MediaRecorder: stop() method

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

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

  1. 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.
  2. Set the MediaRecorder.state to "inactive" and stop capturing media.
  3. Raise a dataavailable event containing the Blob of data that has been gathered.
  4. Raise a stop event.

Syntax

js

stop()

Parameters

None.

Return value

None (undefined).

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.

Examples

js

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