2017-07-22set_var_thresh_from_histogram: prevent negative varianceJames Zern
For 8-bit the subtrahend is small enough to fit into uint32_t. For 10/12-bit apply: 63a37d16f Prevent negative variance previously: 47b9a0912 Resolve -Wshorten-64-to-32 in highbd variance. c0241664a Resolve -Wshorten-64-to-32 in variance. Change-Id: I181c85f0b9a03da37c2e8b89482d48aa3dbc0aee

2017-07-18vp9: Allocate alt-ref in denoiser for SVC.Jerome Jiang
When SVC is used, allocate alt-ref in denoiser. Change-Id: I1b17221b55b9444cd23b97d481b54ff8d296d857
2017-07-18vp9: Remove isolated skin & non-skin blocks.Jerome Jiang
0.007% regression on rtc and 0.004% gain on rtc_derf. 1 thread on QVGA,VGA and HD has ~0.2% speed regression while 2 threads has ~0.2% speed gain on Google Pixel. Change-Id: Ia4a6ec904df670d7001e35e070b01e34149d23dc
2017-07-18vp9: Disable usage of sb_use_mv_part for SVC.Marco
To fix valgrind issueis with SVC tests. SVC encoding uses prune_evenmore which is causing uinit value. Will re-enable later when issue is resolved. Change-Id: I257ff878cf78197ddd813db056582a4d5fe94f44
2017-07-17vp9: Fix to setting content_state for real-time mode.Marco
When content_state_sb is set to LowVarHighSumdiff, don't reset it to VeryHighSad. Visually better on clips with strong lighting changes. Small/negligible change in RTC metrics and speed. Change-Id: I20c383e3c4cf8d1149de5f9260449c0b7cf7c6aa
2017-07-17vp9: Reuse motion from choose_partitioning in NEWMV search.Marco
When int_pro_motion_estimation is done for superblock in choose_partitioning, use it to avoid the full_pixel_search for NEWMV mode, if bsize is >= 32X32. For speed > 7. Small/neutral change on RTC metrics. ~1-2% speedup on arm on high motion clip. Change-Id: I3cfe6833ff4bf75d4afa83eaf058ad45729de85b

2017-07-11Reintroduce fix for max qindex calculation of a gf intervalJim Bankoski
This reintroduces the fix: https://chromium-review.googlesource.com/c/422807/ and later reverted here: https://chromium-review.googlesource.com/c/447843/ BUG=webm:1355 This time behind a compile time flag : configure --disable-always_adjust_bpm configure --enable-always_adjust_bpm This should make side by side testing easier and let users of the lib pick which way they want to go.

2017-07-11vp9: Fix to SVC and denoising for fixed pattern case.Marco
For fixed pattern SVC: keep track of denoised last_frame buffer for base temporal layer, and if alt_ref is updated on middle/upper temporal layers, force an update to denoised last_frame buffer. This allows for improved denoising on top temporal layers. Change-Id: Icbd08566027d4d2eabc024d3b7a0d959d2f8c18b

This code is unused in vp9. Only vp8 still contains references to vpx_sad_NxMx[3|8] and only for sizes 16x16, 16x8, 8x16, 8x8 and 4x4. Remove the remaining sizes and all the highbitdepth versions. BUG=webm:1425 Change-Id: If6a253977c8e0c04599e25cbeb45f71a94f563e8

2017-07-06vp9: Nonrd mode: use content_state_sb for high motion.Marco
In the content_state for a superblock is set to HighSad, use that to bias some decisions in variance partition and nonrd pickmde: use int_pro_motion for sad computation in choose_partitioning, and set large_block in pickmode based on the content_state_sb. Only affects speed >= 7. Immprovement for high motion content. Small gain (~1%) in RTC metrics. Speedup of ~5 for high motion clip on android (speed 8, 1 thread).
