The MediaRecorder.resume()
method (part of the MediaRecorder API) is used to resume media recording when it has been previously paused.
When the resume()
method is invoked, the browser queues a task that runs the following steps:
- If
MediaRecorder.state
is "inactive", raise a DOMInvalidState
error and terminate these steps. IfMediaRecorder.state
is not "inactive", continue to the next step. - Set
MediaRecorder.state
to "recording". - Continue gathering data into the current
Blob
. - Raise a
resume
event.
Syntax
MediaRecorder.resume()
Errors
An InvalidState
error is raised if the resume()
method is called while the MediaRecorder
object’s MediaRecorder.state
is "inactive" — the recording cannot be resumed if it is not already paused; if MediaRecorder.state
is already "recording", resume()
has no effect.
Example
... pause.onclick = function() { if(MediaRecorder.state === "recording") { mediaRecorder.pause(); // recording paused } else if(MediaRecorder.state === "paused") { mediaRecorder.resume(); // resume recording } } ...
