2016-10-25Change 2 motion search counts to be tile dataYunqing Wang
This patch modified the motion search counts used in: https://chromium-review.googlesource.com/#/c/305640/ These 2 counts were originally added as thread data, and used to make decisions in motion search. The tile encoding order can be inconsistent while using different number of threads, which can cause bitstream mismatch. Here moved them to tile data to solve the issue.

2016-10-21vp9: Nonrd variance partition: increase threshold for using 4x4 avg.Marco
In variance partition low resolutions may use varianace based on 4x4 average for better partitioning. Increase the threshold for doing this at speed = 8. Improves speed by ~5%, with little loss, < 1%, on RTC_derf set. Change-Id: Ib5ec420832ccff887a06cb5e1d2c73199b093941
2016-10-17vp9: Non-rd variance partition: add condition for 64x64 split.Marco
Add stronger condition for splitting 64x64, for low noise content. This reduces dragging artifact near moving head. Little/no change in metrics on RTC set. Change-Id: I39b38cfd20f2ece53ff49c2aaf76ba9f82761be1
2016-10-111 pass vbr: Allow for lookahead alt-ref in real-time mode.Marco
For 1 pass vbr real-time mode: Allow for the usage of alt-ref frame when non-zero lag-in-frames is used. Use non-filtered alt-ref, and select usage based on fast scene/content analysis/detection within the lag of frames. Positive gains on ytlive set: overall avgPSNR ~3-4%. Several clips are up between 5-14%, a few clips are neutral/small change. Current speed decrease is about ~5-10%. Use the flag USE_ALTREF_FOR_ONE_PASS to enable this feature (off by default for now).

2016-09-01Casts to remove some warnings.paulwilkins
Added casts to remove warnings: BUG=webm:1274 In regards to the safety of these casts they are of two types:- - Normalized bits per (16x16) MB stored in a 32 bit int (This is safe as bits per MB even with << 9 normalization cant overflow 32 bits. Even raw 12 bits hdr source even would only be 29 bits :- (4+4+12+9) and the encoder imposes much stricter limits than this on max bit rate. - Cast as part of variance calculations. There is an internal cast up to 64 bit for the Sum X Sum calculation, but after normalization dividing by the number of points the result will always be <= the SSE value.

2016-08-25Create interface for the ALT_REF_AQ classYury Gitman
Current commit is just an API template for the rest of the code, and I will add inner logic later. Altref frames generate a lot of bitrate and at the same time other frames refer to them a lot, so it makes sense to apply special compensation-based adaptive quantization scheme for altref frames. E.g., for blocks that are good predictors for the future apply rate-control chosen quantizer while for bad predictors apply worse one. Change-Id: Iba3f8ec349470673b7249f6a125f6859336a47c8
2016-08-25Adjust coefficient optimization and tx_domain rd speed features.paulwilkins
Previously Tx domain rd was used in all cases above speed 0. Coefficient optimization was only enabled for best and speed 0. This patch selectively sets these features at other speed settings based on block complexity. For the Netflix and HD sets in particular the quality gains are large compared to the speed hit. At speed 1 the average psnr gain in the NF set is > 2.5% with one clip coming in at 18% and some points almost 30%. Average gains for the lower resolution test sets are around 1%. The gains are biggest at low Q so some further optimization may be possible. Change-Id: I340376c7b2a78e5389a34b7ebdc41072808d0576

2016-06-27vp9: Increase thr_var for 32x32 blocks in var-based partitioning.jackychen
For real-time mode, increase variance threshold for 32x32 blocks in var-based partitioning for resolution >= 720p, so that it is more likely to stay at 32x32 for high resolution which accelerates the encoding speed with little/no PSNR drop. PSNR effect on different speed settings: speed 8 rtc: 0.02 overall PSNR drop, 0.285% SSIM drop speed 7 rtc: 0.196% overall PSNR increase, 0.066% SSIM increase speed 5 rtc_derf: no effect. Speed up: gips_motion_WHD, 1mbps: 2.5% faster on speed 7, 2.6% faster on speed8 gips_stat_WHD, 1mbps: 4.6% faster on speed 7, 5.6% faster on speed8 Change-Id: Ie7c33c4d2dd7d09294917e031357fc5476c3a4bb

2016-06-22set interp_filter to SWITCHABLE_FILTER for intra blockAngie Chiang
In vp9_pick_inter_mode(), instead of using vp9_get_pred_context_switchable_interp(xd) to assign filter_ref, we use a less strict condition on assigning filter_ref. This is to reduce the probabily of entering the flow of not assigning filter_ref and then skipping filter search. Overall PSNR gain 0.074% for rtc dataset Details: Low Mid High 0.185% -0.008% -0.082% Change-Id: Id5c5ab38d3766c213d5681e17b4d1afd1529e676
2016-06-21Add a hardware compatibility featurehui su
This commit adds an encoder workaround to support better compatibility with a non-compliant hardware vp9 profile 2 decoder. The known issue with this decoder is: The decoder assumes a wrong value, 127 instead of the correct value of 511 and 2047, for any assumed top-left corner pixel in UV planes for 10 and 12 bit, respectively. Such assumed top-left corner pixel is used for INTRA prediction when a real decoded/reconstructed pixel is not avalable, e.g. when it is located inside the row above the top row or inside the column left to the leftest column of a video image.

2016-06-15vp9: Add bias to last frame in choose_partitioning.JackyChen
This change is only for real-time mode if short_circuit_low_temp_var is on. Add bias to last frame in choosing ref frame for partitioning, when y_sad and y_sad_g are close. It speeds up real-time encoding by 0.5% on some clips with less than 0.1% overall PSNR drop on rtc test set. Change-Id: I2a2110fe36455f3d8f0fc404aef2228f512e8df8

2016-06-13vp9: Encoding cycle reduction for speed 8.JackyChen
1. Skip golden non-zeromv and newmv-last for bsize >= 16x16 if the temporal variance obtained from choose_partitioning is very low. 2. Skip horz and vert INTRA mode for speed 8. This change works best on the clips with little noise and with some motion (e.g. gips_motion which has > 5% speed up). PSNR drop is 1.78% on rtc test set, no obvious visual quality regression found.

2016-06-08vp9: Use nonrd_pick_partition on scene-cut, for speed 5 vbr mode.Marco
On scene-cut detected frames (i.e., high_source_sad = 1), use nonrd_pick_partition (over choose_part + select_part), as the nonrd_pick partitioning is generally better. Small positive increase in metrics on ytlive set (~0.5 - 1%). Negligle overall speed decrease, as its only used on scene-cut frames. Only affects 1 pass vbr mode, speed = 5.

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.

In Aq mode 1 the segment and AQ delta for each block is based on spatial variance. There may be a net imbalance between blocks that have lower Q than the baseline value and those that have higher Q. This patch monitors that imbalance and extends the allowed baseline Q range for the frame to accommodate adjustment of that baseline value to compensate.
