Typically, you get such errors when disposing (freeing) your pipeline when it's not in NULL state yet, just as the error says - ie., you need to give GStreamer a chance to go through the state-changes to reach NULL before disposing your pipeline and its elements. One way to do that is to use (the Python equivalent of) a blocking gst_element_get_state after you set the state. Cheers, Dirk. -- Dirk-Jan C.
