Thank you. I've read this already, and cited in my original message. 
I will be happy to understand the underlying technologies as quickly as
possible, but, unfortunately, my information sources are poor. All action
signals of the camerabin have void return type and don't return any values.

The docs to the g_signal_emit () function say that its "..." parameter is
the list of "parameters to be passed to the signal, followed by a location
for the return value. If the return type of the signal is G_TYPE_NONE, the
return value location can be omitted."

Does it mean that I should call, for example, 
  GstTagList *taglist;
  g_signal_emit_by_name(m_player, "get-audio-tags", &taglist);

?
