      Use source frame difference to make partition decision · 4e66293f
      Yunqing Wang authored
      Calculate the difference variance between last source frame and
      current source frame. The variance is calculated at 16x16 block
      level. The variances are compared to several thresholds to decide
      final partition sizes.
      
      An adaptive strategy is implemented to decide using
      SOURCE_VAR_BASED_PARTITION or FIXED_PARTITION based on motions
      in the video. The switching test is done once every
      search_type_check_frequency frames.
      
      The selection of source_var_thresh needs to be investigated
      further later.
      
      RTC set Borg test showed 0.424% overall psnr gain, and 0.357%
      ssim gain. For clips with large enough static area, the
      encoding speedup is around 2% to 15%.

      Select prediction filter type in non-RD mode decision · 06ec873f
      Jingning Han authored
      This commit allows the non-RD mode decision flow to  select
      prediction filter type in NEWMV mode. It provides 8.14% compression
      performance gains in both settings of AQ=0 and 3. The current speed
      impact is about 5% to 10% slower.

      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
      cost.
      
      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.

      Motion referenced partition search for non-RD coding flow · abdb0650
      Jingning Han authored
      This commit enables the non-RD mode decision coding flow to
      adaptively apply partition search in non-refresh frame, when the
      collocated block in previous frame suggests there might be a motion
      activity. It refactors the update_state_rt() function to support
      buffer swap of mode_info struct, thereby unifying the encoding
      stage across various non-RD coding modes.
      
      It provides 5% compression performance gains in speed -6 for rtc
      test set, at about 12% speed slow down.

      Yaowu Xu authored
      This commit added a speed feature to make the logic of calculating
      skip_recode on a block level more explicit. This also enable the
      feature to be enabled at speed 5 where the previous logic is too
      conservative, help gain back the lost speed for --rt(-5).

      Fix bad speed settings interaction. · 2e05341a
      Paul Wilkins authored
      The flag x->skip_recode interacts badly with
      the cpi->sf.use_nonrd_pick_mode and
      cpi->sf.skip_encode_sb speed settings.
      
      Restricting the use of the skip_decode flag when
      these other speed choices are in use helps quality
      for speeds 3 and 4 by a large amount with only a
      small impact on speed.
      
      Average improvmentes for 2 pass speed 4:
      Derf +8.8%
      Yt + 10.53%
      Std-Hd +6.95%

      Enable variable block size test in non-RD mode decision · 60f9ebc3
      Jingning Han authored
      This is an initial attempt to allow variable block size partition
      in non-RD coding flow. It tests 8x8, 16x16 and 32x32 block size per
      64x64 block, all using non-RD mode decision and the associated rate
      distortion costs from modeling, then selects the best block size to
      encode the entire 64x64 block. Such operations are triggered every
      other 3 frames. The blocks of intermediate frames will reuse the
      collocated block's partition type.
      
      It improves the compression performance by 13.2%. Note that the gains
      are not evenly distributed. For many hard clips, the compression
      performance is improved by 20% to 28%. Local speed test shows that
      it will also increase runtime by 50%, as compared to speed -7. It is
      now enabled in speed -6 setting.
