I'm using Vuforia 5.5.9 and Unity 5.3.4f1.
I'm using the Video Playback Sample code and I'm getting solid white video on playback.
Seems specific to iPads as I was getting correct playback on an iPod Touch.
I also seem to have correct playback on android with the Samsung Galaxy Tab 3 (which is the only android device I have).
I've tried a few of the suggested fixes for white videos from elsewhere on the forums and no luck.
changing the shader to "Geometry" didn't work. and changing the rendering path in unity didn't work.
Any help would be appreciated.
