2017-11-09vp9-svc: Avoid minmax variance for non-reference frames.Marco
For choose_partitioning (speed >= 6): avoid computation of minmax variance for non-reference frames in SVC. Existing condition only avoided this for speed >= 8. Combine that existing logic with non-reference condition. Small speedup (~0.5-1%) for 3 layer SVC, neutral change on avgPSNR/SSIM metrics. Change-Id: I3e9f3a1af0647b15e475cf170d9402908d672ee5
2017-11-09vp9: SVC feature to use partition from lower resolution.Jerome Jiang
For SVC with 3 spatial layers: Add feature to copy/upscale partition from middle spatial layer to the upper/highest resolution, when superblock sad is not high. Enabled for speed >= 7 and only for non-reference frames. Speedup ~3-4%, small loss in avgPNSR/SSIM of ~1%. Change-Id: I7f0a2716c0fde28bade0f86159d11b7e31d6ab8d

2017-11-09Fix to frames considered in arf boost calculation.paulwilkins
For a chosen interval "i" the existing arf boost calculation examined frames +/- (i-1) frames from the current location in the second pass. This change checks to make sure that the forward search does not extend beyond the next key frame in the event that the distance to the next key frame is < (i - 1). Small metrics gains on all our test sets but these are localized to a few clips (e.g. midres set psnr-hvs sintel -2.59% but overall average was only -0.185%) Change-Id: I26fc9ce582b6d58fa1113a238395e12ad3123cf6

2017-11-08CVBR command line option.paulwilkins
Added command line control of Corpus VBR. The new corpus vbr mode is a variant of standard VBR (end-usage=0) where the complexity distribution mid point is passed in rather than calculated for a specific clip or chunk. The new variant is enabled by setting a new command line parameter --corpus-complexity to a zero value. Omitting this parameter or setting it to 0 will cause the codec to use standard vbr mode. The correct value for a given corpus needs to be derived experimentally using a training set such that the average rate for the corpus is close to the target value. For example our using our low res test set with upper and lower vbr limits of 50%-150% and a corpus complexity value of 650 gives a similar average data rate across the set to using standard vbr. However, with the corpus mode easier clips will be allocated fewer bits and harder clips more bits rather than having the same rate target for all.

2017-11-06Nonrd_pickmode: avoid computing UV cost when early_term is set.Marco
For nonrd_pickmode: if early_term is set there should be no need to include UV in rdcost (when color_sensitivity is set). Neutral change on RTC and RTC_derf metrics, for speed >= 5. No change for ytlive metrics. Very small speed gain (~0.5%) on some clips with strong color content. Change-Id: Ifc00928ecd935fc71e94935ceef0ae7481249f07

2017-11-03Compound prediction mode for nonrd pickmode.Marco
Allow for compound prediction mode in nonrd_pickmode for ZEROMV. For real-time encoding, 1 pass with non-zero lag-in-frames. Added speed feature to control the feature. Enabled for speed >=6 for now, under VBR mode. avgPSNR/SSIM metrics positive on ytlive set, for speed 6: some clips up by ~3-5%, some clips neutral gain, average gain across clips is ~1%. Small/negligible decrease in speed. Change-Id: I7a60c7596e69b9a928410c5ee2f9141eecd8613d

2017-10-23vp9-svc: Allow for adapt_rd_thresh with row-mt.Marco
Set adaptive_row_thresh_mt = 1 at speed >= 7, for svc when multi-threading is used with row-mt. This allow the adaptive_rd_thresh feature to be used in the nonrd-pickmode. ~1-2% speedup for SVC encoding with small quality loss (< 0.6%) on RTC set.

2017-10-11Prevent double application of min rate in two pass.paulwilkins
The initial allocation of bits in the two pass code to each frame should be within the min max limits on the command line. However, when forming an ARF group the cost of the ARF is shared by frames in that group such that the residual bits for a frame could drop below the min value. This change prevents the minimum being re-applied after the cost of the ARF has been deducted as this may otherwise cause low rate sections to overshoot their target. Test runs comparing to a baseline run with min and max section pct 0-2000% vs one closer to the YT use case (50-150%) suggest that this fix not only results in better rate control but also gives a better rd outcome. For example the HD set vs 0-2000% baseline (opsnr, ssim). Old code (50-150): +0.751, +1.099 New code(50-150): +0.241, -0.009 Change-Id: I715da7b130bf53ba8aa609532aa9e18b84f5e2ef

2017-10-10Adjustment to scene detection and key frame.Marco
For 1 pass vbr: use higher threshold on avg_sad and force key frame under scene cut detection if above the threshold. Allow it for speed >= 6 for now, since it does not use the full nonrd_pickmode partition (as in speed 5). Improves quality somewhat on scene cut frames. Neutral on overall metrics and fps for speed 6 on ytlive set. Change-Id: I12626f7627419ca14f9d0d249df86c7104438162

2017-10-10Further Corpus VBR change.paulwilkins
Change to the bit allocation within a GF/ARF group. Normal VBR and CQ mode allocate bits to a GF/ARF group based of the mean complexity score of the frames in that group but then share bits evenly between the "normal" frames in that group regardless of the individual frame complexity scores (with the exception of the middle and last frames). This patch alters the behavior for the experimental "Corpus VBR" mode such that the allocation is always based on the individual complexity scores.

2017-10-10Corpus Wide VBR test implementation.paulwilkins
This patch makes further changes to support an experimental corpus wide VBR mode that uses a corpus complexity number as the midpoint of the distribution used to allocate bits within a clip, rather than some average error score derived from the clip itself. At the moment the midpoint number is hard wired for testing and the mode is enabled or disabled through a #ifdef. Ultimately this would need to be controlled by command line parameters.
