      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.

      vp10: fix 4:2:2 chroma MVs for 8x4/4x4 blocks. · ed29c2f9
      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.

      Add support for color-range. · eeb5ef0a
      Ronald S. Bultje authored
      In decoder, export (eventually) into vpx_image_t.range field. In
      encoder, use oxcf->color_range to set it (same way as for
      color_space).
      
      See issue 1059.

      vp10: fix entropy counts for the hp bit. · 1e9e9ce2
      Ronald S. Bultje authored
      The counts didn't take usehp into account, which means that if the
      scope of the refmv is too large for the hp bit to be coded, the value
      (always 1) is still included in the stats. Therefore, the final
      counts will not reflect the entropy of the coded bits, but rather the
      entropy of the combination of coded bits and the implied value (which
      is always 1). Fix that by only including counts if the hp bit is
      actually coded.
      
      See issue 1060.

      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.

      This makes it easier to add new transform types and scan orders
      to VP10 in the future.
