Короче говоря, я просто хочу создать видео из числа изображений X и файла mp3 и получить такое же качество звука.
Я проверил сайт ffmpeg, но ... вот что у меня есть:
ffmpeg.exe -y -i img%01d.jpg -i "03 eminem - when I'm Gone.mp3" -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest shortt.mp4
Где: В той же папке у меня есть img0.jpg img1.jpg и так далее ...
MP3-файл - это аудиофайл.
Вывод должен быть сохранен в shortt.mp4
После того, как я запустил эту команду, потребовалось около 2 секунд, и вот результат:
C:\Users\icebox\Desktop>ffmpeg.exe -y -i img%01d.jpg -i "03 eminem - when I'm Go
ne.mp3" -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest shortt.mp

Файл есть, но если я открою его в VLC, то ничего не произойдет.
Я попробовал это без кратчайшего аргумента. Я ждал около 5 минут, чтобы закончить, но он не закончился, поэтому я остановил его.
Вот что я получил:
[swscaler @ 0653e000] устаревший формат пикселей, убедитесь, что вы правильно установили диапазон. Есть предложения?
PS: Мне также удалось создать видео с изображением и аудиофайлом, но оно не проходит по всем изображениям.
