2014-06-18Modify non-rd intra mode checkingYunqing Wang
Speed 6 uses small tx size, namely 8x8. max_intra_bsize needs to be modified accordingly to ensure valid intra mode checking. Borg test on RTC set showed an overall PSNR gain of 0.335% in speed -6. This also changes speed -5 encoding by allowing DC_PRED checking for block32x32. Borg test on RTC set showed a slight PSNR gain of 0.145%, and no noticeable speed change.

2014-06-18Separate rate-distortion modeling for DC and AC coefficientsJingning Han
This is the first step to rework the rate-distortion modeling used in rtc coding mode. The overall goal is to make the modeling customized for the statistics encountered in the rtc coding. This commit makes encoder to perform rate-distortion modeling for DC and AC coefficients separately. No speed changes observed. The coding performance for pedestrian_area_1080p is largely improved: speed -5, from 79558 b/f, 37.871 dB -> 79598 b/f, 38.600 dB speed -6, from 79515 b/f, 37.822 dB -> 79544 b/f, 38.130 dB Overall performance for rtc set at speed -6 is improved by 0.67%.

2014-06-16skip the un-necessary motion search in the first passPengchong Jin
This patch allows the VP9 encoder to skip the un-necessary motion search in the first pass. It computes the motion error of 0,0 motion using the last source frame as the reference, and skips the further motion search if this error is small. Borg test shows overall the patch gives PSNR gain (derf -0.001%, yt 0.341%, hd 0.282%). Individual clips may have PSNR gain or loss. The best PSNR performance is 7.347% and the worst is -0.662%. The first pass encoding speedup for slideshow clips is over 30%. Change-Id: I4cac4dbd911f277ee858e161f3ca652c771344fe

2014-06-12Fast computation path for forward transform and quantizationJingning Han
This commit enables a fast path computational flow for forward transformation. It checks the sse and variance of prediction residuals and decides if the quantized coefficients are all zero, dc only, or more. It then selects the corresponding coding path in the forward transformation and quantization stage. It is currently enabled in rtc coding mode. Will do it for rd coding mode next. In speed -6, the runtime for pedestrian_area 1080p at 1000 kbps goes down from 14234 ms to 13704 ms, i.e., about 4% speed-up. Overall coding performance for rtc set is changed by -0.18%.

2014-06-12skip un-neccessary motion search in the first passPengchong Jin
This patch allows the encoder to skip the un-neccessary motion search in the first pass. It calculates the error of the zero motion vector using the last source frame as reference and skips the further motion search in the first pass if the error is small. The encoding speedup of the first pass for slideshow videos is over 30%. Borg test shows the overall PSNR performance remain approximately the same (derf -0.009, hd 0.387, yt 0.021, stdhd 0.065). Individual clips may have either PSNR gain or loss. The worst PSNR perfomance is from yt set, with a PSNR loss of -1.1. Change-Id: I08b2ab110b695e4689573b2567fa531b6457616e
