2015-02-25Motion compensated reference refinementJingning Han
This commit applies one-step refinement search to the resulting motion vector of the integral projectiion based motion estimation, per 64x64 block. It improves the coding performance of speed -6. pedestrian 1080p 500 kbps 51735 b/f, 36.794 dB, 16044 ms -> 51382 b/f, 36.793 dB, 16282 ms cloud 1080p 500 kbps 24081 b/f, 37.988 dB, 14016 ms -> 23597 b/f, 38.076 dB, 12774 ms vidyo1 720p 1000 kbps 16552 b/f, 40.514 dB, 8279 ms -> 16553 b/f, 40.543 dB, 8510 ms The rtc set compression performance is improved by 0.5%.

2015-02-24Re-distribute hierarchical vector match patternJingning Han
This commit modifies the hierarchical vector match patter. It avoids repeated SAD computation at same points. The function vp9_vector_sad_sse2 is called 12 times per 64x64 block, instead of 15 times as before. The effective coverage remains the same. Change-Id: I91ad9d27d40db8963c907d02af84e10702136994

2015-02-24Fix ssse3 quantize_fp functions while skip=1Yunqing Wang
In ssse3 functions, DEFINE_ARGS macro hard codes qcoeff and dqcoeff to r3 and r4. If skip is 1, qcoeff and dqcoeff need to be loaded from the stack, which doesn't work because of the above definitions. Currently, skip=1 case is not used in the encoder. This patch fixed the issue, so it can be turned on later. Change-Id: I998d696b1a7a85dca2b3bcee790b21c21e039147

2015-02-23Account for rate error in GF group Q calculation.paulwilkins
When GF group adaptive maxQ is enabled this patch accounts somewhat for accumulated error in the rate control. This improves accuracy quite a bit on many clips especially when there is overshoot. Examples when the overshoot and undershoot command line parameters are set to 100: Hall @ 1200 overshoot is reduced from 67-24%. Akiyo @ 400 undershoot is reduced from 28%-15%. Setting a lower value for undershoot or overshoot still reduces the error further. Impact on metrics is mixed with some gains in average psnr but generally a little lower (e.g. 0.5%) on overall and ssim. The GF group adaptation is still off by default in this patch. Compared to with the head, enabling this mode now gives big average psnr gains on the YT sets (e.g. YT_HD >11.2%), a drop in overall PSNR (YT-HD 3.9%) and a smaller drop or neutral for SSIM.

2015-02-20Adjustments to cyclic refresh (aq-mode=3).Marco
Target higher delta-qp for big blocks with zero motion, and for segment#1: avoid 64x64 partition size and force 8x8 tx size. Metrics on RTC set mostly positive: SSIM up by ~4%, PSRN by ~1.5%. Doesn't seem to be any change in speed. Change-Id: I1f68fa3c4f62dab3b90cc58041f05ebb048ae5ac

2015-02-19Improve skip_txfm thresholds in the non-rd mode selectionYunqing Wang
Modified the thresholds of deciding whether or not to skip the transforms in model_rd_for_sb_y(). Used zbin[] instead of dequant[] to be more precise. Also, modified the checking coditions. Rtc set borg test results (at speed 6) showed: average PSNR gain: 0.138%, overall PSNR gain: 0.158%, and SSIM gain: 0.177%. The data rate test was modified slightly as suggested by Marco.

2015-02-19Integral projection based motion estimationJingning Han
This commit introduces a new block match motion estimation using integral projection measurement. The 2-D block and the nearby region is projected onto the horizontal and vertical 1-D vectors, respectively. It then runs vector match, instead of block match, over the two separate 1-D vectors to locate the motion compensated reference block. This process is run per 64x64 block to align the reference before choosing partitioning in speed 6. The overall CPU cycle cost due to this additional 64x64 block match (SSE2 version) takes around 2% at low bit-rate rtc speed 6. When strong motion activities exist in the video sequence, it substantially improves the partition selection accuracy, thereby achieving better compression performance and lower CPU cycles. The experiments were tested in RTC speed -6 setting: cloud 1080p 500 kbps 17006 b/f, 37.086 dB, 5386 ms -> 16669 b/f, 37.970 dB, 5085 ms (>0.9dB gain and 6% faster) pedestrian_area 1080p 500 kbps 53537 b/f, 36.771 dB, 18706 ms -> 51897 b/f, 36.792 dB, 18585 ms (4% bit-rate savings) blue_sky 1080p 500 kbps 70214 b/f, 33.600 dB, 13979 ms -> 53885 b/f, 33.645 dB, 10878 ms (30% bit-rate savings, 25% faster) jimred 400 kbps 13380 b/f, 36.014 dB, 5723 ms -> 13377 b/f, 36.087 dB, 5831 ms (2% bit-rate savings, 2% slower) Change-Id: Iffdb6ea5b16b77016bfa3dd3904d284168ae649c

2015-02-13Fix an encoder/decode mismatch bugYaowu Xu
This commit prevent the encoder to update last_frame_type when a frame is dropped in the encoder. Prior to this fix, if there is a dropped frame immediatedly after a key frame, decoder would have the value of last_frame_type as key frame, different from encoder as the dropped frame in encoder would have updated the value to an inter frame. This leads to different probability update in encoder and decoder, thereby encoder/decoder mismatch. This fixes issue #941 Change-Id: I27115224b138bec43ae3916c016574f5740822b0
