Pipe multiple JPG's into an animated GIF using Node JS

I am trying to pipe 5 specific JPG file names into an animated GIF. I have looked through several libraries and found Gif-Encoder. I am not very good with streams. I cannot seem to figure out how to pipe the RGB result from the JPEG Decoder into the addFrame() method of the encoder.

function createAnimatedGif(jpgPaths, animatedGifPath) {
    let encoder = new GifEncoder(1280, 720);

    let writeStream = fs.createWriteStream(animatedGifPath);
    encoder.pipe(writeStream);
    encoder.writeHeader();

    jpgPaths.forEach(filePath => {
        fs.createReadStream(filePath)
            .pipe(new JPEGDecoder)
            //.pipe(encoder);
            //.pipe(pixels => encoder.addFrame(pixels));
    });

    encoder.finish();
}
