I have also experienced more warnings, but I don't know what's the best way to 
solve it because they are related to gstreamer and I'm not familiar with it. I 
attach them in case anyone can solve them or help me showing the best way to 
solve do it.

Looking to the code, the problem seems to be in this macro:
GST_BOILERPLATE

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-
GstUtils.html#GST-BOILERPLATE:CAPS

As I said I don't have previous experience with gstreamer and I don't know if 
it is a good idea to declare the "get_type" function previously.
