Gets the last stream time of pipeline. If the pipeline is PLAYING,
the returned time is the stream time used to configure the element's
base time in the PAUSED->PLAYING state. If the pipeline is PAUSED, the
returned time is the stream time when the pipeline was paused.
This function returns GST_CLOCK_TIME_NONE if the pipeline was
configured to not handle the management of the element's base time
(see gst_pipeline_set_new_stream_time()).
