x264 | branch: master | Lamont Alston <wewk584 at gmail.com> | Wed Jun 16 10:05:17 2010 -0700| [40c8c4926a78a705c263e042a780d63ca24687f4] | committer: Jason Garrett-Glaser 

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.
