      Find warped reference MV · 97d6a37e
      Yunqing Wang authored
      While finding the reference MV for a block, if one neighbouring block's
      motion mode is warped motion mode, instead of directly adding that
      block's MV to the candidate MV list, we use that neighbouring block's
      warped motion parameters to compute a MV for the center point of the
      current block, and then add that MV to the candidate MV list.
      
      Borg test result:
                   avg_psnr ovr_psnr ssim
      cam_lowres:  -0.507   -0.514  -0.685
      lowres:      -0.114   -0.122  -0.180
      
      The change is added under ext_warped_motion config flag.

      Make horzonly-frame-superres a config flag. · 3d8bcb2a
      Urvang Joshi authored
      This allows it to be enabled/disabled during configure/cmake and also
      allows us to specify dependencies.
      
      If 0: superres scaling happens for both width and height.
      If 1: superres scaling happens ONLY for width.

      lgt-from-pred: transforms based on prediction · 432012f6
      Lester Lu authored
      In this experiment, sharp image discontinuity in the predicted
      block is detected. Based on this discontinuity, we choose
      particular LGTs as row and column transforms.
      
      Bitstream syntax, entropy coding, and RD search for LGT are added.
      One binary symbol is used to signal whether LGT is used. This
      experiment can work independently with the lgt experiment.
      
      lowres: -0.414% for key frames, -0.151% overall
      midres: -0.413% for key frames, -0.161% overall

      Add experiment ext_skip · a3c5b9da
      Zoe Liu authored
      This coding tool is to introduce a new prediction mode for the
      bi-predictive frames that have a forward referernce within 2 frames
      away (distance denoted as 'fwd_delta'), and a backward reference,
      within (3-fwd_delta) frames away.
      
      If this prediction mode, namely 'ext_skip' is set, it will be coded
      using compound prediction with the most recent forward and backward
      reference frames as its reference pair, NEARESTMV as its motion mode,
      and the skip flag is set for the residue.

      Add experiment of frame_sign_bias · 51f1b7df
      Zoe Liu authored
      This coding tool is dependent on the tool of frame_marker. This tool
      derives the frame sign bias directly from the frame offset. No sign
      bias signaling is needed.

      Modify storing and using of the temporal frame MVs · d1d511f3
      Yunqing Wang authored
      Add an experiment "tmp", which includes:
      1. Always use larger block size while storing frame MVs and make
      it consistent for CB4X4 or non-CB4X4 cases. Namely, use 8x8 for
      4x4 mi size and 16x16 for 8x8 mi size.
      2. Allocate smaller buffer for frame MVs and save memory usage.
      3. Use nearby 8x8 or 16x16 location's previous frame MVs, and make
      the logic simple.
      4. Reduce the number of copying for frame MVs, that is very costly
      in decoder.
      
      Baseline decoder got 5+% speedup. Borg test on lowres set showed a
      +0.009% PSNR difference before/after the patch.

      Sync CMake treatment of aom{dec,enc} with configure. · 9cc0cfed
      Tom Finegan authored
      Disable creation of the aomdec and aomenc targets
      when examples are disabled. This requires some changes
      to how/when utility libs are built. The common, decoder,
      and encoder app utils are now only built when one of
      CONFIG_UNIT_TESTS, ENABLE_EXAMPLES, or ENABLE_TOOLS is
      enabled.

      Relocate CMake experiment conflict resolution. · e2e441df
      Tom Finegan authored
      Move it to build/cmake/aom_experiment_deps.cmake within
      the macro fix_experiment_deps() to reduce noise in
      aom_configure.cmake.
      
      Note: This patch also resolves a conflict between the
      CMake and configure build configs: rect_tx and var_tx
      conflicts with daala_dctX have been resolved. The two
      experiments are no longer disabled when daala_dctX is
      enabled.
