The rules of the specification with regard to picture buffering for pyramid coding are widely ignored. x264's b-pyramid implementation, despite being practically identical to that proposed by the original paper, was technically not compliant. Now it is. Two modes are now available: 1) strict b-pyramid, while worse for compression, follows the rule mandated by Blu-ray (no P-frames can reference B-frames) 2) normal b-pyramid, which is like the old mode except fully compliant. This patch also adds MMCO support (necessary for compliant pyramid in some cases). MB-tree still doesn't support b-pyramid (but will soon).
