React Whammy: A React Component for Real Time JavaScript WebM Encoder

This is a React Component for the original JS Library > Whammy.

For detail explanation, please visit original library. Essentially, this is a library to convert Canvases into a .webm using JS with easy to use API and adjustable FPS.

All the credit goes to the original creator, this library just fixed some critical bugs and convert to React Component.

Demo (Using Chrome)

Basic Usage

Install and import it into the react project

npm -i s react-whammy
import Whammy from 'react-whammy'

Initialise the Encoder

var encoder = new Whammy.Video(15)

That 15 over there is the frame rate.

Add Canvas

encoder.add(context or canvas or dataURL);

Here, you can add a frame, this happens fairly quickly because basically all it's doing is running .toDataURL() on the canvas (which isn't exactly a speed-demon either, but it's acceptable enough most of the time) and plopping the result onto an array (no computation or anything). The actual encoding only happens when you call .compile()

encoder.compile(false, (output) => {
	const video = URL.createObjectURL(output)
})

And you're done. Awesome.
