Example of NodeJS script to resize videos (to 1080P and 720P) using fluent-ffmpeg

ffmpeg-resize.js

(function () {
	
	var ffmpeg = require('fluent-ffmpeg');
	function baseName(str) {
		var base = new String(str).substring(str.lastIndexOf('/') + 1); 
		if(base.lastIndexOf(".") != -1) {
			base = base.substring(0, base.lastIndexOf("."));
		}     
		return base;
	}

    var args = process.argv.slice(2);
    args.forEach(function (val, index, array) {
        var filename = val;
        var basename = baseName(filename);
        console.log(index + ': Input File ... ' + filename);
        
        ffmpeg(filename)
            // Generate 720P video
            .output(basename + '-1280x720.mp4')
            .videoCodec('libx264')  
            .noAudio()
            .size('1280x720')
		  
		    // Generate 1080P video
		    .output(basename + '-1920x1080.mp4')
		    .videoCodec('libx264')
		    .noAudio()
		    .size('1920x1080')

            .on('error', function(err) {
                console.log('An error occurred: ' + err.message);
                
            })	
            .on('progress', function(progress) { 
                console.log('... frames: ' + progress.frames);
                
            })
            .on('end', function() { 
                console.log('Finished processing'); 
                
            })
            .run();
        
    });	
    
})();

Hello, could you give me an example of how to use this code.

@augustocesar84 This is very old code and I no longer work on anything close to this, but this is already an example, and from the code, I would guess you just call it with

node ffmpeg-resize.js myvideo.mp4

But you will need to setup node with a package.json that includes the fluent-ffmpeg package, but who knows how much they have changed since 2015. You should check the project: https://github.com/fluent-ffmpeg/node-fluent-ffmpeg

@augustocesar84
Note also I did create a docker image at the time (https://github.com/dkarchmer/docker-fluent-ffmpeg), so if you use docker, it should just be

docker pull dkarchmervue/fluent-ffmpeg
docker run --rm -ti -v ${PWD}:/work dkarchmervue/fluent-ffmpeg node ffmpeg-resize.js myvideo.mp4

But as I said, that was a long time ago, so it may or may not work. You are on your own here if does not.

this code hasn't worked on the synchronization
