2013-09-11New mode_info_context storage -- undo revertScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of pointers to MODE_INFO structs. The MODE_INFO structs are now stored as a stream (decoder only), eliminating unnecessary copies and is a little more cache friendly. Change-Id: I031d376284c6eb98a38ad5595b797f048a6cfc0d
2013-09-09Revert "New mode_info_context storage"James Zern
This reverts commit dae17734ece414091ba1184f7becd0aa6c0004f1 Encode crashes, leaks and increases integer overflow errors. Change-Id: I595aa2649bb8d0b6552ff91652837a74c103fda2
2013-09-06New mode_info_context storageScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of a pointer to a MODE_INFO struct and a "in the image" flag. The MODE_INFO structs are now stored as a stream, eliminating unnecessary copies and is a little more cache friendly. For the test clips used, the decoder performance improved by ~4.3% (1080p) and ~9.7% (720p). Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p) and 5.9% (720p).

2013-07-15Skip duplicate block encoding in the rd loopJingning Han
This speed feature allows the encoder to largely remove the spatial dependency between blocks inside a 64x64 superblock, thereby removing the need to repeatedly encode superblocks per partition type in the rate-distortion optimization loop. A major challenge lies in the intra modes tested in the rate-distortion optimization loop. The subsequent blocks do not have access to the reconstructed boundary pixels without the intermediate coding steps. This was resolved by using the original pixels for intra prediction in the rd loop, followed by an appropriately designed distortion modeling on the quantization parameters. Experiments also suggested that the performance impact is more discernible at lower bit-rate/psnr settings. Hence a quantizer dependent threshold is applied to deactivate skip of block coding. For bus_cif at 2000 kbps, speed 0: runtime 269854ms -> 237774ms (12% speed-up) at 0.05dB performance loss. speed 1: runtime 65312ms -> 61536ms, (7% speed-up) at 0.04dB performance loss. This operation is currently turned on in settings of speed 1. Change-Id: Ib689741dfff8dd38365d8c1b92860a3e176f56ec

And removed 1st pass specific version of intra coding funcitons Change-Id: Ia54e67c71d750957cb2efda8360bf2133468498a
2013-05-27a few clean-upsYaowu Xu
1. remove prediction mode conversion 2. unified bmode, same for key and non-key frame 3. set I4X4_PRED count for pdf to 0, as I4X4_PRED is no longer coded ever. It is determined by ref_frame and block partition Change-Id: If5b282957c24339b241acdb9f2afef85658fe47d
2013-05-27Reduce bmi buffer length from 16 to 4Jingning Han
This commit removes the use of bmi_ in the first-pass encoding by forcing encode_intra4x4block_ to use DC_PRED, followed by DCT_DCT only, as John suggested. This makes the need for bmi buffer only up to 4 entries, instead of 16. Change-Id: I3410007dfae789ee46a09ae20c39d3ce3c7954aa

2013-05-20WIP: 4x4 idct/recon mergeScott LaVarnway
This patch eliminates the intermediate diff buffer usage by combining the short idct and the add residual into one function. The encoder can use the same code as well. Change-Id: I296604bf73579c45105de0dd1adbcc91bcc53c22

2013-04-29Separate I4X4_PRED coding from macroblock modulesJingning Han
Separate the functionality of I4X4_PRED from decode_mb. Use decode_atom_intra instead, to enable recursive partition of superblock down to 8x8. Change-Id: Ifc89a3be82225398954169d0a839abdbbfd8ca3b
2013-04-26Remove BLOCKD structureJohn Koleszar

2013-04-26Merge "quantize: make 4x4, 8x8 common with larger transforms" into experimentalJohn Koleszar
2013-04-26Removed bmi from blockdScott LaVarnway
This originally was "Removed update_blockd_bmi()". Now, this patch removed bmi from blockd and uses the bmi found in mode_info_context. Eliminates unnecessary bmi copies between blockd and mode_info_context. Change-Id: I287a4972974bb363f49e528daa9b2a2293f4bc76
2013-04-25quantize: make 4x4, 8x8 common with larger transformsJohn Koleszar
There were 4 variants of the quantize loop in vp9_quantize.c, now there is 1. Change-Id: Ic853393411214b32d46a6ba53769413bd14e1cac
2013-04-25Remove diff from BLOCKDJohn Koleszar
The underlying storage for these buffers is in the per-plane MACROBLOCKD area, so read it from there directly. Change-Id: Id6bd835117fdd9dea07db95ad06eff9f12afaaf7
2013-04-25Remove BLOCK structureJohn Koleszar

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
2013-04-11Merge "WIP: removing predictor buffer usage from decoder" into experimentalScott LaVarnway
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
2013-04-11Remove unused macroblock versions of reconstruction functions.Ronald S. Bultje
More specifically, remove vp9_quantize_mb*, vp9_optimize_mb*, vp9_inverse_transform_mb* and vp9_transform_mb*. Instead, use the generic _sb* functions that take a size argument, and call them with BLOCK_SIZE_MB16X16. Change-Id: I33024afea95d3a23ffbc1df7da426e4645110f29
2013-04-04Move EOB to per-plane dataJohn Koleszar

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
2013-03-16Context-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
2013-03-07Re-add support for ADST in superblocks.Ronald S. Bultje
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. TODO: Training the default probs/counts for nzcs Change-Id: I951bc1e22f47885077a7453a09b0493daa77883d
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
