2013-09-24Limit mv search range for first pass and mbgraphYaowu Xu
Both first pass and mbgraph search use block size 16x16 for motion estimation. This commit put a limit of motion vector range. The effective range allows the entire 16x16 with required subpel interpolation input to be completely outside image border, but not any further away from image border.

2013-09-23Correct 3 step search site initialziationYaowu Xu
39c7b01d accidently reverted the row/col initialization, which broke mv clamps, which is dependent on the sites for valid motion vector range. This commit fixed the issue. Change-Id: Ibcce0226e0360b1ef483fe760b2e33f1af4bf494
2013-09-23Enable per transformed block zero coeffs forcingJingning Han
This commit enables forcing all coefficients zero per transformed block, when its rate-distortion cost is lower than regular coeff quantization. The overall performance improvement (including its parent patch on calculating rd cost per transformed block) at speed 1: derf: 0.298% yt: 0.452% hd: 0.741% stdhd: 0.006% Change-Id: I66005fe0fd7af192c3eba32e02fd6d77952accb5
2013-09-23Merge "Remove redundant mv_pred use for sub8x8 blocks"Jingning Han
2013-09-22Improves constant qual, constrained qual turned onDeb Mukherjee
Adds modeled functions to decide the qp for altref frames in constant q mode similar to other functions in use in bitrate mode. Also turns on the constrained quality mode (end-usage=2) option which was turned off before. Basic testing shows the mode works in principle, to cap bitrate to the target-bitrate specified, while allowing lower bitrate depending on the cq-level specified. The mode will need to be improved over time. Results for constant quality vs bitrate control mode: derfraw300/fullderfraw: +3.0% at constant quality over bitrate control. fullstdhdraw: +4.341% stdhdraw250: +5.361% Change-Id: If5027c9ec66c8e88d33e47062c6cb84a07b1cda9
2013-09-20Calculate rd cost per transformed blockJingning Han
This commit makes the rate-distortion optimization loop evaluate the rd costs of regular quantization and all zero coeffs, per transformed block. It improves speed 1 compression performance: derf: 0.245% yt: 0.515% For a large partition that consists multiple transformed blocks, this allows more flexibility to selectively force a portion of them coded as all zero coeffs, as well be continued in the next patches.

2013-09-19Remove redundant mv_pred use for sub8x8 blocksJingning Han
The sub8x8 blocks has its own motion vector reference scheme. The mv_pred is only used blocks of sizes 8x8 and above, to find the starting point for motion search. This change does not change any coding behavior. It makes the encoding process slightly faster. (0.5% speed-up for local test on speed 1.) Change-Id: I746ee6ef0eac19aa3621be014afa12be8d82cbb9
