      Removing inv_txm4x4_1_add and inv_txm4x4_add function pointers. · c983c966
      Dmitry Kovalev authored
      We already have itxm_add member in MACROBLOCKD structure. Both
      inv_txm4x4_1_add and inv_txm4x4_add are just its special cases for
      different eob values. But eob logic is already implemented in
      vp9_iwht4x4_add and vp9_idct4x4_add (that's why also removing
      inverse_transform_b_4x4_add).

      Moving all idct/iht functions in one place. · be7eec79
      Dmitry Kovalev authored
      Moving functions from vp9_idct_blk to vp9_idct because these functions are
      used from both encoder and decoder. Removing duplicated code from
      vp9_encodemb.c and reusing existing functions.

      Enable per transformed block zero coeffs forcing · a517343c
      Jingning Han authored
      This commit enables forcing all coefficients zero per transformed
      block, when its rate-distortion cost is lower than regular coeff
      quantization.
      
      The overall performance improvement (including its parent patch on
      calculating rd cost per transformed block) at speed 1:
      derf:  0.298%
      yt:    0.452%
      hd:    0.741%
      stdhd: 0.006%

      New mode_info_context storage -- undo revert · ac6093d1
      Scott LaVarnway authored
      mode_info_context was stored as a grid of MODE_INFO structs.
      The grid now constists of pointers to MODE_INFO structs.  The
      MODE_INFO structs are now stored as a stream (decoder only),
      eliminating unnecessary copies and is a little more cache
      friendly.

      Fix overflow issue in 16x16 quantization SSSE3 · 09bc942b
      Jingning Han authored
      The 16x16 transform unit test suggested that the peak coefficient
      value can reach 32639. This could cause potential overflow issue
      in the SSSE3 implmentation of 16x16 block quantization. This commit
      fixes this issue by replacing addition with saturated addition.

      For the test clips used, the decoder performance improved
      by ~4.3% (1080p) and ~9.7% (720p).
      
      Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p)
      and 5.9% (720p).

      Using plane_bsize instead of bsize. · 2e3478a5
      Dmitry Kovalev authored
      This change set is intermediate. The next one will remove all repetitive
      plane_bsize calculations, because it will be passed as argument to
      foreach_transformed_block_visitor.

      Use low precision 32x32fdct for encodemb in speed1 · debb9c68
      Jingning Han authored
      The low precision 32x32 fdct has all the intermediate steps within
      16-bit depth, hence allowing faster SSE2 implementation, at the
      expense of larger round-trip error. It was used in the rate-distortion
      optimization search loop only.
      
      Using the low precision version, in replace of the high precision one,
      affects the compression performance by about 0.7% (derf, stdhd) at
      speed 0. For speed 1, it makes derf set down by only 0.017%.
