2017-10-11vp9: use nonrd pick_intra for small blocks on keyframes.Jerome Jiang
Keyframe encoding is more than 2x faster. Disabled on Speed 8. Change-Id: I2157318b6ac8253fa5398322c72d98cd7fa9b2b6
2017-10-06Adjust threshold in scene detectionMarco
For 1 pass vbr: increase min_thresh slightly, and also add condition on golden/arf update for using full nonrd_pick_partition. Reduces possible false detection for scene cut detection. Neutral/small change in metrics or speed for speed 5. Change-Id: I388f4d9a56e3cc763e0148338c1bc0381e58ad76
2017-10-04Avoid nonrd_pick_partition for speed >= 6.Marco
For 1 pass vbr speed >= 6: when REFERENCE_PARTITION is selected, avoid doing the full nonrd_pickmode based partition. No change in overall metrics or speed. Reduces encode times on scene cuts by 10-20%. Change-Id: I0310b1610cc1c83793a509e0a9059840e8f18308
2017-10-03Use adapt_partition for ARF in 1 pass.Marco
For speed 6 real-time mode: use adapt_partition on ARF frame instead of REFERENCE_PARTITION (which is slower). This requires enabling compute_source_sad_onepass for no-show_frames. Speedup of ~3-5% on some clips that heavily use ARF, small loss (~0.2%) in quality on ytlive set. Change-Id: Ib50acc97df06458244a6ac55d2bd882c30012536
2017-09-28vp9: Modification to adapt the ARF usage for 1 pass vbrMarco
Add stats for past ARF usage, and use it to disable ARF usage based on some conditions. Overall improvement on ytlive set, reduces the regression on the problem clips for this feature. Only affects when sf->use_altref_onepass is enabled (currently off by default). Change-Id: I66267f227ea132dc86acb730e9882f85bead2cdb
2017-09-18vp9: Adjustments for ARF usage in 1 pass vbr.Marco
Only when USE_ALT_REF_ONE_PASS is enabled (off by default). Force fixed partition to 64x64 when is_src_alt_ref_frame is true, and don't force early exit for some modes in nonrd_pickmode for ARF noshow frames. Small gain ~0.2% on ytlive metrics for speed 6. Neutral speed difference. Change-Id: I27eb6622d0453c09a06ccdc3b16368762474d11d
2017-08-25vp9: Speed 6 adapt_partition for live/vbr usage.Marco
Enable adapt_partition for vbr mode for speed 6. This allows the usage of the pickmode-based partition (used in speed 5), but only selectively for superblocks with high source sad, otherwise the faster variance based partition scheme is used. For speed 6 on ytlive set: avgPSNR/SSIM metrics up by ~0.6%, several clips up by ~1.5%. Small/negligible decrease in speed. Change-Id: I12f3efef6b3e059391de330fdbe5a44c2587f1f8
2017-08-24vp9: Adjust 16x16 splot threshold for variance partitionMarco
For speeds < 7, increase threshold that controls the split of 16x16->8x8 blocks, for resolutions 720p and higher. Minor change for speed 5 (since it uses reference partition scheme which only uses variance partition as first step). For speed 6: ~0.5% increase in avgPSNR/SSIM metrics on ytlvie set. No change in speed. Change-Id: I5126580973201538d8ca26a9256b93c4d11d685b
2017-08-22vp9: Condition lighting change detection on CBR mode.Marco
This feature is used for the CBR RTC encoding mode at speed >= 6. This change will exclude it for VBR mode. For speed 6 live encoding (VBR): avgPSNR/SSIM metrics on ytlive set up by ~1% (few clips up by 2/3%). No change in speed. Change-Id: I1a0dd94c334f7df309ab5a48d477d7e25355b798
2017-08-08vp9: Partition logic adjustment for speed 6 feature.Marco
When adapt_partition_source_sad is enabled (currently only at speed 6 for resoln <= 360p): use lower subsize (8x8 instead of 16x16) for nonrd_select_partition on 32X32 blocks. And force avoiding rectangular partition checks in nonrd_pick_partition for speed >= 6. Small increase ~0.5 in metrics for speed 6 on rtc_derf, no change in speed.

2017-07-30vp9: Fix denoising condition when pickmode partition is used.Marco
When the superblock partition is based on the nonrd-pickmode, we need to avoid the denoising. Current condition was based on the speed level. This change is to make the condition at the superblock level, as the switch in partitioning may be done at sb level based on source_sad (e.g., in speed 6).

2017-07-29vp9: Speed feature to adapt partition based on source_sad.Marco
Move the source_sad feature to speed 6 (from speed 7), and add speed feature to switch from the variance-based partition to reference_partition (which uses nonrd-pickmode for bsize selection) if source_sad is high. Currently used only for speed 6 for resoln <= 360p. About 4-5% improvement on 360p in RTC set. Some speed slowdown, but still ~30% faster than speed 5.

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.

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).

2017-04-24Make the row based multi-threaded encoder deterministicYunqing Wang
This patch followed allow_exhaustive_searches feature modification and continued to modify the encoder to achieve the determinism in the row based multi-threaded encoding. While row-mt = 1 and using multiple threads, the adaptive feature in encoder was disabled, which gave BDRate gain(at speed 1, -0.6% ~ -0.7%; at speed 2, -0.46% ~ -0.59%), but some encoder speed losses(7% ~ 10% at speed 1 and 3% ~ 6% at speed 2). These speed losses were acceptable considering the speed gains obtained from row-mt. Change-Id: I60d87a25346ebc487a864b57d559f560b7e398bb

2017-04-21Make allow_exhaustive_searches feature no longer adaptiveYunqing Wang
A previous patch turned on allow_exhaustive_searches feature only for FC_GRAPHICS_ANIMATION content. This patch further modified the feature by removing the exhaustive search limit, and made it no longer adaptive. As a result, the 2 counts that recorded the number of motion searches were removed, which helped achieve the determinism in the row based multi-threading encoding. Tests showed that this patch didn't cause the encoder much slower. Used exhaustive_searches_thresh for this speed feature, and removed allow_exhaustive_searches. Also, refactored the speed feature code to follow the general speed feature setting style. Change-Id: Ib96b182c4c8dfff4c1ab91d2497cc42bb9e5a4aa
