These are GStreamer questions, so I'd suggest first reading the GStreamer application developers manual and API documentation (the python API is similar to the C API), looking for example code, then asking on the GStreamer IRC channel or mailing list if you have further questions. I've never used the GStreamer spectrum element before, so I can't give definitive or even particularly well informed answers, but I'll have a go.. - the magnitude would be a part of the message structure, so msg.structure['magnitude'] would probably give you something (the element documentation should be useful here) - if you only want the spectrum information messages, connect to the 'message::element' signal and check that the message source is the spectrum element (msg.src == self.spectrum) - the messages are emitted as the spectrum element processes data, not as the data is actually played. There is a way to synchronize with the pipeline using the timestamp data in the messages, but I don't know the details. _______________________________________________ rhythmbox-devel mailing list rhythmbox-devel@gnome.org http://mail.gnome.org/mailman/listinfo/rhythmbox-devel
