[gst-devel] !GST_IS_OBJECT Problem

[Erwan Masson]

Thank you for the tips.
Unfortunately, if I remplace by this:

> if (!GST_IS_MINI_OBJECT(mini_obj))
>                          g_print("mini_obj is not an object T_T");
>                      else{

> |",gst_object_get_name(mini_obj));
>                         g_print("name object pad %s |",
> gst_object_get_name(pad));

I got theses errors:

So the mini_obj is a miniobject, but if I try to use it, I got theses error.
If I use the pointer, I got a segmentation fault.

After a few test, It seems all my callbacks have the same problem: the
second parameter is wrong, whereas the first parameter and third parameter
is good(notify::caps, have-type, handoffs, have-data).
