Adds support for switchable interpolation filters. Allows for swtiching/setting interpolation filters at the MB level. A frame level flag indicates whether to use a specifc filter for the entire frame or to signal the interpolation filter for each MB. When switchable filters are used, the encoder chooses between 8-tap and 8-tap sharp filters. The code currently has options to explore other variations as well, which will be cleaned up subsequently. One issue with the framework is that encoding is slow. I tried to do some tricks to speed things up but it is still slow. Decoding speed should not be affected since the number of filter taps remain unchanged. With the current version, we are up 0.5% on derf on average but some videos city/mobile improve by close to 4 and 2% respectively. If we did a full-search by turning the SEARCH_BEST_FILTER flag on, the results are somewhat better. The framework can be combined with filtered prediction, and I seek feedback regarding that. Rebased. Change-Id: I8f632cb2c111e76284140a2bd480945d6d42b77a

Compound inter-intra experiment 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.

New inter mode context This change is a fix / extension of the newbestrefmv experiment. As such it is presented without IFDEF. The change creates a new context for coding inter modes in vp9_find_mv_refs(). This replaces the context that was previously calculated in vp9_find_near_mvs(). The new context is unoptimized and not necessarily any better at this stage (results pending), but eliminates the need for a legacy call to vp9_find_near_mvs(). Based on numbers from Scott, this could help decode speed by several %. In a later patch I will add support for forward update of context (assuming this helps) and refine the context as necessary.

Adds support for switchable interpolation filters. Allows for swtiching/setting interpolation filters at the MB level. A frame level flag indicates whether to use a specifc filter for the entire frame or to signal the interpolation filter for each MB. When switchable filters are used, the encoder chooses between 8-tap and 8-tap sharp filters. The code currently has options to explore other variations as well, which will be cleaned up subsequently. One issue with the framework is that encoding is slow. I tried to do some tricks to speed things up but it is still slow. Decoding speed should not be affected since the number of filter taps remain unchanged. With the current version, we are up 0.5% on derf on average but some videos city/mobile improve by close to 4 and 2% respectively. If we did a full-search by turning the SEARCH_BEST_FILTER flag on, the results are somewhat better. The framework can be combined with filtered prediction, and I seek feedback regarding that. Rebased. Change-Id: I8f632cb2c111e76284140a2bd480945d6d42b77a

Remove vp8 in local symbols. For non-static functions, change the prefix to vp9_. For static functions, remove the prefix. Also fix some comments, remove unused code or unused function prototypes. Change-Id: I1f8be05362f66060fe421c3d4c9a906fdf835de5

Adaptive entropy coding of coefficients, modes, mv. This patch incorporates adaptive entropy coding of coefficient tokens, and mode/mv information based on distributions encountered in a frame. Specifically, there is an initial forward update to the probabilities in the bitstream as before for coding the symbols in the frame, however at the end of decoding each frame, the forward update to the probabilities is reverted and instead the probabilities are updated towards the actual distributions encountered within the frame. The amount of update is weighted by the number of hits within each context. Results on derf/hd/std-hd are all up by 1.6%. On derf, the most of the gains come from coefficients, however for the hd and std-hd sets, the most of the gains come from the mode/mv information updates.
