I respond to myself but it could help anyone else. Now it works.
I modified the about-to-finish event, setting the pipeline to ready, once
the uri was set, I change the pipeline state to PLAY again
void about_to_finish_cb (GstElement * element, gpointer * uri)
gst_element_set_state (play, GST_STATE_READY);
gchar* uri2 = (gchar*)uri;
g_object_set (G_OBJECT (element), "uri",uri2, NULL);
gst_element_set_state (play, GST_STATE_PLAYING);
Any suggestion are welcome, I don't know if I am doing the right thing.
According to some examples change the pipeline state it woudln't necessary,
but it didn't work for me.
