[Tracker] unable to activate tracker support for tagreadbin

[Jackson Lawson <jacksonlawson55 yahoo com>]

Hi,

 i am trying to use tagreadbin supported by tracker, but somehow not able to find out to enable tagreadbin in 
gstreamer. I have had installed all the available plugins (bad & ugly)... but with no success :(

would u plzz recommend where should i get tagreadbin or how to enable it in gstreamer? 
or is this a third-party plugins developed for their specific appl. & not shifted with gstreamer packages, 
and therefore left with  decodebin and playbin options only?

Regards,
Jackson
