MediaRecorder: stop() 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.

The stop() method of the MediaRecorder interface 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.
