        var filepath = 'filename.mp4';
        var con_num = 4;

        let stime = new Date().getTime();
        console.log('start download, concurrency: ' + con_num);

        var downloader = new speed-down.Downloader(url, filepath, {
            'concurrency': con_num,
            'progress_throttle': 4000
        });

        downloader.onProgress((pct, tinfo, pinfo) => {
            console.log('progress:',pct);
        });

        let ret = await downloader.download();
