про звук не знал. В моей камере качество звука плохое, поэтому не пригодится.

создал, вроде помогло, но эта ошибка всё же промелькнула, не понял в какой момент. Наблюдаю.
2) если запустить через vlc
Консоль
$ cvlc v4l2:///dev/video1
то он долго думает (минуту примерно), при этом пишет:
Консоль

затем появляется окно, камера работает, картинку видно.
При следующих запусках точно также.
А если через mplayer
Консоль
$ mplayer -tv driver=v4l2:device=/dev/video1 tv://
тогда сразу появляется окно, в окне всё зелёное и картинки нет,
при этом в консоли:
