2018-08-03vp9: Adjust qp_thresh on slide change overshoot detectionMarco Paniconi
For real-time screen-content mode: increase the qp_thresh for max_Q setting on slide changes. This will make bitrate spikes less likely on slide changes. Change-Id: Ie13524a06490214456b1c9c042a864ea0d0750c5
2018-08-02vp9: Add zero_temp_sad count to scene detection.Marco Paniconi

2018-08-02vp9: Increase min_thresh for slide change detectionMarco Paniconi
For real-time screen-content mode: increase min_thresh to avoid some false detection. Change-Id: I3e93dea63cbd65e3ad5d0af7eabf0d3686fe9943
2018-08-02vp9: Disable re_encode_overshoot feature for speed >= 6.Marco Paniconi
For real-time screen content mode: for speed >= 6 disable the re_encode_overshoot feature. This means for speed >= 6 the Q and rate control is reset on slide changes based on the scene/slide detection and the current Q (and not on a first pass encoded frame at current Q). This reduces encode time on slide changes, but may be less accurate in deciding when to reset/max-out the Q. Change-Id: Id0fdcafd55bc43bd8b3afee211e524f37c8ddce6

Use diamond search for full pixel motion estimation to build the temporal dependency model and the source arf frame. This gives better full pixel motion estimation accuracy.

2018-07-24vp9: Modify logic for flat blocks in nonrd-pickmode.Marco Paniconi
For real-time screen content mode: when slide change is detected, for spatially flat blocks (source_variance = 0) on the re-encoded frame, skip inter modes (so force intra) if non-zero temporal variance is detected for the coding block. Add flag to keep track of re-encoded frame at max Q. Reduces artifacts on slide change. Change-Id: I28151f412aba6ab8cb03f30087c7ce16d443654b
2018-07-24Limit min Q for normal frames.Paul Wilkins
This patch limits the active min Q for normal frames based on the previous KF/GF/ARF. In a few cases, especially at the end of a clip where there has been systemic underspend, (as is often the case with slide shows), this prevents the encoder rapidly dropping Q on normal frames (just to try and use up bits), such that they end up with a lower Q than the key frame / GF / ARF off which they key.
