      Enable Hadamard transform based cost estimate for all block sizes · 9922e434
      Jingning Han authored
      This commit turns on the Hadamard transform based rate distortion
      estimate for all block sizes in RTC coding mode. It conditionally
      skips the rate distortion estimation if all zero block flag is set
      on. No significant encoding speed change is observed. The
      compression performance of speed -6 is improved by 1.7% over using
      it only for block sizes of 32x32 and below.

      Account for eob cost in the RTC mode decision process · 60e01c65
      Jingning Han authored
      This commit accounts for the transform block end of coefficient flag
      cost in the RTC mode decision process. This allows a more precise
      rate estimate. It also turns on the model to block sizes up to 32x32.
      The test sequences shows about 3% - 5% speed penalty for speed -6.
      The average compression performance improvement for speed -6 is
      1.58% in PSNR. The compression gains for hard clips like jimredvga,
      mmmoving, and tacomascmv at low bit-rate range are 1.8%, 2.1%, and
      3.2%, respectively.
