An intriguing exploration of building a video chat application with Snapchat-like filters, this text details the use of Jeeliz for AR filters and the 100ms React SDK for video calls while simplifying the complexities of live video use. The blog focuses on implementing a grayscale filter using HTML Canvas elements and WebGL, providing a step-by-step guide on creating a plugin that processes video frames to convert RGB images to grayscale through a weighted sum algorithm. It highlights the integration of this filter into a video call application, employing 100ms SDK hooks to toggle the filter on and off, and encourages experimentation with additional filters and image processing techniques. The narrative sets the stage for future discussions on AR filters, underscoring the potential for expanding the project's capabilities.
