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

2013-08-19Passing plane_bsize to foreach_transformed_block_visitor.Dmitry Kovalev
Updating all foreach_transformed_block_visitor functions to work with plane block size instead of general block. Removing a lot of duplicated code. Change-Id: I6a9069e27528c611f5a648e1da0c5a5fd17f1bb4
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
Creates a common encode (subtract, transform, quantize, optimize, inverse transform, reconstruct) function for all sb sizes, including the old 16x16 path. Change-Id: I964dff1ea7a0a5c378046a069ad83495f54df007

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.

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.

2012-12-18Use standard integer types for pixel values and coefficients.Ronald S. Bultje
For coefficients, use int16_t (instead of short); for pixel values in 16-bit intermediates, use uint16_t (instead of unsigned short); for all others, use uint8_t (instead of unsigned char). Change-Id: I3619cd9abf106c3742eccc2e2f5e89a62774f7da
2012-12-0732x32 transform for superblocks.Ronald S. Bultje
This adds Debargha's DCT/DWT hybrid and a regular 32x32 DCT, and adds code all over the place to wrap that in the bitstream/encoder/decoder/RD. Some implementation notes (these probably need careful review): - token range is extended by 1 bit, since the value range out of this transform is [-16384,16383]. - the coefficients coming out of the FDCT are manually scaled back by 1 bit, or else they won't fit in int16_t (they are 17 bits). Because of this, the RD error scoring does not right-shift the MSE score by two (unlike for 4x4/8x8/16x16). - to compensate for this loss in precision, the quantizer is halved also. This is currently a little hacky. - FDCT and IDCT is double-only right now. Needs a fixed-point impl. - There are no default probabilities for the 32x32 transform yet; I'm simply using the 16x16 luma ones. A future commit will add newly generated probabilities for all transforms. - No ADST version. I don't think we'll add one for this level; if an ADST is desired, transform-size selection can scale back to 16x16 or lower, and use an ADST at that level. Additional notes specific to Debargha's DWT/DCT hybrid: - coefficient scale is different for the top/left 16x16 (DCT-over-DWT) block than for the rest (DWT pixel differences) of the block. Therefore, RD error scoring isn't easily scalable between coefficient and pixel domain. Thus, unfortunately, we need to compute the RD distortion in the pixel domain until we figure out how to scale these appropriately. Change-Id: I00386f20f35d7fabb19aba94c8162f8aee64ef2b
