Can't it just play the 1440x1080 source in a 1440x810 window, using the hardware overlay? If that's not possible, wouldn't it be more efficient to down-scale vertically to 1440x810? Do you have "-vf screenshot" in command line or config parameters? I suspect you've specified that and it's what triggers the swscaler output.
