      Rework forward txfm/quantization skip system in RTC coding mode · 7428cebe
      Jingning Han authored
      This commit allows more aggressive decision to skip forward
      transform and quantization for luma component in RTC coding mode.
      The chroma components remains going through the normal coding
      routine, since they are not included in the non-RD mode search
      process.
      
      It reduces the runtime cost by 2% - 10%. In speed -6,

      The compression performance of speed -6 is improved by 0.44% in
      PSNR and 1.31% in SSIM.
