I'm wanting to have a blank screen, and when something happens, a video plays. When the video ends, back to blank screen.
I nearly have that, but with short flashes of boot messages in the back ground.
if something happens:
The flashes of the boot messages happen between the play movie and blank screen commands I suppose.
I'd rather leave the boot messages there because they're useful for debugging, but I suppose I can configure the pi to keep them quiet.
I'm trying to work out where linux is keeping the contents of the original frame buffer, so I can flush that too. Any ideas?
