Kompу меня есть несколько видеофайлов, которые я хочу объединить вместе, после того, как я ускорю 2-минутный раздел видео (его неинтересные 2 минуты, но ускорили это будет хорошо, и не потерять непрерывность.)
При попытке объединить отредактированный файл с другими происходит сбой. Вот пример произведенной ошибки.
[mp4 @ 0x103b180] Non-monotonous DTS in output stream 0:0; previous: 22228547, current: 7750549; changing to 22228548. This may result in incorrect timestamps in the output file.
Я получаю эту ошибку при выполнении этой команды:
ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4
Я только что издал это:
ffprobe -select_streams a -show_entries stream=time_base -of compact=p=0 newout8.mp4
и выход внизу:

это один из файлов, с которыми мне нужно объединить(concat).
Я использовал:

как я понимаю, мне нужно перекодировать короткий клип (newout8.mp4), то файлы будут сливаться красиво.
Кроме того, ffmpeg выводит файл, но воспроизведение не работает правильно.

как вы видите выше, Ive сократил ошибки, ограничив его слиянием 3 файлов 2 неотредактированных, а отредактированный в середине (out8speed3).
Я попытался разместить сообщение об ошибке, но это было слишком много для поста ограничение в 30000 символов (как отмечалось выше).
вот ffprob для недавно отредактированного (я изменил Битрейт аудио на 127k, как и другие файлы, после редактирования клипа, ускоряя его с 2 минут до 15 считанные секунды.)
