WebCodecs
/wɛb ˈkoʊ.dɛks/ · Noun · Development
Definitions
A low-level browser API that provides direct access to hardware video and audio encoders and decoders, allowing frame-by-frame control over media processing without the overhead of the MediaSource Extensions or HTMLMediaElement pipeline — used for video editing, game streaming, and real-time communication.
In plain English: A browser feature that gives web apps direct access to video encoding and decoding hardware for advanced media processing.
Example: "We use WebCodecs to decode individual H.264 frames for the video editor's timeline scrubbing — it's way faster than hacking it through a hidden <video> element."
