And the duration of my video source is 00:01:29, output 3 segments is 00:01:01, 00:00:58, 00:00:58, and the total is 00:02:57.
And I try to do the same operation in old ffmpeg version(N-46474-gdb012e1), it came out the right segments 00:01:00, 00:00:29.

This command produces this M3U8 file which is not supposed to do:
#EXTM3U #EXT-X-VERSION:3 #EXT-X-MEDIA-SEQUENCE:0 #EXT-X-ALLOW-CACHE:YES #EXT-X-TARGETDURATION:13 #EXTINF:10.200000, istikbal0.ts #EXTINF:9.800000, istikbal1.ts #EXTINF:11.080000, istikbal2.ts #EXTINF:12.440000, istikbal3.ts #EXT-X-ENDLIST
HTTP Live Streaming Specification states that TARGETDURATION is REQUIRED to be set correctly and all segments should follow it.
I mean, this bug is critical, I think.
Thank you
