Generate Thumbnail from video using Node.js

thumbnail-generator.js

"use strict";

const
    ffmpegPath = require("@ffmpeg-installer/ffmpeg").path,
    ffprobePath = require("@ffprobe-installer/ffprobe").path,
    ffmpeg = require("fluent-ffmpeg");

ffmpeg.setFfprobePath(ffprobePath);
ffmpeg.setFfmpegPath(ffmpegPath);

async function generateThumbnail(videoPath) {
    return ffmpeg(videoPath)
        .thumbnail({
            timestamps: ['50%'],
            filename: 'thumbnail.png',
            size: '320x240',
        });
}

generateThumbnail('sample-video.mp4')
    .then(() => console.log('Thumnail generated successfully'))
    .catch((err) => console.error(err));

can we use base64 in place of mp4 file

thanks
