      vp10: do sub8x8 block reconstruction in full subblocks. · 50f94427
      Ronald S. Bultje authored
      This means that we don't reconstruct in 4x4 dimensions, but in
      blocksize dimensions, e.g. 4x8 or 8x4. This may in some cases lead
      to performance improvements. Also, if we decide to re-introduce
      scalable coding support, this would fix the fact that you need to
      re-scale the MV halfway the block in sub8x8 non-4x4 blocks.
      
      See issue 1013.

      Ronald S. Bultje authored
      In vp9, the bottom MV would be the average of the topright and
      bottomleft luma MV (instead of the bottomleft/bottomright luma MV).
      
      See issue 993.

      vp10: code sign bit before absolute value in non-arithcoded header. · a3df343c
      Ronald S. Bultje authored
      For reading, this makes the operation branchless, although it still
      requires two shifts. For writing, this makes the operation as fast
      as writing an unsigned value, branchlessly. This is also how other
      codecs typically code signed, non-arithcoded bitstream elements.
      
      See issue 1039.

      vp10: don't reset contextual skip flag if block has no coefficients. · a5d930e4
      Ronald S. Bultje authored
      The implicitly changed value would be used for contextualizing future
      skip flags of neighbour blocks (bottom/right), which is certainly not
      what was intended. The original code stems from vp8, and was useful
      in cases where coding of the skip flag was disabled. In vp9, the skip
      flag is always coded. The result of this change is that for bitstream
      parsing purposes, decoding of the skip flag becomes independent of
      decoding of block coefficients.
      
      See issue 1014.

      color_space).

      Make update_map/temporal_update fields implicit for keyframes. · d88cee37
      Ronald S. Bultje authored
      These frame types cannot make bitstream parsing depend on previous
      frames, so the hypothetical combinations of e.g. keyframe=1 and
      update_map=0 or keyframe=1 and temporal_update=1 are non-sensical.
      Therefore, make it impossible to code such combinations in the vp10
      bitstream header.
      
      See issue 1044.

      Unify coding order of MC filters between blocks and frame header. · ecd34e64
      Ronald S. Bultje authored
      In VP9, the order for frame header was: [0] smooth, [1] regular, [2]
      sharp, [3] bilinear. Per-block, the order was [0] regular, [1] smooth
      and [2] sharp. For VP10, swap smooth/regular in the frame header so
      that the block ordering and frame header ordering are interchangeable.
      
      See issue #1046.

      Code refactor on InterpKernel · 7186a2dd
      Zoe Liu authored
      It in essence refactors the code for both the interpolation
      filtering and the convolution. This change includes the moving
      of all the files as well as the changing of the code from vp9_
      prefix to vpx_ prefix accordingly, for underneath architectures:
      (1) x86;
      (2) arm/neon; and
      (3) mips/msa.
      The work on mips/drsp2 will be done in a separate change list.

      Correctly report "Unsupported bitstream profile" · 7c0c62df
      Yaowu Xu authored
      For vp9 decoder build without profile 2 and profile 3 support, this
      commit changes to report error "Unsupported bitstream profile" for
      input streams in profile 2 or 3, rather than other misleading error
      information.
      
      In addition, one of the invalid files in unit tests is actually coded
      profile 2, this commit makes it tested only when the decoder is built
      with vp9-highbitdepth.
      
      This fixes issue #1028.

      Flaten the intra block decoding process. It removes the legacy
      foreach_transformed_block use in the decoder. This saves cycles
