The hls_time is set to the segments duration, not target duration, and the hls_time just a reference value, so the target duration is +1. anyway, this patch can not catch the point. The spec clearly says it has to be greater or equal. So rounding it up is perfectly legal and might even safeguard against some poor player implementations. > > Thanks, > Karthick > > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
