      Refactor inv_cos_bit for speedup · 28744b5c
      Peng Bin authored
      Replace the last parameter cos_bit for all 1D inv_txfm funcions with
      a macro define, as it is actually always equal to 12. By changing it
      to const value, compiler can do further optimization.

      Implement av1_lowbd_fwd_txfm2d_8x4_sse2 · 7bd00743
      Linfeng Zhang authored
      So far the implemented av1_lowbd_fwd_#x#_sse2 provides 10% encoder
      speed up on speed 1.

      hash_based_trellis speed feature update · dea531da
      Michelle Findlay-Olynyk authored
      Add speed feature that uses hash tables to
      reuse deltas from previously found optimized
      coefficients in av1_optimize_txb. This skips some
      expensive optimize_txb calls.
      Work stopped (no current benefit):
      Current setup has worse speed (~1%), and is
      turned off by default in speed_features.c.
      Overall PSNR was ~0.1% worse. See
      go/hashBasedTrellis for feature details.
      Requires hash_me.

      Refactor pair_set_epi16 for speedup · 8b8aaffc
      Peng Bin authored
      Use _mm_set1_epi32 instead of _mm_set_epi16, less instructions produced
      by compiler. This patch also removes the duplicate define of the same
      Speed test results:
      1. Unittest for each test cases in SSE2/AV1LbdInvTxfm2d shows 60%~80%
      speedup (except those case with TX_TYPE include iidentity)
      2. A brief speed test shows that with this CL, for speed1 encoder speeds up
      ~3% and decoder speeds up ~1.8%.

      Increase seg_feature_data_max[SEG_LVL_REF_FRAME] · e4cf4fa4
      Imdad Sardharwalla authored
      Previously, segments using SEG_LVL_REF_FRAME were unable to signal the choices
      of GOLDEN = 4, BWDREF = 5, ALTREF2 = 6 and ALTREF = 7, as
      seg_feature_data_max[SEG_LVL_REF_FRAME] was set to 3. This patch increases the
      value to 7 to account for these options.

      Prevent undefined behaviour for AMVR experiment · bf2cc016
      Imdad Sardharwalla authored
      Sequences starting with intra-only frames previously resulted in undefined
      behaviour with CONFIG_AMVR == 1, as seq_force_integer_mv was only read for
      This patch makes changes as follows:
      - The syntax element force_screen_content_tools has been added to the
        SequenceHeader struct, and is read and written correspondingly
      - seq_force_integer_mv has been renamed to force_integer_mv and moved to the
        SequenceHeader struct, and is read and written correspondingly (provided that
        force_screen_content_tools != 0)
      - The conditional reading/writing of allow_screen_content_tools now happens for
        every frame after reading/writing error_resilient_mode (CONFIG_OBU == 1) or
        the sequence header (CONFIG_OBU == 0)
      - The conditional reading/writing of cur_frame_force_integer_mv now happens for
        every frame after reading/writing allow_screen_content_tools

      [NORMATIVE] Consolidate reference mv clamping · 3e225434
      Yunqing Wang authored
      Clamp_mv_ref happens in multiple places in ref_mv search, which can be
      convoluted as reported in issue 1124. This change is to consolidate
      the clamping into one place.

        0.000       0.000      0.001

      [NORMATIVE] Scale up mfmv ref step size in 64x64 block · 73190512
      Jingning Han authored
      When the coding block size has one side in length of 64 and above,
      scale up the mfmv reference search step size from 8 to 16 along
      that direction. The midres coding stats get 0.02% better. Among
      all the finished hdres points, no negative results showed up.
