      Adjustments to key frame sizing. · 21ff7bdc
      Paul Wilkins authored
      Adjustments take heavier account of the frame near a kf
      in deciding boost and limit the total number that can contribute.
      Also adjusted the minq calculations such that in most cases we
      generate a smaller key frame.
      Modified the code that accounts for how static the sequence is and
      added some adjustment based on image size. This is still very
      crude but smaller images tend to behave better with a larger
      delta between KF Q and other frames than larger image formats.
      Changes give sizable gains in overall PSNR  on all the test sets but the
      biggest gains (~3%) were on the std-hd set.
      The gains were smaller for SSIM but still significant.
      Average PSNR results are mixed because this metric can very easily
      be altered by having a very good / lossless coding of one or two frames.
      Some of the YT and YT-HD clips in particular have blank lead ins and
      allowing lossless coding of these appears to make a big difference to
      average PSNR but it reality does not help much at all.

      Removing rounding from UV MV calculation · 2987fa1d
      John Koleszar authored
      Consider the previous behavior for the MV 1 3/8 (11/8 pel). In the
      existing code, the fractional part of the MV is considered separately,
      and rounded is applied, giving a result of 6/8. Rounding is not required
      in this case, as we're increasing the precision from a q3 to a q4, and
      the correct value 11/16 can be represented exactly.
      
      Slight gain observed (+.033 average on derf)

      make buid_inter_predictors block size agnostic (luma) · 4924934d
      John Koleszar authored
      This commit converts the luma versions of vp9_build_inter_predictors_sb
      to use a common function. Update the convolution functions to support
      block sizes larger than 16x16, and add a foreach_predicted_block walker.
      
      Next step will be to calculate the UV motion vector and implement SBUV,
      then fold in vp9_build_inter16x16_predictors_mb and SPLITMV.
      
      At the 16x16, 32x32, and 64x64 levels implemented in this commit, each
      plane is predicted with only a single call to vp9_build_inter_predictor.
      This is not yet called for SPLITMV. If the notion of SPLITMV/I8X8/I4X4
      goes away, then the prediction block walker can go away, since we'll
      always predict the whole bsize in a single step. Implemented using a
      block walker at this stage for SPLITMV, as a 4x4 "prediction block size"
      within the BLOCK_SIZE_MB16X16 macroblock. It would also support other
      rectangular sizes too, if the blocks smaller than 16x16 remain
      implemented as a SPLITMV-like thing. Just using 4x4 for now.
      
      There's also a potential to combine with the foreach_transformed_block
      walker if the logic for calculating the size of the subsampled
      transform is made more straightforward, perhaps as a consequence of
      supporing smaller macroblocks than 16x16. Will watch what happens there.

      Recursive partition syntax coding · 90a91cc6
      Jingning Han authored
      Enable recursive partition information coding from SB64X64 down to
      MB16X16. The bit-stream syntax is now supporting rectangular block
      sizes. It starts from SB64X64 and recursively describes the partition
      type of the current block. If the partition type is PARTITION_NONE,
      the block is coded as a single unit; if it is PARTITION_HORZ or
      PARTITION_VERT, the block is segmented into two independently coded
      rectangular units, with no further partition needed; otherwise, the
      block is segmented into 4 square blocks. i.e., PARTITION_SPLIT case,
      each can be potentially further partitioned.
      
      Forward adaptive probability modeling is used for the partition
      information coding, conditioned on the current block size.

      Combine superblock inter predictors into a unified function that
      allows configurable block width and height. The inter predictions
      of block sizes smaller than 16x16 are handled differently. To be
      continued on merging them later.

      Move prediction hit counting to update_state(). · 79fd8c29
      Ronald S. Bultje authored
      The probabilities derived from these statistics are used in bitstream
      writing; therefore, we should only do this when we actually decide to
      use macroblock coding (over superblock coding). Derf gains +0.15%.
