dashenc: separate segments based on current segment duration
The current implementation creates new segments comparing
pkt->pts - first_pts > nb_segs * min_seg_duration
This works fine, but if the keyframe interval is smaller than "min_seg_duration"
segments shorter than the minimum segment duration are created.
Example: keyint=50, min_seg_duration=3000000
segment 1 contains keyframe 1 (duration=2s < total_duration=3s)
and keyframe 2 (duration=4s >= total_duration=3s)
segment 2 contains keyframe 3 (duration=6s >= total_duration=6s)
segment 3 contains keyframe 4 (duration=8s < total_duration=9s)
and keyframe 5 (duration=10s >= total_duration=9s)
...
Segment 2 is only 2s long, shorter than min_seg_duration = 3s.
To fix this, new segments are created based on the actual written duration.
Otherwise the option name "min_seg_duration" is misleading.
