      Separate quantizaton for U and V plane · be42dc72
      Yaowu Xu authored
      This commit adds code to support separate regular quantization for U
      and V. They currently always use same quantization parameter, hence
      this commit does not change bitstream at all.

      JNT_COMP: turn off for one_sided_compound · 060e192b
      Cheng Chen authored
      One_sided_compound is less likely to provide gains for jnt_comp.
      Stop jnt_comp search when one_sided_compound is true. It saves coding
      time as well as bit overhead.

      Add the q_segmentation experiment · f624dd5a
      Rostislav Pehlivanov authored
      This experiment implements low-cost delta q signalling on a per-block basis
      for all non-inter frame types, which would allow for more efficient AQ
      which bases its decisions on temporal information.
      
      Based on an Intel proposal from March.

      Separate quantizers used for quantization from RDO · 125c0fca
      Monty Montgomery authored
      Generalize quantizer setup so that quantization and TX can use
      different coefficient shifts/scalings without inpacting RDO lambda
      generation.
      
      This patch is documentaiton + a minor refactor setting up later
      work; it causes no functional change.

      Revert "Turn on the max_tile experiment" · 81d458b2
      Yaowu Xu authored
      This reverts commit ab8bb8b8.
      
      The reverted breaks many nightly run tests, reverting this temporarily
      to allow nightly tests to detect other failures. Once the issues are
      fixed, we can reenable the change in the reverted commit.

      Turn on the max_tile experiment · ab8bb8b8
      Dominic Symes authored
      max_tile was provisionally adopted at the working group meeting 2017-Oct-10
      
      This patch also enables support for 64x64 and 128x128 superblock size for max tile
      (rather than assuming 128). There is also one fix for max_tile in combination of
      loop restoration where the width/height was in the wrong units for max-tile specific code.

      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.

      Correct striped-loop-restoration with multiple tile rows · dee00eb0
      Rupert Swarbrick authored
      Before this patch, striped loop restoration didn't restart correctly
      on each tile row. Now, the loop restoration stripes start at the top
      of a tile row in the same way as if it were the top of the entire
      frame.

      Add decoder support to ext_skip · f704a1c8
      Zoe Liu authored
      At the frame header level, add the checking on whether an inter-coded
      frame allows the use of 'skip_mode'. At the block level, add the
      decoding of 'skip_mode' for all the blocks if 'skip_mode' is allowed
      for the current frame. If 'skip_mode' is set, no further bit needs to
      read out, and the block is set as:
      - Inter-coded in compound mode;
      - With the nearest forward and backward reference frames;
      - In NEAREST_NEARESTMV mode;
      - In SIMPLE_TRANSLATION motion mode;
      - In COMPOUND_AVERAGE compound type; and
      - Skip set for residual.

      Speed up inter frame rate-distortion optimization · cf842ad2
      Jingning Han authored
      The frame marker system supports one to map the reference frame
      index into the natural order. It allows direct checking on the
      efficacy of the reference frames given their relative locations
      with respect to the current coding frame.
      
      This commit uses such property to filter out reference frames
      less likely to contribute coding gains from the rate-distortion
      optimization process. For example, it takes out the check on
      last2 / 3 frames, when their actual location is further away
      from the golden frame.
      
      The AWCY results show 0.6% performance regression. The encoding
      speed gets doubled.
      
      To use the speed up, one needs to turn on frame-marker experiment
      before we turn it on by default, and enable selective_ref_frame
      entry in the speed feature.

      Remove RestorationInternal from AV1_COMMON · f88bc049
      Rupert Swarbrick authored
      The bits needed by striped loop restoration are now in
      RestorationInfo (which also gets rid of a rather ugly extra
      index).
      
      The scratch buffer that's used for self-guided restoration has been
      moved up to its own variable (rst_tmpbuf).
      
      All the rest of the fields are now safely hidden inside restoration.c
      
      This patch also does a big cleanup of the initialisation code in
      loop_restoration_rows: it doesn't need to be as repetitive now that
      the fields of YV12_BUFFER_CONFIG can be accessed by plane index.
