How to reproduce: {{{ % ffmpeg -i sub.srt sub.ass ffmpeg version n6.0 Copyright (c) 2000-2023 the FFmpeg developers built with gcc 13.2.1 (GCC) 20230801 }}} sub.srt (input): {{{ 1 00:00:29,566 --> 00:00:34,332 test 1 2 00:00:34,333 --> 00:00:38,833 test 2 3 00:00:38,833 --> 00:00:39,833 test 3 }}} sub.ass (actual output): {{{ ...
