Node.js Node js实时流媒体rtsp摄像机

我正在尝试从node js流式传输rtsp。在我的本地应用程序中，一切正常，但如果 我在AWS EC2（Linux/UNIX）上部署了相同的代码，但没有流式处理。我附加了代码片段，它只打印console.log（“1”）和console.log（“2”）。之后，它不会对任何本应控制进度的内容进行控制

const ffmpeg = require('fluent-ffmpeg');
const ffmpegInstaller = require('@ffmpeg-installer/ffmpeg');

let streamCamera = () => {
    try {
            console.log("1");
            ffmpeg.setFfmpegPath(ffmpegInstaller.path);
            console.log("2")
            var headersSent = false;
            ffmpeg('rtsp://<username>:<password>@<IP>', { timeout: 432000 }).addOptions([
                '-profile:v baseline',
                '-fflags -nobuffer', // no idea whether this causes lower latency
                '-probesize 32', // no idea whether this causes lower latency
                '-s 320x240', // resolution (scale) 640x480 480x360 320x240
                '-level 3.0',
                '-start_number 0',
                '-hls_time 1', // length of each segment (2s in this case)
                '-hls_list_size 0',
                '-hls_flags delete_segments',
                '-f hls' // format to hls
            ])
            .output('videos/output.m3u8') // output.m3u8 will be in a directory called "videos"
            .on('end', () => {
                console.log('end');
            })
            .on('progress', function(progress) {
                fs.access("videos/output.m3u8", fs.constants.F_OK, function(err) {
                    console.log("success")
                    if (err) {
                        console.log("Processing error", err)
                    } else {
                        if (headersSent === false) {
                            console.log("Processing success")
                            headersSent = true;
                            console.log("52");

                        }
                    }
                });
            })
            .run();
           
    } catch (e) {
        console.log("Error in streamCamera")
    }

}

Output:
