A patch on compound inter-intra prediction. In compound inter-intra prediction, a new predictor for 16x16 inter coded MBs are obtained by combining a single inter predictor with a 16x16 intra predictor, in a manner that the weight varies with distance from the top/left boundary. The current search strategy is to combine the best inter mode with the best intra mode obtained independently. Results so far: derf +0.31% yt +0.32% std-hd +0.35% hd +0.42% It is conceivable that the results would improve somewhat with a more thorough search strategy where all intra modes are searched given the best mv, or even a joint search for the best mv and the best intra mode.
