Is there anymore progress on this issue? I have been testing on both android and windows and they each have their own issues. All of my videos fade to white... With android if I shut off the surface view as described and put a region behind my video region with a solid white graphic I only get a quick black flash between videos. On windows even if I put a white graphic behind my video I get a flash to the background image of the layout then a flash to black and then the new video.
I would prefer to continue using the intel compute sticks I have been using as they are smaller than the android boxes. However, I plan to have long strings of short 30 second videos and whatever can be down to minimize that flash is of great importance. If it means having to go with android that is what I will do.
