ffmpeg removes audio from video instead of add audio to the video
trying to add background audio to a video in nodejs express, but instead of adding audio to the video it removes the audio from video how to fix?
import { path as ffmpegPath } from '@ffmpeg-installer/ffmpeg';
import ffmpeg from 'fluent-ffmpeg';
import { fileURLToPath } from 'url';
import { dirname } from 'path';
import path from 'path';
ffmpeg.setFfmpegPath(ffmpegPath);
const __filename = fileURLToPath(import.meta.url);
const __dirname = dirname(__filename);
const video = path.resolve(__dirname, 'video3.mp4');
const audio = path.resolve(__dirname, 'video5.mp4');
const destination = path.resolve(__dirname, 'output.mp4');
setTimeout(() => {
ffmpeg()
.input(video)
.input(audio)
.complexFilter([
{
filter: 'amix', options: { inputs: 2, duration: 'longest' }
}
])
.on('end', async function (output) {
console.log(output, 'files have been merged and saved.')
})
.saveToFile(destination)
}, 3000);
