  "message": "daala_tx: New flattened 2-point Type-IV DST.\n\nThis 2-point Type-IV DST uses the same computation graph as the\n asymmetric 2-point Type-IV DST.\nBecause this transform is embedded, it may be possible to remove the\n initial averaging step by splitting the 2-point Type-IV DST into\n separate forward and inverse transforms.\nThis change also reduces two multiplication constants (forward and\n inverse transform) so they are less than 1.\n\nsubset-1:\n\nnew_dst2a@2017-12-04T01:59:12.884Z -\u003e new_dst2@2017-12-04T01:59:57.412Z\n\n   PSNR | PSNR Cb | PSNR Cr | PSNR HVS |    SSIM | MS SSIM | CIEDE 2000\n-0.0126 |  0.0387 |  0.0441 |   0.0554 | -0.0301 |  0.0034 |    -0.0342\n\nChange-Id: I98568e0c5b97e3a6af27653ddab845ce97d2a53d\n",
