      Fast computation path for forward transform and quantization · ccba289f
      Jingning Han authored
      This commit enables a fast path computational flow for forward
      transformation. It checks the sse and variance of prediction
      residuals and decides if the quantized coefficients are all
      zero, dc only, or more. It then selects the corresponding coding
      path in the forward transformation and quantization stage.
      
      It is currently enabled in rtc coding mode. Will do it for rd
      coding mode next.
      
      In speed -6, the runtime for pedestrian_area 1080p at 1000 kbps
      goes down from 14234 ms to 13704 ms, i.e., about 4% speed-up.
      Overall coding performance for rtc set is changed by -0.18%.
