While testing this via "-vf scale_npp=format=yuv420p,sharpen_npp" I discovered a weird issue where the last line of pixels was pink/purple, apparently missing the luma plane.

This turned out to be a bug in scale_npp, which returned frames with a height of 1088 instead of 1080 for a 1080p source. It was fairly simple to fix, and I also pushed that fix: http://git.videolan.org/?p=ffmpeg.git;a=commit;h=37745b49049d4dbb5aa4ea84bcc289ed511971f9
I'm just very surprised that nobody noticed this issue in such a long time.
