'Normal' alpha uses this formula to mix the framebuffer and video: output = fb pixel * fb alpha + video pixel * (1 - fb alpha) and the 'inverted' alpha uses this formula: output = fb pixel * (1 - fb alpha) + video pixel * fb alpha Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- Reading git-diff-tree failed
