Usually for me if a pipeline doesn't move into the proper state it means
one of its elements is having troubles moving into that state. Usually
I'll use GST_DEBUG=X as well as whatever the environment variables are
to have it output dot files so that I can visually look at the state of
the elements in the pipeline. Usually what will happen is that all but
one will be in the state I want and then using gst_debug I find the
message that one element is providing as to why it isn't working... just
my 2 cents on how to find the answer to your question.
