2013-09-23Remove redundant mode update in sub8x8 decodingJingning Han
The probability model used to code prediction mode is conditioned on the immediate above and left 8x8 blocks' prediction modes. When the above/left block is coded in sub8x8 mode, we use the prediction mode of the bottom-right sub8x8 block as the reference to generate the context. This commit moves the update of mbmi.mode out of the sub8x8 decoding loop, hence removing redundant update steps and keeping the bottom- right block's mode for the decoding process of next blocks.

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

2013-09-22Improves 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
