2013-03-07Optimize add_constant_residual functionYunqing Wang
Optimized adding constant diff to predictor, which gave about 2% decoder performance gain. Change-Id: I47db20c31428e8c4a8f16214a85cbe386a6e9303
2013-03-07Merge "Allocate 16-byte aligned diff buffer" into experimentalYunqing Wang
2013-03-07Allocate 16-byte aligned diff bufferYunqing Wang
This was done based on John's suggestion. Change-Id: I62516a513c31fe3dbea0d6cd063df79d9e819ec8
2013-03-07Update ADST selection if tx_size < block_size.Ronald S. Bultje
Change-Id: Ic9b336486774c95ffbb92adcb110cc0fc2a83cc5
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
2013-03-07Fix issue in add_residual intrinsic functionYunqing Wang
Yaowu found this function had a compiling issue with MSVC because of using _mm_storel_pi((__m64 *)(dest + 0 * stride), (__m128)p0). To be safe, changed back to use integer store instruction. Also, for some build, diff could not always be 16-byte aligned. Changed that in the code. Change-Id: I9995e5446af15dad18f3c5c0bad1ae68abef6c0d
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

2013-03-06Added stricter Q control flag.Paul Wilkins
Added a variant of the one shot maxQ flag for two pass that forces a fixed Q for the normal inter frames. Disabled by default. Also small adjustment to the Bits per MB estimation. Change-Id: I87efdfb2d094fe1340ca9ddae37470d7b278c8b8

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

2013-03-04Support 16K sequence codingJingning Han
Fixed a couple of variable/function definitions, as well as header handling to support 16K sequence coding at high bit-rates. The width and height are each specified by two bytes in the header. Use an extra byte to explicitly indicate the scaling factors in both directions, each ranging from 0 to 15. Tested coding up to 16400x16400 dimension.

2013-02-28Fix incorrect comparison of frame sizeJohn Koleszar
The width and height stored in the reference frames are padded out to a multiple of 16. The Width and Height variables in common are the displayed size, which may be smaller. The incorrect comparison was causing scaling related code to be called when it shouldn't have been. A notable case where this happens is 1080p, since 1088 != 1080.
