The problem is that the newsegment creation is just wrong for push-mode (and
needs serious cleanup for pull-mode).

Here is what the segment should be like for push-mode in bytes:
 start    : first observed PTS value (in your example that would be tinypts of
10s)
 stop     : last PTS you'll output (if you don't know, put GST_CLOCK_TIME_NONE)
 position : What the 'start' buffer value corresponds to in streaming time (0
in this case, it's the beginning).

for push-mode in time it would work slightly differently, in the sense that we
should be pushing out the newsegment we received from upstream and convert the
outgoing buffer timestamps based on an interpolation of capture time vs PTS
(i.e. estimating the remote transmission clock).
