2013-03-28Framework changes in nzc to allow more flexibilityDeb Mukherjee
The patch adds the flexibility to use standard EOB based coding on smaller block sizes and nzc based coding on larger blocksizes. The tx-sizes that use nzc based coding and those that use EOB based coding are controlled by a function get_nzc_used(). By default, this function uses nzc based coding for 16x16 and 32x32 transform blocks, which seem to bridge the performance gap substantially. All sets are now lower by 0.5% to 0.7%, as opposed to ~1.8% before. Change-Id: I06abed3df57b52d241ea1f51b0d571c71e38fd0b
2013-03-28Fix mix-up in pt token indexing.Ronald S. Bultje
This fixes uninitialized reads in the trellis, and probably makes the trellis do something again. Change-Id: Ifac8dae9aa77574bde0954a71d4571c5c556df3c
2013-03-28Adjust mv_ratio_accumulator threshold.Paul Wilkins
This threshold effectively limits the amount of motion from one end of a GF/ARF group to the other. This patch makes the threshold depend on image size. Change-Id: Id45d1d7bced815f86ddd037be53164894b00b82f

2013-03-26Implicit weighted prediction experimentDeb Mukherjee
Adds an experiment to use a weighted prediction of two INTER predictors, where the weight is one of (1/4, 3/4), (3/8, 5/8), (1/2, 1/2), (5/8, 3/8) or (3/4, 1/4), and is chosen implicitly based on consistency of the predictors to the already reconstructed pixels to the top and left of the current macroblock or superblock. Currently the weighting is not applied to SPLITMV modes, which default to the usual (1/2, 1/2) weighting. However the code is in place controlled by a macro. The same weighting is used for Y and UV components, where the weight is derived from analyzing the Y component only. Results (over compound inter-intra experiment) derf: +0.18% yt: +0.34% hd: +0.49% stdhd: +0.23% The experiment suggests bigger benefit for explicitly signaled weights.

2013-03-26Add col/row-based coefficient scanning patterns for 1D 8x8/16x16 ADSTs.Ronald S. Bultje
These are mostly just for experimental purposes. I saw small gains (in the 0.1% range) when playing with this on derf. Change-Id: Ib21eed477bbb46bddcd73b21c5c708a5b46abedc
2013-03-26Redo banding for all transforms.Ronald S. Bultje
Now that the first AC coefficient in both directions use the same DC as their context, there no longer is a purpose in letting both have their own band. Merging these two bands allows us to split bands for some of the very high-frequency AC bands. In addition, I'm redoing the banding for the 1D-ADST col/row scans. I don't think the old banding made any sense at all (it merged the last coefficient of the first row/col in the same band as the first two of the second row/col), which was clearly an oversight from the band being applied in scan-order (rather than in their actual position). Now, coefficients at the same position will be in the same band, regardless what scan order is used. I think this makes most sense for the purpose of banding, which is basically "predict energy for this coefficient depending on the energy of context coefficients" (i.e. pt). After full re-training, together with previous patch, derf gains about 1.2-1.3%, and hd/stdhd gain about 0.9-1.0%. Change-Id: I7a0cc12ba724e88b278034113cb4adaaebf87e0c
2013-03-26Use above/left (instead of previous in scan-order) as token context.Ronald S. Bultje
Pearson correlation for above or left is significantly higher than for previous-in-scan-order (absolute values depend on position in scan, but in general, we gain about 0.1-0.2 by using either above or left; using both basically just makes this even better). For eob branch skipping, we continue to use the previous token in scan order. This helps about 0.9% on derf after re-training on a limited data set. Full re-training and results on larger-resolution clips are pending. Note that this commit breaks trellis, so we can probably get further gains out of it by fixing trellis at some later point.
