      Use b_width_log2_ in partition type parse · 3819f11b
      Jingning Han authored
      Replace mi_width/height_log2 with b_width/height_log2 in partition
      type parsing at bit-stream writing stage. This allows parsing
      resolution at 4x4 block level and makes the 4x4/4x8/8x4 partition
      coding consistent with other superblock types.

      Combining encode_nmv_component with encode_nmv_component_fp
      and read_nmv_component with read_nmv_component_fp. Bitstream is slightly
      changed (only the order of bits), here are the results on test sets:
      stdhd: +0.047, yt: -0.038, derf: +0.001, hd: -0.011.

      Enable recursive partition down to 4x4 · 1f26840f
      Jingning Han authored
      This commit allows the rate-distortion optimization recursion
      at encoder to go down to 4x4 block size. It deprecates the use
      of I4X4_PRED and SPLITMV syntax elements from bit-stream
      writing/reading. Will remove the unused probability models in
      the next patch.
      
      The partition type search and bit-stream are now capable of
      supporting the rectangular partition of 8x8 block, i.e., 8x4
      and 4x8. Need to revise the rate-distortion parts to get these
      two partition tested in the rd loop.

      Subsampling aware allocs and bitstream · da58436f
      John Koleszar authored
      Make framebuffer allocations according to the chroma subsamping
      factors in use. A bit is placed in the raw part of the frame header for
      each of the two subsampling factors. This will be moved in a future
      commit to make them part of the TBD feature set bits, probably only set
      on keyframes, etc.

      Extend left/above partition context to per mi(8x8) · 4a88ad89
      Jingning Han authored
      Update and buffer left/above partition information context per 8x8
      block. This allows to further enable recursive partition down to
      4x4 block size, and hence deprecating I4X4_PRED and SPLITMV.
      
      This commit also fixes a context buffer swap/restore issue in 32x32
      partition type search. This gives 0.1% performance gain for derf/yt.
      Will refactor the superblock partition type search into recursion
      form.

      Extend number of reference buffers to 8. · d7eea782
      Adrian Grange authored
      The number of reference buffers is extended to 8 and
      a reference sign-bias added for the LAST_FRAME.
      
      Whilst the number of reference buffers used by an
      individual frame remains unchanged at 3, these may
      now be selected from 8 possible buffers.

      Contextual entropy coding of partition syntax · ff2b8aa2
      Jingning Han authored
      This commit enables selecting probability models for recursive block
      partition information syntax, depending on its above/left partition
      information, as well as the current block size. These conditional
      probability models are reasonably stationary and consistent across
      frames, hence the backward adaptive approach is used to maintain and
      update the contextual models.
      
      It achieves coding performance gains (on top of enabling rectangular
      block sizes):
      derf:   0.242%
      yt:     0.391%
      hd:     0.376%
      stdhd:  0.645%

      Extension of segmentation to 8 segments. · 31ee193a
      Paul Wilkins authored
      Also some further simplification following removal
      of top node code.
      
      There is an issue in regards to the shared file vp8cx.h
      in regard to the roi_map as this interface assumes that
      there are only 4 segments. I have left the value here as
      4 for now meaning that the roi_map interface is broken
      for VP9.
      
      Note that this change would have been easier if I hadn't
      had to search for hard wire instances of the number 4
      and <= 3.
