我正在研究 WebRTC 并在不同的浏览器页面上连接两个对等点，一个作为发起者的对等点带有这个 url http://localhost:4200/#init，另一个是视频接收器带有这个 url http://localhost:4200/。建立成功连接后，第一个对等方与另一个对等方共享其视频，但我面临的问题是其他对等方没有播放或接收视频。

export class SimpPeerComponent implements OnInit {

  targetpeer: any;
  peer: any;
  stream: MediaStream

  async ngOnInit() {
    try {
      // This peer is the initiator and transfering the streaming to the other connected peer 
      if (location.hash === '#init') {
        let stream = await navigator.mediaDevices.getUserMedia({ video: true })
        this.peer = new SimplePeer({
          initiator: location.hash === '#init',
          stream: stream
        })
      }
      else {
        this.peer = new SimplePeer()
      }

      // triggers when signal is sent from remote
      this.peer.on('signal', function (data) {
        console.log(JSON.stringify(data));
      })

      this.peer.on('data', (data) => {
        console.log('Received Data: ' + data)
      })

      this.peer.on('stream', (stream) => {
        // got remote video stream, now let's show it in a video tag
        this.videoElement.srcObject = stream
      })
    } catch (error) {
      console.log(error)
    }
  }

  connect() {
    this.peer.signal(this.targetpeer);
  }

  message() {
    this.peer.send('Hello world');
  }

  @ViewChild('myvideo') videoElementRef: ElementRef;
  get videoElement(): HTMLVideoElement {
    return this.videoElementRef.nativeElement
  }
}

<div class="row">
    <div class="col d-flex justify-content-center">
        <video #myvideo autoplay controls class="video mb-2"></video>
    </div>
</div>

<div class="row">
    <div class="col d-flex justify-content-center">
        <input type="text" class="form-control-sm mr-1" [(ngModel)]="targetpeer">
        <button class="btn btn-success" (click)="connect()">Connect</button>
        <button class="btn btn-primary" (click)="message()">Send</button>
    </div>
</div>

可能是什么问题？请指导！！！

我犯的一个简单的愚蠢错误是，现在只有chrome浏览器支持它，但我一直在运行它Opera并花了我一整天的时间来解决这个错误：D
