2016-06-02Disable short circuit feature for low temporal variance.JackyChen
The featrue fails in libvpx_unit_tests-valgrind. Will re-enable it after fixing the issue. Change-Id: I8ba132f04e98f4615b31fbff2097eda83c5e42bc
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.

Move the logic for rechecking zeromv on denoised block out to simplify the function. To simplify the param passing, add a new structure VP9_PICKMODE_CTX_DEN which is only used when denoiser is enabled. Change-Id: Iaa9b4396dfcb8147236c02d4a1868a09103a4476

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.
