Change-Id: I4f51ce859a97bf1b8fd2b37ac585b7c643232b69
2013-12-02Remove plane_block_idx.Alex Converse
Its last remaining caller can be passed its results directly without any additional work. Also, it's not non-4:2:0 safe. Change-Id: Ia5089ba5f7f66c7617270483c619c9271aefd868
2013-10-28Cleaning up vp9_regular_quantize_b_4x4.Dmitry Kovalev
Passing scan & iscan as parameters, adding useful local variables. Change-Id: Ia2a87906941db9557350d273669ce5c3cdb7235d
2013-10-22Removing quantize_b_4x4 function pointer.Dmitry Kovalev
The pointer was asigned only once with vp9_regular_quantize_b_4x4, calling this function directly now. Also removing unused declarations: prototype_quantize_block prototype_quantize_block_pair prototype_quantize_mb vp9_regular_quantize_b_4x4_pair vp9_regular_quantize_b_8x8 Change-Id: I14325bc2f082336820671eafbc06126651b79f73

2013-07-15Inline vp9_quantize() in xform_quant().Ronald S. Bultje
Cycle times: 4x4: 151 to 131 cycles (15% faster) 8x8: 334 to 306 cycles (9% faster) 16x16: 1401 to 1368 cycles (2.5% faster) 32x32: 7403 to 7367 cycles (0.5% faster) Total encode time of first 50 frames of bus @ 1500kbps (speed 0) goes from 1min39.2 to 1min38.6, i.e. a 0.67% overall speedup.

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
2013-04-30Remove unused quantize optimizations.Johann
Files were copied from vp8 and never maintained. Change-Id: I9659a8755985da73e8c19c3c984423b6666d8871
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
2013-04-11Remove 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. Change-Id: I71f93b5d2a1596e99a6f01f29c3f0a456694d728
2013-04-04Move EOB to per-plane dataJohn Koleszar
Continue migrating data from BLOCKD/MACROBLOCKD to the per-plane structures. Change-Id: Ibbfa68d6da438d32dcbe8df68245ee28b0a2fa2c
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
2013-03-07Re-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
2013-03-04Make 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
2013-02-27Move eob from BLOCKD to MACROBLOCKD.Ronald S. Bultje

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
