A pure JavaScript implementation of ffmetadata parsing and serialization. ffmeta follows closely
the libavformat's implementation to be as consistent as possible with FFmpeg's tools.
ffmeta exports two functions, parse() and stringify().
Use parse() to parse a string containing an ffmetadata file, it will throw a SyntaxError if the
input is invalid or return an object representation of the metadata.
Use stringify() to turn an object representation of the metadata into an ffmetadata file, it may
throw a TypeError if a chapter has invalid TIMEBASE, START or END .
Node.js example.
import * as ffmeta from 'ffmeta';
import fs from 'fs';
const metadata = ffmeta.parse(fs.readFileSync('input.ffmeta', 'utf8'));
metadata.metadata.title = 'Some Title';
fs.writeFileSync('output.ffmeta', ffmeta.stringify(metadata));
