Expected results

Encoding and decoding with GPU

You might want to use the h264_nvenc encoder. Would suggest you to read this: https://developer.nvidia.com/blog/nvidia-ffmpeg-transcoding-guide/

try many times, and finally

//exec('ffmpeg', ['-hwaccels'], (err, stdout, stderr) => { //❌
exec('ffmpeg -hwaccels', [''], (err, stdout, stderr) => { //✔
    if (err) {
        console.log(stderr);
    }

    console.log('\nffmpeg -hwaccels:\n---------------------\n');
    console.log(stdout);
    console.log('\n\n');

});

and then, console out:

ffmpeg -hwaccels:
