У меня проблема с преобразованием несжатых файлов AVI с помощью ffmpeg. Я могу конвертировать .mp4 видео без проблем, но когда я пытаюсь запустить ту же команду на несжатом .avi все выглядит нормально, но я получаю сообщение об ошибке в Windows Media Player и пустое видео в QuickTime, когда я пытаюсь воспроизвести выходной файл , Вот команда, которую я использую:
ffmpeg -i "Uncompressed.avi" -c:v libx264 -t 00:00:20 -crf 22 -preset superfast -an test.mp4
И вот полный вывод этой команды:

У меня такое ощущение, что мой AVI-файл слишком большой. Это чуть более 2 минут и 19,9 ГБ. Я пробовал это на двух похожих файлах AVI с одинаковым результатом. Любые идеи о том, что я должен попытаться решить эту проблему?
