      Port first pass stats handling from Vp9 into Av1 · da01c0dc
      Debargha Mukherjee authored
      Some parameter tuning included.
      lowres (q, 30 frames, speed 1):
      -1.243% av PSNR, -2.337% ov PSNR, +0.577% SSIM
      lowres (vbr, 30 frames, speed 1):
      -0.327% av PSNR, -1.007% ov PSNR, +0.182% SSIM
      A few videos become a lot worse in SSIM, which needs to be
      investigated. But PSNR-wise the patch seems pretty good.

      Remove aom_comp_mask_upsampled_pred from rtcd · f8daa92d
      Peng Bin authored
      Since aom_comp_mask_upsampled_pred just call aom_upsampled_pred
      and aom_comp_mask_pred, no need to separate c version from simd
      version any more.

      Fix txk-sel unit test failure in aq-mode · 1e79d90e
      Jingning Han authored
      The current aq mode encoder setting would alter the segment_id
      between the rate-distortion optimization and the block encoding
      stages. Disable the corresponding consistency check in this case.

      On a cif test sequence,
      encoder memory consumption decreases by 18% (380MB -> 312MB);
      decoder memory consumption decreases by 56% (21.4MB -> 9.4MB).

      Cleanup some fragile aspects of rd_pick_partition. · 00c6e6f7
      Urvang Joshi authored
      (1) Explicitly reset RD stats for each partition.
      PARTITION_SPLIT was the only one resetting the RD_STATS in 'sum_rdc'.
      But this was working because:
      - PARTITION_SPLIT was tried before VERT, HORZ, VERT_4 and HORZ_4; and
      - RD cost calculations in VERT, HORZ, VERT_4 and HORZ_4 partitions
      implicitly discarded existing value in sum_rdc
      However, that was very fragile; explicitly resetting the stats every
      time is much safer.
      (2) Using a separate variable 'temp_best_rd_cost' was fragile as someone
      may forget to update the same. So, we use best_rdc.rdcost directly.

      [jnt-comp, normative] Avoid double-rounding in prediction · 39cf8061
      David Barker authored
      As per the linked bug report, the distance-weighted compound
      prediction has two separate round operations, first by 3
      bits (inside the various convolve functions), then by 10 bits
      (after the convolution functions).
      We can improve on this by right shifting by 3 bits inside the
      convolve functions - this is equivalent to doing a single round
      by 13 bits at the end.
      Note: In the encoder, when doing joint_motion_search(), we do
      things a bit differently: So that we can try modifying the two
      "sides" of the prediction independently, we predict each side as
      if it were a single prediction (including rounding), then blend
      these single predictions together.
      This is already an approximation to the "real" prediction, even
      in the non-jnt-comp case. So we leave that code path as-is.

      Update configuration comment about LOWBITDEPTH · 1e3da463
      Sebastien Alaiwan authored
      The comment was misleading as the codec always supports 8-bit,
      regardless of the value of CONFIG_LOWBITDEPTH.
      This flag just enables the optimized-for-8-bits pipeline,
      without changing the actual YUV output.

      Conditionally skip transform block partition search · eb8f5e87
      Jingning Han authored
      Speed up recursive transform block partition search. When a txfm
      block is selected as all zero coefficients, skip the search over
      further split partition.
      Tested with txk-sel on, this makes the speed 0 / 1 both 10 - 15%
      faster at medium - high target bit-rate range. The coding
      performance change is neutral - 0.011% better for lowres set.

      The tg_horz_boundary flag should always be 0 for the topmost

      Otherwise, we end up trying to fetch data off the top of the
      frame, which results in segfaults.
