#7044: hls duration incorrect with split filter

-------------------------------------+-------------------------------------
I'm trying to encode two video streams into an HLS file (fill & alpha).
However, when I use the split filter (which I need for this) the segment
durations in the manifest file becomes x2 (30s) vs the actual duration
(15s).
