      Fixed the buffer overflow issue · 232ccc2f
      Jingning Han authored
      The issue that potentially broke the encoding process was due to the fact
      that the length of token link is calculated from the total number of tokens
      coded, while it is possible, in high bit-rate setting, this length is
      greater than the buffer length initially assigned to the cpi->tok.
      
      This patch increases the initially allocated buffer length assigned to
      cpi->tok from
      (mb_rows * mb_cols * 24 * 16) to (mb_rows * mb_cols * (1 + 24 * 16)).
      
      It resolves the buffer overflow problem.

      Avoid division in intra prediction · 56e6c66b
      Tero Rintaluoma authored
      - Using multiplication and shifting instead of division in
        intra prediction.
      - Maximum absolute difference is 1 for division statements
        in d45, d27, d63 prediction modes. However, errors can
        cumulate for large block sizes when using already predicted
        values.
      - Maximum number of non-matching result values in loops using
        division are:
        4x4        0/16
        8x8        0/64
        16x16     10/256
        32x32     13/1024
        64x64    122/4096

      fixed an enc/dec mis-match issue · b13f38d4
      Yaowu Xu authored
      The issue was caused by a out-of-order merge, which leads to wrong
      functions are called at lossless mode.
