How to do lengthy processing in an element

[philippe renon]

Hi,
I have an element that needs, at some point in time after analyzing a number of frames, to do a lengthy processing. Currently it is done in the chain() method, stalling the pipeline, but could be done asynchronously.
Does gstreamer have facilities for launching some task in a separate thread and make the result available to the element once done, all this without having to muck with threads, locks, etc... ?

Cheers,Philippe.
