Parses MediaInfo output with Javascript!

Usage

Quickstart

  1. You can directly process a file path

    import {exec as mediainfoExec} from 'mediainfo-parser';

const mediapath = '~/Downloads/big_buck_bunny_1080p_h264.mov';
mediainfoExec(mediapath, (err, obj) => {
  console.log(obj);
})

  2. You can also manually parse output (currently, only XML is supported)

    import {exec} from 'child_process';
import {parse as mediainfoParse} from 'mediainfo-parser';

const mediapath = '~/Downloads/big_buck_bunny_1080p_h264.mov';
exec(`mediainfo --Full --Output=XML "${mediapath}"`, (stderr, stdout) => {
  mediainfoParser(stdout, (err, obj) => {
    console.log(obj);
  });
})
