Добрый день,

Подключил камеру Trust 17003 (USB 2/0). На выходе получаю очень сильную яркость, такое впечатление, что драйвер не тот или кодык какой-то не тот запускается. Пробывал через разные приложения VLC и mplayer - менять яркость, контрактность, но результатов не дало. Интересно то, что в темной комнате картинка более-менее (но цвета перемешаны)

mplayer tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0 -fps 30
