From a7bab199e50619df0a6d31a247f7186868e6e4e0 Mon Sep 17 00:00:00 2001 From: Steven Liu Date: Wed, 29 Apr 2020 20:39:22 +0800 Subject: [PATCH] avformat/hlsenc: compute segment duration use current pts minus last segment end pts 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..
