      Rate ctrl changes to track target bitrates closer · 97f4fb7b
      Deb Mukherjee authored
      Turns off the DISABLE_RC_LONG_TERM_MEM macro and makes other changes
      in the way the bits are updated, to make 2-pass rate control track
      target bitrates closer.

      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

      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.

      Remove the q division by 3 for first frame. · 939f0e74
      Marco Paniconi authored
      This code/setting was actually not used (since speed features were not set on first frame,
      until a recent change) and should be removed.
      In CBR mode, the q value for the first frame can be controlled by setting
      the target size via the parameters rc_buf_initial_sz (and max_intra_size_pct).

      Apply finer quantizer to partition search frames in non-RD flow · 99893f24
      Jingning Han authored
      This commit optimizes the bit allocation for the non-RD coding flow.
      It applies slightly better quantizer to the frames, where all blocks
      run a non-RD partition search. Such frames typically have better
      rate-distortion trade off, thus improving the reconstruction quality
      for next few frames reference at reasonably low increment in rate
      The coding performance for rtc set at speed -5 with error-resilient
      tuned on and rate control set as cbr is improved by 19.58%. It improved
      the coding speed by about 10% for a portion of local test clips.

      Adds variance based fixed size partitioning · 10bae825
      Deb Mukherjee authored
      Adds a method for determining a fixed size partition based on
      variance of a 64x64 SB. This method is added to rtc speed 6.
      Also fixes a bug in rtc_use_partition() and includes some
      refactoring related to partitioning search, and some cosmetics.
      Currently compared to speed 5, the coding efficiency of speed 6
      is -19% and that of speed 7 is -55%, in cbr mode.

      Removes active_worst_quality feedback · d23e3392
      Deb Mukherjee authored
      Removes certain cases of feedback of active_worst_quality,
      and removes it from the RATE_CONTROL structure. Now active
      worst quality is expected to be computed locally in the
      q picking function during the encode.
      Making temporal filter strength depend on avg_frame_qindex
      rather than on active_worst_quality actually improves
      performance esp. for yt.

      Parameter fixes for one-pass non-cbr mode · b2209c33
      Deb Mukherjee authored
      Fixes some of the parameters for 1-pass non-cbr mode.
      Also includes some cleanups, inlcuding refactoring of the
      recode_loop options.
      Results on derfraw300 improve by about 5-6%, so that the one-pass
      mode is now 13% below the 2-pass mode in speed 0.

      Layer based rate control for CBR mode. · 4864ab21
      Marco Paniconi authored
      This patch adds a buffer-based rate control for temporal layers,
      under CBR mode.
      Added vpx_temporal_scalable_patters.c encoder for testing temporal
      layers, for both vp9 and vp8 (replaces the old vp8_scalable_patterns).
      Updated datarate unittest with tests for temporal layer rate-targeting.
