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.MediaRecorder.state to "inactive" and stop capturing media.dataavailable event containing the Blob of data that has been gathered.stop event.stop()None.
None (undefined).
InvalidStateError DOMExceptionThrown if the MediaRecorder is currently "inactive"; you cannot stop the recording if the MediaRecorder is not active.
