      Record total rate cost in trellis · 82775f61
      Cheng Chen authored
      Record total rate cost when computing trellis optimization.
      Reduce redundant rate computation in later stages.
      
      Speed impact: ~6% speed up
      Coding performance should not be affected.

      Added SSE4.1 and AVX2 implementations of FAST SGR. · 9d234571
      Imdad Sardharwalla authored
      The self-guided filter speed tests show that:
      - The SSE4.1 implementation of FAST SGR is ~35% faster than the corresponding
        implementation of SGR;
      - The AVX2 implementation of FAST SGR is ~28% faster than the corresponding
        implementation of SGR.

      Add a config flag/code for fast sgr computation · ed5e9673
      Debargha Mukherjee authored
      Adds an experiment for fast sgr computation where for the r=2
      filter, computation of the A, B stats are computed for every
      other row and averaged in between.
      The motivation is to improve software performance with hopefully
      minimal loss.

      [loop-restoration, bugfix] Restrict sampling of deblocked pixels · dff901ff
      David Barker authored
      There is a special case with certain frame heights, where we
      end up with a loop restoration stripe which ends 1px above the
      crop border.
      
      Previously this case was handled in quite an ugly way, which also
      disagrees with the spec (+ isn't great for hardware). This patch
      changes things to match the spec.
      
      Specifically, the old method was to sometimes upscale one extra
      row of deblocked pixels so that we could always have a 2px
      "below" border for each processing stripe. The new method is to
      only use rows inside the crop border, and to duplicate them if
      necessary.

      Simplify cos_bit setting in txfm · d4327bce

      Move cos_bit from txfm 1d cfg to 2d cfg
      Each txfm stage only uses one cos_bit
      
      This is a lossless change and it speeds up encoder by 2%

      Skip RD search over lst 2/3 frame for non-nearest neighbor mvs · 8db5f17b
      Jingning Han authored
      Skip the rate distortion search over last 2/3 reference frames for
      the reference motion vectors derived from non-nearest neighbors.
      The overall coding performance change is in the noise range - 0.05%
      better. Speed up the encoding process by 20%.

      Use split and horz/vert to predict horzA/B/vertA/B · 6001fb05
      Zoe Liu authored
      In rd_pick_partition(), the first one or two blocks for the partition
      types HORZ_A, HORZ_B, VERT_A, and VERT_B may be already evaluated,
      during the evaluation of SPLIT, HORZ, and VERT. This patch saves the
      RD pick mode results and tries to reuse them to remove the duplicate
      RD mode evaluation operations.
      
      This patch should not incur any coding performance loss.
      
      Testing on a few lowres frames: when CFL is off, this patch obtains
      >10% encoder speedup.

      This commit replaces hard coded FRAME_ID_NUMBERS_PRESENT_FLAG with
      error_resilient_mode, which properly reflects the intention of the
      experiment, i.e. "signal the complete state of the reference buffer
      explicitly for each frame" to deal with possible frame losses.

      add scalability experiment · 2eeadab1
      Soo-Chul Han authored
      configure:  --enable-experimental --enable-scalability
      
      New applications:  scalable_encoder, scalable_decoder
      
      scalable_encoder:
        * Encodes inputs as 2-layer (same size) stream
        * Encodes as obu file (OBU_NO_IVF must be enabled)
        * Base layer encoded in IPPPP where P's reference
          only the previous (in time) base layer
        * Enhancement layer encoded using its base layer as
          sole reference frame
        * Base layer encoded with fixed high QP
        * Enhancement layer encoded with fixed low QP
      
      scalable_decoder:
        * Able to decode scalable stream generated by
          scalable_encoder
        * Able to decode any single-layer stream encoded
          by aomenc
        * Outputs base layer as out_lyr0.yuv, and enhancement
          layer (if they exist) as out_lyrN.yuv (N = 1, 2, 3, ..)
        * Able to decode N layers (more than 2)

      Added a test for monochrome encoding. · 26ac0478
      Imdad Sardharwalla authored
      The test encodes 5 frames of a video using the --monochrome flag and
      verifies that the decoded frames satisfy:
      
      - each frame's monochrome flag is set to 1
      - each frame's U and V planes are set to a constant, and this constant
        is the same for all decoded frames
      - the initial frame's Y PSNR value is 'high enough'
      - the Y PSNR values remain fairly constant across all of the frames
