      Adjust key frame quantization index for rtc coding · 2536a89a
      Jingning Han authored
      This commit slightly increases the bit allocation for key frame. This
      improves speed -5 coding performance by 2.77% with aq-mode=0 and by
      2.78% with aq-mode=3.

      Adjust rate allocation in non-RD coding mode · 751d002f
      Jingning Han authored
      This commit reduces the frequency of frames using finer quantizer
      in non-RD coding flow, and slightly tune up the quantizer resolution
      when used. It provides 1.7% compression gains in speed -5 at no speed
      difference.

      Add speed feature for recode tolerance. · 769cd78f
      Paul Wilkins authored
      The new tolerance is a little higher than before (especially
      for kf/gf/arf) so this change gives an encode speed up
      for some clips up for speeds 0-2.

      Adjust rt speed steps. · 6fc20a84
      Yaowu Xu authored
      This commit adjusted the speed steps in rt mode to make the steps
      more evenly spaced on speed and quality, specifically:
      1. Merged 3 and 4 into one single step 3 and removed confilicting
      features.
      2. Move 8, 7, 6, 5 to be 7, 6, 5, 4 repsectively.
