Hi, I am a newbie to ffmpeg. But, I have noticed lately that ffmpeg’s “-ss xx:xx:xx” option is totally broken and “-t 0:02:00” (without -ss) will result continuing encoding but no sound after 2 minutes. If there are tickets for these problems, just silently ignore this. Thanks, Namsuk Kim/김남석 R&D/기술 개발실, WMG Ltd.
