Michael, is this a correct description of your filter?

  pp7[=qp[:mode]]
    Variant of the spp filter, similar to spp=6 with 7 point DCT where
    only the center sample is used after IDCT.

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

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

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