2013-07-01Quantize (64-bit only, for now) SSSE3 SIMD.Ronald S. Bultje
Total encoding time for first 50 frames of bus (speed 0) @ 1500kbps goes 2min34.8 to 2min14.4, i.e. a 10.4% overall speedup. The code is x86-64 only, it needs some minor modifications to be 32bit compatible, because it uses 15 xmm registers, whereas 32bit only has 8. Change-Id: I2df53770c2e850813ffa713e1a91b45b0082b904

2013-06-28Make coefficient skip condition an explicit RD choice.Ronald S. Bultje
This commit replaces zrun_zbin_boost, a method of biasing non-zero coefficients following runs of zero-coefficients to be rounded towards zero, with an explicit skip-block choice in the RD loop. The logic is basically that if individual coefficients should be rounded towards zero (from a RD point of view), the trellis/optimize loop should take care of it. If whole blocks should be zero (from a RD point of view), a single RD check is much more efficient than a complete serialization of the quantization loop. Quality change: derf +0.5% psnr, +1.6% ssim; yt +0.6% psnr, +1.1% ssim. SIMD for quantize will follow in a separate patch. Results for other test sets pending.

2013-06-28Optimize partition search orderYaowu Xu
This commit change the partition search order to allow checking of rectangular partition to be done after square partitions. It also added a speed feature to skip rectangular partition check when NONE is better than SPLIT in RD sense. This feature roughly speed up encoder by 1.5X with loss on compression -0.91% on cif set -0.56% on stdhd set Change-Id: I0d2d06993041aa9ea9073fcc39c54f73a127dfa4
