Is there a way to hide the command prompt?

[Agusacco]

I wanted to know if there was any way to hide the command prompt while converting, because that piece of code runs repeatedly, and it's annoying that the command prompt appears while I'm doing something else.

• fluent-ffmpeg version: 2.1.2
• OS: Windows 10

                ffmpegCommand = ffmpeg();
                var outStream = fs.createWriteStream("audio.mp3");

                await new Promise((resolve, reject) => {

                    ffmpegCommand
                    .setFfmpegPath("C:\\ffmpeg\\bin\\ffmpeg.exe")
                    .format('mp3')
                    .input(stream)
                    .seekInput(arrayEntradas[4][indexEntrada])

                    .output(outStream, { end:true })

                    .on('error', function(err, stdout, stderr) {
                        console.log('Cannot process video: ' + err.message);
                        reject(err);
                    })

                    .on('end', function(stdout, stderr) {
                        console.log('Transcoding succeeded!');
                        resolve();
                    })

                    .on('start', function(commandLine) {
                        console.log('Spawned Ffmpeg with command: ' + commandLine);
                    });

                    if (arrayEntradas[3][indexEntrada] == "1"){

                        ffmpegCommand
                        .audioFilters("bass=g=10", "crystalizer=i=3", "acrusher=.1:1:64:0:log")
                        .duration(5);

                    }

                    else {

                        ffmpegCommand
                        .duration(15)

                    }

                    ffmpegCommand.run();

                });

I found a solution. It is a change in the processor.js script. It can be implemented, but my problem only occurs if you are using PM2!
