2018-07-23vp9: Adjust reset segment for real-time screen-contentMarco Paniconi
For real-time screen content mode when the short_circuit flat_blocks feauture is enabled: reset segment to 0 for coding block if its flat, regardless of temporal source_sad. Reduces some artifacts on flat areas. Change-Id: I9620e424bedc5a13f87cc4f66af7c0e86043c89c

2018-07-23Add prune_ref_frame_for_rect_partitions featureHui Su
Add a speed feature to prune reference frames for rectangular partitions. Rectangular partition RD search happens after square partition RD search. With this feature, we keep record of the ref frames picked by square partitions, and only consider those ref frames during rect partition RD search. With this feature on, the computation cost of rect partition RD search is greatly reduced, so we can afford to skip rect partition RD search less aggressively. Overall, both compression and encoding speed are improved. Only speed 0 is affected. Coding gains: lowres midres hdres ovr psnr 0.00% -0.36% -0.37% avg psnr 0.00% -0.36% -0.36% Tested encoding speed with QP=40 on about 30 sequences. Speed gains: lowres midres hdres average 13.4% 7.1% 6.1% max 28.0% 12.0% 9.8% Change-Id: Id5f36dd2ac75028ae98550d67b0a524aa251b692

2018-07-20Fixed "MAX" boost for static kf sections.Paul Wilkins
Apply a fixed maximum boost for static key frame groups / slide show content (if > 8 frames long). This insures sufficient boost on shorter sections whilst preventing excessive boost on longer sections. Change-Id: I5b857dab023d674cfd55bced3437f3bce3b4f1cb
2018-07-20Fix issue with short static KF groups.Paul Wilkins

2018-07-20Improved coding on slide show content.Paul Wilkins
This patch adds in detection of slide show content and allows for coding of long GF only groups up to a length of 240 frames rather than coding a large number of shorter ARF groups that gradually lower the Q. In test samples this patch gave rise to a substantial improvement in overall psnr and a drop in data rate. In some cases the average psnr fell, however, with the boost and minQ values set as they are. This is to be expected because average psnr is dominated by the best frames in the sequence and previously a relatively poor key frame could be followed by progressively better alt refs. For example a key frame at q7.5 but subsequent alt refs improving it to lossless. For slides displayed for several seconds, savings of >= 20% (or commensurate quality gains) are likely. This patch allows for long GF groups in static sections before and after complex transitions (e.g. fades) with one or more normal ARF groups during the transition. However, it enforces a single "normal" length GF group after the transition before any extended group is allowed. The reason for this is that the ARF that spans the transition my not have a very high quality and hence may not be a good GF for the long static section that follows.

2018-07-18vp9: Screen-content after slide-change: increase refresh rateMarco Paniconi
For screen-content real-time CBR mode: on a detected slide change that is encoded at max Q (to prevent excessive overshoot), increase the perc_refresh in the cyclic refresh following the slide change. Use counter to increase refresh up to some #frames from slide change. This is attempt to increase quality ramp-up after slide change without causing too much excess overshoot.
