MediaRecorder.resume()

The MediaRecorder.resume() method (part of the MediaRecorder 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:

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

Syntax

MediaRecorder.resume()

Errors

An InvalidState error is raised if the resume() method is called while the MediaRecorder object’s MediaRecorder.state is "inactive" — the recording cannot be resumed if it is not already paused; if MediaRecorder.state is already "recording", resume() has no effect.

Example

...

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