WebCodecs API

Get direct, low-level access to the browser's built-in media codecs: encode and decode audio and video with hardware acceleration for maximum performance.

The WebCodecs API delivers critical performance gains by exposing the browser's native, often hardware-accelerated, media codecs. This is a direct solution for developers needing fine-grained control over media processing: you can now work with individual `VideoFrame` objects and encoded audio/video chunks without relying on inefficient WebAssembly polyfills. It provides dedicated interfaces—like `VideoEncoder` and `AudioDecoder`—to manage encoding and decoding queues asynchronously. This low-latency capability is essential for demanding applications: specifically, real-time video conferencing, professional video editors, and high-fidelity game streaming.
