Maybe we should share our code on this : I implemented a snapshot
module, which is basically a video output which holds a cache of images
(50 by default) in a specified (low) resolution and chroma, and can be
accessed through a control plugin (corba for the moment).

I wanted to submit it but was waiting to cleanly finish it by
implementing a last feature: snapshot timestamping (in order to be able
to access the snapshot corresponding to a precise position). Alas, the
p_pic->date information is not available to video output modules, and I
was watching with interest the es_out-related commits in the CVS, which
should help in this area (if I understood correctly).

If you want to have a look, it is available at:
