Is there any way to upload fluent-ffmpeg converted videos directly to s3 without storing them on local?

Question

Is it possible to store ffmpeg output directly to s3 without downloading it in local or any other storage? Below is my understanding of ffmpeg which converts format of video. I have done conversion part but i need to store it's output directly to s3 bucket so anyone have idea regarding this problem ?

const AWS = require('aws-sdk');
const fs = require('fs');
const ffmpeg = require('fluent-ffmpeg');
const axios = require('axios');


const s3 = new AWS.S3({
    endpoint: 's3-ap-south-1.amazonaws.com',   // Put you region
    accessKeyId: S3_ACCESS_KEY_ID,       // Put you accessKeyId
    secretAccessKey: S3_ACCESS_SECRET_KEY,   // Put you accessKeyId
    Bucket: S3_BUCKET_NAME,         // Put your bucket name
    signatureVersion: 'v4',
    region: 'ap-south-1'           // Put you region
});

var params = {
    Bucket: S3_BUCKET_NAME,
    Delimiter: '',
    Prefix: S3_STORE_PATH
};
s3.listObjects(params, function (err, data) {
    if (err) throw err;
    console.log(data);
    data.Contents.forEach(function (obj, index) {
        const file_name = obj.Key;
        const type = "mp4";
        console.log(obj.Key)
        const url = s3.getSignedUrl('getObject', {
            Bucket: S3_BUCKET_NAME,
            Key: obj.Key,
            Expires: signedUrlExpireSeconds
        });
        console.log("SIGNED URL= ", url);
        const filename = file_name.split('.').slice(0, -1).join('.');
        const localFileOutput = `${filename}.${type}`;
        // const localFileOutput = `${bucket_url}${filename}.${type}`;
        console.log(localFileOutput);
        const key = `${filename}.${type}`;
        const convert_video = async (req,res) => {
            await new Promise((resolve, reject) => {
                ffmpeg().input(url)
                    .toFormat('mp4')
                    .output(localFileOutput)
                    .on('end', async () => {
                        const params = {
                            Bucket: S3_BUCKET_NAME,
                            Key: key,
                            Body: localFileOutput
                        }
                        // const fileContent = await fs.readFileSync(localFileOutput);
                        await s3.putObject(params).promise();
                        resolve();
                    }).run();
            });

            // res.send("success")
        }
        convert_video();
    });
});
