Use npm to install flipnote-video globally:
npm i -g flipnote-video --saveflipnote-video -i flipnote.ppm -o -c:v libx264 -c:a aac -pix_fmt yuv420p video.mp4flipnote-video -i flipnote.ppm --metaUse npm to add flipnote-video into your project:
npm i flipnote-video --saveconst fs = require('fs');
const { parseFlipnote, FlipnoteConverter } = require('flipnote-video');
async function convert(inpath, outpath) {
// read input file
const file = fs.readFileSync(inpath);
// parse file as flipnote
const flipnote = await parseFlipnote(file.buffer);
// FlipnoteConverter extends node-fluent-ffmpeg's command object
// https://github.com/fluent-ffmpeg/node-fluent-ffmpeg
const converter = new FlipnoteConverter(flipnote);
// Web-friendly MP4 codec settings
converter.outputOptions([
'-c:v libx264',
'-c:a aac',
'-pix_fmt yuv420p',
]);
converter.output(outpath);
converter.run();
}
convert('./flipnote.ppm', './video.mp4');
