      Add 4-point DST to DAALA_DCT4 experiment · 573cf25f
      Monty Montgomery authored
      CONFIG_DAALA_DCT4 currently force-enables CONFIG_DCT_ONLY due to a
      missing 4-point DST.  The DST had not been included because it was a
      significant coding performance loss; this turned out to be a bug that
      has since been corrected.
      
      This patch adds a 4-point type IV DST to the DAALA_DCT4 experiment.
      There is a small coding performance loss in using the type IV over
      AV1's current type VII.

      Add CONFIG_DAALA_DCT8 experiment. · cf18fe4e
      Monty Montgomery authored
      This experiment replaces the 8-point Type-II DCT and 8-point Type-IV DST
       scaling vp9 transforms with the 8-point orthonormal Daala transforms.
      These have reduced complexity and are perfect reconstruction at the cost
       of a slightly worse coding performance.
      This is because the Daala transforms expect the input to be shifted by 4
       bits but the output scale of the vp9 transforms is only 3 bits.

      This experiment replaces the 4-point Type-II scaled-output vp9 DCT
       transform with the 4-point Type-II orthonormal Daala DCT transform.
      Right now the CONFIG_DAALA_DCT4 experiment depends on CONFIG_DCT_ONLY
       as it does not add an orthonormal 4-point DST.
