2014-04-24Remove key_frame_frequency variable from VP9_COMPAdrian Grange
This member of VP9_COMP seemed unnecessary since it only shadowed VP9EncoderConfig.key_freq that is accessible through VP9_COMP. Change-Id: Ib751bb1cf1b0b3c50a2a527d7c34f6829dd6fee3
2014-04-21Change naming of end_usage parameter.Paul Wilkins
The end_useage parameter is confusingly named since it now actually defines the rate control method used. Change-Id: I98912caabfe556b7af0b939a645d1336409e4d71

2014-04-17Removing cq_target_quality from VP9_COMP.Dmitry Kovalev
Use cq_level (which is identical) from VP9_CONFIG instead. Change-Id: I1aaf2fcef3d2dbd4577f613d27693ff8a68989fd
2014-04-17Merge two new VBR adjustment schemes.Paul Wilkins
To make direct side by side testing this patch combines two VBR corrections schemes to allow more direct side by side testing. (The other patch was by Debargha chg id I0cd1f7...) Change-Id: I271c45e5c4ccf8de8305589000218b80d9dc3a25
2014-04-16Add experimental VBR adaptation method.Paul Wilkins
Add code to monitor over and under spend and apply limited correction to the data rate of subsequent frames. To prevent the problem of starvation or overspend on individual frames (especially near the end of a clip) the maximum adjustment on a single frame is limited to a % of its un-modified allocation.

2014-04-16Merge "Fix rate control bug."Paul Wilkins
2014-04-16Fix rate control bug.Paul Wilkins
Fix rate control bug whereby the rate factor heuristics were being updated on arf overlays causing a rate surge for a few frames followed by a corrective drop. This fix eliminates many of the overshoot problems that we were seeing on hard clips (even without applying stricter vbr rate control) and also helps quality on almost all clips with some hard clips improving by >5%. Overall quality results measured at speed 2. Derf +1.78% opsnr , +2.44% SSIM Stdhd +2.41% opsnr, +2.85% SSIM Change-Id: I2369df6295c2705963fa6307877f6acb304bcc39

2014-04-11Adjust active minQ calculation for normal frames.Paul Wilkins
This increases the range of Q values available to normal inter frames to allow encoder a better chance to hit the target rate. Change-Id: I33cd96469a46577fdcea631e26d3355710909e6d
2014-04-11Change Qlimit for arf kf.Paul Wilkins
The limits applied under the flag "LIMIT_QRANGE_FOR_ALTREF_AND_KEY" behaved in an undesirable way if the gap between active_worst_quality and active_best_quality was changed. In this patch, the adjustment is made using the vp9_compute_qdelta_by_rate() function and fixed rate multiplier values. Hence it is not impacted by the relative value of active_best_quality.

2014-04-07vp9_ratectrl: change ARF overlays rate correction factorGuillaume Martres
ARF overlays now use the same rate correction factor as regular inter frames, further testing would be needed to see if it makes sense to use a completely separate rate correction factor for ARF overlays. $ vpxenc --cpu-used=5 --fps=50/1 --target-bitrate=2000 parkjoy.y4m -o out.webm => Before: 3356 kb/s => After: 2271 kb/s Change-Id: I73e4defa615ba7a8a2bdb845864f4b1721cbbffe

2014-04-02Adjust rate allocation in non-RD coding modeJingning Han
This commit reduces the frequency of frames using finer quantizer in non-RD coding flow, and slightly tune up the quantizer resolution when used. It provides 1.7% compression gains in speed -5 at no speed difference. Change-Id: I430249a51260a841a0402666e5ec1566e4f7d5a6
2014-04-02Add speed feature for recode tolerance.Paul Wilkins
