Debugging log

Here is the logs:

GLib-GObject-CRITICAL **: g_param_spec_boxed: assertion 'G_TYPE_IS_BOXED (boxed_type)' failed

GLib-GObject-CRITICAL **: g_object_class_install_property: assertion 'G_IS_PARAM_SPEC (pspec)' failed

GLib-GObject-WARNING **: ../gobject/gsignal.c:1674: parameter 2 of type '<invalid>' for signal "GstGLImageSinkBin::client_draw" is not a value type

GLib-GObject-WARNING **: ../gobject/gsignal.c:1674: parameter 2 of type '<invalid>' for signal "GstGLImageSink::client_draw" is not a value type

GLib-GObject-CRITICAL **: g_object_class_install_property: assertion 'G_IS_PARAM_SPEC (pspec)' failed


After exporting:

export G_DEBUG=fatal_warnings

Here is the fist line that causes the error (gstglsinkbin.c):

 
  g_object_class_install_property (gobject_class, PROP_LAST_SAMPLE,
      g_param_spec_boxed ("last-sample", "Last Sample",
          "The last sample received in the sink", GST_TYPE_SAMPLE,
          G_PARAM_READABLE | G_PARAM_STATIC_STRINGS));
