Libtheora tracks an estimated cost of coding a frames as an intra and will switch if its expects a net win. In multi-pass encoding we could use this data for optimal placement (via Dijkstra over the directed graph formed by all possible keyframe constraint windows in all contiguous segments where the estimated cost of using a keyframe is positive), although preliminary testing didn't show much benefit. This may be due to accuracy problems in the current estimates.
