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
For real-time screen-content mode: makes the scene/slide change detection more robust. Change-Id: I28d8d28b42bb92d527811f814bf14bbbbb53ab25

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

2018-08-01Use mesh full pixel motion search to build the source ARFJingning Han
Append mesh search to the diamond shape search to refine the full pixel motion estimation for source ARF generation. It improves the average compression performance.

The ".syntax unified" directives in a few source files aren't valid ADS assembly directives, and they break compilation for windows, since ads2armasm_ms.pl doesn't handle them. Explicity add them via ads2gas.pl and ads2gas_apple.pl instead, and tweak one instruction to be valid unified syntax. Change-Id: I37f1709f163d11474597161fe02eb433859cb9b8
