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

2017-12-19vp9: Reset buffer level on large bitrate changes.Marco
For a large change in the target avg_frame_bandwidth, via the update in change_config()), reset the buffer_level to optimal_level. This fix prevents possible frame drops, where for example, encoder suddenly goes from lower to higher bitrate. Change-Id: I2f844c41d04c01240e85f574e59d2b9075c7eb6d

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

2017-12-08Bug fix for second reference stats.paulwilkins
Immediately following a key frame the trailing second reference error in the first pass stats will be based on a reference frame from the prior key frame group and will thus usually be much larger. This fix eliminates that effect (which typically triggers a short arf group immediately after a key frame). It also changes the accounting for the first frame in each new arf group. This change gives large gains on a couple of clips that contain mid sequence key frames (e.g. 6% on 1080P tennis). Overall there was a net gain in PSNR and PSNR-HVS ~(0.05- 0.4%) and mixed results for SSIM (+/- 0.2%). Change-Id: I8e00538ac2c0b5c2e7e637903cac329ce5c2a375

2017-12-06vp9-svc: Set downsampling filter for VGA layer.Marco
Downsampling filter for SVC was set to subsample (phase 0) for HD -> VGA, and bilinear averaging (phase 8) for VGA -> QVGA. This change makes it bilinear averaging for HD -> VGA. Given the recent commit 9f9d4f8, quality is improved with this change: avgPSNR/SSIM up ~1-3% on HD clips in RTC set. Speed decrease of ~1% for 3 layer SVC.

2017-12-06vp9: Nonrd-pickmode: move some early exits up.Marco
Move the early exit checks on usable_ref_frame and skip_ref_find_pref up before the check on flag_svc_subpel. The code under flag_svc_subpel requires frame_mv to be set for the golden/spatial reference, which is only set if the both those exits don't pass. No change in behavior. Change-Id: Id304276c745eeb389ff85fa2dcf510d5976bc413
2017-12-05vp9-svc: Allow for nonzero motion on spatial reference.Marco
For nonrd pickmode on a given spatial layer, the spatial (golden) reference was always only using zeromv for prediction. In this patch if the downsampling filter used for generating the lower spatial layer is an averaging filter (nonzero phase), we allow for subpel motion on the spatial (golden) reference to compensate for the shift. This is done by forcing the testing of nonzero motion mode to compensate for spatial downsampling shift. Improvement for cases where the downsampling is averaging filter. In the current code this is only done for generating resolutions <= QVGA. Improvement for avgPSNR/SSIM on RTC set for speed 7: ~1.2%. Gain is larger (~2-3%) for VGA clips with 2 spatial layers. ~1% speed slowdown for 3 layer SVC on mac. Change-Id: I9ec4fa20a38947934fc650594596c25280c3b289

Avoids duplicate computation of UV predictor. Bit-exact when static_threshold is zero. Small/neutral difference on RTC set with nonzero static_threshold (since UV predictor won't be skipped with this change). Small speed gain, ~1-2%, at speed 8. Change-Id: Iba8d22a307768b391e29d63c9826aac5a4d9c285
