Я создал видео слайд-шоу из изображений.
Из документов сказано:
В этом примере каждое изображение будет иметь продолжительность 5 секунд (обратная сторона 1/5 кадров в секунду).
ffmpeg -framerate 1/5 -i img%03d.png -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4
Но когда я запускаю команду, картинка показывает 2 секунды, а затем 3 секунды ничего, а затем следующую картинку.
