the buffer timestamp position in the segment is supposed to be
updated by elements such as sources, demuxers or parsers to
track progress by setting it to the last pushed buffer' end time
(timestamp + #GstBuffer.duration) for that
specific segment. The position is used when reconfiguring the
segment with #gst_segment_do_seek when the seek is only
updating the segment (see offset).
