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.

2013-02-08Pass macroblock index to pick inter functionsJohn Koleszar
Pass the current mb row and column around rather than the recon_yoffset and recon_uvoffset, since those offsets will change from predictor to predictor, based on the reference frame selection. Change-Id: If3f9df059e00f5048ca729d3d083ff428e1859c1
