ffmpeg module saving not working after compression

August 27, 2022

I’m just trying to save an mp4 to a different mp4 (before I even start playing around with the different compression settings). What exactly is going wrong here?

const ffmpeg = require('ffmpeg');

try {
    var process = new ffmpeg('./original.mp4');
    process.then(function (video) {
        video
        .save('./new.mp4', function (error, file) {
            if (!error) {
                console.log('Video file: ' + file);
            } else {
                console.log(error)
            }
        });
    }, function (err) {
        console.log('Error: ' + err);
    });
} catch (e) {
    console.log(e.code);
    console.log(e.msg);
}

I get the following error:

Error: Command failed: ffmpeg -i ./original.mp4  ./new.mp4
/bin/sh: ffmpeg: command not found
