2016-01-22Short circuit flat blocks when coding screen content at realtime speed.Alex Converse
In inter mode search skip all modes except NEARESTMV and DC_PRED. 10% less encode latency for large frames using the chromium remoting_perftests. +0.313% BDRATE on the screencast set at speed -6. Change-Id: Ib97a39dd8bcdeab545509e0e02d78ce7033f8c63
2015-07-08Changes to use of rectangular partitions.paulwilkins
Changes to allow more use of rectangular partitions at speeds 1 and 2 for content classed by the first pass as animation and for blocks near the active image edge. This has quite a big impact in quality for the animated test sequence but also hurts encode speed for speed 2. For other content types the impact on both speed and quality is small. Added some plumbing for detection of internal vertical image edges. Change-Id: I3fc48de2349f8cb87946caaf0b06dbb0ea261a9a
2015-07-08Change speed and rd features for formatting bars.paulwilkins
Change speed features / behavior for split mode when there is an internal active edge (e.g. formatting bars). Remove some threshold constraints in rd code near the active edge of the image. Add some plumbing for left and right active edge detection. Patch set 5. Limit rd pass through for sub 8x8 to internal active edges. This takes away any speed penalty for most clips but keeps the enhanced edge coding for the more critical case of internal image edges Change-Id: If644e4762874de4fe9cbb0a66211953fa74c13a5
2015-03-20Experimental rd bias based on source vs recon variance.paulwilkins
This experiment biases the rd decision based on the impact a mode decision has on the relative spatial complexity of the reconstruction vs the source. The aim is to better retain a semblance of texture even if it is slightly misaligned / wrong, rather than use a simple rd measure that tends to favor use of a flat predictor if a perfect match can't be found. This improves the appearance of texture and visual quality on specific test clips but is hidden under a flag and currently off by default pending visual quality testing on a wider Yt set.

2014-10-13Refactor rate distortion cost structureJingning Han
This commit makes a struct that contains rate value, distortion value, and the rate-distortion cost. The goal is to provide a better interface for rate-distortion related operation. It is first used in rd_pick_partition and saves a few RDCOST calculations. Change-Id: I1a6ab7b35282d3c80195af59b6810e577544691f

vp9_rdopt is for making rd optimal mode decisions. vp9_rd is for all other rd related routines. Anything used outside of making an rd optimal decision belongs in rd. Change-Id: I772a3073f7588bdf139f551fb9810b6864d8e64b

This commit allows the non-RD mode decision flow to select prediction filter type in NEWMV mode. It provides 8.14% compression performance gains in both settings of AQ=0 and 3. The current speed impact is about 5% to 10% slower. Change-Id: Id66ecebf77abd8f90fb3f6a066c0e8dfb4bf1c42

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

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
