      Separate rate-distortion modeling for DC and AC coefficients · 7c45dc98
      Jingning Han authored
      This is the first step to rework the rate-distortion modeling used
      in rtc coding mode. The overall goal is to make the modeling
      customized for the statistics encountered in the rtc coding.
      
      This commit makes encoder to perform rate-distortion modeling for
      DC and AC coefficients separately. No speed changes observed.
      The coding performance for pedestrian_area_1080p is largely
      improved:
      
      speed -5, from 79558 b/f, 37.871 dB -> 79598 b/f, 38.600 dB
      speed -6, from 79515 b/f, 37.822 dB -> 79544 b/f, 38.130 dB
      
      Overall performance for rtc set at speed -6 is improved by 0.67%.
