           Summary: Separate threadsafe queuing functionnality in a separate
                    object
           Product: GStreamer
           Version: HEAD CVS

It is currently painful to integrate threadsafe queuing functionnality in
elements since that functionality is in an element (GstQueue). That
functionnality would be needed to make a multiple input/output queue, make more
efficient demuxers, etc...

I separated the threadsafe queuing functionnality in a new GObject :
GstSafeQueue. This object has :
 _threadsafe functions, which removes any explicit locking from elements using
it,
 _handles size behaviours in time/buffers/bytes,
 _release functions to unlock push/pop functions
 _flushing mode to make push/pop functions return immediatly
 _signals informing when the queue is full/empty/running 

I also included a patched version of GstQueue which uses that new object. It's
smaller and doesn't have to worry about locking issues.

I've been using it for the past week with succes. I welcome anybody to try it
and comment on it.
