'playbin' gstreamer plugin missing

[Ashish Kumar Mishra]

Dear  All , 

I hadn't installed other gstreamer-plugins ( BAD , BASE , UGLY , GOOD etc ) 
I have installed them now. Even after installing all Gstreamer Core +
Plugin's  below is the mentioned problem :-
It seems all the plug-ins are properly installed , but still the application
fails to create an instance of elements.
Like decodebin / videoconvert / videoscale etc. 

*1) GST-INSPECT detects the plugin    *
~: gst-inspect-1.0 | grep “videoconvert”
autoconvert: autovideoconvert: Select color space convertor based on caps
videoconvert: videoconvert: Colorspace converter
~:
~: gst-inspect-1.0 | grep “decodebin”
playback: uridecodebin: URI Decoder
playback: decodebin: Decoder Bin
~:
~: gst-inspect-1.0 | grep “videoscale”
videoscale: videoscale: Video scaler


*2) But the application fails to create an instance of elements :-*
