      HBD convolution filtering (10/12 taps) SSE4.1 optimization · 8cacca73
      Yi Luo authored
      - For experiment EXT_INTERP under high bit depth.
      - Add unit test to verify bit-exact.
      - Speed performance improvement:
        On Xeon E5-2680, park_joy_1080p_12.y4m, 50 frames, encoding time
        drops from 6682503 ms to 5390270 ms.

      Refactoring in preparation for OBMC optimizations. · 007aa7dd
      Geza Lore authored
      - Use int32_t instead of int in vpx_obmc{variance,sad} functions
      - Remove weigthed_src and obmc mask strides and assume contiguous
        buffers. These inputs can always be packed as contiguous arrays.

      Remove reference frame buffer update for show_exsiting_frame · f9e38a7b
      Wei-ting Lin authored
      Originally we need to send the refresh flag and the virtual indices
      mapping for the reference frame buffer update for show_existing_frame to
      have the BWDREF_FRAME replace the LAST_FRAME.
      
      To remove sending this information, we update the the virtual indices
      of the reference frame buffer after the last_bipred_frame is encoded,
      and therefore the decoder will receive the updated reference mapping
      at the next non-show-existing frame.
      
      As a result, we can save 4 bytes per show-existing frame, and get 0.12,
      0.2, and 0.07 BDRATE improvement in lowres, derf, and midref test set
      respectively.
