The main difference is that gst_pad_get_parent() will return a reference
on the object (you need to unref it when done). This prevent another
thread from freeing the object while you are doing your operations.
GST_PAD_PARENT() is normally used when the stream lock is taken, i.e.
when the chain function is called.
