      Make intra prediction pointers RTCD-based. · 8350e7fe
      Ronald S. Bultje authored
      This probably has a mildly negative impact on performance, but will
      (in future commits - or possibly merged with this one) allow SIMD
      implementations of individual intra prediction functions. We may
      perhaps want to consider having separate functions per txfm-size
      also (i.e. 4x4, 8x8, 16x16 and 32x32 intra prediction functions for
      each intra prediction mode), but I haven't played much with that
      yet.

      Don't call encode_sb() for the final of 4-split subpartitions. · a5062cc6
      Ronald S. Bultje authored
      The resulting reconstruction is never used, thus it just wastes CPU
      cycles. Reduces encode time of first 50 frames of bus (speed 0) @
      1500kbps from 2min2.0 to 2min1.2, i.e. a 0.65% overall speedup.

      Don't recalculate mv_ref costs for each block/partition. · 8fde07a3
      Ronald S. Bultje authored
      Changes cost_mv_ref() into doing a LUT into pre-calculated cost
      arrays instead. Encode time of first 50 frames of bus (speed 0)
      @ 1500kbps goes from 2min11.6 to 2min10.9, i.e. 0.5% faster overall.

      Make frame-wide filter-type decision fully RD-based. · ed995afb
      Ronald S. Bultje authored
      Overall, on all test sets, this gains about +0.2% on all metrics.
      City is a clip where this really hurts (-1.0% on all metrics), I'm
      not quite sure why yet. Maybe interesting to look into in the future.

      Implements several heuristics to prune mode search · d9b62160
      Deb Mukherjee authored
      Skips mode searches for intra and compound inter modes depending
      on the best mode so far and the reference frames. The various
      heuristics to be used are selected by bits from a flag. The
      previous direction based intra mode search pruning is also absorbed
      in this framework.
      
      Specifically the flags and their impact are:
      
      1) FLAG_SKIP_INTRA_BESTINTER (skip intra mode search for oblique
      directional modes and TM_PRED if the best so far is
      an inter mode)
      derfraw300: -0.15%, 10% speedup
      
      2) FLAG_SKIP_INTRA_DIRMISMATCH (skip D27, D63, D117 and D153
      mode search if the best so far is not one of the closest
      hor/vert/diagonal directions.
      derfraw300: -0.05%, about 9% speedup
      
      3) FLAG_SKIP_COMP_BESTINTRA (skip compound prediction mode
      search if the best so far is an intra mode)
      derfraw300: -0.06%, about 7-8% speedup
      
      4) FLAG_SKIP_COMP_REFMISMATCH (skip compound prediction search
      if the best single ref inter mode does not have the same ref
      as one of the two references being tested in the compound mode)
      derfraw300: -0.56%, about 10% speedup
