Добрый день!

Пробую кучу утилит и сервисов для восстановления одного видео из отпуска. На GitUp Git2 писал видео отрывками, используя функцию паузы записи (назначив её на боковую клавишу), а по окончании забыл нажать на кнопку полного окончания записи, сразу выключив камеру (хотя запись была на паузе).

Утилиты и сервисы видеопоток восстанавливают хорошо, не исключение и ваша программа. Но вот со звуком беда.
Например, после утилиты звук recover_mp4 какой-то рваный, с паузами, а местами и вовсе ускоренный (даже в плеере секунды бегут быстрее), и если потом муксовать ffmpeg'ом h264 и aac потоки, то в итоговом видео вообще никакой синхронизации - звук кончается на пару минут быстрее видео. Но на данный момент - это самый лучший результат, если говорить о звуке.
Есть ещё сервис fix.video - там в тестовом бесплатном сэмпле восстановленного файла слышно всего пару каких-то щелчков первую секунду, а далее вообще нет звука.
Пока пишу этот issue - жду окончания обработки видео на сервисе restore.media - это как раз монетизационная онлайн-версия утилиты recover_mp4.

Конкретно с вашей программой aacfixer возникает "Ошибка сегментирования":
