  • Ticket #1166 – Description

    initial v2  
    33I am trying to code a GOP structure of 4 low-delay-P configuration, where frames 1,2,3 are non-reference frames and frame is 0 a reference frame. Below is the encoder configuration I use:

     5{{{
    56#======== Coding Structure =============
    67IntraPeriod                   : -1          # Period of I-Frame ( -1 = only first)
     
    1213Frame3:  P    3   2        0.4624   0            0               1           3                3         -3 -7 -11          1      -1       4         1 1 1 0         
    1314Frame4:  P    4   1        0.578    0            0               0           3                3         -4 -8 -12          1      -1       4         1 1 1 0

    1617Generated bitstream differs from the above specified structure in creating reference picture lists in the first two GOPs, frames 2,3,6 and 7. For these frames, the picture lists include additional reference frames. The rest of the bitstream is correct.
