      Correct cmake intrinsic flag translation. · 0b3c9052
      Tom Finegan authored
      MSVC only. Use the AVX/AVX2 flags only for AVX and AVX2. Ignore
      the SSE flags since they're not needed with MSVC.

      Speed up global motion determination · 15338d5f
      David Barker authored
      When global-motion is enabled, a considerable amount
      of encoder time is spent in the functions in corner_match.c.
      This patch optimizes those functions to be 3.5-4x as fast,
      leading to an end-to-end encoder speed improvement
      (on 20 frames of tempete_cif.y4m) of:
      
       200kbps: ~26% faster
       800kbps: ~19% faster
      2800kbps: ~12% faster

      Add flag for RAWBITS to use raw bits with DAALA_EC. · 24f1a904
      Nathan E. Egge authored
      The use of raw bits is now disabled by default and can be turned on with:
       ./configure --enable-experimental --enable-rawbits
      This commit has a negligible impact on rate.

      Fix segfault with loop-restoration on x86. · befcc425
      David Barker authored
      The WienerInfo struct requires a 16-byte alignment on x86,
      since it contains filter coefficients which are loaded using
      SSE aligned load instructions. But on 32-bit x86, the default
      alignment of aom_malloc/aom_realloc is only 8 bytes, leading
      to occasional segfaults.
      
      To fix this, rather than using aom_realloc to resize WienerInfo
      structures, we always free and re-allocate them using aom_memalign

      Add a new experiment of REF_ADAPT · b05e5d10
      Zoe Liu authored
      Noticed that some ALTREF_FRAMEs could have used compound modes for its
      prediction but have been labeled as SINGLE_REFERENCE mode in the frame
      header. This experiment is to remove the COMPOUND_REFERENCE mode from
      the frame-level reference mode choices and only leave SINGLE_REFERENCE
      and REFERENCE_MODE_SELECT the two choices in the frame header.
      
      When turning on both ext-refs and ref-adapt, compared against ext-refs
      itself, a small gain is achieved. In PSNR, the bitrate saving gains are
      as follows:
      
      lowres: Avg -0.120%; BDRate -0.128%
      midres: Avg -0.155%; BDRate -0.128%
