------- Comment #18 from Stefan Kost (gstreamer, gtkdoc dev)  2008-08-19 19:57 UTC -------
In answer to comment #12. Thats not the problem here.

      FX1
- T <     >  A -
      FX2

Problem is that when T -> FX1 is negotiated, it negotiates FX1 -> A, then A ->
FX2  and FX2 -> T and then it locks.

We could explot some facts:
* tee and adder need to have the same format for all request pads
* if we have queried t.src to negotiate t.sink1 we can use the same to t.sink2
if t.src has not changed

What does the patch change:
* it caches caps to avoid calling _getcaps()
* it does not merge caps for all request pads as they must be the same anyway
