Последняя версия, 7.0.2-static, правда не знаю почему Debian 8.3.0-6, когда OC ubuntu.
Трудность в том, что на одном из 2 видеопотоках. Происходит какое то несоответствие соотношением сторон.
Не понимаю как так получается, когда входной файл один и соотношение сторон должно быть верным.
Предположим, если взять 10 видео. То примерно 2-3-4 видео будут обработаны, остальные ошибку выдадут.
