You should also show were you register your object
properties, it is
possible you made a mistake there.

The properties are registered in the class_init function:

static void
gst_blinkysrc_class_init (GstBlinkySrcClass *klass)
{
  GObjectClass *gobject_class;
  GstElementClass *gstelement_class;

  gobject_class = (GObjectClass*) klass;
  gstelement_class = (GstElementClass*) klass;

  parent_class = g_type_class_ref (GST_TYPE_ELEMENT);

  g_object_class_install_property (gobject_class,
ARG_SILENT,
    g_param_spec_boolean ("silent",
"Silent", "Produce verbose output
?",
                          FALSE, G_PARAM_READWRITE));
  g_object_class_install_property (gobject_class,
ARG_BL_DEVICE,
    g_param_spec_string ("device",
"Device", "Blinky device to get data
from.",
                          "0",
G_PARAM_READWRITE));
  g_object_class_install_property (gobject_class,
ARG_BL_SYNCHRONIZE,
    g_param_spec_boolean ("sync",
"Synchronize", "Synchronize with
blinky device ?",
                          FALSE, G_PARAM_READWRITE));

  gobject_class->set_property =
gst_blinkysrc_set_property;
  gobject_class->get_property =
gst_blinkysrc_get_property;

  gstelement_class->change_state =
gst_blinky_src_change_state;
}

I used a plugin template perl script made by Luca Ognibene
to generate
the skeleton of my plugin.

Thx,
Corentin.
