FFMPEG - Зеленый оттенок с изображением Spla sh в видео

Question

Я использую FFMPEG для создания видео, состоящего из одного моноблока chrome Изображение в формате JPG:

ffmpeg -y -loop 1 -framerate 30 -t 5 -i SplashBW.jpg Splash.mp4

Есть две проблемы с итоговым видео:

• При просмотре с помощью VL C он имеет зеленый оттенок
• При просмотре с помощью «Кино и ТВ» (я подозреваю, что это программа просмотра Windows 10 - ассоциация для файлов MP4, похоже, была взломана на моем P C) он имеет зеленый оттенок и преобладающее мерцание каждые 0,5 секунды или около того.

При просмотре через Irfan View выглядит нормально. Я не знаю, связана ли проблема с исходным JPG, командой FFMPEG или программами просмотра. Естественно, я хочу, чтобы он правильно отображался на всех выходах.

Первые две ссылки ниже выглядят нормально в моем браузере (Chrome), когда я их открываю. Третья ссылка - это запись экрана того, что я вижу, когда пытаюсь воспроизвести видео с помощью приложения Film and TV.

Answer 1

Ваше входное изображение имеет только один компонентный канал - яркость. Большинство плееров имеют дело с потоками H.264, содержащими три компонентных канала - яркость или «яркость» (Y) и два для цветности или «цвета» (U и V). Когда кодер H.264 кодирует поток только для яркости, он сохраняет его, используя синтаксис, с которым многие проигрыватели плохо справляются. Итак, мы говорим ffmpeg добавить компоненты цветности, которые будут иметь нейтральные значения (поскольку в источнике нет валентности цвета), прежде чем отправлять их в кодировщик. Мы добавим наиболее распространенную форму кодирования YUV - yuv420p.

Итак,

ffmpeg -y -loop 1 -framerate 30 -t 5 -i SplashBW.jpg -pix_fmt yuv420p Splash.mp4
