I created a webcodecs-compatible package for Node.js that you might find useful

Repo: https://github.com/Brooooooklyn/webcodecs-node

This package has zero system package dependencies, meaning you don't need to run apt/brew install xxx before using it. Additionally, this package is compatible with GLIBC 2.17, so you won't have to worry about encountering issues with GLIBC xxx not being found on any GNU systems.
