2014-08-08Moving pass from VP9_COMP to VP9EncoderConfig.Dmitry Kovalev
We had a very complicated way to initialize cpi->pass from cfg->g_pass: switch (cfg->g_pass) { case VPX_RC_ONE_PASS: oxcf->mode = ONE_PASS_GOOD; break; case VPX_RC_FIRST_PASS: oxcf->mode = TWO_PASS_FIRST; break; case VPX_RC_LAST_PASS: oxcf->mode = TWO_PASS_SECOND_BEST; break; } cpi->pass = get_pass(oxcf->mode). Now pass is moved to VP9EncoderConfig and initialization is simple: switch (cfg->g_pass) { case VPX_RC_ONE_PASS: oxcf->pass = 0; break; case VPX_RC_FIRST_PASS: oxcf->pass = 1; break; case VPX_RC_LAST_PASS: oxcf->pass = 2; break; } Change-Id: I8f582203a4575f5e39b071598484a8ad2b72e0d9

2014-08-06Integrate fast txfm and quant path into skip_recode systemJingning Han
This commit integrates the fast transform and quantization process into skip_recode scheme in the rate-distortion optimization loop. Previously the fast transform and quantization process was only enabled for non-RD coding flow. Change-Id: Ib7db4d39b7033f1495c75897271f769799198ba8
2014-08-05Directly split the block in partition searchPengchong Jin
This patch allows the encoder to directly split the block in partition search, therefore skip searching NONE. It computes a score which measures whether 16x16 motion vectors from the first pass in the current block are consistent with each others. If they are inconsistent and we have enough Q to encode, split the block directly, and skip searching NONE. This feature is under flag CONFIG_FP_MB_STATS. In speed 2, it further gives a speedup of 3-8% on sample yt clips as compared to the previous version under the same flag. Overall, the features under the flag will give 7-15% on typical yt clips at up to 6000kbps data rate. The speedup at very high data rate is not significant. For hard stdhd clips: park_joy_1080p @ 15000kbps: 504541ms -> 506293ms (-0.35%) pedestrian_area_1080p @ 2000kbps: 326610ms -> 290090ms (+11.2%) The compression performance using the features under the flag: derf: -0.068% yt: -0.189% hd: -0.318% stdhd:-0.183% To use the feature, set CONFIG_FP_MB_STATS and turn on cpi->use_fp_mb_stats.

2014-07-30Early termination after partition NONE is done in RD.Pengchong Jin
This patch allows the encoder to skip the search for partition SPLIT, HORZ, VERT after the search for partition NONE is done in RD optimization. It uses the first pass block-wise statistics to make the decision. If all 16x16 blocks in the current partition have zero motions and small residues from the frist pass statistics, and it has small difference variance, further partition search is skipped. For speed 2 setting, experiments on general youtube clips show that the speedup varies from 1% - 10%, 5% on average. On the performance side in PSNR, derf 0.004%, yt -0.059%, hd -0.106%, stdhd 0.032%. For hard stdhd clips: park_joy_1080p, 502952 ms -> 503307 ms (-0.07%) pedestrian_area_1080p, 227049 ms -> 220531 ms (+3%) This feature is under the compilation flag CONFIG_FP_MB_STATS and it is off in current setting.

2014-07-30Chessboard pattern partition searchJingning Han
This commit enables a chessboard pattern constrained partition search for 720p and above resolutions. The scheme applies stricter partition search to alternative blocks based on its above/left neighboring blocks' partition range, as well as that of the collocated blocks in the previous frame. It is currently turned on at 16x16 block size level. The chessboard pattern is flipped per coding frame. The speed 3 runtime is reduced: park_joy_1080p, 652832 ms -> 607738 ms (7% speed-up) pedestrian_area_1080p, 215998 ms -> 200589 ms (8% speed-up) The compression performance is changed: hd -0.223% stdhd -0.295% Change-Id: I2d4d123ae89f7171562f618febb4d81789575b19

2014-07-15VP9 Denoiser denoises after mode/bsize searchTim Kopp
In vp8, statistics are collected about the different modes as they are searched. This process is more complicated due to the variable block size. Fields were added to the PICM_MODE_CONTEXT struct to hold this information for each point in the search. The information is then taken from the appropriate part of the tree during denoising.

This commit re-designs the quantization process for transform coefficient blocks of size 4x4 to 16x16. It improves compression performance for speed 7 by 3.85%. The SSSE3 version for the new quantization process is included. The average runtime of the 8x8 block quantization is reduced from 285 cycles -> 255 cycles, i.e., over 10% faster.

2014-06-30Decide the partitioning threshold from the variance histogramYunqing Wang
Before encoding a frame, calculate and store each 16x16 block's variance of source difference between last and current frame. Find partitioning threshold T for the frame from its variance histogram, and then use T to make partition decisions. Comparing with fixed 16x16 partitioning, rtc set test showed an overall psnr gain of 3.242%, and ssim gain of 3.751%. The best psnr gain is 8.653%. The overall encoding speed didn't change much. It got faster for some clips(for example, 12% speedup for vidyo1), and a little slower for others. Also, a minor modification was made in datarate unit test.

2014-06-26Adaptive txfm size selection depending on residual sse/varianceJingning Han
This commit enables an adaptive transform size selection method for speed -6. It uses largest transform size when the sse is more than 4 times of variance, i.e., most energy is compacted in the DC coefficient. Otherwise, use the default TX_8X8. It improves the compression efficiency for rtc set of speed -6 by 0.8%, no speed change observed. Change-Id: Ie6ed1e728ff7bf88ebe940a60811361cdd19969c
