2018-01-11vp9: Skip encoding of enhancement layers on the fly.Marco
For SVC: if an enhancement layer (spatial_layer > 0) has 0 bandwidth, skip/drop the encoding of the layer. This allows the application to dynamically disable higher layers for SVC. Add flag to signal the skip encoding, this is needed to modify the packing of the superframe when the top layer is skipped/dropped. Also moved some updates (current_video_frame counter and the last_avg_frame_bandwidth) to the postencode_update_drop_frame(). Added datarate unittest for dynamically going from 3 to 2 and then back to 3 spatial layers. Change-Id: Idaccdb4aca25ba1d822ed1b4219f94e2e8640d43

2018-01-10Add zoom break out for kf boost loop.paulwilkins
Adds a breakout threshold to key frame boost loop. This reduces the boost somewhat in cases where there is a significant zoom component. In tests most clips no effect but a sizable gain for some clips like station. Change-Id: I8b7a4d57f7ce5f4e3faab3f5688f7e4d61679b9a
2018-01-10Fix kf detection in some slide shows.paulwilkins
This fix improves detection of key frames in slide shows. In particular it helps if the slides are pictures of varying formats as in a sample provided by yclin@. This change does not impact any of the clips in our standard tests but for the example slide show test clip helped global psnr by several db and resolved a serious visual quality issue.

2018-01-05vp9-svc: Use eightap_smooth for downsampling at low resol.Marco
Switch from bilinear to eighttap_smooth for frame-level downsampling at low resolutions (<= 320x240). avgPSNR/SSIM metrics increase from ~0.5-2% (all clips positive gain), for 2 and 3 spatial layer SVC, with 3 temporal layers. Small/negligible increase in encoding time (< 1%). Change-Id: I758472fc4fddd51d87f13c9d1a1cd4986ef5d41f
2018-01-05Fix bug in use of zoom metric as part of arf breakout.paulwilkins
The in/out (or zoom metrics) in accumulate_frame_motion_stats() are in effect a % of the blocks that have a motion vector pointing either towards or away from the center. As such they are already normalized in terms of image size and the thresholds against which these are tested should be image size independent. In practice a zoom either in or out is an indicator for a shorter group length so the abs value is more important as a breakout clause. This patch fixes the threshold test. Clips without noticeable zoom show no effect but some with strong zooms such as "station" show a big gain (5-10%). Average psnr-hvs gain on hdres set was 0.292% Change-Id: I4f97a72b0e273e4e844ade15285749c32cd81c1c
2018-01-04vp9: Increase convergence speed of noise estimation.Marco
Increase the recursive average factor from 15/16 to 3/4 to make the noise estimation respond faster. Small/neglible change on low noise content, but better denoising for noisy content. Also encoder speedup of ~2-3% observed on some noisy clips. Change-Id: I9dd02fe961ca24b411fe4c2732f814bf1e9a7f9f

2017-12-21Don't force inlining for msvc targets.Ralph Giles
INLINE is defined as __forceinline for vs* configs, but is the normal, compiler-discretion inline for gcc/clang configs. This makes many functions very large when building for windows targets, much larger than they are elsewhere. Use '__inline' as a consistent definition to get consistent function sizes. Although Visual Studio documentation says that 'inline' is only available in C+ code. This is probably incorrect, since Visual Studio 2017 accepts C99 'inline' even when passed /TC. Nevertheless, this commit uses the recommended '__inline' for consistency. Thanks to David Major for the diagnosis. Change-Id: Ib0b31a3afcea77822c84fe3c6cd452add66d825a

2017-12-19vp9-svc: Add layer bitrate targeting to SVC datarate tests.Marco
Modify and update the SVC datarate unittests to verify the rate targeting for each spatial-temporal layer. The current tests were only verifying the rate targeting of the full SVC stream, not individual layers. Also re-enabled a test that was disabled. This is a stronger verification of the layered rate control for SVC for 1 pass CBR encoding. Added PostEncodeFrameHook, needed to get the layer_id and update the layer buffer level.

2017-12-13vp9: Update to SVC datarate tests.Marco
With recent fixes to rate control for SVC the buffer underrun in the tests does not happen, so comment and TODO can be removed. Also, in some of these SVC tests, replace the HD clip with the corresponding VGA clip, which has > 400 frames. For the (niklas) HD clip: it has only 60 frames but the test was running up to 300 frames. Fixed it to 60 frames. Keep some tests with the HD clip, needed for the 4 thread and 5 level scaling test.

2017-12-13vp9: Reset rc flags on some configuration changes.Marco
For large dynamic changes in target avg_frame_bandwidth, or a change in resolution, via the update in change_config()), reset the under/overshoot flags (rc_1_frame, rc_2_frame) to prevent constraining the QP for the first few frames following the change. For SVC use the spatial stream avg_frame_bandwidth in reset condition. For the avg_frame_bandwidth condition, use fairly large threshold (~50%) for now in reset. This allows for better/faster QP response if, for example, application dynamically changes bitrate by large amount. Change-Id: Ib6e3761732d956949d79c9247e50dba744a535c0
