есть такой код: он считывает с камеры данные и пишёт их на диск в видео-файл вопрос такой - как организовать процесс получения от камеры последовательности изображений(кадров) в какой-нибудь класс для дальнейшей их обработки? (системой искуственного зрения) я честно не понимаю что происходит после инициализации камеры - и вот интересует: что из этого нужно колупать и как? | Код | static void run(int i){
