[LAD] python, gtk, gstreamer

Ignorant here. Trying to scrounge around and make something work for a demo purpose. In python I am trying to build this pipeline: pipeline_txt = ( 'jackaudiosrc ! ' 'level name=level interval=1000000000 !' 'jackaudiosink') pipeline = gst.parse_launch(pipeline_txt) I have been trying that a number of ways. So, I basically watch the bus for level info. In a subroutine, I can print the peak info to the terminal. I can't seem to figure out how to pass this info back to the rest of the program so that I can hook it up to a graphical meter. Cna anyone point me to some simple code doing something like this? Give me some clues that might help someone who seems to be being very dense for days now? all the best, drew
