MediaRecorder: resume() method

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

If MediaRecorder.state is already "recording", calling resume() has no effect.

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 InvalidStateError exception 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.

Syntax

js
resume()

Parameters

None.

Return value

None (undefined).

Exceptions

InvalidStateError DOMException

Thrown if the MediaRecorder is currently "inactive".

Examples

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