But for the above pipeline i written application .

            In application u can not directly link demuxer with decoder because demuxer has dynamic pads which are created  on the basis of the availability of the stream present in container format .  

         so u need to link the dynamic src pad of the demuxer with decoder's sink pad in a callback . 

        U can refer this link http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/chapter-pads.html#section-pads

If your intention is just to playback, you should use playbin2
