store audio/video into circular buffer

[Damiano Pinarello]

Hi,

I read in a forum that queue can work with live-sources, while queue2 can't (right now).
But I consider this information old, beacuse the message is dated to 09/2010.
Do you have some newest information about it?

To better explain my need, I'm working on a IP camera base on dm365 that used
gstreamer. The pourpose is this: when an interrupt arrives (for example due to
motion detection) I must have a 30 seconds video before it to undestand what
have generated the interrupt.

I think to do this with a sort of circular buffer before sink element.
This new element will continue to store data, and when an interrupt arrives
it must reorder the buffer and put the content into a file.
After that start to normally send video to sink element.

Thanks,
Damiano
