MediaRecorder: resume() method

The MediaRecorder.resume() method (part of the MediaStream Recording API) is used to resume media recording when it has been previously paused.

When the resume() method is invoked, the browser queues a task that runs the following steps:

1. If MediaRecorder.state is "inactive", raise a DOM InvalidState error and terminate these steps. If MediaRecorder.state is not "inactive", continue to the next step.
2. Set MediaRecorder.state to "recording".
3. Continue gathering data into the current Blob.
4. Raise a resume event.

resume()

pause.onclick = () => {
  if (MediaRecorder.state === "recording") {
    mediaRecorder.pause();
    // recording paused
  } else if (MediaRecorder.state === "paused") {
    mediaRecorder.resume();
    // resume recording
  }
};
