After adding some debug output to videomixer, this happens:

changing z-order (sink_1): 0 -> 0
changing z-order (sink_0): 10000 -> 10000
EOS (sink_0)
EOS (sink_1)
requesting (sink_2)
changing z-order (sink_0): 10000 -> 10000
changing z-order (sink_1): 0 -> 0
changing z-order (sink_2): 2 -> 9999
EOS (sink_0)
EOS (sink_2)
EOS (sink_1)
releasing (sink_0)
changing z-order (sink_2): 9999 -> 9999
changing z-order (sink_1): 0 -> 0
EOS (sink_2)
EOS (sink_1)


The black frame happens about the time where sink_2 is requested. Why are there
3 sinkpads used by pitivi?
