[gst-devel] Freeing application data from message

[Albert Costa]

Hi,
I have a plugin that generates custom application messages to be sent on the bus:

///////////
//INSIDE MY PLUGIN

  GstMessage* msg;
  GstStructure* structure;
  GstBus* bus = gst_element_get_bus(GST_ELEMENT(filter));

  MyInfo* myinfo = new MyInfo;
  /* do stuff with myinfo, including allocating internal data */

  structure = gst_structure_new("FILTERMESSAGE",
    "info", G_TYPE_POINTER, (gpointer)myinfo, 
    NULL); 
  msg = gst_message_new_application(NULL,structure);
  gst_bus_post (bus, msg);


On the other side, I have my application that watches the bus messages, and gets my info:
    case GST_MESSAGE_APPLICATION:
        const GstStructure *structure = gst_message_get_structure(message);
        MyInfo* info;
        info = (MyInfo*)g_value_get_pointer(gst_structure_get_value(structure, "info"));

All this works fine, but how can I free the resources allocated in myinfo structure? I can't release the strcuture that is owned by message, and I try to unref the message in the application then I get a 
 CRITICAL **: file ..\..\..\Source\gstreamer\gst\gstminiobject.c: line 359: assertion `mini_object->refcount > 0' failed

So how can I release my data?
Regards,
Al
