You have two options. First, you can change the media file in filesrc when
you are in STATE_READY rather than STATE_NULL. You only really need to go
into STATE_NULL when you are about to dismantle your pipeline (ie for
program cleanup).

If for some reason you have to put filesrc in a state that causes your sink
to perform an action you don't like, you can LOCK the state of the sink so
it ignores requests to change state. This is done with one of the
gst_element_... function calls.
