Hi Sudarshan,
No, i am not handling it.
my idea was when the end of stream comes from the filesrc , the pipeline
is chsnged to NULL state through PAUSED and READY state. So i thought i need
not handle that. Can you tell me how can i handle it ?
Regards,
~Arnab

Hi Zhang ,
Thanks for your reply
Did you mean the following in the _class_init ( ) ?
If so then yes, i have done that .
static void gst_queue3_class_init (Gstqueue3Class * klass)
{
GstElementClass *gstelement_class;
gstelement_class = (GstElementClass *) klass;
gstelement_class->change_state = GST_DEBUG_FUNCPTR
(gst_queue3_change_state);
}

Hi, gstreamer-devel:
Did you override the `change_state' function pointer in your
element's `_class_init' function?

Hi All,
during state change of my plug in i am calling a function
QUEUE3_De_Init()
but its not getting called .
QUEUE3_De_Init() de-initializes all the initialized variables
in the code.
the implementation is as such
static GstStateChangeReturn gst_queue3_change_state
(GstElement * element,
GstStateChange transition)
{
Gstqueue3 *queue3;
abuffer = GST_QUEUE3 (element);
GstStateChangeReturn ret = GST_STATE_CHANGE_SUCCESS;
switch (transition) {
case GST_STATE_CHANGE_NULL_TO_READY:
break;
case GST_STATE_CHANGE_READY_TO_PAUSED:
break;
case GST_STATE_CHANGE_PAUSED_TO_PLAYING:
break;
default:
break;
}
ret = GST_ELEMENT_CLASS (parent_class)->change_state
(element,
transition);
switch (transition) {
case GST_STATE_CHANGE_PLAYING_TO_PAUSED:
break;
case GST_STATE_CHANGE_PAUSED_TO_READY:
break;
case GST_STATE_CHANGE_READY_TO_NULL:
QUEUE3_De_Init();
break;
default:
break;
}
So,
can please somebody tell me how and where I can call the
function when am
changing the state of the pipeline ?

Arnab
