Посоветуйте рецепт.
На android при воспроизведении видео и когда стоит на паузе (на паузе чащее) красный меняется на синий, сниний на красный, остоьно в глаза не бросается
прилогаю видео https://www.youtube.com/watch?v=17jiHAD1SBk
Баг за метин начиная с 1 минуты 10 секунды. Поставил на паузу специально па паузу чтоб быстрее поймать. Таоке происходит произвольно при просмотре любого видео, на разные отрезки времение с частастью до 2-5 минут.
Ставил лолипоп тоже самое
Подкючал к компьютеру через AmbiBox, никаких вышеописаных проблем нет!
Описание
- Светодиодная лента Ws2812b 5050 60\м (на данный момент 111 диодов, но пробовал и на 60)
