      Make mv storage independent of ref frame index · 707f8321
      Jingning Han authored
      The motion vector storage location in the reference frame is set
      to be dependent on the relative frame position, instead of the
      reference frame index.

      of the sequence header.
      Monochrome is now coded as a type of colorspace.

      Change q_segmentation to spatial_segmentation · 938710cb
      Rostislav Pehlivanov authored
      Adds spatial prediction to standard segmentation instead of a separate
      segmentation feature.
      When using temporal prediction skipped blocks are flagged as mispredicted.

      max-tile: Fix issues discovered when testing max-tile · 917d6c06
      Dominic Symes authored
      max-tile remains off by default until more testing is performed but I would
      like to check in the fixes that are known so far to prevent this patch getting too big
      
      max_tile was provisionally adopted at the working group meeting 2017-Oct-10
      
      This patch fixes the following issues:
      - max_tile is fixed to suport superblock size 64x64 as well as 128x128 (ext_partition support)
      - max_tile is fixed in combination with loop_restoration
      - max_tile is fixed in combination with ext_tile (Bug: 1013)
      - max_tile is fixed in combination with lv_map and 64x64 subperblock (lv_map memory allocation
        fixed for 64x64 superblock)
      - max_tile reports the size of the first tile for inspection.c used by the analyzer

      Change CDEF block skip condition and move signalling · 6c24b029
      Steinar Midtskogen authored
      Previously CDEF was implicitly disabled for a filter block if all its
      sub-blocks were skip, and no bits for that block was signalled.  That
      required the CDEF signal to be transmitted at the end of the block,
      and it was not possible to begin the filtering of the block before
      that.
      
      This patch moves the signalling to just after the first zero skip bit
      within a 64x64, 128x64, 64x128 or 128x128 block.  If sub-blocks are
      skip, then no CDEF bits will be signalled, as before.  Also, the skip
      condition flag has been removed so it's always known at the skip flag
      whether a coding block is to be filtered or not.

      [CFL] CfL Initialization Simplification · 1e84af52
      Luc Trudeau authored
      The CfL context is now stored inside MACROBLOCKD instead of
      MACROBLOCKD only storing a pointer to the CfL context.
      The intent is to avoid race conditions as MACROBLOCKD is stored
      inside ThreadData. This change also simplifies CfL Initialization.

      Disallow 4:1/1:4 partitions for BLOCK_128x128 · eb123933
      Rupert Swarbrick authored
      The change can be temporarily reverted by setting ALLOW_128X32_BLOCKS
      to 1 (for easy "is this better?" testing: we'll get rid of the option
      once it's clear what we're doing).
      
      Since this means we have to modify the "num_partition_types"
      calculation in functions like read_partition, we move it into a helper
      function called partition_cdf_length(). Doing this makes the bodies of
      read_partition and write_partition somewhat simpler than they were.

      Add motion selection to ext_skip · f40a9577
      Zoe Liu authored
      A new block mode, referred to as skip_mode is added. If a block is
      coded as skip_mode, it will be inter-coded, with its references and
      motion vectors derived from its neighboring blocks with zero-residue.
      Otherwise, the block can be coded in the current intra or inter mode.
      
      The computational load on skip_mode evaluation at the encoder should
      be kept minimum. No transform size / type evaluations are needed.

      Plumb in a "monochrome" flag · e0b15997
      Rupert Swarbrick authored
      This bit appears in the sequence header. At the moment, it does
      nothing, but it will mean that we don't encode (or read) chroma
      planes.
      
      This patch adds the flag to the sequence header, and also adds an
      encoder option (--monochrome) which enables it. At the moment, this
      doesn't do anything except cause the bit to be set correctly in the
      header.

      Separate ref frame mvs control from prev_frame_mvs · e17ebe92
      Jingning Han authored
      The control of using reference frame motion vector is a separate
      factor from the existence of previous frame motion vectors. This
      commit decouples these two, such that the encoder can control the
      use of reference motion vector. When it is used, one can further
      identify if the previous frame exists or not, then to decide if
      need to force use_prev_frame_mvs to be zero.
      
      This solves the issue where the previous frame mvs is set to be
      0 and it accidentally shuts off the access to all other existing
      referece frames mvs in the mfmv system. It brings back the coding
      performance gains to normal.
