Avoid two GF only groups just before a kf Trap the case where we end up with two short GF only groups just before a key frame. For example, if the KF is 22 frames away we are better doing one ARF group of size 16 followed by a GF only group of 6 than two GF only groups of size 11 (when min_gf_interval is 12).
