Unable to put caps on audioconvert & audioresample.

[Sagar]

Hi,

the following is the code which i am trying to run (removed callback method
before posting)

I get this error when I try to run this code. *assertion failed:
(gst_element_link_filtered (audioconvert1, audioresample,caps))*

I am confused between caps and capsfilter as you can see in my code I am
using both of them
