git submodule init
git submodule update
Usage
var jsivf = require('../src/jsivf.js');
var ivf = new jsivf();
//Get some binary data
//Parse the header
ivf.receiveBuffer(data);
ivf.parseHeader();
//Dump each output frame
while(ivf.currentFrame < ivf.frameCount){
var frameBuffer = ivf.processFrame();
var filename = 'frame_' + ivf.currentFrame + '.bin';
fs.writeFileSync(dir + '/' + filename, frameBuffer);
}
Tests
npm run-script test
Will read the first test vector and dump contents to tmp directory
npm run-script clean
Removes test frames
