Re: Howto cleanup my gstreamer filter upon exit?

Sharath Mudalamane
Hello Stefan,all,
 
Thanks a lot for the inputs! This is exactly what i was looking for.
 
Now, i have implemented the gst_wow_finalize() in my filter. But, I can't see
it being called when i perform an gst_object_unref( my_filter_handle);
 
Please, let me know if i am missing something in the implementation. I have
added the portion of code that implements _finalize() below:
 
_____________________________________________________________________________
____
gstwow.c
_____________________________________________________________________________
____
 
 
 
/* forward declaration */
static void gst_wow_finalize (GObject *object);

.....

/* initialize the plugin's class */

static void gst_wow_class_init (GstWowClass * klass)

{

gobject_class = (GObjectClass *) klass;

..

gobject_class->finalize = gst_wow_finalize;

...

}

......
static void gst_wow_finalize (GObject *object)

{

GstWow *filter = GST_WOW (object);

g_print ("\n[gst_wow_finalize] filter <%p>\t", filter);

my_library_close (filter->h_library_handle);

}

....

_____________________________________________________________________________

thanks & regards,
Sharath Mudalamane

gstreamer elements are normal gobjects, so please refer to the gobject =20
documentions (there is a tutorial part of the api docs) and read about =20
dispose() and finalize().
