2013-03-21Merge "Optimize 16x16 idct function" into experimentalYunqing Wang
2013-03-21Optimize 16x16 idct functionYunqing Wang
Wrote sse2 version of vp9_short_idct16x16 function. Compared to c version, the sse2 version is over 2.5X faster. Change-Id: I38536e2b846427a2cc5c5423aaf305fd0e605d61
2013-03-20Code cleanup: lower case variable names.Dmitry Kovalev
Renaming Width to width, Height to height and Version to version in several structs and function signatures. Change-Id: I084c3f7e747cb2ce3345aff27a3dff9b13a87543
2013-03-18Optimize 8x8 idct functionYunqing Wang
Wrote sse2 functions of vp9_short_idct8x8 and vp9_short_idct10_8x8. Compared to c version, the sse2 version is 2X faster. The decoder test didn't show noticeable gain since 8x8 idct doesn't take much of decoding time (less than 1% in my test). Change-Id: I56313e18cd481700b3b52c4eda5ca204ca6365f3
2013-03-18Replace scaling byte with explicit display sizeJohn Koleszar
If the intended display size is different than the size the frame is coded at, then send that size explicitly in the bitstream. Adds a new bit to the frame header to indicate whether the extra size fields are present. Change-Id: I525c66f22d207efaf1e5f903c6a2a91b80245854

2013-03-16Context-pred fix to not use top/left on edgesDeb Mukherjee
This fix resolves some of the mismatch issues being seen recently. While this is the right thing to do when tiling is used for this experiment, it is not the underlying cause of the the mismatches. Something else is causing writing outside of the allowable frame area in the encoder leading to this mismatch. Change-Id: If52c6f67555aa18ab8762865384e323b47237277
2013-03-15Faster vp9_short_fdct16x16.Christian Duvivier
Scalar path is about 1.5x faster (3.1% overall encoder speedup). SSE2 path is about 7.2x faster (7.8% overall encoder speedup). Change-Id: I06da5ad0cdae2488431eabf002b0d898d66d8289

2013-03-13Fix pulsing issue with scalingJohn Koleszar
Updates the YV12_BUFFER_CONFIG structure to be crop-aware. The exiting width/height parameters are left unchanged, storing the width and height algined to a 16 byte boundary. The cropped dimensions are added as new fields. This fixes a nasty visual pulse when switching between scaled and unscaled frame dimensions due to a mismatch between the scaling ratio and the 16-byte aligned sizes. Change-Id: Id4a3f6aea6b9b9ae38bdfa1b87b7eb2cfcdd57b6
2013-03-13Add VP9_GET_REFERENCE controlJohn Koleszar
This is like VP8_COPY_REFERENCE, but returns a pointer to the reference frame rather than a copy of it. This is useful when the application doesn't know what the size of the reference is, as is the case when scaling is in effect. Change-Id: I63667109f65510364d0e397ebe56217140772085

Enable entropy coding of motion vectors up to +/-2048. Also extend the motion search range accordingly. Change-Id: Iac2bb015e8934521cef83a19edbe967d9f097436

2013-03-11Minor optimization in mv entropy adaptationDeb Mukherjee
Adds a check to exit from the increment_nmv_count function when the increment is 0. Change-Id: I99c1e342d351f7800e23590f9c2419881bf1d708
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%. TODO: Need to further tune the rate control and motion search units. Change-Id: Ib842540a6796fbee5a797809433ef6a477c6d78d

This also changes the RD search to take account of the correct block index when searching (this is required for ADST positioning to work correctly in combination with tx_select). Change-Id: Ie50d05b3a024a64ecd0b376887aa38ac5f7b6af6
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
