      Code refactor on InterpKernel · 7186a2dd
      Zoe Liu authored
      It in essence refactors the code for both the interpolation
      filtering and the convolution. This change includes the moving
      of all the files as well as the changing of the code from vp9_
      prefix to vpx_ prefix accordingly, for underneath architectures:
      (1) x86;
      (2) arm/neon; and
      (3) mips/msa.
      The work on mips/drsp2 will be done in a separate change list.

      Keep the logic, transform size based on cyclic refresh and bsize,
      (that was conditioned on VAR_PARTITION conditions) the same
      for all speeds in non-rd mode (speeds >= 5).

      this macro was used inconsistently and only differs in behavior from
      DECLARE_ALIGNED when an alignment attribute is unavailable. this macro
      is used with calls to assembly, while generic c-code doesn't rely on it,
      so in a c-only build without an alignment attribute the code will

      encoding time increase very small, and also when allowing H/V on 16x16 blocks,
      metrics went down on a few clips which need to be further examined.

      Account for eob cost in the RTC mode decision process · 60e01c65
      Jingning Han authored
      This commit accounts for the transform block end of coefficient flag
      cost in the RTC mode decision process. This allows a more precise
      rate estimate. It also turns on the model to block sizes up to 32x32.
      The test sequences shows about 3% - 5% speed penalty for speed -6.
      The average compression performance improvement for speed -6 is
      1.58% in PSNR. The compression gains for hard clips like jimredvga,
      mmmoving, and tacomascmv at low bit-rate range are 1.8%, 2.1%, and
      3.2%, respectively.

      Refactor block_yrd function for RTC coding mode · 1470529f
      Jingning Han authored
      This commit separates Hadamard transform/quantization operations
      from rate and distortion computation in block_yrd. This allows one
      to skip SATD computation when all transform blocks are quantized
      to zero. It also uses a new block error function that skips
      repeated computation of sum of squared residuals. It reduces the
      CPU cycles spent on block error calculation in block_yrd by 40%.

      Enhance the transform skipping decision-making in non-rd mode · a0043c6d
      Yunqing Wang authored
      For large partition blocks(block_size > 32x32), the variance
      calculation is modified so that every 8x8 block's variance
      is stored during the calculation, which is used in the
      following transform skipping test. Also, the variance for
      every tx block is calculated. The skipping test checks all tx
      blocks in the partition, and sets the skip flag only if all tx
      blocks are skippable. If the skip flag of Y plane is 1, a
      quick evaluation is done on UV planes. If the current partition
      block is skippable in YUV planes, the mode search checks fewer
      inter modes and doesn't check intra modes.
      
      The rtc set borg test(at speed 6) showed that:
      Overall psnr: -0.527%; Avg psnr: -0.510%; ssim: -0.573%.
      Average single-thread speedup on rtc set was 3.5%.
      For 720p clips, more speedups were seen.

      Tuning SATD rate calculation for speed · 531468a0
      Jingning Han authored
      This commit allows the encoder to check the eob per transform
      block to decide how to compute the SATD rate cost. If the entire
      block is quantized to zero, there is no need to add anything; if
      only the DC coefficient is non-zero, add its absolute value;
      otherwise, sum over the block. This reduces the CPU cycles spent
      on vp9_satd_sse2 to one third.
