Sorry I make a mistake, the pkt should not in current segment, it should in the 
next segment, so just remove the + vs->dpp
I will submit version 2 patch

[FFmpeg-devel] [PATCH] avformat/hlsenc: compute segment duration use current pts minus last segment end pts

2020-04-28 Thread Steven Liu
segment duration is using vs duration which compute by frame per second,
that can not fix problem of VFR video stream, so compute the duration
when split the segment, set the segment target duration use
current packet pts minus the prev segment end pts and plus current
packet's duration.
