2018-11-07vp9-screen-content: Adjust condition for large search areaMarco Paniconi

2018-11-06vp9: postencode drop frame for screen content in CBR.Jerome Jiang
Encode the next frame at max q. For layers: post_encode_drop is only check on base spatial layer, and if base is post-encoded-dropped, then whole superframe is dropped. Added API to guard postencode dropping. Turned off by default. Added unittest. BUG=b/112990050 Change-Id: I42fee279014aca616f7a4d9b582cb2bf5da2f2e7
2018-11-06vp9 screen-content: Adjustments for screen content.Marco Paniconi
Increase search area, use NSTEP, and in some cases avoid bsize below 16x16. This for base spatial layer when many blocks in the frame have motion (from scene detection analysis). Improves quality for scrolling motion. Change-Id: If77b43e738a6c43610d4727a95712667088db564

2018-11-06Modified key frame detection.Paul Wilkins
Address poor key frame detection in some content. This patch improves on poor key frame / scene cut detection observed with some test content. The content in question was letter boxed film style material and also had quite low contrast. For both 1080P and 4K multiple genuine scene cuts were being missed. The changes alter the conditions for marking a transition as a "flash" rather than a scene change. The new code still deals well with genuine flashes as observed in the "crew" test clip, without falsely flagging some of the the scene cuts in the "film" test clip. The new film test clip also had some "flash" frames caused by a lightning effect and in one case a flash occurred right before a scene change. This caused a misplacement of the key frame but has been addressed by a new clause that requires the coded error for the next frame after a candidate key frame to be lower than the current frame. The patch also changes the way in which neutral blocks (similar inter and inter error) are handled in the candidate key frame decision in a way which hopefully handles the letter boxed format better. During wider testing some film clips still had missed key frames but this patch does improve things. In the case of the initial test clip the encoder correctly marks all 3 scene cuts vs 0 before the patch. Testing with our standard (mainly short single kf) derf and NF test clips is neutral.

2018-10-29Properly space qp in q mode for multi-layer ARFJingning Han
Space the quantization parameter distribution according to the layer depth for multi-layer ARF coding structure. This allows lower layers to have relatively smaller quantization parameters than higher layers. It improves the compression performance in constant q mode for multi-layer ARF system: avg PSNR overall PSNR SSIM lowres -0.33% -0.31% -1.44% midres -0.29% -0.38% -1.14% hdres -0.27% -0.49% -1.02% Change-Id: I9cfe2f27e6c0029c30614970a46de3045840264e
