2014-03-07Merge "Use modeled rate distortion costs for non-RD mode"Jingning Han
2014-03-06Use modeled rate distortion costs for non-RD modeJingning Han
This commit replaces SAD cost with modeled rate-distortion cost for non-RD mode decision. It translates the prediction residual SSE into estimate rate and reconstruction distorion costs, hence capturing the quantization setting effect. The compression performance of speed -7 for rtc set is improved by 14.79%. Change-Id: Ifda014eb0501d13109fe7f92680bf1410b463632

This funtion initializes buffer pointers and first stage motion vector prediction. It will be needed by both regular rate-distortion optimization loop and the non-RD mode decision. Hence move its declaration in vp9_rdopt.h Change-Id: I64e8b6316c9d05f20756a62721533a2e4d158235

2013-10-16Implement variance-based adaptive quantizationGuillaume Martres
This should be similar to what x264 does with --aq-mode 1. It works well with clips like parkjoy and touhou (http://x264.nl/developers/Dark_Shikari/LosslessTouhou.mkv). At low bitrates, the segmentation signaling overhead may negate the benefits of this feature. (PGW) Default changed to feature OFF to allow provisional merge.

2013-10-11Change in rddiv parameter to make it a power of 2Deb Mukherjee
Converts the constant rddiv parameter to 128 (from 100) and implements RDCOST with bit-shift rather than multiplication. Other parameters are also adjusted to roughly keep the same balance between Rate and Distortion. There is a slight speed-up of about 0.5-1% (at speed 0) as testted on football_cif. There is a slight change in performance due to small change in the parameters. derfraw300: +0.033% stdhdraw250; +0.102% Change-Id: I70ac69f58fa71c83108f68fe41796cd19d1fc760
2013-10-03Refactor inter mode rate-distortion searchJingning Han
This commit separates the rate-distortion optimization loop of superblocks from that of sub8x8 blocks. This allows better design rate-distortion optimization search loop for each setting. It also removes the use of SPLITMV and I4X4_PRED therein. No performance change in speed 0 settings. For bus@CIF at 2000kbps, the speed 1 runtime goes from 48009ms to 43894ms (about 10% faster). The overall compression performance on derf changed by -0.021%. Speed 2 runtime goes from 27114ms to 28700ms (6% slower), while the overall coding efficiency goes up by 1.629% for derf, 1.236% for yt. Change-Id: Ie6bdfa0a370148dd60bd800961077f7e97e67dd4

2013-07-17Best_rd breakout in rd partition search.Ronald S. Bultje
About 15% faster for bus (speed 0) first 50 frames @ 1500kbps, which goes from 1min36 to 1min24. Results become slightly better (+0.2% on derf/yt, +0.4% on hd), probably because of a bugfix for skipmode in super_block_yrd(). Overall speed change (on derfraw300) is roughly -13%. This can probably be improved further by caching best_yrd between partition searches. Also, we might be able to get more speedups by always doing PARTITION_NONE before PARTITIONS_SPLIT, not just at the sb8x8 level. Change-Id: I83736949ebd5b4a3b400ee688d7661913fefc98b
2013-07-15Skip duplicate block encoding in the rd loopJingning Han
This speed feature allows the encoder to largely remove the spatial dependency between blocks inside a 64x64 superblock, thereby removing the need to repeatedly encode superblocks per partition type in the rate-distortion optimization loop. A major challenge lies in the intra modes tested in the rate-distortion optimization loop. The subsequent blocks do not have access to the reconstructed boundary pixels without the intermediate coding steps. This was resolved by using the original pixels for intra prediction in the rd loop, followed by an appropriately designed distortion modeling on the quantization parameters. Experiments also suggested that the performance impact is more discernible at lower bit-rate/psnr settings. Hence a quantizer dependent threshold is applied to deactivate skip of block coding. For bus_cif at 2000 kbps, speed 0: runtime 269854ms -> 237774ms (12% speed-up) at 0.05dB performance loss. speed 1: runtime 65312ms -> 61536ms, (7% speed-up) at 0.04dB performance loss. This operation is currently turned on in settings of speed 1. Change-Id: Ib689741dfff8dd38365d8c1b92860a3e176f56ec
2013-06-21Implement SSE2 block_error.Ronald S. Bultje
Change vp9_block_error() to return a 64bit error variable, change all callers to expect a 64bit return value (this will prevent overflows, which we basically don't check for at all right now). Remove duplicate block_error() function, which fixed that through truncation. Remove old (incompatible) mmx/sse2 block_error SIMD versions and replace with a new one that returns a 64bit value. Encoding time of first 50 frames of bus @ 1500kbps goes from 3min29 to 3min23, i.e. a 3% overall speedup. Change-Id: Ib71ac5508b5ee8a80f1753cd85d72df1629abe68

2013-04-10Make RD superblock mode search size-agnostic.Ronald S. Bultje
Merge various super_block_yrd and super_block_uvrd versions into one common function that works for all sizes. Make transform size selection size-agnostic also. This fixes a slight bug in the intra UV superblock code where it used the wrong transform size for txsz > 8x8, and stores the txsz selection for superblocks properly (instead of forgetting it). Lastly, it removes the trellis search that was done for 16x16 intra predictors, since trellis is relatively expensive and should thus only be done after RD mode selection. Gives basically identical results on derf (+0.009%). Change-Id: If4485c6f0a0fe4038b3172f7a238477c35a6f8d3

2013-02-26Spatial resamping of ZEROMV predictorsJohn Koleszar
This patch allows coding frames using references of different resolution, in ZEROMV mode. For compound prediction, either reference may be scaled. To test, I use the resize_test and enable WRITE_RECON_BUFFER in vp9_onyxd_if.c. It's also useful to apply this patch to test/i420_video_source.h: --- a/test/i420_video_source.h +++ b/test/i420_video_source.h @@ -93,6 +93,7 @@ class I420VideoSource : public VideoSource { virtual void FillFrame() { // Read a frame from input_file. + if (frame_ != 3) if (fread(img_->img_data, raw_sz_, 1, input_file_) == 0) { limit_ = frame_; } This forces the frame that the resolution changes on to be coded with no motion, only scaling, and improves the quality of the result.
