2014-01-03Modified Handling of min and max vbr rates.Paul Wilkins
In two pass encodes bits are allocated to each frame according to a modified error score for the frame as a fraction of the modified error score for the clip or section. Previously a minimum rate per frame was reserved and subtracted from the bits allocatable by the two pass code. The vbr max section rate was enforced by clipping the actual number of bits allocated. In this patch the min and max vbr rates are enforced instead by clipping the modified error scores for each frame rather than the number of bits allocated. Small gains for all test sets (psnr and SSIM) ranging from ~ +0.05 for YT psnr up to ~ +0.25 for Std-hd SSIM. Change-Id: Iae27d70bdd3944e3f0cceaf225bad2e8802833de

2013-12-27Adaptive motion control on ref and search rangeJingning Han
This commit takes a preliminary attempt to refine the motion search control. It detects the SAD associated with mv predictor per reference frame, and based on which to determine whether the encoder wants to reduce the motion search range (if the predicted mv provides fairly small SAD), or to skip the current reference frame (if there exists another ref frame that gives much smaller SAD cost). This feature is turned on in the settings of speed 1 and above. In speed 1, compression performance changed derf -0.018% yt -0.043% hd -0.045% stdhd -0.281% speed-up pedestrian_area_1080p at 4000 kbps 100 frames 199651ms -> 188846ms (5.5% speed-up) blue_sky_1080p at 6000 kbps 443531ms -> 415239ms (6.3% speed-up) In speed 2, compression performance changed derf -0.026% yt -0.090% hd -0.055% stdhd -0.210% speed-up pedstrian 113949ms -> 108855ms (4.5% speed-up) blue_sky 271057ms -> 257322ms (5% speed-up) Change-Id: I1b74ea28278c94fea329d971d706d573983d810d

2013-12-19Using single struct to represent scale factors.Dmitry Kovalev
Moving back to scale_factors struct. We don't need anymore x_offset_q4 and y_offset_q4 because both values are calculated locally inside vp9_scale_mv function. Change-Id: I78a2122ba253c428a14558bda0e78ece738d2b5b

2013-12-19Call set_scaled_offsets() just before scale_mv() call.Dmitry Kovalev
Before mv scaling it is required to calculate x_offset_q4/y_offset_q4 by calling set_scaled_offsets(). Now offset configuration can not be missed because it happens just before scale_mv(). Change-Id: I7dd1a85b85811a6cc67c46c9b01e6ccbbb06ce3a

Various cleanups and streamlining of interfaces as precursor to further advancements in rate control. Pre-encode parameter setting for different use cases: One-pass, first of 2-pass, second of 2-pass, and Svc are separated out. There is no change in output with this change.

2013-12-19Adjust gf_group_error_left for arf groups.Paul Wilkins
Take account of the fact that the overlay frame is usually very cheap so distribute target bits among the other frames. Change-Id: I120685122e8cbbe75da8d07d02932f7877059867
2013-12-19Allow arf just before kfs or end of sequence.Paul Wilkins
This will hurt metrics in some cases (particularly for static clips at low data rates where there is extra overhead, but it helps smooth transitions around forced key frames between stitched kf sections. Change-Id: I7e1026ae0de6c77bba863061e115136d7f283cc0
2013-12-19Further q estimate adjustment.Paul Wilkins
Slightly reduces the mean tendency to undershoot target rate in vbr, especially when using the memory less mode and when recodes are disabled. The effect is primarily at low q. Change-Id: I59a593b99522cc7da31b4134d1c8a65f5b7b7c53
