 Stop. That's your problem.

 In your segment, you're saying "the valid range of buffers to follow will be
from 16:30:00.00 onward" ... and then you give buffers which are not within
that range.

 If you want to convey a specific stream time (which is maybe what you want if
that element is handling seeks), use the segment.time field for that, and then
just set segment.start to 0 and the first buffer PTS to 0.
