      bitstream. The second comment line was too long.

      Correct the condition for border extension · d237d483
      Yaowu Xu authored
      As reported in issue #850, the condition for border extension was not
      complete. This commit added the case when the scaling is enabled.
      This fixes issue #850.

      Remove mi_grid_* structures. · c70cea97
      hkuang authored
      mi_grid_* are arrays of pointer to pointer. They save the pointers that point
      to the MIs in cm->mi. But they are unnecessary and complicated. The original
      goal was to remove MODE_INFO_t copy. But with an extra MODE_INFO_t pointer
      inside MODE_INFO_t, same goal could be achieved.
      This commit totally removes the mi_grid_* structures. But there are still
      many dummy MODE_INFO_t inside cm->mi which are a waste of memory. Next commit
      will do on-demand MODE_INFO_t allocation in order to save these memories.

      Fix invalid memory access on 2x downscale. · 29071a41
      Alexander Voronov authored
      The issue was discovered on bitstream with 2x vertical downscale. For
      zero MVs, y_pad is set to 1 only when vertical convolution is
      required. The original code assumes that for y_step_q4 == 32 we don't
      perform vertical convolution. But vp9_setup_scale_factors_for_frame()
      sets convolve functions so that when x_step and y_step are both not
      equal to 16, convolve in both directions is performed. And convolve()
      unconditionally subtracts one stride from source pointer when calls
      convolve_horiz(). This leads to invalid memory access.

      BITSTREAM: Handle transform size and motion vectors more logically for non-420. · 7557a65d
      Alex Converse authored
      This breaks the profile 1 bitstream.
      Don't force non420 uv transform size to 1/4 y size. In the 4:2:0 case the
      chroma corresponding to a luma block is 1/4 its size. In the 4:4:4 case
      chroma and luma planes are the same size. Disallowing larger transforms
      can result in a loss of compression efficiency and is inconsistent.
      For sub-8x8 blocks only average corresponding motion vectors.
      4:2:0 and profile 0 behavior remains unchanged.

      Call set_scaled_offsets() just before scale_mv() call. · c872d2be
      Dmitry Kovalev authored
      Before mv scaling it is required to calculate x_offset_q4/y_offset_q4
      by calling set_scaled_offsets(). Now offset configuration can not be
      missed because it happens just before scale_mv().

      Use separate inter predictors for enc/dec · ba8b5e8d
      Jingning Han authored
      The decoder will construct inter predictor using lazy border extension,
      while the encoder, going with multiple runs of motion search in the rate-
      distortion optimization loop for each block, does border extension at
      frame level. This commit makes separate the inter predictors for encoder
      and decoder, respectively.

      Separate setup_scale_factor/extend_frame_borders · 86d2a9b9
      Jingning Han authored
      This commit takes out vp9_extend_frame_borders from
      The refactoring is for the preparation of the use of lazy border
      extension at decoder. This makes it necessary to handle border
      extension separately at encoder/decoder. The use of
      vp9_extend_frame_borders will be removed, when lazy border extension
      is ready.
