Yes, a Jinc36Resize on 1920x1080 frame would produce roughly 490MB worth (49 coeff * 4 bytes (float) * 1920x1080 pixel). That's why I don't even think about doing that. I guess I could add option for that. The precalculated coeff version could be simplify further by using integer operation instead of floating point (accepting a small rounding error).
Regarding the error, I guess it's because some reckless assumption I made concerning memory layout. Will have to investigate further.
