I use -ss and not -t. But thanks for the info. I can bypass the problem with -codec flac. Then it is accurate.
But it is strange anyway: _ffmpeg.exe -i _audio.flac -t 10 -codec copy _audio_2.flac —> it shows me 9.98 _ffmpeg.exe -i audio_2.flac -f null - —> but encode is 10.08 _ffmpeg.exe -i _audio.flac -t 20 -codec copy _audio_2.flac —> it shows me 19.96 _ffmpeg.exe -i audio_2.flac -f null - —> but encode is 20.06 And so on ... But: _ffmpeg.exe -i _audio.flac -t 10 -codec flac _audio_2.flac —> 10.00 Always accurate. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
