      Use new-quant lookup table in lv-map deqantization · 077e4669
      Sarah Parker authored
      When lv-map and new-quant are enabled together,
      av1_read_coeffs_txb currently does not use the new-quant
      lookup table to get the dequantized value, which causes an
      encode/decode mismatch. This patch fixes the function to
      make lv-map work with new-quant.

      Fix bustage caused by 8089315a with daala_tx. · 501acee3
      Timothy B. Terriberry authored
      The inverse transform API was changed to pass in an unpadded 32x32
      block of coefficients for transforms larger than 32x32, but the
      code path actually used for daala_tx was not modified to pad it out
      to the full size like the others were.

      Remove unused prediction modes for ext-skip · feb1ebe9
      Zoe Liu authored
      For ext-skip, if a partition block uses the new skip mode,
      NEAREST_NEARESTMV is the prediction mode. Other predictions were once
      tried out but did not show noticeable coding gains.

      Modify convolve function prototype · 940c22a2
      Yunqing Wang authored
      This patch modified convolve function prototype. The temp buffer used in
      convolve function is already available in conv_params, which doesn't need
      to be passed in. Instead, pass in the destination buffer so that the
      result can be written in the destination directly for single ref case.
      More patch will be followed.

      Imdad Sardharwalla authored
      "+ 1" has been added in a few locations to match the indices for the
      context for the CDFs and the motion vectors.
      
      Suggested fix (of removing +1s entirely) can then be implemented
      without further affecting the overall behaviour of the encoder and
      decoder.

      Enable CDEF for chroma for 4:2:2 and 4:4:0 · ab6c9c77
      Steinar Midtskogen authored
      This enables CDEF for chroma when the horizontal and vertical
      subsampling differs.  Since the direction search is only performed in
      luma, the following corrections to the direction index are done for
      chroma to correct the distortion resulting from the subsampling:
      
      4:2:2:   4:4:0:
      0 -> 7   0 -> 1
      1 -> 0   1 -> 2
      2 -> 2   2 -> 2
      3 -> 4   3 -> 2
      4 -> 5   4 -> 3
      5 -> 6   5 -> 4
      6 -> 6   6 -> 6
      7 -> 6   7 -> 0
      
      This improves the chroma PSNR BDR by about 2% for 4:2:2 content at
      cpu-used=4, low delay configuration.  4:2:0 and 4:4:4 content is
      unchanged.

      Exclude distance-weighted prediction for ext-skip · 5664419e
      Zoe Liu authored
      For ext-skip, the use of distance-weighted prediction has only shown
      a coding gain in the AMCY low delay scenario. It is hence not being
      considered and compound-average is used exlusively.

      add new experiment loopfiltering_across_tiles_ext · 7bb501d5
      Lei authored
      based on the latest discussion in the HW working group about how loop
      filter should be integrated with tiles, the following decisions have been
      made:
      1. two seperated flages should be added for
      loop_filter_across_tiles_enabled for horizontal tile boundary and
      vertical tile boundary.
      2. encoder and decoder should only check these two flags to determine
      whether loop filtering (including deblocking, CDEF and loop restoration)
      should cross tile boundaries (vertical and/or horizontal) or not
      regardless the horitontal depepdent tile flag.
      
      This change list implemented the support for two seperated
      loop_filter_across_tiles_enabled flags for vertical and horizontal tile
      boundaries. The new experiment is disabled as default before it is
      adopted.

      Conditionally drop cutting tails in lv-map coeff optimization · 8be58fad
      Jingning Han authored
      When the optimized non-zero tail is longer that 2, the likelihood
      that forcing to drop all the tail coefficients would give better
      rate-distortion optimization is much lower. This commit makes the
      encoder to check such conditions and speed up the lv-map/multi
      encoding speed.
      
      Local test clips at high target bit-rate / quality show 20% overall
      encoding speed up. The coding performance change for lowres is
      0.014%.
