      Add stage range configurations for fwd transforms · b31ff9b2
      Debargha Mukherjee authored
      Only the row transforms are needed since the forward transform
      is designed to do col first and then row. So the col transform
      can reuse the same configuration as the col transform of a
      square block of the same size.

      [CFL] Code cleaning and Fix for TXK_SEL · 439ba638
      Luc Trudeau authored
      Small code cleaning and partially resolves issue 1171. I can't confirm
      that it's a complete fix because the code asserts further a long
      
      aomenc: ../av1/common/blockd.h:1064: av1_get_tx_type:
        Assertion `tx_type < TX_TYPES' failed.

      Use new-quant lookup table in lv-map optimization · 3d75209a
      Sarah Parker authored
      Currently, optimize_txb does not use the new-quant
      lookup table when it updates the coefficients. This
      fixes the function to avoid a mismatch.
      
      With this patch, new-quant adds 0.28% gains on top of
      lv-map-multi on 40 frames of lowres.

      Make chroma loopfiltering tx_sizes consistent · 8aec7f30
      Debargha Mukherjee authored
      Removes existing inconsistencies between chroma tx_sizes
      used for chroma loopfiltering.
      Includes various refactoring to remove the uv_txsize_lookup

      Option to disable small tx size for intra chroma · 80592c72
      Debargha Mukherjee authored
      This is essentially an implementation of Mozilla's big_chorma_tx
      proposal, and CFL is already using this.
      
      The option is turned on by default.
      Also includes some associated refactoring.

      Don't force inlining for msvc targets. · 1b63eb33
      Ralph Giles authored
      INLINE is defined as __forceinline for vs* configs, but is the
      normal, compiler-discretion inline for gcc/clang configs. This
      makes many functions very large when building for windows targets,
      much larger than they are elsewhere.
      
      Use '__inline' as a consistent definition to get consistent function
      sizes. Thanks to David Major for the diagnosis.

      Take out drl index control from opt-ref-mv · b4fc74da
      Jingning Han authored
      Removing the drl dependency on the candidate list length appears
      to incur more than 0.3% compression performance loss. Hence remove
      this option from opt-ref-mv to allow better latency vs compression
      performance trade off.

      Add the syntax/decoder support for fwd-kf · a7c1b196
      Zoe Liu authored
      Forward-coded KEY_FRAME, served as a backward reference frame, is
      coded as intra-only. The show_existing_frame to show the buffered
      forward KEY_FRAME needs to reset the frame context as well as reset
      the reference frame buffer.
      
      One binary symbol, namely reset_decoder_state, is added to the frame
      header. Whenever a frame is a show_existing_frame, it reads out this
      binary symbol value from the bitstream. When this binary symbol is
      1, it indicates that the existing frame to show shall be an intra
      coded frame and will serve as a KEY_FRAME. The frame context is set
      to default and the reference buffer is updated the same way as a
      normal KEY_FRAME.
