[gst-devel] Visualization with Python

[Timo]

Hey Eric,
Thanks for your answer, but I know near to nothing about C, so it's a 
bit hard for me.

I think I didn't make myself that clear. I don't want to know when the 
music stops or changes song. But the actual changes in the music (pitch, 
frequency, etc.), just like a visualizer. But instead of changing colors 
according to the music, I want to execute commands according to the music.
And all of this in Python.

Thanks,

Timo
