Web RTC Project (Zoom Video Clone)
Link to the GitHub repository: https://github.com/eelviral/Real-Time-Video-Streaming
In today's world, real-time communication stands at one of the many forefronts of innovation. This WebRTC Project, inspired by Zoom Video, is my own testament to real-time video technology.
My primary goal in this project, is to harness the power of WebRTC, and to demonstrate its capability in creating instant video communication that is both seamless and high-quality. WebRTC's true potential goes beyond simple video chats; it can drastically benefit sectors like robotics, where real-time commands and feedback loops are crucial.
Embracing WebRTC also doesn't just mean better video calls; it demonstrates a shift where distance becomes irrelevant, collaboration becomes easier than ever, and our shared digital experiences become more authentic.
Join me, as I guide you through the technical side of my project, and demo the end result.
Key Code Snippets
From ‘server.py’
In the server.py script, the core functionality revolves around the BallStreamTrack class, which represents a video stream of a bouncing ball.
Derived from VideoStreamTrack, this class initializes the attributes of the ball, handles its motion, manages boundary collisions, and randomizes its color upon each collision. The motion and color changes are visualized using OpenCV.
The run() asynchronous function facilitates the WebRTC connection, awaiting client connections and orchestrating the offer-answer handshake for streaming.
This script essentially establishes the server-side infrastructure to transmit a dynamic ball video feed to connected clients using the aiortc library and Python's asyncio capabilities.
From ‘client.py’
For the client.py script, the central component is the BallTransformTrack class, which inherits from MediaStreamTrack.
This class is prepped to receive and display video frames of a bouncing ball sent by the server. When initialized, the class takes in a track, which it uses in the asynchronous recv() method to obtain video frames from the server.
The received frames are then converted and displayed with OpenCV. The run() asynchronous function sets up the WebRTC connection to the server.
Through the WebRTC offer-answer protocol, the client awaits an offer from the server, responds with an answer, and establishes a video stream connection. This script solidifies the client-side logic that receives and displays a dynamic ball video feed streamed from the server using the aiortc library and Python's asyncio framework.
Transmitting our Video Feed with WebRTC
Below, you'll find a demo showcasing the initial test of the application. This test mainly aims to examine the app’s video communication capability. Following this, there's a demonstration of the completed application, illustrating the fully realized features and functionalities of our WebRTC project.
Testing the Program
In the initial stages of this project, it’s very important for us to make sure that there is effective transmission of video data between the server and the client. What you see below is a gif demonstration of this very test, where the video feed transitions through a gradient—from black to gray, and then, to white. This first video test served as a confirmation that the WebRTC app is capable of real-time video transmission.
This successful test gave me the green light to advance to the next stages, which includes the implementation of the slightly more complex 'bouncing ball' video. While this current demo doesn't showcase the bouncing ball, it represents a pivotal step in our journey towards achieving that goal.
The Finished Program
Below is a gif showcasing the successful implementation of the bouncing ball video, transmitted seamlessly between the server and the client. This demo highlights the capabilities of the WebRTC application and marks the successful accomplishment of our project's primary goal.
Wrapping Up…
In reflecting upon this project, I've tapped into the transformative potential of WebRTC. This project, inspired by giants like Zoom Video, serves as more than just a mere technological showcase—it highlights the beginning of a world where digital communication is completely seamless and makes way for instant and genuine interactions.
