gst_element_set_state deadlock

[Kocsis Tibor]

Hi,

I want to destroy a branch in a pipeline, keeping the pipeline in
PLAYING. I have two sources, two sinks, they are in the same pipeline
and they don't have any joint element. If i set the state one of the
branchs's elements to null, in the 50% of the cases i have a deadlock
at the gst_element_set_state. Can somebody explain me what is the
correct order to destroy dynamically a branch in a pipeline? I sending
flushstart/flushstop/eos events, set the elements to NULL from the
source to the sink and in reversed order, but nothing works in all
case...

Thanks in advance,
Tibor
