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:
- If
MediaRecorder.state
is "inactive", raise a DOMInvalidState
error and terminate these steps. If not, continue to the next step. - Set
MediaRecorder.state
to "paused". - Stop gathering data into the current
Blob
, but keep it available so that recording can be resumed later on. - Raise a
MediaRecorder.pause
event.
Syntax
MediaRecorder.pause()
Errors
An InvalidState
error is raised if the pause()
method is called while the MediaRecorder
object’s MediaRecorder.state
is "inactive" — the media recording cannot be paused if recording is not occurring, and if it is already paused, pause()
will have no effect.
Example
... pause.onclick = function() { mediaRecorder.pause(); console.log("recording paused"); } ...
