The docs say somewhere that the probe callback has the same signature as
a handler for the have-data signal of GstPad, so the function you pass
to add_buffer_probe looks like:

static gboolean
my_probe (GstPad *pad, GstMiniObject *obj, gpointer user_data)
{
   GstBuffer *buffer = GST_BUFFER (obj);
...
