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

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

2016-06-02Slow pshufb removal in 3 intra prediction functions.Linfeng Zhang
Replaced vpx_d45_predictor_4x4_ssse3(), vpx_d45_predictor_8x8_ssse3() and vpx_d207_predictor_4x4_ssse3() with created vpx_d45_predictor_4x4_sse2(), vpx_d45_predictor_8x8_sse2() and vpx_d207_predictor_4x4_sse2() respectively. It's mostly neutral or slightly worse than ssse3 in good cases and better than ssse3 in the bad cases (but still worse than using the mmx regs). Change-Id: Ib0237ceb71d2c57b8a93fd3170330cfed9d56bdd

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

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.

C does not allow for shifting into the sign bit of a signed integer, and the two instances here become signed ints via promotion. Explcitly cast them to unsigned MEM_VALUE_T to avoid the problem.
