videoaggregator: fix buffer selection when duration=-1

If the src framerate and videoaggreator's output framerate were
different, then we were taking every single buffer that had duration=-1
as it came in regardless of the buffer's start time.  This caused the src
to possibly run at a different speed to the output frames.
