Я пытаюсь захватывать кадры с ip-камеры для обработки изображений, я использую HeadlessMediaPlayer для воспроизведения медиа с камеры и получаю BufferedImage в функции обратного вызова. Но он всегда останавливает воспроизведение после нескольких воспроизведенных сцен, затем программа завершается без исключения. Вот вывод консоли:
