Возникла проблема с организацией стримов с камер, буду благодарен за любую помощь.
ffserver version 2.6.3 Copyright (c) 2000-2015 the FFmpeg developers
Есть две вебкамеры, есть ffserver. Конфиг такой:

По одиночке камеры работают отлично. Но стрим идёт исключительно с одной камеры, пытаюсь запустить сразу с двух - со второй падает сразу же при запуске ffserver:
