ffmpeg.wasm brings FFmpeg, one of the most widely used tools for converting and processing video and audio files, directly into a web browser. Normally, FFmpeg is a command-line program you install on your computer. This project ports it to WebAssembly (a format that lets compiled code from other languages run in a browser at near-native speed), which means you can record, convert, and stream video and audio entirely in the browser without sending files to a server. This opens up possibilities like in-browser video editors, format converters, or audio tools that work completely client-side. The project is written in C and JavaScript, marked as experimental, and licensed under MIT. The README does not provide further detail about supported formats, browser compatibility requirements, or usage examples beyond what is described above.
