2016-06-07Revert "remove vp9_diamond_search_sad_avx.c"Scott LaVarnway
This reverts commit be12fefa4b7d224e9f39275a6bb4fab01b8bae3b and commit 057c1c4034ba5b9bf360c5c1f600ebc6d0718c3a. Also, the mismatch between the avx version and the c version has been fixed. BUG=https://bugs.chromium.org/p/webm/issues/detail?id=1168 For a rt encode using 1080p@60fps material, up to 11% performance improvement overall was seen.

2016-06-07Avoid a potential assertion fail in optimize_b()hui su
The eob of a block is not perperly set when skip_recode is true, thus triggering assert(eob <= default_eob) to fail. Change-Id: Ifecbe33dce2dc4903e0a80bd384dc09bf0dd8a44
2016-06-07vp9: Replace the avg_size_inter metric, for 1 pass vbr.Marco
Code cleaup, use existing rolling_actual/target metrics instead, set threshold to get same/similar effect. Little/no change in metrics on ytlive set. Change-Id: I74f3c3d0a143a9cf20dc9c3dee54c0f7e6a97a51
2016-06-07vp9: Small ajustment to settings gf_interval, 1 pass vbr.Marco
Add a max condition and lower the min value. No change in behavior (metrics for yt live set) for the default min/max_gf_interval=4/16 settings. Small positive change when min/max_gf_interval=7/16 (for 60fps clips on ytlive set). Change-Id: I1c1d72425c86c69419ea43fb9730130e81062f91

2016-06-03Slightly more damped VBR adjustment.paulwilkins
Increase in the damping used in adjusting the active Q range. This does hurt rate accuracy a little in a few extreme cases especially if the clip is very short*, but helps metrics. * Note that the adjustment is applied at the GF/ARF group level based on what happened in the last group. Hence for very short clips where the length of a single group may be a significant % of the clip length there is still scope for some drift that cannot be accommodated. In practice most data points in our test sets are now much closer to target than was previously the case with default settings and in some cases are better even than they were with the command line undershoot and overshoot parameter was set very low (e.g. 2%). For example in bridge_close at high rates the old mechanism was unable to adapt enough to prevent extreme overshoot. Change-Id: I634f8f0e015b5ee64a9f0ccaa2bcfdbc1d360489
2016-06-03Change to get_twopass_worst_quality()paulwilkins
Change to the calculation of the error divisor used in get_twopass_worst_quality(). This follows on from other changes to the rate control that impact the output of this function. Change-Id: I414fa9aa1e6a68a64dccea17c3712f44b8a0c10c
2016-06-03Removed unused data structure.paulwilkins
Removed unused element from TWOPASS data structure. Change-Id: I9b662fd8eea727a7978055bc14f7c7328f048a5e
2016-06-03Adjustment to VBR rate correction.paulwilkins
Changes to the function the redistributes bits from overshoot or undershoot throughout the rest of the clip to respond more quickly. Change-Id: I90f10900cdd82cf2ce1d8da4b6f91eb5934310da
2016-06-03Adjustment calculation of active worst quality.paulwilkins
Added a factor based on the bit spend in the last arf group vs the target to adjust the choice of the active worst quality in subsequent groups. Helps clips where previously there was a big overshoot or undershoot to adapt and get closer to the target rate. Change-Id: I67034b801679b99024409489a2273ea6fe23b8e6
2016-06-03Remove gf_zeromotion_pct.paulwilkins
The use of this value is preventing rate adjustment on clips or sections that have very little motion but high noise and this can give rise to some sections with massive overshoot. Change-Id: I9a65c7c1148dc5d3a7d8b23e50fc1733f3661621
2016-06-02vp9: Fix valgrind failure for short circuit on low temporal vaiance block.JackyChen

2016-06-01vp9: Skip some modes when variance is low for big blocks, for 1 pass real-time.jackychen
Skip intra-mode and some inter-modes (newmv, nearmv, nearestmv) for golden frame if the variance got from choose_partitioning is very low. Only for 1 pass real-time CBR mode and bsize >= 32x32, it has ~2.5% speed up with less than 0.1% PSNR drop for rtc test set. Don't see visual regression.

2016-05-31vp9: Skip computation of best_sad for newmv, unless needed.Marco
For non-rd pickmode: best_pred_sad, computed for NEWMV-last, is only used for skipping golden non-zero modes. Add condition to avoid this computation if not used (i.e, if golden nonzero modes are not used). And remove code for computing best_pred_sad for NEWMV-golden, since that sad is not used. No change in behavior; small speed gain (~1%) for svc encodes. Change-Id: Ic2cbdef6c4e9a233a57c0db0eeac8ad5fcead366

2016-05-27Upgrade fwht4x4_mmx() to fwht4x4_sse2() for vp9 and vp10.Linfeng Zhang
Function level timing test shows about 27% time saving on a Xeon E5-2680 v2 desktop. Rename vp9_dct_sse2.c to vp9_dct_intrin_sse2.c for vp9 and rename dct_sse2.c to dct_intrin_sse2.c for vp10 to avoid duplicate basenames. Actually vp9_fwht4x4_mmx/sse2() and vp10_fwht4x4_mmx/sse2() are identical. TODO: They should be unified later if there is no intention to keep a duplicate.

2016-05-11vp9: Fix to quality regression issue for 1 pass.Marco
BUG=https://bugs.chromium.org/p/webm/issues/detail?id=1217 Issue introduced in https://chromium-review.googlesource.com/#/c/339162/. The factor on avg_frame_qindex[INTER_FRAME] in that CL, used for q-basis to set active_best, can cause the QP to decrease too slowly or get stuck in some cases when max-q=63. Removing that factor fixes the regression in issue#1217. Change-Id: I97fe28dca3c2bc2d852b1775f39c62164e032d4f

2016-05-11Fixed 8K two pass encoder crash.paulwilkins
Bug found by Yunqing relating to the correction for size at 8K and above in get_twopass_worst_quality(). The basis for the correction was changed to the linear size relative to 1080P as a baseline and the adjustment has been clamped to prevent problems at extreme images sizes. For 1080P the results on our test sets were neutral but the low res and mid res sets saw a small gain (0.1%-0.2% average). I would also expect some gains on 4k and larger content where the previous correction was overly aggressive. Change-Id: I30b026b5f4535e9601e3178d738066459d19c8fb

2016-05-09pickmode: Fix a pair of unsigned overflows.Alex Converse
block_variance: This operates on 8x8s and would be safe with a int32 * int32 to uint32 multiply, but this is potentially unsafe for 12-bit input. Unfortunately the code already segfaults on 12-bit input: https://bugs.chromium.org/p/webm/issues/detail?id=1223 calculate_variance: This operates on up to a 32x32 of 8x8s and can overflow even with 8-bit input (log2((256*32*32)**2) == 36).

2016-05-05vp9: Reduce qp threshold for limiting cyclic refresh on steady blocks.Marco
Makes the delta-qp stop little earlier on areas that have been refreshed enough. This helps to reduce some pulsing artifact on noisy flat areas observed in some noisy vc-clips. Threshold changes only take effect for sources where noise level is estimated to be >= medium level. Only affects 1 pass CBR, non-screen content case.
