      change to make use of more trellis quantization · 2e53e9e5
      Yaowu Xu authored
      when a subsequent frame is encoded as an alt reference frame, it is
      unlikely that any mb in current frame will be used as reference for
      future frames, so we can enable quantization optimization even when
      the RD constant is slightly rate-biased. The change has an overall
      benefit between 0.1% to 0.2% bit savings on the test sets based on
      vpxssim scores.

      Remove INTRARDOPT #define and intra_rd_opt option. · dd08db93
      Timothy B. Terriberry authored
      This is just eliminating some cruft.
      Although a number of variables are declared only when INTRARDOPT
       is defined, they are used elsewhere without that protection, and
       no longer just for intra RDO.
      The intra_rd_opt flag was hard-coded to 1 and never checked.

      Rate control bug with long key frame interval. · 9404c7db
      Paul Wilkins authored
      In two pass encodes, the calculation of the number of bits
      allocated to a KF group had the potential to overflow for high data
      rates if the interval is very long.
      
      We observed the problem in one test clip where there was one
      section where there was an 8000 frame gap between key frames.

      Make the quantizer exact. · e04e2935
      Timothy B. Terriberry authored
      This replaces the approximate division-by-multiplication in the
       quantizer with an exact one that costs just one add and one
       shift extra.
      The asm versions have not been updated in this patch, and thus
       have been disabled, since the new method requires different
       multipliers which are not compatible with the old method.

      cosmetics: trim trailing whitespace · 94c52e4d
      John Koleszar authored
      When the license headers were updated, they accidentally contained
      trailing whitespace, so unfortunately we have to touch all the files
      again.

      Make this/next iiratio unsigned. · cd475da8
      John Koleszar authored
      This patch addresses issue #79, which is a regression since commit
      28de670c "Fix RD bug." If the coded error value is zero, the iiratio
      calculation effectively multiplies by 1000000 by the
      DOUBLE_DIVIDE_CHECK macro. This can result in a value larger than
      INT_MAX, giving a negative ratio. Since the error values are
      conceptually unsigned (though they're stored in a double) this patch
      makes the iiratio values unsigned, which allows the clamping to work
      as expected.

      install includes in DIST_DIR/include/vpx, move vpx_codec/ to vpx/ · b7492341
      John Koleszar authored
      This renames the vpx_codec/ directory to vpx/, to allow applications
      to more consistently reference these includes with the vpx/ prefix.
      This allows the includes to be installed in /usr/local/include/vpx
      rather than polluting the system includes directory with an
      excessive number of includes.
