## Description

ffmpeg.wasm is a browser-based multimedia processing engine that brings the capabilities of the FFmpeg library directly to the client environment. By utilizing WebAssembly, it enables audio and video transcoding, format conversion, and stream recording to occur entirely within the browser without requiring server-side infrastructure.

The library distinguishes itself by executing resource-intensive media tasks in background threads, ensuring that the main user interface remains responsive during complex operations. It manages data through an isolated, in-memory virtual file system, allowing for efficient input and output handling without the need for direct disk access.

This tool provides a comprehensive suite for local media manipulation, including real-time processing and the application of visual filters. It is distributed as a library that integrates into web applications to facilitate high-performance multimedia tasks locally.
