如何使用nodejs更改/移除测试模式，并在条带中启用直播模式？

const NodeMediaServer = require('node-media-server');

const config = {
  rtmp: {
    port: 1935,
    chunk_size: 60000,
    gop_cache: true,
    ping: 30,
    ping_timeout: 60
  },
  http: {
    port: 8000,
    allow_origin: '*'
  },
  // 其他配置...
};

const nms = new NodeMediaServer(config);
nms.run();

const ffmpeg = require('fluent-ffmpeg');

// 输入流
const inputStream = 'rtmp://example.com/live/stream';

// 输出流
const outputStream = 'rtmp://localhost/live/stream_live';

ffmpeg(inputStream)
  .output(outputStream)
  .on('end', () => {
    console.log('Stream transcoded and pushed successfully');
  })
  .on('error', (err) => {
    console.error('Error during transcoding:', err);
  })
  .run();

const { RTCPeerConnection, RTCSessionDescription } = require('wrtc');

const peerConnection = new RTCPeerConnection();

peerConnection.onicecandidate = event => {
  if (event.candidate) {
    // 发送ICE候选到远程对端
  }
};

peerConnection.ondatachannel = event => {
  const dataChannel = event.channel;
  dataChannel.onmessage = event => {
    console.log('Received message:', event.data);
  };
};

// 设置远程描述并创建答案
const remoteDesc = new RTCSessionDescription(remoteSDP);
peerConnection.setRemoteDescription(remoteDesc)
  .then(() => peerConnection.createAnswer())
  .then(answer => peerConnection.setLocalDescription(answer))
  .catch(e => console.error(e));
