I'm using Vuforia with Cloud Recognition, when a Marker is recognitied the VideoPlayer appears and the Audio start, BUT che video is black. I'm using an .MP4 file that is displayed and played correctly if I just put a VideoPlayer in my Scene statically and I press Play. I tried to build on iOS and Android, but the problem it's the same. Anyone can help me?
I'm using Unity 2019.1.0f2 and the last version of Vuforia.
