2013-03-11Changes to maximum gf/arf interval.Paul Wilkins
This patch puts in an adjustment to the maximum gf/arf interval based on the active q range. It sets a fixed baseline maximum of 16 but can drop this down to 12 at lower q. This required some re-ordering in the first pass code to insure we have a Q range estimate before defining the first gf sequence. The main gains seed are int he STD hd set on 50fps clips where previously the interval could rise as high as 25. On the std hd clip the gains are around 2.8% with limit set to 300 frames. When combined with the one shot rate control flags we get combined of: derf 1.55% (limit300), yt 7.25%, hd 5.17% std-hd 5.84% (limit300) Change-Id: Ib380d51354511f2ff0f171a8df4e74291c0421f9

2013-03-10Optimize vp9_tree_probs_from_distributionJohn Koleszar
The previous implementation visited each node in the tree multiple times because it used each symbol's encoding to revisit the branches taken and increment its count. Instead, we can traverse the tree depth first and calculate the probabilities and branch counts as we walk back up. The complexity goes from somewhere between O(nlogn) and O(n^2) (depending on how balanced the tree is) to O(n). Only tested one clip (256kbps, CIF), saw 13% decoding perf improvement. Note that this optimization should port trivially to VP8 as well. In VP8, the decoder doesn't use this function, but it does routinely show up on the profile for realtime encoding.

2013-03-08Extend diff MV limit from +/-256 to +/-1024Jingning Han
Increase the motion search range by 4x. Change MV_CLASS tree of the entropy coding to allow two additional mv classes to cover the extended motion vector limit. The codec determines the effective motion search range conditioned on the actual frame dimension. It provides coding gains: stdhd 0.39% yt 0.56% hd 0.47% Major coding performance gains are packed in several sequences with intense motion activities, e.g., ped_1080p gains 7% at high bit-rates, and on average 3%.

2013-03-07Fix issue in add_residual intrinsic functionYunqing Wang
Yaowu found this function had a compiling issue with MSVC because of using _mm_storel_pi((__m64 *)(dest + 0 * stride), (__m128)p0). To be safe, changed back to use integer store instruction. Also, for some build, diff could not always be 16-byte aligned. Changed that in the code. Change-Id: I9995e5446af15dad18f3c5c0bad1ae68abef6c0d
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
