2014-07-01Re-design quantization processJingning Han
This commit re-designs the quantization process for transform coefficient blocks of size 4x4 to 16x16. It improves compression performance for speed 7 by 3.85%. The SSSE3 version for the new quantization process is included. The average runtime of the 8x8 block quantization is reduced from 285 cycles -> 255 cycles, i.e., over 10% faster.

2014-06-12Fast computation path for forward transform and quantizationJingning Han
This commit enables a fast path computational flow for forward transformation. It checks the sse and variance of prediction residuals and decides if the quantized coefficients are all zero, dc only, or more. It then selects the corresponding coding path in the forward transformation and quantization stage. It is currently enabled in rtc coding mode. Will do it for rd coding mode next. In speed -6, the runtime for pedestrian_area 1080p at 1000 kbps goes down from 14234 ms to 13704 ms, i.e., about 4% speed-up. Overall coding performance for rtc set is changed by -0.18%.

2014-02-26Cleaning up vp9_encodemb.c file.Dmitry Kovalev
Usage of encode_b_args is unnecessary because encode_block_pass1() doesn't use them. That's why optimize_init_b() call is also not required. Change-Id: Ib6cfe4916c2ca85749c90bb0adcba6fea592f9ac

2013-10-03Refactor inter mode rate-distortion searchJingning Han
This commit separates the rate-distortion optimization loop of superblocks from that of sub8x8 blocks. This allows better design rate-distortion optimization search loop for each setting. It also removes the use of SPLITMV and I4X4_PRED therein. No performance change in speed 0 settings. For bus@CIF at 2000kbps, the speed 1 runtime goes from 48009ms to 43894ms (about 10% faster). The overall compression performance on derf changed by -0.021%. Speed 2 runtime goes from 27114ms to 28700ms (6% slower), while the overall coding efficiency goes up by 1.629% for derf, 1.236% for yt. Change-Id: Ie6bdfa0a370148dd60bd800961077f7e97e67dd4

2013-08-19Using plane_bsize instead of bsize.Dmitry Kovalev
This change set is intermediate. The next one will remove all repetitive plane_bsize calculations, because it will be passed as argument to foreach_transformed_block_visitor. Change-Id: Ifc12e0b330e017c6851a28746b3a5460b9bf7f0b

2013-07-25Make coeff_optimize initialized per-planeJingning Han
This commit makes the initialization of trellis coeff optimization a per-plane operation, thereby eliminating the redundant steps in encode_sby and encode_sbuv. It makes the encoder at speed 0 slightly faster. Change-Id: Iffe9faca6a109dafc0dd69dc7273cbdec19b17cd
2013-07-02Calculate rd cost per transformed blockJingning Han
Compute the rate-distortion cost per transformed block, and cumulate the cost through all blocks inside a partition. This allows encoder to detect if the cumulative rd cost is already above the best rd cost, thereby enabling early termination in the rate-distortion optimization search.

2013-05-03Separate transform and quant from vp9_encode_sbJohn Koleszar
This allows removing a large number of transform size specific functions, as well as supporting 444/alpha by routing all code through the subsampling-aware path. Change-Id: Ieb085cebe9f37f24fc24de179898b22abfda08a4
2013-05-02Create common vp9_encode_sb{,y}John Koleszar

2013-04-23Move src_diff to per-plane MACROBLOCK dataJohn Koleszar
First in a series of commits making certain MACROBLOCK members addressable per-plane. This commit also refactors the block subtraction functions vp9_subtract_b, vp9_subtract_sby_c, etc to be loops-over-planes and variable subsampling aware. Change-Id: I371d092b914ae0a495dfd852ea1a3d2467be6ec3
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
2013-04-11Remove 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
2013-04-09Make SB coding size-independent.Ronald S. Bultje
Merge sb32x32 and sb64x64 functions; allow for rectangular sizes. Code gives identical encoder results before and after. There are a few macros for rectangular block sizes under the sbsegment experiment; this experiment is not yet functional and should not yet be used.

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
2013-02-26Spatial resamping of ZEROMV predictorsJohn Koleszar
This patch allows coding frames using references of different resolution, in ZEROMV mode. For compound prediction, either reference may be scaled. To test, I use the resize_test and enable WRITE_RECON_BUFFER in vp9_onyxd_if.c. It's also useful to apply this patch to test/i420_video_source.h: --- a/test/i420_video_source.h +++ b/test/i420_video_source.h @@ -93,6 +93,7 @@ class I420VideoSource : public VideoSource { virtual void FillFrame() { // Read a frame from input_file. + if (frame_ != 3) if (fread(img_->img_data, raw_sz_, 1, input_file_) == 0) { limit_ = frame_; } This forces the frame that the resolution changes on to be coded with no motion, only scaling, and improves the quality of the result.

2013-01-09New prediction filterAdrian Grange
This patch removes the old pred-filter experiment and replaces it with one that is implemented using the switchable filter framework. If the pred-filter experiment is enabled, three interopolation filters are tested during mode selection; the standard 8-tap interpolation filter, a sharp 8-tap filter and a (new) 8-tap smoothing filter. The 6-tap filter code has been preserved for now and if the enable-6tap experiment is enabled (in addition to the pred-filter experiment) the original 6-tap filter replaces the new 8-tap smooth filter in the switchable mode. The new experiment applies the prediction filter in cases of a fractional-pel motion vector. Future patches will apply the filter where the mv is pel-aligned and also to intra predicted blocks.
