Hi, Rhythmbox uses a Gstreamer pipeline to render and manipulate audio. This pipeline is a chain of elements each having its own purpose. You should learn at least the basics about Gstreamer, but the RBPlayerGstFilter class exposes the relevant part of inserting an element like a spectrum analyser into the playback pipeline.
Some times ago I did a spectrum analyzer plugin and a patch is attached to this bug: http://bugzilla.gnome.org/show_bug.cgi?id=327367 I don't know if it still compiles with current rhythmbox, but it might be a good starting point. cheers, Christophe On Sun, Apr 26, 2009 at 10:50 AM, Seemanta Dutta <seema...@gmail.com> wrote: > Hi, > I am planning to write a spectrum analyzer plugin for rhythmbox.
