Tracking time for which a pipeline has been in Playing state.

[Yogesh Marwaha]

Found the root cause of the problem.

gst_element_get_base_time(m_pPipeline) is only updated when pipeline is put
to Playing state. So, when the pipeline is in Paused state my code fails and
when the pipeline is again put to Playing state base time is update and
elapsed time is calculated correctly.

So, I'll have store elapsed time and only update it if in Playing state. OR
implement all these things on my own. Lets see what I do in the coming
weekend.

PS: My app can only (presently) rip audio cds. You can download latest svn
snapshot from
