      Reduce transform options for ext-tx experiment · 56ab215d
      Debargha Mukherjee authored
      Reduces the transform optons for INTRA as well as INTER when
      transform size is 16x16 to not use any of the DSTs.
      Thus, a total of 10 options are used for 16x16, while 4x4
      and 8x8 still uses 17 options.
      
      derflr/hevchd actually improves a little, while hevcmr drops
      a little.
      
      About 10% speed improvement.

      hui su authored
      Remove MISC_FIXES flags except for the changes on MV precision, which
      has a 0.1% performance drop.
      
      On derflr, the impact is -0.012%.

      Flip the result of the inverse transform for FLIPADST. · 4f510809
      Geza Lore authored
      When using FLIPADST, the vp10_inv_txfm_add functions used to flip
      the destination array, add the result of the inverse transform, to it
      and then flip the destination back. This has been replaced by
      flipping the result of the inverse transform before adding it to the
      destination. Up-Down flipping is done by negating the destination
      stride, and staring from the bottom, so it should now be free.
      Left-right flipping is done with the usual SSE2 instructions in the
      optimized code.
      
      The C functions match the SSE2 functions as expected, so the C functions
      now do the flipping as well when required. Adding this cleanly required
      some refactoring of the C functions, but there is no measurable
      performance impact when ext-tx is not enabled.
      
      Encode speedup with ext-tx enabled is about 3%.

      ext-intra experiment · be3559ba
      hui su authored
      Currently there are two parts in this experiment: extra directional intra
      prediction modes and the filter intra modes migrated from the nextgen branch.
      
      Several macros are defined in "blockd.h" to provide controls of the experiment
      settings. Setting "DR_ONLY" as 1 (default is 0) means we only use directional
      modes, and skip the filter-intra modes; "EXT_INTRA_ANGLES" (default is 128)
      defines the number of different angles we want to support; setting
      "ANGLE_FAST_SEARCH" as 1 (default is 1) means we use fast sub-optimal search
      for the best prediction angle, instead of exhaustive search. The fast search
      is about 6 times faster than the exhaustive search, while preserving about
      60% of the coding gains.
      
      With extra directional prediction modes (fast search), we observe the following
      code gains (number in parentheses is for all-key-frame setting):
      derflr +0.42%  (+1.79%)
      hevclr +0.78%  (+2.19%)
      hevcmr +1.20%  (+3.49%)
      stdhd  +0.56%
      Speed-wise, about 110% slower for key frames, and 30% slower overall.
      
      The gains of filter intra modes mostly add up with the gains of directional
      modes. The overall coding gain of this experiment:
      derflr +0.94%
      hevclr +1.46%
      hevcmr +1.94%
      stdhd  +1.58%

      Fix transform tables in C implementations. · 2b39bcec
      Geza Lore authored
      These tables were out of sync with the indexing enum since the
      refactoring in commit 4f16f119 (change 303389), due to the removal
      of the ext_tx_to_txtype lookup table. This patch just puts them
      back in order.

      Incorporate flexible tx type and tx partition in RD scheme · 4b594d3d
      Jingning Han authored
      This commit hooks up the rate-distortion optimization system to
      fully exploit recursive transform block partition and multiple
      transform type. The compression performance of the two experiments
      largely adds up. For derf set, ext-tx provides additional 2.1%
      coding gains on top of the gains due to recursive transform block
      partition (0.69%).

      Refactor loop filter mask · 6727943c
      Jingning Han authored
      This commit refactors the loop filter selection process to support
      variable transform block sizes based filter mask. It disables the
      multi-thread loop filter implementation to simplify the experiments.
      The speed impact on speed 0 encoding is negligible.
