MediaRecorder.stop()

The MediaRecorder.stop() method (part of the MediaRecorder API) is used to stop media capture.

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

If MediaRecorder.state is "inactive", raise a DOM InvalidState error and terminate these steps. If the MediaRecorder.state is not "inactive", continue on to the next step.
Set the MediaRecorder.state to "inactive" and stop capturing media.
Raise a dataavailable event containing the Blob of data that has been gathered.
Raise a stop event.

Syntax

 MediaRecorder.stop()

Errors

An InvalidState error is raised if the stop() method is called while the MediaRecorder object’s MediaRecorder.state is "inactive" — it makes no sense to stop media capture if it is already stopped.

Example

...

  stop.onclick = function() {
    mediaRecorder.stop();
    console.log("recorder stopped, data available");
  }
