Michael, is this a correct description of your filter?

    Variant of the spp filter, similar to spp=6 with 7 point DCT where
    only the center sample is used after IDCT.

      Force quantization parameter (default: 0, use QP from video).

      0: hard thresholding
      1: soft thresholding (better deringing, but blurrier)
      2: medium thresholding (default)

Maybe you can fill in a comment about medium thresholding..
