var mp4 = require('mp4-stream') var fs = require('fs') var decode = mp4.decode() fs.createReadStream('video.mp4') .pipe(decode) .on('atom', function (atom) { console.log('found atom (' + atom.type + ') at ' + atom.offset + ' (' + atom.length + ')') if (atom.container) { console.log('atom has child atoms (will be emitted next)') } if (atom.stream) { console.log('atom has stream data (consume stream to continue)') atom.stream.resume() } })All atoms have a type thats a 4 char string with a type name.
