[gst-devel] Visualization with Python

[Timo]

Hello, I'm looking for a way to execute commands when music changes. 
Like visualizations in music players, but instead of changing weird 
lines on the screen, I want to do things.
Now I found out about playbin, but I can't get this to work, and can't 
find that much documentation about the subject with Python.
This is a bit that I could figure out, but can't get any further:
pipeline = gst.element_factory_make('playbin', 'playbin')
vis = gst.element_factory_make("goom")
pipeline.set_property('vis-plugin', vis)


And if this is possible, can this also be done without writing a plugin 
for a music player? But just use my own program and use the soundcard or 
something to hear the sounds? This way I don't have to write a plugin 
for a couple of players but just use my own GUI.


Thanks in advance,

Timo
