      Switch order of gm parameters for affine model · bec4fbe4

      This was originally subtracting 1 from the wrong element in the
      parameter set.

      Change the B-frame coding structure. · b20d0777
      Wei-ting Lin authored
      Originally we can have a BRF right before an overlay frame (in
      display order), which might be unnecessary since we already has a
      quality backward reference frame (ARF).
      This patch avoids such a coding structure and improves the RD
      performance by 0.086% in Avg in the lowres dataset, and 0.153 in
      Avg in the midres dataset.
      
      In the lowres dataset, significant gains are obtained for the
      following sequences:
      
      mobisode2_240p: 0.563%
      keiba_240p: 0.440%
      bus_cif: 0.336%
      soccer_cif: 0.333%
      
      And the performance drops only in the following four video sequences:
      
      motherdaughter_cif: 0.028%
      bqsquare_240p: 0.017%
      basketballpass_240p: 0.015%
      bowing_cif: 0.006%
