I am creating an app where user can record and play there video. I am doing it in same video tag to stream and play the recorded video but I am having issue when I start the recording thrid time. For th first time when I start record and stop then play the video its works fine and when do again it works fine but when so it one more time the media stream stop and I get error DOMException: Failed to execute 'start' on 'MediaRecorder': There was an error starting the MediaRecorder. I am not able to understand why its not working on third time. Please if someone can help me out finding the issue. This is my code. Start Camera

startCamera(): void {
   
    this.videoElement.play();
    navigator.mediaDevices
      .getUserMedia({
        video: true,
        audio: {
          echoCancellation: {exact: true}
        },
      })
      .then((stream) => {
        this.videoStream = stream;
        this.addStream();
      })
      .catch((err) => {
      });
  }

Adding Stream to video tag

private addStream(): void {
    this.videoElement.srcObject = this.videoStream;
  }

Start Record record(): void {

    if (this.videoElement.srcObject === null) {
      this.videoElement.removeAttribute('src')
      this.addStream();
      this.videoElement.play();
    }
    const sUsrAg = navigator.userAgent;
    if (sUsrAg.indexOf('Firefox') > -1) {
      this.videoElement.mozCaptureStream();
      this.startRecordingMedia(this.videoElement.mozCaptureStream());
    } else { 
      this.startRecordingMedia(this.videoElement.captureStream());
    }
  }
private startRecordingMedia(stream: MediaStream): void {
    try {
      this.recorder = new MediaRecorder(stream);
      const data = [];
      this.recorder.ondataavailable = (event) => data.push(event.data);
      this.recorder.onerror = (event) => {
        console.log(event);
      };
      this.recorder.start();
      this.recorder.addEventListener('stop', () => {
        console.log('stopped')
      });
 
    } catch (e) {
      console.log(e)
     
    }
  }

Stop Recording

this.videoElement.pause();
    this.recorder.stop();
    this.videoElement.srcObject = null;
    const recordedBlob = new Blob(data);
    this.videoElement.src = URL.createObjectURL(recordedBlob);
