switchOff/switchOn twilio 没有按预期工作

如何解决switchOff/switchOn twilio 没有按预期工作

我想检测 Twilio 网络带宽 API 上的关闭和开启事件。我正在关注这篇文章 (https://www.twilio.com/docs/video/tutorials/using-bandwidth-profile-api)。

这是我对 api 的配置。

  bandwidthProfile: {
          video: {
            mode: 'grid',trackSwitchOffMode: 'detected',maxSubscriptionBitrate: 2400000,// 2.4MB
            dominantSpeakerPriority: 'high',maxTracks: 3,renderDimensions: {
              high: { width: 1080,height: 720 },standard: { width: 640,height: 480 },low: { width: 160,height: 80 }
            }
          }
        },

我每次都得到 isSwitchOff 值为 false。

提前致谢

编辑这是使用 isSwitchedOff 的代码：

const [isSwitchedOff,setIsSwitchedOff] = useState(track && track.isSwitchedOff);
useEffect(() => {
  setIsSwitchedOff(track && track.isSwitchedOff)
  if (track) {
    const handleSwitchedOff = () => setIsSwitchedOff(true)
    const handleSwitchedOn = () => setIsSwitchedOff(false)
    track.on("switchedOff",handleSwitchedOff)
    track.on("switchedOn",handleSwitchedOn)
    return () => {
      track.off("switchedOff",handleSwitchedOff);
      track.off("switchedOn",handleSwitchedOn);
    };
  }},[track]);
