      SAD32xh and SAD64xh for AVX2 · 7045aec0
      levytamar82 authored
      All sad function that process above 32 consecutive elements are optimized
      for AVX2:
      vp9_sad64x64
      vp9_sad64x32
      vp9_sad32x64
      vp9_sad32x32
      vp9_sad32x16
      vp9_sad64x64_avg
      vp9_sad64x32_avg
      vp9_sad32x64_avg
      vp9_sad32x32_avg
      vp9_sad32x16_avg
      The functions that appeared as a hotspot is vp9_sad32x32 and vp9_sad64x64
      vp9_sad32x32 was optimized by 68% and vp9_sad64x64 was optimized by 90%
      both of them gave and overall ~2.3% user level gain

      Remove memset of every external frame buffer. · 175d9dfe
      Frank Galligan authored
      Libvpx was memseting every external frame buffer before decode. This
      was to work around a valgrind issue in our C loop filter. Most of
      the time this was not needed and we have noticed some significant
      performance loss on some platforms. Now we require the application to
      zero out the buffers if it is using external frame buffers.

      Adds high bitdepth transform functions and tests · 10783d4f
      Deb Mukherjee authored
      Adds various high bitdepth transform functions and tests.
      Much of the changes are related to using typedefs tran_low_t
      and tran_high_t for the final transform cofficients and intermediate
      stages of the transform computation respectively rather than fixed
      types int16_t/int. When vp9_highbitdepth configure flag is off,
      these map tp int16_t/int32_t, but when the flag is on, they map
      to int32_t/int64_t to make space for needed extra precision.

      vp9: correct context buffer resize check · bb4950df
      James Zern authored
      allocations within vp9_alloc_context_buffers() rely on mi_rows/mi_cols
      individually, use those to determine whether to realloc rather than
      stride and stride * rows. this fixes a crash with some fuzzed files for
      invalid accesses into last_frame_seg_map and above_context.

      James Zern authored
      proceeding using a corrupt (incompletely decoded) frame reference may
      lead to incorrect assumptions about allocation sizes leading to a crash.

      Adds config opt for highbitdepth + misc. vpx · 5acfafb1
      Deb Mukherjee authored
      Adds config parameter vp9_highbitdepth, to support highbitdepth profiles.
      Also includes most vpx level high bit-depth functions. However
      encode/decode in the highbitdepth profiles will not work until
      the rest of the code is in place.
