Couple of things you could look into:

a) we have something called splitmuxsink, which allows you to start a
new file every N seconds/minutes. It will automatically make sure that
files start with a keyframe and are playable independently. Having said
that, it depends on the sender of course, if they send key frames
frequently enough.

You could just keep creating files of ca. 10 seconds and delete 5 out
of 6 files so you only get 10 secs every minute :)

Depends what you want to do with it exactly I suppose.


b) you can check out this example:

(you can do it without a backlog too of course)

And just start/stop things with a timer then.

Cheers
