That's the different between 1.14 and 1.16. I've wondering if I should kept an alias for this case, but we decided not to pollute the registry with that. The argument was the video8 is not predictable. sometimes just plugging some UVC camera, or a change in kernel timing will swap the videoN nodes. Hope this is fine, for simple cases like Exynos and i.MX6 that should work. p.s. also, remember the registry is cached, it could not be impossible that there still some potential cache stalls as tracking the movement in /dev isn't very reliable. > > Thanks
