recording suspend/resume

[mattes]

I am looking for a way to pause and resume an active live recording?
While in pause/suspend mode the frames should be discarded.
Is there a way of achieving that with gstreamer?

Possibly a gstreamer plugin or so. Maybe something I could add 
to my pipeline and control whenever I want to suspend the recording
and resume again.

The idea is, instead of dealing with multiple video snippet (aka. playlist),
to have one continuous media file.

Any pointers are appreciated?
