. Verify WebRTC functionality by opening index.html in a browser and ensuring the JavaScript example runs without issues.

4. Close the browser and restart the WebRTC server:

   python3 webrtc_server.py

5. Install the Libdatachannels library: Follow the instructions from the LibDataChannel GitHub repository to install LibDataChannel.

6. Install C++ Dependencies:

   sudo apt-get install nlohmann-json3-dev
   sudo apt-get install libopencv-dev
   sudo apt-get install libavcodec-dev libavformat-dev libavutil-dev libswscale-dev
   sudo apt install build-essential

7. Compile the C++ client by installing the required build tools and using CMake:

   cmake .
   cmake --build .

8. Run the C++ client:

   ./webrtc-client

9. Observe that C++ client communication is broken: Despite data being sent, the recv method of MediaStreamTrack is never triggered.
