我已经在 Ionic 平台上实现了视频通话集成，我可以打电话，但我不能静音音频和视频流。为了获取本地流，我使用了 apiRTC.getLocalStreams()，但获取 getLocalStreams 不是一种方法。对于静音音频，我使用了 localStraem.muteAudio()、this.webRTCClient.toggleAudioMute(this.callId)。这里也同样的错误静音音频不是一种方法。有人可以帮我解决这个问题吗？

谢谢你。

这是我的代码

首先，我会确保声明的“apiRTC”变量不是未定义的，并且您知道如何导入它以使其定义。

然后，确保首先执行 apiRTC 的 init 方法 - 将此代码块移动到您声明 apiRTC var 的位置：

declare var apiRTC;

apiRTC.init({
      onReady: this.sessionReadyHandler,
      apiKey: "My APIKey",
});

注意：目前在您的代码中，您尝试在初始化之前使用 apiRTC。

然后，我会将您的方法 sessionReadyHandler 拆分，因为您实际上是在初始化 this.localStream （straem？）。

代码将是这样的，里面有我的评论：

declare var iosrtc;
declare var apiRTC;

apiRTC.init({
    onReady: this.sessionReadyHandler,
    apiKey: "My APIKey",
});

console.log(apiRTC) // should return defined here

declare var apiCC;

const STATE_WAIT = "wait";
const STATE_INCALL = "incall";

const LABEL_CALL = "Call";
const LABEL_HANGOUT = "Hangout";

const COLOR_CALL = "#5cb85c";
const COLOR_HANGOUT = "#d9534f";

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
}) // get rid of ; here
export class HomePage {

  distantNumber; // no point using type 'any' here
  webRTCClient;
  infoLabel;
  buttonLabel;
  buttonColor;
  state;
  localStraem;
  callId;
  isMute;

  constructor(public navCtrl: NavController, public alertCtrl: AlertController, public platform: Platform, public nativeAudio: NativeAudio) {

    // initialize handlers inside ngOnInit hook and you do not need binding 'this' here:
    /* this.incomingCallHandler = this.incomingCallHandler.bind(this);
    this.userMediaErrorHandler = this.userMediaErrorHandler.bind(this);
    this.remoteStreamAddedHandler = this.remoteStreamAddedHandler.bind(this);
    this.hangupHandler = this.hangupHandler.bind(this);
    this.refreshVideoView = this.refreshVideoView.bind(this);
    this.sessionReadyHandler = this.sessionReadyHandler.bind(this);
    this.userMediaSuccessHandler = this.userMediaSuccessHandler.bind(this); */

  };

  ngOnInit() {

    this.nativeAudio.preloadComplex('uniqueI1', 'assets/tone.mp3', 1, 1, 0).then((succ) => {

    setTimeout(this.refreshVideoView, 1000);
  }

  initMediaElementState(callId) {
    this.webRTCClient.removeElementFromDiv('mini', 'miniElt-' + callId);
    this.webRTCClient.removeElementFromDiv('remote', 'remoteElt-' + callId);
  }
}

也不确定为什么你试图在构造函数中使用“bind(this)”。在构造函数中，“this”没有值。它是新对象（在您的情况下为 Homepage 类）的替代品。'this' 的值将在创建新对象时成为新对象。

Got an answer for mute options, here the code just replace userMediaSuccessHandler with following userMediaSuccessHandler method in above code

userMediaSuccessHandler(e) {
    console.log("userMediaSuccessHandler", e);
    this.webRTCClient.addStreamInDiv(
      e.detail.stream,
      e.detail.callType,
      "mini",
      'miniElt-' + e.detail.callId,
      { width: "128px", height: "96px" },
      true
    );

    this.myStreemAudio = e.detail.stream;

  }

  myStreemAudio;
  isMute = false;
  muteCall(val) {

  if (val == 0) {
      this.myStreemAudio.getAudioTracks()[0].enabled = false;
    } else {
      this.myStreemAudio.getAudioTracks()[0].enabled = true;
    }

    console.log('de.........' + val)
  }


  muteVideo(val) {
    if (val == 0) {
      this.myStreemAudio.getVideoTracks()[0].enabled = false;
    } else {
      this.myStreemAudio.getVideoTracks()[0].enabled = true;
    }
  }
