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

2014-06-09Use small transform size in non-rd real-time modeYunqing Wang
In non-rd real-time mode, choosing smaller transform size in encoding gives better video quality and good speed gain than choosing larger transform size. This patch set tx size search method to ALLOW_8X8, which is better than using 4x4 or other larger sizes. Borg tests on rtc set at speed 6 showed significant gain on quality. PSNR gain: 11.034% and SSIM gain: 15.466%. The speed gain is 5% - 12% for <720p clips, and 2% - 7% for 720p clips. Change-Id: If4dc74ed2df359346b059f47fb73b4a0193ec548

2014-06-06Revert "Removing this_frame_stats member from TWO_PASS struct."Adrian Grange
Use of stack frame variable "fps" beyond the lifetime of the function. fps is sent as a paremeter to output_stats and stored in the packet holding this encoded frame. This has scope beyond the lifetime of the calling function. This reverts commit 3f95a230c7e54104201b3f6c577dfa9251b4642a Change-Id: Icd8e14b3d7dd733590ada12e619b9dce95b6b0f5

2014-06-03Fix AQ mode 2 bug where delta causes Q 0.Paul Wilkins
In Aq mode 2 for kf/arf/gf the segment q delta is calculated and then applied by re-quantization without going through the rd loop again. If the base Q != 0 but the segment Q == 0 (lossless) this can could give rise to a situation where we have an illegal combination of transform size and Q. (Q == 0 requires that all blocks are coded 4x4 WHT). Change-Id: I241a58c6494ed442e9e4630070b0cde0fb99ae45
