[gst-devel] Playing Mp3 help

[Tiago Katcipis]

It would be easier if you show your on_pad_added function, and if you tell
exactly what error messages do you get when you run your application.

To investigate the capabilities of a element you can use gst-inspect.

On a terminal you can type for example:
gst-inspect flump3dec

it will give an complete specification of the flump3dec element.

best regards,
Katcipis
