2016-09-29Fix an issue in vp9_first_pass for non-mulitple of 16 resolutionsDeepa K G
This patch sets the 16x16 src_diff to zero and ensures correct calculation of this_error for block sizes smaller than 16x16. Change-Id: I7b7c02d267433c9f22c8ac9b8d5df2f499175172
2016-09-26vp9: Reduce frame loopfilter-level for 1 pass cbr.Marco
Reduce the filt_guess for 1 pass cbr on inter-frames. This reduces visual artifact seen in rtc clip (jimred.vga), and improves metrics on rtc set. Metrics on rtc set for cbr mode overall positive, most clips are up: Speed 7 rtc: avgPSNR/SSIM up by: ~2.6/3.9% Speed 8 rtc: avgPSNR/SSIM up by: ~1.3/2.5% Change-Id: Ia4eccea1c19d65b583516df28823cd756c49464f

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.

2016-08-31Modified resize loop constraints.paulwilkins
Using a tighter resize constraint on undershoot seems to help results (especially SSIM) as significant undershoot on a frame seems to have more of a damaging impact than overshoot. This patch has been tuned so that in local testing using the derf set it is encode speed neutral for speed setting 2. Average quality result for speed 2 (psnr,ssim) were as follows:- lowres 0.039, 0.453 midres 0.249, 0.853 hdres 0.159, 0.659 NetFlix -0.241, 0.360 Change-Id: Ie8d3a0d7d6f7ea89d9965d1821be17f8bda85062

2016-08-26Add ALLOW_RECODE_FIRST speed mode.paulwilkins
This patch is to address concerns that changes to allow recodes on the first frame in each ARF group do not give a good enough speed quality trade off for speed 2. Though the average impact on encode speed is 1-2%, for some hard clips it is > 5% rise. For speed 1 this is less an issue and for Speed 0 the previous patch actually improves speed.

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
2016-08-24Add --alt-ref-aq=<int> optionYury Gitman
In the future this option will activate adaptive quantization special for altref frames. Encoder will create the adaptive quantization map on the basis of lookahead buffers similarity which is the estimate of the future motion compensation performance.
