2013-04-18make buid_inter_predictors block size agnostic (luma)John Koleszar
This commit converts the luma versions of vp9_build_inter_predictors_sb to use a common function. Update the convolution functions to support block sizes larger than 16x16, and add a foreach_predicted_block walker. Next step will be to calculate the UV motion vector and implement SBUV, then fold in vp9_build_inter16x16_predictors_mb and SPLITMV. At the 16x16, 32x32, and 64x64 levels implemented in this commit, each plane is predicted with only a single call to vp9_build_inter_predictor. This is not yet called for SPLITMV. If the notion of SPLITMV/I8X8/I4X4 goes away, then the prediction block walker can go away, since we'll always predict the whole bsize in a single step. Implemented using a block walker at this stage for SPLITMV, as a 4x4 "prediction block size" within the BLOCK_SIZE_MB16X16 macroblock. It would also support other rectangular sizes too, if the blocks smaller than 16x16 remain implemented as a SPLITMV-like thing. Just using 4x4 for now. There's also a potential to combine with the foreach_transformed_block walker if the logic for calculating the size of the subsampled transform is made more straightforward, perhaps as a consequence of supporing smaller macroblocks than 16x16. Will watch what happens there. Change-Id: Iddd9973398542216601b630c628b9b7fdee33fe2

2013-04-18Make the use of pred buffers consistent in MB/SBJingning Han
Use in-place buffers (dst of MACROBLOCKD) for macroblock prediction. This makes the macroblock buffer handling consistent with those of superblock. Remove predictor buffer MACROBLOCKD. Change-Id: Id1bcd898961097b1e6230c10f0130753a59fc6df

2013-04-16Recursive partition syntax codingJingning Han
Enable recursive partition information coding from SB64X64 down to MB16X16. The bit-stream syntax is now supporting rectangular block sizes. It starts from SB64X64 and recursively describes the partition type of the current block. If the partition type is PARTITION_NONE, the block is coded as a single unit; if it is PARTITION_HORZ or PARTITION_VERT, the block is segmented into two independently coded rectangular units, with no further partition needed; otherwise, the block is segmented into 4 square blocks. i.e., PARTITION_SPLIT case, each can be potentially further partitioned. Forward adaptive probability modeling is used for the partition information coding, conditioned on the current block size. Change-Id: I499365fb547839d555498e3bcc0387d8a3587d87

2013-04-16Merge "Optimize the scaling calculation" into experimentalYunqing Wang
2013-04-16Optimize the scaling calculationYunqing Wang
In decoder, the scaling calculation, such as (mv * x_num / x_den), is fairly time-consuming. In this patch, we check if the scaling happens or not at frame level, and then decide which function to call to skip scaling calculation when no scaling is needed. Tests showed a 3% decoder performance gain. Change-Id: I270901dd0331048e50368cfd51ce273dd82b8733

2013-04-11WIP: removing predictor buffer usage from decoderScott LaVarnway
This patch will use the dest buffer instead of the predictor buffer. This will allow us in future commits to remove the extra mem copy that occurs in the dequant functions when eob == 0. We should also be able to remove extra params that are passed into the dequant functions. Change-Id: I7241bc1ab797a430418b1f3a95b5476db7455f6a

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
2013-03-26Implicit 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.

2013-03-07Coding con-zero count rather than EOB for coeffsDeb Mukherjee
This patch revamps the entropy coding of coefficients to code first a non-zero count per coded block and correspondingly remove the EOB token from the token set. STATUS: Main encode/decode code achieving encode/decode sync - done. Forward and backward probability updates to the nzcs - done. Rd costing updates for nzcs - done. Note: The dynamic progrmaming apporach used in trellis quantization is not exactly compatible with nzcs. A suboptimal approach has been used instead where branch costs are updated to account for changes in the nzcs.

2013-03-04Make superblocks independent of macroblock code and data.Ronald S. Bultje
Split macroblock and superblock tokenization and detokenization functions and coefficient-related data structs so that the bitstream layout and related code of superblock coefficients looks less like it's a hack to fit macroblocks in superblocks. In addition, unify chroma transform size selection from luma transform size (i.e. always use the same size, as long as it fits the predictor); in practice, this means 32x32 and 64x64 superblocks using the 16x16 luma transform will now use the 16x16 (instead of the 8x8) chroma transform, and 64x64 superblocks using the 32x32 luma transform will now use the 32x32 (instead of the 16x16) chroma transform. Lastly, add a trellis optimize function for 32x32 transform blocks. HD gains about 0.3%, STDHD about 0.15% and derf about 0.1%. There's a few negative points here and there that I might want to analyze a little closer. Change-Id: Ibad7c3ddfe1acfc52771dfc27c03e9783e054430
