Including identity element

[Mayank Agarwal]

Hi,

I have taken gstreamer tutorial 2 and adding identity element in following way:

g_object_set(data.sink, "signal-handoffs",true,NULL);

   g_signal_connect(data.sink, "handoff",

                    G_CALLBACK(handoff), pipe);

and in the handoff implementation i want to calculate frame rate from timestamp
how can im implement handoff callback to get timestamp info:


handoff(GstElement *object,

        GstBuffer *arg0,

        GstPad *arg1,

        gpointer user_data)

{

   GstPipe *pipe;


   printf("handoff : %p\n", arg0);

   gst_buffer_ref(arg0);

   /* how can i recover timestamp info here and any other video quality params*/

}
