[karmendra jain]

Thanks a lot

If possible(whenever u got time ..) .. Can u explain how its happning
****what i have done now is ****
gst_pad_add_buffer_probe(mypad,G_CALLBACK(mycallback), mypad)

and static gboolean mycallback(GstPad *pad, GstMiniObject *obj,
gpointer user_data)

**so my doubt it *** ---->how the GstMiniObject is gettin filled ???
