MediaRecorder: resume() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.

See full compatibility

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:

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.
Set MediaRecorder.state to "recording".
Continue gathering data into the current Blob.
Raise a resume event.

Syntax

resume()

Parameters

None.

Return value

None (undefined).

Exceptions

InvalidStateError DOMException: Thrown if the MediaRecorder is currently "inactive".

Examples

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