Previously we where assuming x264 was wrong, that PTS == DTS on key frame. So
we where shifting DTS up to "fix" it, that was just more wrong. Now, the
problem is that if first input has PTS 0, then it means that first DTS will
most likely be negative. We don't support this in GStreamer.

Now, as I mention, this forward shift need to be compensated somewhere, just
didn't have time to handle it yet. I need to review the entire segment clipping
code to make sure everything sane (my first look told me there would be few
bugs along the way).
