      Break tile row dependencies. · 9ab9438f
      Geza Lore authored
      When not using ext-tile, there were still dependencies between tile
      rows due to various tools (eg intra predictors) relying on the above
      row or above mode info, which can be in the above tile. This is now
      broken (the same way as it was when ext-tile is enabled) by fixing
      the appropriate predicates.

      Rename MI_BLOCK_SIZE and MI_MASK macros. · 511da8cb
      Geza Lore authored
      Rename MI_BLOCK_SIZE.* -> MAX_MIB_SIZE.* (MIB is for MI Block).
      Rename MI_MASK.* -> MAX_MIB_MASK.*
      
      There are no functional changes.
      
      This is in preparation for coding the superblock size at the frame
      level, which will require some of these constants to become variables.
      The new names better reflect future semantics, and hence make the code
      clearer.

      Geza Lore authored
      If --enable-ext-partition is used at build time, the superblock size
      (sometimes also referred to as coding unit (CU) size) is extended to
      128x128 pixels.

      Adding new compound modes to EXT_INTER experiment · 968bbc7b
      Yue Chen authored
      Combinations of different mv modes for two reference frames
      are allowed in compound inter modes. 9 options are enabled,
      including NEAREST_NEARESTMV, NEAREST_NEARMV, NEAR_NEARESTMV,
      NEAREST_NEWMV, NEW_NEARESTMV, NEAR_NEWMV, NEW_NEARMV, ZERO_ZEROMV,
      and NEW_NEWMV.
      This experiment is mostly deported from the nextgen branch.
      It is made compatible with other experiments

      EXT_INTER experiment · 1ac85879
      Yue Chen authored
      NEW2MV is enabled, representing a new motion vector predicted from
      NEARMV. It is mostly ported from nextgen, where it was named
      NEW_INTER.
      A few fixes are done for sub8x8 RDO to correct some misused
      mv references in the original patch.
      A 'bug-fix' for encoding complexity is done, reducing the additional
      encoding time from 50% to 20%. In sub8x8 case, the old patch
      did motion search for every interpolation filter (vp9 only
      searches once). This fix also slightly improves the coding gain.
      This experiment has been made compatible with REF_MV and EXT_REFS.
      
      Coding gain (derflr/hevcmr/hevchd): 0.267%/0.542%/0.257%

      This commit allows the codec to add motion vector pairs into
      the candidate list. It further improves the compression performance
      by 0.1% across derf, hevcmr, stdhd, and hevchr sets without adding

      Analyze motion field to produce reference motion vectors · 254d3e17
      Jingning Han authored
      This commit allows the codec to analyze the motion field in the
      avaiable above and left neighboring area to produce a set of
      reference motion vectors for each reference frame. These reference
      motion vectors are ranked according to the likelihood that it will
      be picked.

      vp10: clip MVs before adding to find_ref_mvs() list. · 293e20df
      Ronald S. Bultje authored
      This causes the output of find_ref_mvs() to always be unique or zero.
      A nice side-effect of this is that it also causes the output of
      find_ref_mvs_sub8x8() to be unique-or-zero, and it will not ignore
      available candidate MVs under certain conditions.
      
      See issue 1012.

      vp10: allow MV refs to point outside visible image. · dea99899
      Ronald S. Bultje authored
      In VP9, the ref MV had to point to a block that itself fully resided
      within the visible image, i.e. all borders of the image had to be
      within the visible borders of the coded frame. This is somewhat
      illogical, and had obscure side effects, e.g. clamping of fairly
      reasonable motion vectors such as 0,0 were clipped to negative values
      if the block was overhanging on frame edges (such as the last rows
      on 1080p content), which makes no sense whatsoever.
      
      Instead, relax clamping constraints such that the ref MVs are allowed
      to point to blocks exactly outside the visible edges in both Y as well
      as UV planes, including the 8tap filter edges (that's why the offset is
      8 pixels + block size).
      
      See issue 1037.

      vp10: remove double MV value check. · 43be86db
      Ronald S. Bultje authored
      This has virtually no effect on coding efficiency, but it is more
      logical from a theoretical perspective (since it makes no sense to
      me that you would exclude a MV from a list just because it's sign-
      inversed value is identical to a value already in a list), and it
      also makes the code simpler (it removes a duplicate value check in
      cases where signbias is equal between the two MVs being compared).
      
      See issue 662.
