Hi Ok, thanks.
Does this mean that mplayer should call vaPutSurface() twice? The first time with VA_TOP_FIELD and the next second with VA_BOTTOM_FIELD? Or is this handled by the backend? If I understand bob deinterlacing correctly it can be done by doubling the frequency and show the top field every second time and the bottom field every second time.
