For the "received" PTS, you need to also track the segment (if you use
the GstSample, the segment is contained, gst_sample_get_segment ()).
You can then transform the PTS into running-time, using
gst_segment_to_running_time(). This will give you some monotonic time,
that starts from 0, and correlate with the pipeline clock. The Pipeline
base_time (gst_element_get_base_time()) which is available on any
active GstElement matches the clock time at running time 0.
