Ошибка mpeg_decode_postinit ()

Я пытаюсь сделать несколько миниатюр с помощью команды ffmpeg. Мой файл называется «aaa.ts», и я хочу делать миниатюры каждую секунду.

Честно говоря, это работает, но у меня есть 4 красные линии в терминале. Можете ли вы сказать мне, какие у меня проблемы, и дать мне несколько решений?

Моя команда была:
ffmpeg -i aaa.ts -r 1 screenshot%03d.png

Это делает некоторые pngs в каталоге, но первые два или три полностью серые, и выходные данные команды содержат эти четыре ошибки.

1. [mpeg2video @ 0x24bed10] mpeg_decode_postinit () ошибка
2. [mpeg2video @ 0x24bed10] предупреждение: первый кадр не является ключевым кадром
3. [mpeg2video @ 0x24bed10] ac-tex поврежден в 31 60
4. [mpeg2video @ 0x24bed10] Предупреждение о MV недоступно
