Freezing the output of as src element

[Eric Trousset]

Hi
I am currently writing a source element that needs to output a buffer only when a event is triggered, but for now the create function is called in loop, and if I wait for my event in it, my application's run loop is blocked to.

I tried to figure out how the imagefreeze plugin works but couldn't manage to understand how the pas task is working.

Can someone give me some hints on how to make the create function blocking until I get an event (I have a wait function for this event).

Cheers,
Eric
