JavaScript Not show the time/seconds until 'record' starts on html5 player

[chrisj]

This code allows the page vistor to click a 'display' button to show the camera view on the page, but not start the video recording (they can select a seperate 'record' button to start recording). However, the timer/seconds start upon selecting 'display' the camera view. I'd like help with having the time/seconds not start until 'record' button is clicked. Any help/guidance is appreciated. Here's the code:

let blobs = [];
let stream, mediaRecorder, blob;

let video = document.getElementById("video");
var displaying = false;
var recording = false;
async function display() {
  stream = await navigator.mediaDevices.getUserMedia({
    audio: true,
    video: true,
  });
  video.srcObject = stream;
  displaying = true;
}
function startRecording() {
  if(displaying){
    mediaRecorder = new MediaRecorder(stream);
    mediaRecorder.ondataavailable = (event) => {
    // Let's append blobs for now, we could also upload them to the network.
      if (event.data) {
        blobs.push(event.data);
      }
    };
    mediaRecorder.onstop = doPreview;
    // Let's receive 1 second blobs
    mediaRecorder.start(1000);
    recording = true;
  }
}

function endRecording() {
  if(recording){
    // Let's stop capture and recording
    mediaRecorder.stop();
    stream.getTracks().forEach((track) => track.stop());
    recording = false;
  }
}

function doPreview() {
  if (!blobs.length) {
    return;
  }
  // Let's concatenate blobs to preview the recorded content
  blob = new Blob(blobs, { type: mediaRecorder.mimeType });
  video.srcObject = null;
  video.src = URL.createObjectURL(
    blob,
  );
}

@chrisj I do not see anything to call any function nor do I see any code or function the starts a timer. So I asume that the timer is a function of the display and has nothing to do with your JS. Take a look at the documents for the video player.

Thank you. I found a solution
