Open-GOP support
Allows B-frames immediately prior to keyframes (in display order).
This helps reduce keyframe popping and improve compression with short keyframe intervals.
Due to a staggering display of braindamage in the Blu-ray spec, two open-GOP modes are available.
The two modes calculate keyframe interval differently: one based on coded distance and one based on display distance.
The latter is superior compression-wise, but for no comprehensible reason, Blu-ray requires the former if open-GOP is used.
