I'm building in Unity, 5.1.4f1 (32 bit) with Vuforia 5.0.10, testing on a Galaxy Note 4.
Everything was working fine for a while, until the video started streching at a crazy rate, maybe 3 to 4 times zoomed in on one axis only, making a very stretched video.
Nothing I did fixed it, short of starting over from scratch with a new project in Unity, which I did and then it was back to normal - for a while. Now it has happened again, but this time it is strectched both horizontally and vertically so that the aspect ratio is OK, but the camera image is zoomed in about 3 or 4 times.
I've read through other threads talking about the devices not having the right definition, but in my case, the Note 4 is pretty common, and it *was* working perfectly for a while beforehand. Anyone know what might be going wrong and/or how I could reset it? LIterally nothing to do with the AR camera or tracker was changed between the builds where it stopped working properly.
