MediaRecorder.pause

The Media.pause() method (part of the MediaRecorder API) is used to pause recording of media streams.

When a MediaRecorder object’s pause()method is called, the browser queues a task that runs the below steps:

1. If MediaRecorder.state is "inactive", raise a DOM InvalidState error and terminate these steps. If not, continue to the next step.
2. Set MediaRecorder.state to "paused".
3. Stop gathering data into the current Blob, but keep it available so that recording can be resumed later on.
4. Raise a pause event.

Syntax

MediaRecorder.pause()

Return value

undefined.

Exceptions

InvalidStateError

The MediaRecorder is currently "inactive"; you can't pause recording if it's not active. If you call pause() while already paused, it silently does nothing.

Example

...

 pause.onclick = function() {
     mediaRecorder.pause();
     console.log("recording paused");
 }

...

Specifications
